Ductile Iron Pipes - Flanged Joints

Electrosteel manufactures Flanged Pipes using all the three methods

    • Welded Flanged Pipes
    • Screwed Flanged Pipes
    • Integrally Cast Flanged Pipes (short lengths)
Type of Pipe Dia Range and Lengths  PN Ratings
Welded Flanged Pipes
Flanges are welded on either side of a Class K9 Barrel or equivalent C Class From 80 to 1200 mm diameter and length up to 5.4 mtr. PN 10, PN 16
PN 25, PN 40
Screwed Flanged Pipes
Flanges are screwed-fit on either side of a Class K9 Barrel or equivalent C Class From 80 to 400 mm diameter and length up to 5.4 mtr. PN 10, PN 16
"As Cast" Flanged Pipes
Flanged Pipes are cast as a single unit using advanced Lost Foam method. From 80 to 1200 mm diameter. PN 10, PN 16
PN 25, PN 40

Points to Remember

    • Buried installation of flanged pipe is not recommended.
    • Flanged joint being a rigid joint, perfect alignment of the flange faces during jointing and bolt tightening is absolutely vital.
    • Use of duck foot bend at bottom of vertical flange pipe line is necessary.
    • For high pressure application, flanged pipeline needs thrust block or support at bends / tees.
