Indian Manufacturer of Ductile Iron Pipes

Truform manufactures Flanged Ductile Iron pipes and Flanged Ductile Iron Puddle Pipes with Socket and Spigot.

Flanged ductile iron pipe is Truform’s specialty. These pipes can withstand high tension and compression with very limited degree of shear and bending. These pipes are produced in several versions in terms of size and pressure rating.

Our production plant is located in central India and has an excellent infrastructure connection via Indian rail, road infrastructure and airport. As a wholesaler and supplier, we are able to supply customers with products in accordance with current production or produce them, on request, in accordance with the indicated specification.

Truform’s fabricates these flanged ductile Iron pipes using two types of flanging technology as explained below.

A) By way of screwing of DI pipe – threaded flange DI Pipe

Crediting to Truform’s knowledge and experience in screw flange technology, the flanges can be tightened or bolted on both sides of ductile iron pipes. In this way, the pipes can easily be joined to act in a similar way to socket and spigot pipes. 

B) By way of Welding of DI Pipe – welded flange DI Pipe

Using Hot Shrink Fit technology, Truform also able to produce welded Flange ductile iron pipes. In this case flanges are raised by welding on either side of ductile iron spun Pipes. Such technology allows to meet specific application needs.

NOTES

1. The method of screwing and the exact form of thread are as per standard manufacturing process on the basis that flanges are not removed after screwing on the barrels of the pipes.
2. Dimension ‘S’ is for guidance only.
3. Unless otherwise specified flanges are made of ductile iron.
