3 1 Production Process 01 The basic raw materials used in the FLOWTITE pipe s manufacturing are resin, fibreglass and silica sand. Usually unsaturated polyester resins are used since they give good performance for sewer and water applications. FLOWTITE pipes are manufactured using the continuous advancing mandrel process, which represents the state of the art in GRP pipe production. This process allows the use of continuous glass fibre reinforcements in the circumferential direction. For a pressure pipe or buried conduit, the main stress is in the circumferential direction, thus incorporating continuous reinforcements in this direction yields a higher performing product at a lower cost. Using technology developed by material specialists, a very dense laminate is created that maximizes the contribution from three basic raw materials. Both continuous glass fibre rovings and choppable roving are incorporated for high hoop strength and axial reinforcement. A sand fortifier is used to provide increased stiffness by adding extra thickness, placed near the neutral axis in the core. With the Flowtite dual resin delivery system, the equipment has the capability of applying a special inner resin liner for severe corrosive applications while utilising a less costly resin for the structural and outer portion of the laminate. release film Taking advantage of the winding process, other materials, such as a glass veil or polyester veil can be used to enhance the abrasion resistance and the finishing of the pipe. The figure above shows a typical cross section of a pipe laminate. This section, as well as the way of applying and placing different raw materials, can differ depending on the pipe application. glass-fibres Exterior Surface Chop Layer roving rack Outer Structural Layer Core Inner Structural Layer Barrier Layer sand and chopped glass saw Interior Layer winder engine curing area surface veil computer & control panels finished pipe dosing pumps day tank bull tank 3

5 4 Quality Characteristics Raw Materials Raw materials are delivered with vendor certification demonstrating their compliance with Flowtite quality requirements. In addition, all raw materials are sample tested prior to their use. These tests ensure that the pipe materials comply with the specifications as stated. Raw materials should be, according to Flowtite quality requirements, pre-qualified in such a way that their suitability to be used in the process and in the final product is demonstrated. Raw Materials used in pipe production are: Glass Resin Catalyst Sand Additives Only Flowtite approved raw materials can be used for the production of the Flowtite pipe. Glass Glass is specified by tex which is = weight in grams/1000 meters length Hoop roving: Continuous roving used in different tex for the production of the Flowtite pipe Chop roving cut directly on the machine to provide strength in different directions. Resin Only qualified resin for the winding process. Usually it is delivered in drums or bulk. The resin is prepared in day tanks at the winder. Normal application temperature is 25 C. Resin is delivered from the producer and may be diluted before use on the winder with styrene to reach the required and acceptable viscosity, as defined by Flowtite Technology. Catalyst The right amount of catalyst is added to the resin for curing the mix right before application on the mandrel. Only approved catalysts are used in the manufacturing process of the Flowtite pipes. Additives Additives are used as accelerator for the resin and are mixed with it in the day tanks. The additives are available in different concentration and may be diluted by the producers in mineral spirit to reach the required concentration needed for the production of the Flowtite pipes. 4.2 Physical Properties The manufactured pipe s hoop and axial load capacities are verified on a routine basis. In addition, pipe stiffness and deflection tests are carried out in accordance with our internal Flowtite quality regulations. 4.3 Finished Pipe Properties 100% of all finished pipes for gravity sewer are checked for the following: Visual inspection Wall thickness Section length Diameter 4.4 Other Quality Characteristics More detailed information about many other quality characteristics such as: Long-term Ring Bending Hydro-testing Surge and Water Hammer Load Capacity Values Hoop Tensile Load Capacity Axial Tensile Load Capacity Flow Velocity UV Resistance Poisson s Ratio Flow Coefficients Abrasion Resistance can be found in our brochure Technical Characteristics of Flowtite pipes. Sand Sand is added to the core of the pipe and the inner layer of couplings. High quality silica sand must be within the Flowtite specifications for approved raw material. 5

8 6 Pipe joining Double Bell Coupling (FSC) Flowtite pipe sections are typically joined using FLOWTITE gravity sewer couplings (FSC). Pipe and couplings may be supplied separately, or the pipe may be supplied with a coupling installed on one end. The FLOWTITE coupling utilises an elastomeric gasket for sealing. The gasket sits in a precision-machined groove in each end of the coupling and seats and seals against a spigot surface.! Note: Detailed installation instructions can be found in our separate publications for pipe installation. Joint Angular Deflection The joint is extensively tested and qualified in accordance with ASTM D4161, ISO DIS8639 and EN Maximum angular deflection (turn) at each coupling joint, measured as the change in adjacent pipe centre lines, must not exceed the amounts given in table below. Pipe Coupling Deflection angle Radius of curvature Figure 6-1 Offset and Radius of Curvature Offset The pipes must be joined in a straight alignment, but not all the way to the home line, and thereafter deflected angularly as required (Figure 6-1).
