The ERW steel pipe is also known as straight joint pipe. According to the wall density, the bonded tube is categorized into typical types and thick-walled types. We can offer items with personalized wall thickness according to customers’ particular requirement with a thickness deviation of no more than 0.25 mm.With sizes between 1/2 inch and 24 inch, our ERW steel pipes go through rigorous examinations and tests, so about make sure the welding quality, external size precision, ovality, cut lengths, pipe end quality, wall density tolerance, and packaging quality are all conforming to API5L, ASTMA53, GB/T9711.1, or GB/T3091 standards. Also, we can make the item according to the standard needed by customers.

Manufacturing Process of ERW steel pipe:

Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam. The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond. The longitudinal ERW seam does not require filler metal.


Packing: Plastic plugs in both ends, Hexagonal bundles of max. 2,000kg with several steel strips, Two tags on each bundle, Wrapped in waterproof paper, PVC sleeve, and sackcloth with several steel strips, Plastic caps.

Test: Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test, Hardness Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, NDT TEST ( ET TEST, RT TEST, UT TEST)
