Zinc Spraying Restrained Joint Ductile Iron Pipe K9 Class Cement Lining
Restrained joint ductile iron pipe overview:
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.
The diametral deflection, in percent, is one hundred times the vertical pipe deflection, in millimetres, divided by the initial pipe external diameter, DE, in millimetres. The values of allowable diametral deflection given apply to cement-lined C20, C25, C30, C40, C50, C64 and C100 pipes; they provide joint integrity as well as safety against overstressing of the pipe wall and excessive cracking of the lining. The maximum allowable deflection of cement-mortar-lined pipe is 4 %. National standards and manufacturers’ handbooks may introduce more stringent limitations, such as 3 %. The maximum allowable deflection for other types of linings can be calculated in accordance with ISO 10803, The manufacturer controls the quality of his products during their manufacture by a system of process control in order to comply with the technical requirements of this International Standard.It is recommended that the manufacturer’s quality system conform to ISO 9001, If certification to ISO 9001 is involved, it is recommended that the certification body be accredited to the relevant International Standard, as applicable.
Specifications:
1) The standard of pipe: ISO 2531, EN545 , EN598.

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.
Our advantages:
There are lots of qualified managers and technicians, and a well-trained team of after-sales service, which provides all services of manufacture, package, transportation and installation. We are looking forward to cooperating with friends from abroad and home creating a brighter future.
