Product Description

High Strength Restrained Joint Ductile Iron Pipe DN80mm - DN2600mm Diameter


Self-Restrained joint ductile iron pipe:

Ductile iron pipeline systems, including pipes, fittings, accessories and joints, consist of various materials.When used for conveying water intended for human consumption, the materials in contact with the water shall meet the relevant requirements of the national standards or regulations in the country of use with respect to effect on water quality. When used under the conditions for which they are designed, in permanent or in temporary contact with water intended for human consumption, ductile iron pipes, fittings and their joints shall not have detrimental effects on the properties of that water for its intended use. 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.

Technique specification:

First, install the locks on the connection section of two pipes, screw the short bolt, then push the locks to the spigot end and socket end separately,adjust the bolt hole place of long bolt on the spigot end and socket end, make sure the holes on two sides are concentric, screw the long bolt, fasten the bolt on socket end first, then the spigot end, at last fasten all the short bolts.



1) The standard of pipe: ISO 2531, EN545 , EN598.

2) Pipe class: K9, C40, C30, C25, etc.

3) High strength, lighter than gray iron, good corrosion resistance, no furring, small flow resistance, easy fixing, long life time

4) Checked by automatic inspection equipment.


Safety factors for ductile iron pipes:

Design criteria Safety factor Mechanical property
PFA 3 Minimum ultimate tensile strength of 420 MPa
PMA 2.5 Minimum ultimate tensile strength of 420 MPa
External loads 1.5 Yield bending strength of 500 MPa



Packing: bundled with steel belts or in bulk

Shipment: in bulk or container



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.
