Manufacturing


Raw Material & Inspection  :  Raw-Material is from reputed suppliers from India and abroad of National & International Standard along with relevant test certificates. In-house inspection is done as per supplier test certificate to quality check, cross-verify and confirm technical Specification, Standard, Label, Dimensions of Hot / Cold finished materials. Recorded OK material is used for manufacturing process.

Seamless Pipes, Tubes & U-Tubes


We have two types of Cold-drawing Process

Pilgering

  • Pilgering process using full link die and tapper mandrel.
  • Cold Pilgering are longitudinal cold rolling process that reduces the cross-section (diameter and wall thickness) by 90% of metal tube in one process step and small forming steps.
  • By cold Pilgering process surface finish achieved better than cold drawing finish (Less than 0.4 micron) and improved micro-structure grain size.
  • Our range is OD 12 to 73mm and wall thickness 0.8 to 4mm

Cold Drawing

  • In cold drawing process raw material tubes are Coated & Lubricated or Applied with some special chemicals or lubricant oil.
  • In cold drawing process the tubes are pulled through tungsten carbide die through buoyant/fixed plugs inside. The tubes resulting in reduced tube diameter and wall thickness corresponding increase in tube length
  • In cold drawing process the tubes are pulled through tungsten carbide die through buoyant/fixed plugs inside. The tubes resulting in reduced tube diameter and wall thickness corresponding increase in tube length

Welded Pipes, Tubes & U-Tubes


Welded Pipes, Tubes & U-Tubes

Welded Pipes & Tubes

  • Welded Tubes / Pipes is a Tube Mill operation
  • Cold/Hot Rolled Coils are slit in to strips for the required width as per the diameter of tube to be formed.
  • The strips are then feed to the de-coiler from where it passes through series of press rollers, forming rollers & gradually formed in to a tubular shape and welded by tungsten-inert-gas (TIG).
  • Welding Process- Highly precision with completely automated process where the edge of strips are fused together under pressure & protected atmosphere of argon gas through a non consumable tungsten electrode without adding any filler metal
  • Our range is OD 12 to 73mm and wall thickness 0.8 to 4mm

Large Diameter Welded Pipes

  • Manufactured through/on 800MT Hydraulic Press, by TIG welding using filler Metal in all Passes. The large diameter pipe are then sized & straightened to meet ovality and dimensional requirements of the applicable specifications.
  • This unit produces welded pipes as per ASTM A – 358. Testing in according to specification, is then passed by X-ray, Ultrasonic, DP Testing and Hydrostatic Testing
  • Our range is 6" NB to 80" NB in Sch 5 / 10 / 20 / 40 and also special wall thickness, in length upto 6.0 to 7.0 meters.
  • Chemical, Physical and Hydrostatic Testing are done regularly right from raw material stage, in process till despatching of finished product. Final marking to size, grade & specifications is done prior to final visual inspection before despatch.
