K7 Ductile Iron Pipes can handle less pressure than DI K9 Pipes. To get the right DI K7 pipes specifications required, all one has to do is contact the many wholesalers, retailers, manufacturers and exporters online, who sell this product. DI K7 pipes pressure rating varies and this would be based on the Nominal Diameter and the Nominal Wall Thickness of the pipes. Complete details of ductile iron pipes price list can be obtained by doing an online search for the various retailers, distributors, manufacturers, wholesalers and exporters of this kind of product. Weight of DI K7 pipes would vary as this would be dependent on the size of the pipe. DI pipes – K7 price list, can very easily be obtained by running a few relevant searches online and getting in touch with the various sellers of this type of product. DI pipe K7 means, 7 is the pressure class of the DI pipe and 7 represents the pipe’s internal pressure withstanding capacity. Ductile iron pipe specification is as follows ANSI/AWWA C104/A21.4, ANSI/AWWA C111/A21.11, ANSI/AWWA C150/A21.50, ANSI/AWWA C151/A21.51, ANSI/AWWA C105/A21.5, ANSI/AWWA C116/A21.16, ANSI/AWWA C600, ANSI/AWWA C115/A21.15, ANSI/AWWA C153/A21.53 and ANSI/AWWA C110/A21.10. DI K7 pipes specifications would vary and this would be based on the basic dimension and the thickness of the ductile iron pipes. In K7 Ductile Iron Pipes, the 7 is representative of the internal pressure withstanding capacity of this kind of ductile iron pipe.
