K / C Restrained Joint Ductile Iron Pipe And Fittings Internal Lining Cement

Self-Restrained joint ductile iron pipe:

Restrained joint in which means provided to prevent separation of the assembled joint. All restrained joints shall be
designed to be at least semi-flexible. Produce according to the customer’s requirement.

External coating: Ductile iron pipeline systems can be installed in a wide range of external operating environments, these environments can be characterized according to their aggressively. Pipes shall normally be delivered internally and externally coated. Ductile iron pipeline systems can be installed in a wide range of external operating environments. Coatings specified by relevant International Standards are available as specified.Internal lining:Ductile iron pipeline systems can be used to convey a wide range of raw waters and potable waters. These internal environments can be characterized by their aggressively. Relevant factors to be considered for cement mortar linings without seal coats are given; Linings specified by relevant International Standards are available as specified.

Usage:

Much of the production of ductile iron is in the form of ductile cast iron pipe, used for water and sewer lines. Ductile cast iron pipe is stronger and easier to tap, requires less support and provides greater flow area compared with pipes made from other materials like PVC, concrete, polyethylene or steel. Ductile Iron Pipe is the most widely-used pipeline product in water supply and water drain/sewage projects.
