The STIDREN system is designed in such a way that the pipes and various connecting pieces are joined quickly and easily by inserting the pipes into the clamp of the connecting piece. The coupling technology enables minimal consumption of time and effort and ensures optimal flow and minimal hydraulic losses. The joints are impermeable to sand and other soil particles. For STIDREN DK pipes, EPDM sealing rings that comply with DIN 4060 and ensure the impermeability of water joints are also used for connecting.
Pipes of dimensions DN 250, 315 and 355 can have an already welded coupling and an inserted sealing ring, so that assembly is even easier and faster.
Prior to joining pipes and fittings, the contact surfaces must be clean and undamaged.
If the required pipe length is shorter than the standard one, cut the pipe straight (with a knife or a fine-toothed saw). Push the plug end into the connecting piece to the limit. If the joints are made with sealing rings, the seal and the joint must be lubricated with a suitable friction reducing agent (grease for rubber seals, silicone oil, soap), which must not damage the seal or pipe.
