ERW - Electric Resistance Welded Pipes
We are one of the largest suppliers and manufacturers of ERW pipes in Mumbai, Maharashtra, India. Reliable Steel Distributor specializes in supply of ERW pipes to companies and contractors across India. ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24” OD. In the process of manufacturing ERW pipes, steel strips in designated sizes are pulled through a series of rollers and formed into a tube which is fused through a electric charge. ERW pipes are generally manufactured in size range of 3/8″ to 24″ and used for low/ medium pressure applications such as transportation of water and oil.
ERW pipes supplied by Reliable are suitable for welding, bending, flanging, and similar forming operations. We sell all our ERW steel pipe products with Original Mill Test Reports, which include details on mechanical testing such as tensile, bending, flattening, hydrostatic and nondestructive electric tests.
