WHAT ARE ERW MS STEEL TUBES?

ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured up to 24” OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through an electric charge.

Formed with the help of a specific type of welding process, it is made with great care. It involves the spot as well as seam welding. These two welding processes altogether quickens up the formation of ERW MS Precision Tubes. With the help of these welding processes, one can manufacture round, rectangular and square shapes of these tubes.

Common sizes for ERW Steel Pipe range from 2 3/8 inch OD to 24 inch OD in a variety of lengths to over 100 feet. Surface finishes are available in bare and coated formats and processing can be handled on site to customer specifications.

The ERW MS precision tubes manufacturer in the market focuses more on the quality and the customized shapes as per the requirements. It is mainly used for low/ medium pressure applications such as transportation of water/oil; they are also used for various types of engineering purposes, fencing, scaffolding etc.

COLD DRAWN WELDED TUBES

Precision tubes according to EN10305-2 are manufactured in a cold forming process for stretch-reduced or HF-welded hollow sections (shell). Welded drawn tubes are used primarily in the automotive industry, for instance as prop shafts, rubber/metal parts, drive shafts or cam shafts.

The application options for welded precision steel tubes according to EN 10305-2 are determined by specific technical characteristics, such as

• high level of dimensional accuracy for the internal and external diameter
• restricted tolerances for wall thickness
• process-related smooth surfaces
• good concentricity
• improved resistance values through cold forming
• freely selectable dimensions
