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)
Flanged Pipe Type Diameter Range and Lengths  PN Ratings
Welded Flanged Pipes From 80DN to 1000DN lengths up to 5.0 m. PN 10, PN 16, PN 25, PN 40
Screwed Flanged Pipes From 80DN to 300DN diameter, in lengths up to 5.0 m. PN 10, PN 16
Cast Flanged Pipes From 80DN to 200DN up to 700mm length and 250DN to 700DN up to 1.2 m length 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.
