PRESSURE PIPES
Product Details
PERSIT pressure pipes are usually produced according to ISO/160-1980 standard. The pipes are produced in standard lengths of five meters with nominal diameters (ND) of 150mm to 1600mm, and working pressure of 6, 9 and 12 atm. Pipes are classified according to hydraulic test pressure (classes 12, 18 and 24). On order pipes with higher working pressure and also according to other standards could be produced.Hydraulic pressure tests are performed on the pipes in the factory.All the pipes undergo tests at twice the recommended working pressure, as shown in table (1):WP = Recommended maximum working pressure.TP = Factory test pressure.STP = Maximum site test pressure.Besides the above internal hydraulic pressure test, on sampling basis, pressure bursting tests, traverse crushing tests, and longitudinal bending tests are also performed.The cement used in the manufacturing is resistant cement - or ordinary Portland cement also, on request, the pipes can be given a bitumen coating.
ERSIT pressure pipes are usually produced according to ISO/160-1980 standard.
