Description
SYI can supply the Centrifugally Cast Ductile Iron Restrained Joint Socket and Spigot Pipe according to ISO 10804, ISO2531, EN545,EN598, from DN80 to DN2000, including K7, K8, K9, K10,K12, K14, C20, C25, C30, C40, C50, C64, C100, with the coating of Metallic Zinc (130-400g/m2), Zn-Al Alloy 85/15, Black Bitumen coating, Red/Blue Epoxy coating, Cement lining or PU (polyurethane) coating.

 

Centrifugally Cast Ductile Iron Pipe is a kind of pipe made from spherical graphite cast iron by centrifugal spinning process. The pipes, which can convey many fluid media such as water, oil and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public service utility.

Mechanical properties

Nominal Size DN	Minimum tensile strength, Rm Mpa	Minimum 0.2% proof stress, Rp0.2 Mpa	Minimum elongation after fracture,A %	Hardness HB
80-1000	≥420	≥300	≥10	≤230
1100-2600			≥7
Note: 1. By agreement between manufacture and purchaser, the 0.2% proof stress (Rp0.2) may be measured. It shall be not less than: · 270 MPa when A≥12% for DN 40 to DN 1000 or A≥10% for DN >1000; · 300 MPa in other cases. 2. DN 40 to DN 1000, the minimum elongation after fracture shall be 7% for thickness classes over K12.
