ERW/CDW Precision Tubes

Pennar Industries offers product categories like ERW, CDW, Air Pre-Heater, Boiler, Corten Steel, Galvanized & Stainless Steel Tubes. The tube production capacity 60,000MT/Annum. (ERW – 5000 MT/month, CDW – 1800 MT/Month and Stainless Steel tube – 500 MT/month).

We produce Low carbon, Medium carbon, High Strength Low Alloy (HSLA) tubes and Stainless Steel for Automobile Industries, Bi-Cycle Industries, General Engineering, Textile Industries, Boiler/Air Preheater Industries & other Engineering trade segments.

The raw material required for tube making is a steel strip which undergoes various stages of processing. HR or CR strips in the form of coil is procured from indigenous steel makers and import sources and are used in the manufacture of a tube depending on the application.

Manufacturing begins in a separate preparatory section where the strip is slit into required width depending on the diameter of the tube & subjected to acid pickling process to remove all rust and scale in strip pickling plants.

Separate in-house cold rolling mills also cater to raw material requirements for closer dimensional tolerances and bright surface finish of tubes.

We manufacture different shapes like Round, Square, Rectangle, Hexagonal and profile tube as per customer requirements.
