ERW Steel pipe

Description

ERW pipes means Electric Resistance Welded Pipes. ERW steel pipes and tubes are used. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc.

ERW steel pipes and tube are available in various qualities, wall thicknesses, and diameters of the finished pipes.
Based on the customers requirements we can manufacture erw pipes and tubes of different size and shape. We have a very large production capacity of erw pipes and tubes.

ERW steel pipe
ERW steel pipe is one of the main pipe structural material in construction and liquid transfer steel material. It is properly used in bridge building, underground transfer assemble structure ,agriculture, chemical liquid transfer, oil and gas transfer and so on, It will be manufactured by electricity resistance welding. The outside surface can be treated by galvanizing, painting, PE coating, PP coating, HDPE coating and so on, The main advantage is welding beam can be very smooth. It is very good to do the transfer and liquid job.  Normal usage validity time will be around 50-80 years. Standard can be API, ASTM, JIS etc.

ERW pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. ERW pipe is available in lengths from single random to 120 feet depending on mill capability. ERW pipe is available with square ends or beveled for welding, threaded and coupled and victaulic grooved. Surface finish are available in black or bare, or with protective coatings.
For pipes or tubes size 4 inch (10.2mm) OD and below, strip is fed into a set of forming rolls which consists of horizontal and vertical rollers so placed as to gradually from the flat strip in to a tube which is then allowed to pass the welding electrodes. The electrodes are copper disks connected to the secondary of a revolving transformer assembly.
