Ductile iron pipes for water conveyance:
Product standards: BS EN545:2002, ISO2531:1998


 


1) Pipes are supplied in standard length of 5.5/6.0m, short length pipes as per respective standards can be supplied
2) In addition to Class K9 pipes, We also supplies K7, K8, K10, and K12 classes of pipes
3) The thickness can be determined by the formula-e=K (0.5+0.001DN)
4) PFA (allowable operating pressure) is the internal pressure, exclusive of surge, that a component can safely withstand in permanent service
5) PMA (allowable maximum operating pressure) is the maximum internal pressure, including surge, that a component can withstand for a relatively short duration, when either fixed above ground level or laid and back-filled underground in order to measure the integrity and leak tightness of the pipe.
