Production Description:

Ductile cast Iron Pipes with Push on Joint, K9

Ductile cast iron pipe conforms to ISO2531-1998 and EN545:2002, including the rubber ring in according to ISO4633, the coating of the pipe is the internally cement mortar lining and externally rich zinc paint and bituminous paint. The zinc spraying conforms to ISO8179, the minimum zinc spraying per square meter is 130g, and the thickness of bitumen paint is not below70 μm. And the cement mortar lining is in compliance with ISO4179, the thickness of which is as followed list.
