3 Flamco Pipe Support System This catalogue features the range of Boss Flamco Pipe Clips and Accessories available through BSS (UK) branch office warehouses. The various assemblies which can be made up are fully illustrated to enable customers to select the assembly most suitable for their particular applications. The system is designed and manufactured by Flamco BV, Gouda, Holland. APPLICATION & PROTECTION The Flamco Pipe Support System is for use in supporting horizontal and vertical heating and air conditioning pipework within buildings. The thickness of zinc coating on Flamco Pipe Support System components is sufficient to protect them prior to installation and for use without further protection where dry uncontaminated conditions can be guaranteed. All components should be stored as delivered, under cover, in dry conditions. Further protection should be provided where moist conditions may prevail or where fittings may not be easily accessible for regular inspection. Frequency depends on environmental conditions. The BSS (UK) system of branch offices covers the whole of the UK and Eire with a network of well-stocked warehouses to meet the demands of the heating engineer and industrial user. Each branch office has a trained sales and technical staff, both internal and external, who will be pleased to advise you on any heating or pipeline problem. The products supplied by BSS (UK) are generally in accordance with British or other International Standard Specifications where applicable and as interpreted by the manufacturers, and present no hazard to health or safety if properly installed and operated. There are, however, many occasions when goods are ordered from us without any reference being made to their intended use, in which case, the Company must assume that users will take all necessary steps to ensure that the products purchased are suitable for the conditions in which they are intended to operate. Our current catalogues generally indicate the Standards and Classes with which the products comply, but if in doubt, please consult your nearest BSS (UK) Branch. BOSS FLAMCO IS THE EASY AND SIMPLE TO USE PIPE SUPPORT SYSTEM The main advantages gained by using the BOSS FLAMCO pipe support system are: QUICK AND EASY TO INSTALL Saves time and money VERSATILE The system offers many combinations FLEXIBLE Allows for limited pipe movement ADJUSTABLE Allows for pipe falls and level changes EASILY MODIFIED Makes pipeline alterations easy CORROSION RESISTANT Most items zinc coated as standard NOISE REDUCTION The design of certain products helps to reduce pipeline noise BBA APPROVED Products are independently tested to ensure quality and strength Copyright : The drawings and illustrations featured in this catalogue are subject to copyright and must not be reproduced without written permission of the Company. 3

5 Flamco Pipe Support System Introduction...IDEAL FOR ALL WALL MOUNTING APPLICATIONS The wall system is equally adaptable when mounting pipes up or along a wall. The range starts with the simple BM clips which are attached by the woodscrew and plug system right up to the multi hanging cantilever sets....ideal FOR ALL OVERHEAD MOUNTING APPLICATIONS The system has been designed to suit most overhead hanging requirements from a simple run along a concrete ceiling to a multiple hanging requirement. Whichever application suits your requirement you will find the system easy to understand and install. The basic system can also be added to by the use of the many specialist items, such as noise suppression fixtures, expansion units etc. And remember all this is backed up by the technical expertise offered at all BSS (UK) branches. 5

8 Flamco BK, BKI and BKK Hanger Assemblies GENERAL INFORMATION All of the BK, BKI and BKK range of pipe hangers consist of Ball head Sleeve One-piece bracket The ball head of BK pipe hangers gives an axial movement of up to 12 (2 x 6 ). This axial movement ensures that the assembly is not distorted or damaged as the pipe expands because of temperature changes. The length of the sleeve is such that, even after the assembly is fitted, it is still possible to insulate the pipe without affecting the movement of the ball element. Pipes can be installed one below the other without difficulty. BK pipe hangers have a joggle at the bottom of the clip to accoodate a BO or BOK extension piece.

30 Flamco Rail General Information The Flamco rail can be used for various wall and ceiling mountings with a limited number of anchor points required. With the aid of various accessories available, e.g. rail support, nuts and angle brackets, it offers a fully versatile and adjustable system for installing pipework. Flamco rail can be supplied in 6 variations to carry from light to very heavy loads. With the table below it is possible to calculate the correct rail for the load to be carried. R0 R1 Type Rail support nut Cross section cm 2 lx cm 4 Wx cm 3 R0 M..s R1 M..s R2 M..s R3 M..s R4 M..s R6 M 6s * 3.60 R6 M 8s R6 M 10s R6 M 12s Mb* Ncm Max.point loading max. max working load in breaking load in N N Mass kg/m * Max. load with M6 threaded rod. R2 The yield stress of Flamco rail material is at least 240 N/ 2. Note 1: Based on a bending stress of 140 N/ 2. Note 2: For the maximum point loadings the various types of rail must only be used subject to the maximum bending moment (Mb max.). In practice this means that these maximum point loadings may only occur close to the rail fixing points. Rail selection The above data can be used to make the necessary strength calculations. R3 R4 R6 Important It is important to ensure that the load is evenly distributed over the successive suspension points of a pipe. (Every rail is then loaded equally and evenly). Careless adjustment can give rise to large differences in the loads on the rails. When Flamco rail is suspended using Flamco rail support nuts, Flamco haerhead nuts and Flamco washers as shown in the sketch alongside, the point-loading value in the above table may be adhered to. When using R4 rail, Flamco SP rail clamps should be used instead of Flamco rail washers. When using R6 rail, Flamco SP SR rail clamps should be used instead of Flamco rail washers.
