Sclairpipe Versatile high density polyethylene pipe Sclairpipe
Flexible lightweight pipe for your most demanding applications Sclairpipe high density polyethylene (HDPE) pipe represents the latest advances in both material and manufacturing techniques. Since 1968, Sclairpipe has been proven in a wide range of municipal and industrial piping applications. It has been used extensively in the municipal market for gravity sewers, sewage forcemains, and pressure water systems. KWH Pipe has special expertise in marine installations of Sclairpipe, including river and lake crossings; and river, lake and deep ocean intakes and outfalls. Lighter. Stronger. Chemical Resistant. Sclairpipe is a tough, lightweight, solid wall pipe with a smooth internal surface. Available in various diameters from 3/4" to 63" it can handle internal pressures of up to 300psi. It is a well suited alternative to copper, PVC, ductile iron and concrete pipe in a variety of different applications. Sclairpipe weighs approximately 1 /10 that of a similar sized concrete pipe. Handling requires a minimum of heavy equipment and Sclairpipe can easily be assembled on ice or through wet marshy areas. It will not corrode, tuberculate or support biological growth, making it the material of choice in harsh environments. Sclairpipe is inert to salt water and to chemicals likely to be present in sanitary sewage effluent. Sclairpipe has a smooth ID and maintains its flow capability over time - Hazen Williams C Factor remains 150, even after years of use. Easier to Transport and Install. Leak Proof. Sclairpipe is much easier to handle and install than heavier, rigid concrete pipe, offering potential cost savings during the construction process. It is structurally designed to withstand impact, especially in cold weather installations when other pipes are prone to cracks and breaks. Sclairpipe will float even when full of water. For marine applications long lengths of pipe can be assembled on shore and then floated into position. 2 Sclairpipe
Thermal butt fusion provides an economical and fast method of delivering a complete, long, continuous length of pipe. Thermal fusion eliminates potential leak points every 8-20 feet commonly found with gasketed (or bell or spigot) pipe materials. The fused joints provide a continuous leak proof system that eliminates the risk of joint leakage due to ground shifting. Fused joints are fully restrained and as such may reduce or eliminate the need for expensive thrust blocks. With Sclairpipe infiltration and exfiltration problems are eliminated. Cost Effective. Permanent. Sclairpipe offers distinct advantages. It can be installed on a curve to a radius as small as 25 times the nominal pipe diameter to eliminate many fittings required for directional changes in piping systems made from other materials. In addition, the flexibility of Sclairpipe allows it to adapt to uneven ground, unconsolidated river bottoms and excavated underwater trenches without the need for expensive foundations or minor degree elbows. It is well suited for dynamic soils and areas prone to earthquake. Sclairpipe is cost effective in both the short and long term. The fact that it is lightweight makes it easier to transport and install. The fact that it is leak proof and fatigue resistant means years of maintenance free use. The Plastics Pipe Institute estimates the service life for HDPE pipe to conservatively be 50-100 years.

It is lightweight, flexible, durable and abrasion resistant. It is virtually leak proof, and can withstand corrosive chemicals, acids or salts commonly found in mines. Sclairpipe combines strength and durability in above ground applications and is UV resistant. Irrigation Sclairpipe is a cost effective solution for irrigation and agricultural drainage applications such as river and canal diversion, agricultural irrigation systems and pipelines, and water conservation. It is lightweight, flexible and leak proof, resistant to corrosion and salt water, and joints can be heat-fused on site for ease of installation. A Sclairpipe irrigation system will withstand the test of time. Heating & Cooling Sclairpipe has proven to be a strong, leak proof and chemically inert solution for district cooling applications including dual-purpose projects providing cooling and potable water. It can be assembled on shore in a continuous flexible length, floated on the water s surface and then sunk by a controlled process. The pipe can also be manufactured in specific lengths and connected on site by flanges with the aid of marine divers. Sclairpipe pipe s resistance to both corrosion and zebra mussel fouling makes it an ideal solution. Sclairpipe 5
Choose the size that s right for you Sclairpipe is available in standard Dimensional Ratio s (DR s), in sizes ranging from 3/4 to 63 in diameter. The Dimensional Ratio relates the minimum wall thickness of the pipe to its outside diameter, and is important to define the pressure rating of a particular pipe. Coiled pipe diameters range from 3/4" and 1" Copper Tube Size (CTS) and 3/4" to 3" nominal outside diameters in Iron Pipe Sizes (IPS). The maximum continuous operating pressure stated is based on a PE3408/3608 (Per ASTM D3350) 1 material for the indicated DR and is based on water service at 73 F. 1 Sclairpipe is also available from higher density bi-modal resins, having enhanced performance characteristics.

Innovative joining methods and equipment Sclairpipe piping systems can be assembled by heat fusion (butt, electrofusion, socket and saddle fusion), flanged connections, compression couplings and various mechanical couplings. The superior performance of Sclairpipe results from the combination of pipe and fittings designed to work together as a complete system. A full range of pressure rated fittings is available to suit any application. The most popular method of joining Sclairpipe is thermal butt fusion. This fast and economical technique permits the quick assembly of long continuous lengths and the joining of fittings to the pipe. The fused joints are as reliable and strong as the pipe itself, fully restrained, providing continuous leak proof systems. Our skilled fusion specialists are available to assist in the most efficient installation of your Sclairpipe system. Their experience in on-the-job handling, installation and set-up of polyethylene pipe and their pre-job planning capabilities ensures you of a superior installation. Sclairpipe fusion specialists can train and assist your personnel on your joining equipment. Sclairpipe 9
Fabricated fittings complete any system KWH fabricated fittings are available as FM Approved items. Please contact your KWH representative for styles and sizes. KWH Pipe believes that every element of your piping system should be carefully designed to work together in a cost-effective manner. We provide a wide range of complimentary fittings, proven over years of service, to meet the requirements of just about any piping system. Fabricated fittings for use in pressure service are manufactured in the same diameters as Sclairpipe but with heavier walls than are used in the piping system. This results in a fitting with a pressure rating which is greater than or equal to the pipe itself. Unless specifically stated otherwise, the additional wall thickness is on the ID. The butt weld ends of the fittings are counter bored to meet the wall thickness of the mating pipe. KWH Pipe recommends that fittings be ordered by EDR (Equivalent Dimensional Ratio). The pressure rating of the EDR fittings is the same as that associated with the DR of the matching pipe. All fabricated fittings can be supplied with either flanged ends and/or plain ends for field butt fusion to the piping system. FM approved fittings are also available. Please visit the Sclairpipe Fittings section of our web site (www.kwhpipe.ca) to download specification sheets on all standard fittings available. Elbows Elbows for Sclairpipe systems are designed for pressure service and are fabricated from pipe typically 1 standard (SDR) DR heavier than the adjoining pipe. The result is a fitting with the same pressure rating as the main line pipe. The ends of the fitting are counter bored to match the wall thickness of the pipe to which it is being connected. Elbows available in IPS and DIPS sizes. Mitered Tees & Crosses KWH Pipe produces fully pressure rated tees up to 48" in outside diameter. These mitered tees and crosses intended for pressure service are fabricated from pipe that is 2 standard (SDR) DR s heavier than the adjoining pipe. The result is a fitting with the same pressure rating as the main line pipe. The ends of the fitting are counter bored to match the wall thickness of the pipe to which it is being connected. Mitered tees and crosses are available in IPS and DIPS sizes. 10 Sclairpipe
Sidewall Tees As an alternative to conventional reducing tees, our engineered sidewall tees are designed to provide 90 branch reductions off the mainline pipe. Sidewall tees are available in IPS and DIPS sizes. See the fittings section on our website for size ranges and details, www.kwhpipe.ca. Laterals KWH Pipe produces 45 and 60 laterals up to 42" in outside diameter. These laterals are fabricated from pipe with a heavier wall than in the matching pipe. The ends of the fitting are counter bored to match the wall thickness of the pipe to which it is being connected. Laterals are available in IPS and DIPS sizes. Concentric Reducers KWH Pipe also offers concentric reducers that are designed to have a pressure rating equal to a polyethylene pipe with the same DR. We also offer a compact style for significant cost savings. The same high quality resin and extrusion processes used in the manufacture of Sclairpipe is used to produce these reducers. Sclairpipe 11
Polyethylene Stub-Ends & Flange Adapters To join Sclairpipe to other piping materials, ancillary equipment, or to special fittings, a mechanical fitting is usually required. For these types of connections, a flange assembly is the recommended method. This assembly consists of a slip-on metal flange and a polyethylene flange adapter or stub-end. The stub-end or flange adapters carry the same pressure rating as the pipe and are butt fused to the pipe end. The stub-end/flange adapter must be the same DR rating as the pipe to which it is joined. Slip-On Metal Flanges Stock flanges are available and made from ductile iron. KWH Pipe can also supply flanges from other materials for specific applications. The metal flanges are drilled to ANSI 16.1/16.47/16.5, Class 125/150 bolt circles and AWWA C207. Flanges can be supplied with corrosion resistant coatings if required. Injection Molded Fittings KWH Pipe offers a full line of molded fittings, in all common configurations. The resins used to produce these components meet the same standards and specifications as is used to produce Sclairpipe and conventional fabricated fittings. Molded fittings are available with socket fusion or butt fusion ends. 12 Sclairpipe

Weholite Lightweight Pipe System Weholite
The lightweight pipe that takes a heavier load Weholite pipe is large diameter, profile wall pipe made from high-density polyethylene (HDPE) resin. Designed for gravity and low-pressure applications, Weholite s raw material properties have been combined with patented structural wall technology to create a lightweight engineered pipe with superior loading capacity. It is used to convey liquids or air, under ground or above ground, in low-pressure applications. Lighter. Stronger. Chemical Resistant. Weholite pipe is much lighter than similarly sized concrete pipe. Combine this with longer manufacturing lengths and Weholite allows you to achieve savings in labour and equipment. Weholite HDPE pipe will not corrode, tuberculate or support biological growth, making it the material of choice in harsh chemical environments. It is inert to salt water and the chemicals likely to be present in sanitary sewage effluent. Like all HDPE pipe, Weholite has a smooth ID that maintains its flow capability over time. The low Manning s roughness factor of 0.01 remains constant, even after years of use. Easier to Transport. Easier to Install. Leak Proof. Weholite pipe is much easier to handle and install than heavier, rigid concrete or metallic pipe. This means potential cost savings during the construction process. It is structurally designed to withstand an impact, especially in cold weather installations when other pipes are prone to cracks and breaks. Weholite pipe is usually joined by a thermal fusion process (extrusion welding) to form a joint that is as strong as the pipe itself. Extrusion welding eliminates potential leak points every 8-20 feet commonly found with concrete, PVC and ductile iron pipe. Since fused joints are selfrestraining, costly thrust restraints or thrust blocks may not required. 2 Weholite
Extrusion welded Weholite pipe is leak proof. The properties of HDPE pipe and the thermal fusion method of joining produces a continuous pipeline, eliminating the risk of leakage caused by shifting unstable soils. A continuous Weholite pipeline eliminates the joint infiltration and exfiltration problems experienced with other pipe materials. Cost Effective. Permanent. Weholite pipe offers distinct chemical and physical advantages over concrete or iron pipe. It can be bent to a radius 200 times the nominal pipe diameter to eliminate many fittings required for directional changes in piping systems made from other materials. In addition, the flexibility of Weholite pipe makes it well suited for dynamic soils and areas prone to earthquakes. Weholite is cost effective in both the short and long term. The fact that it is lightweight makes it easier to transport and install. The fact that it is leak proof and fatigue resistant means years of maintenance free use. The Plastics Pipe Institute conservatively estimates the service life for HDPE pipe to be 50-100 years.

Hydroelectric Large diameter profile wall Weholite pipe is an ideal solution for hydroelectric applications such as: input lines to hydro powerhouses, turbine feed water supply and water diversion. It is lightweight, which makes transportation and installation easier. The flexibility of the pipe allows for large radius bends, which is important for water diversion where the terrain may control the area of installation. Industry Long-term reliable piping solutions are always in demand for a wide range of industrial applications. Large diameter profile wall Weholite offers resistance to corrosion, abrasion and chemicals that industry requires. Odorous compounds are released from many industrial processes, waste disposal and recycling. A Weholite biofiltration system is a simple, low cost technology that can reduce odour emissions by as much as 95%. 4 Weholite
Irrigation Weholite HDPE pipe has proven to be an ideal solution in irrigation and agricultural drainage applications including: river and canal diversion, agricultural irrigation systems, underground irrigation systems, irrigation pipelines, water conservation and safety. The properties of Weholite including strength and durability ensure that your irrigation system will withstand the test of time. Heating & Cooling Weholite pipe has proven to be a strong, leak-proof and chemically inert solution for use as a high volume water intake line for district cooling applications. It has distinct installation advantages due its light weight. In certain shallow depth marine applications the pipe can be assembled on shore in a continuous length, floated into position and then submerged as a continuous structure. Its resistance to both corrosion and zebra mussel fouling make it an ideal solution in lake and river applications. Sewage Systems After more than 30 years use in sewer applications, polyethylene pipe has proven to be a reliable, long-term solution for sewer and wastewater systems. Weholite pipe has distinct advantages over other piping materials. Its resistance to abrasion and chemicals make it a lasting solution. Inflow and infiltration are completely eliminated in wet weather conditions on gravity flow systems. Weholite pipe is also flexible and does not corrode or tuberculate over time. Weholite 5

Product innovation and quality assurance For over 50 years KWH Pipe has been a leader in the design, development, manufacturing and engineering support of polyethylene piping systems. Extensive R&D in the early 1960 s led us to produce 16" diameter polyethylene pipe at a time when many considered this size a technical impossibility. Today KWH Pipe produces 132" profile wall Weholite pipe for a wide range of applications. We have patented an unique welding machine designed for joining pipes using thermally fused extrusion welding to assure leak-tight joints. All KWH Pipe products are manufactured from special, high strength resins with complete quality control maintained from raw material to finished pipe product. KWH Pipe was the first North American manufacturer of polyethylene pipe and fittings to have its Quality Management System registered to the ISO 9001:2000 level. Our strict manufacturing specifications are verified daily, using precise dimensional controls and accelerated long term hydrostatic testing. Our continuous quality control process assures you of long-term pipe performance. Weholite 9
Easy to transport, join and install Since Weholite pipe is lightweight and flexible, it is easy to transport and install. Small misalignments of pipeline can be accommodated by bending the pipe itself. Long lengths of pipe can be ordered to reduce the number of joints and the associated time and expense of installation. Thermal fusion allows for a fast joint that is as strong as the pipe itself and leakproof. Please visit our web site and use our online specification tool for detailed information on pipe selection and installation. Thermal Fusion/Extrusion Welding Thermally fused extrusion welded joints are the recommended joining method. The connection can be made using simple hand-held extrusion equipment. Specialized equipment is also available to join large diameter pipe on both the inner and outer surfaces from inside the pipe. This process enables the pipe to be connected at both the inner and outer pipe walls in a single operation from within the pipe. Equipment can be leased from KWH Pipe and operated by factory trained technicians to provide a leak-proof seal. Simplified Material Handling Light weight and long lengths reduce the material handling requirements at construction and storage sites. In addition, Weholite has high axial (or beam) stiffness that reduces the number of support points required to lift these long lengths of pipe. The durable PE material helps ensure that product damage due to handling is minimized. Wehoseal Joint Wrap Wehoseal Joint Wrap is commonly used to connect Weholite pipe to other piping materials or when Weholite is used to reline other pipe materials. It is made from a shrinkable cross-linked polyethylene material which conforms to the diameter of the pipe when heated. Sleeves can be supplied with additional fiberglass reinforcement for challenging conditions. Installation is performed in the field using a propane torch and a hand roller. Thread-Loc Joint The unique Thread-Loc joint on KWH Pipe s Weholite pipe allows municipal maintenance crews or contractors to rehabilitate deteriorated culverts and sewers without excavation, at a fraction of the cost of replacement. A threaded connection gives a joint that resists infiltration of normal silt and rainwater debris. The Thread-Loc connection is available on sizes from 18 to 132. Thread-Loc Joint not available in 48 and below in U.S.A. 10 Weholite
Grouting Reline Pipe Weholite s high axial stiffness and high resistance to the hydrostatic collapse pressure caused by grouting, simplifies the installation and grouting procedures when using this pipe to reline deteriorated highway culvert pipe. Relining offers substantial savings over replacement of distressed pipe and avoids traffic disruption. Pipe Installation The bedding and backfill requirements for Weholite pipe are the same as those for all plastic pipe. ASTM standard D2321 that applies to PE and PVC plastic pipe installation, is appropriate for describing the process for placement of bedding, and backfill materials on a Weholite pipe installation. Where native materials are suitable, imported embedment materials may not be required. Manhole Installation Weholite manholes are designed in accordance with ASTM F1759. HDPE manholes when used with HDPE piping produce a sewage system that is completely leak-free and is not subject to the corrosion experienced in many sanitary sewage systems. Weholite manholes may be provided with corrosion resistant OSHA ladders, and field cut to the required height. Weholite 11
