Fire-resistant coupling - for use wherever fire protection is prescribed law STRAUB FIRE-FENCE connects the functional design and the latest technology. STRAUB FIRE-FENCE is based on proven technology connector, developed for the shipbuilding industry. Meanwhile, STRAUB-FIRE-FENCE is also successfully used in tunnel construction, with fire lines (VDS), in the development of the engine, etc.. Connector except protection from flames, space saving and thanks to the improved design of low weight. Fire intumescent cloak swell and wraps around the joints, in order to protect them. Coupling in this retains full ability to work - without any distractions. STRAUB-FIRE-FENCE impresses with its innovative mode of performance, but at the same time retains the traditional characteristics of classic STRAUB pipe joints. For use wherever fire protection is required by law Diameter 26.9 to 406.4 mm The temperature ranges indicated are based on the use of EPDM sealing sleeves. EPDM and NBR sealing sleeves are used by default. Various coupling sizes also available with FPM/FKM sealing sleeves (Temperature range: -20°C to 180°C). Various coupling sizes also available with H-NBR sealing sleeves (Temperature range: -20°C to 125°C). All diameters and designs available plus accessories (strip inserts, stiffening rings, fitting pliers, tensioning straps) can be obtained from the technical manual. Construction and design of the STRAUB pipe couplings comply with the directives of DIN 86128-1 and 86128-2.
