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.

Sourcing of Ductile Iron Pipes from Truform Europe

As a British and pan-European wholesaler, supplier and distributor of ductile iron pipes, our goal is to wholesale the ductile iron pipes manufactured in India and to provide our customers with preferential prices so that they are an alternative to other manufacturers and become our customers’ best choice.

Our specialty is the production of ductile iron pipes, mainly flanged ductile iron and puddle pipes. If you are interested in socket & spigot pipes, you must contact us as they are made to order.

Truform Europe is the wholesaler of ductile iron pipes for the customers, providing a direct business partnership and sourcing from Truform India.

Thanks to our presence in London, we are able to reach every customer in Europe, supplying him with world-class ductile iron pipes straight from the Indian production plant of Truform. At the same time, we provide constant support to our European clients without having to contact Truform India.

The cost and hassle of entire operation in transporting DI Pipes from Truform India to UK / Europe is included free for our clients. Not limiting to this, we also do all due-diligence on quality as well as after sales care for complete customer satisfaction. To facilitate ease of business we are here to help you as a partner.

To sum up, the wholesale purchase of ductile iron pipes via Truform Europe, provides our customers with measurable price benefits. When buying from us, remember that ordering a large number of products reduces shipping costs, which takes place by sea. Price preference is also affected by the amount of import duty rate on ductile iron pipes to Great Britain and Europe from third countries, which makes imports from India as cost effective.

    1. Application where pipelines are disengaged / dismantled for cleaning such as in water treatment plants for water, Effluent, Sewage and pump houses.
    2. Temporary installations where pipelines are transferred from one location to other requires Flange DI Pipes such as temporary pipelines for De-Watering mines or in heavily inundated areas
  3. Over Ground and & Exposed Installation: Ductile Iron Pipes are most suitable for over ground pipelines such as portions of Pipelines on Pillars / Pedestals for Rivers / Canal or Road crossing and bridges.
  4. Fire Fighting Systems
  5. For Laying in Hilly Areas / Slopes even exceeding the Angle of Repose.

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.
