Cement Mortar Lined Ductile Iron Pipe Centrifugal Cast Anti Corrosion ISO 8179
EN598 high alumina cement mortar lined Ductile Iron Pipe overview:
Dutile iron pipe under EN598 standard shall be delivered with an external coating of zinc with finishing layer and an internal lining of high alumina cement mortar,This shall not preclude special coating arrangements for products which deviate from the requirements for specific design reasons. Pipes for sewers and drains shall be identified externally by one of the following colours: brown, red or grey. This is to allow easy identification of installed sewers and drains. Pipes specifically intended for rain water or surface water sewers (separate systems) may be identified by a different colour other than those used for potable water pipes.The iron thickness of fittings used for pressure sewers shall be in accordance with EN 545, The iron thickness of fittings used for gravity sewers shall be equal to or higher than those of pipes of the same DN.
Specifications:
The limit deviations on lengths of the socket and spigot pipes shall be within - 30 mm, + 70 mm. The limit deviations on lengths of flanged pipes and of fittings shall be in accordance with EN 545.
The limit deviations on lengths of fittings used for gravity sewers shall be made available by the manufacturer.
Pipes shall be straight, with a maximum deviation of 0,125 % of their length.
The tensile strength shall be tested in accordance with 6.3.

By agreement between manufacturer and purchaser, the 0,2 % proof stress (Rp0,2) may be measured. It shall be not less than:
¾ 270 MPa when A ³ 12 % for DN 80 to DN 1000 or A ³10 % for DN > 1000;
¾ 300 MPa in other cases.

Packing: bundled with steel belts or in bulk
Shipment: in bulk or container.
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.
