Connection of polyethylene pipes
Peštan ULTRA PVC pipes and fittings for waste water are connected over sockets. The water resistance is achieved through the sealing rings made of EPDM rubber (EN 681), which are inserted into the socket.
EPDM rubber, which is located in socket has two sealing surface and an additional plastic ring that is made in a different color. Rubber has a unique design which provides the part of the rubber and plastic together as a sealing element.
Installation, connection and testing of ULTRA PVC piping is carried out according to the current European standard EN 1610.
Pipes carry a label with snowflake in accordance with EN 1401. The pipes are tested in accordance with EN 744 and EN 1411, which unlike of EN 1401 go a step further. This standard stipulates the release of metal weight of 8 kg with a height of at least one meter to the pipe, at a temperature of -10°C. Since there were no cracks or deformation as result of testing of Pestan PVC Ultra, the mark of snowflake is allowed to be used on pipes. This test simulates the real situation on the construction site where large pieces of stone can fall onto the pipe until it is in a trench.
