Large Diameter Pipes

Large Diameter Pipes
Stainless Steel Pipe (ERW) 10" NB to 24" NB. in schedule 5, Schedule 10, Schedule 20, Schedule 40 and also Special wall thickness is formed on 800 M.T. Press Brakes Hydraulic Press in length up to 6.0 to 7.0 meters. This section produces S.S. Pipes (welded) as per ASTM A - 358 by TIG welding and a filler material is used. The large diameter pipe is then sized & straightened to meet ovality and dimensional requirements of the applicable specifications. Testing, according to specifications, is then performed by either X-ray or Hydrostatic method. Final marking to size, grade & specifications is done prior to final visual inspection before dispatch.

 

Chemical, Physical and Hydrostatic Testing is done regularly since input raw materials are taken into the factory and during processing till dispatching of finished product.

Polishing

Polishing
The excellent properties of Stainless Steel Tubes and Pipes, including their high aesthetic & hygienic value, low maintenance and high durability, has led to an increased demand for polished tubes and pipes in architecture, general engineering, dairy & food-processing sectors, among others. To meet such demands for high-quality externally polished tubes and pipes, Dev Metal is equipped with a state-of-the-art polishing machine. Ranges of finish from 120 grit to mirror finish are made as per customers’ requirement.

Straightening

Straightening
After the annealing operation, the tubes are straightened with a straightening machine. In addition to giving a high degree of straightness, the tubes are also rounded up during the operation.

Annealing

Annealing
Annealing, or heat treatment, of the tube is carried out in fully automated conveyor. It consists of heating the tubes to a specified temperature and immediate quenching in circulating water thereafter.

Welded Pipes & Tubes

Welded Pipes & Tubes
Cold rolled Stainless Steel strips are welded into tubes in the state of the art tube mills under fully automated precision process.

The manufacturing of pipes begins with slitting of strips of required width based on the diameter of the tubes to be formed. Stainless steel slit strips are passed through a series of rollers and tubes are formed automatically on different stands with rolls and welded on fully automated process of TIG welding without the addition of filler metal. The welding head line is polished continuously with the help of automatic bead polishing machine to produce a perfect bore. The tubes are then passed through a series of sizing rolls to ensure joviality and tolerances. Tubes are then cut to length, Cold-drawn, Solution Annealed, Straightened, Pickled, Passivated and Polished before other Destructive and Non­destructive Testing & Dispatch. The systematic chain-type process has been approved and granted certification of maintaining International standard 1SO 9001:2008 & ISO 14001:2004.
