Drawn over Mandrel (DOM)/ Cold Drawn Electric Welded (CDW)

At MEIPL, we produce CEW/ DOM tubes using high-grade steel (removed high precise produce – need to confirm) that seeks application in products like Bobbin, Hydraulic cylinder, High-pressure applications as in Boilers for Power & Energy, and Front Fork for Auto Industry. With an installed capacity of 3000 MT/Month, we utilize 7 Draw Benches & 42 Pilger machines covering the range from 9 mm to 120 mm of OD within the thickness band ranging from 1 mm to 8.5 mm, MEIPL assures delivery of the high-quality product.

Also, with immense pleasure, we convey that, MEIPL is a first-class company in the precision welded steel tube industry to implement Cold Pilger technology for manufacturing DOM tubes.

This benefits of utilizing CEW/DOM tubes are: 

  • Enhanced mechanical properties of the product
  • Exceptional surface finish
  • Conformance to close dimensional tolerances
  • Substantial reduction factor in saving energy, labor costs, and high yield.
