Tight Dimension Tolerance ERW Welded Steel Pipe For Precise Structural Matching

Product Description

ERW (Electric Resistance Welded) steel pipe is manufactured by rolling steel coil into round form and welding the seam without added filler metal. It offers consistent dimensions, smooth surface and cost-effective performance compared to seamless pipe. Available in black, galvanized or black-painted finish, our welded pipes meet ASTM A53, EN 10219 and GB/T 3091 standards for water, gas, oil, piling, scaffolding and structural applications worldwide.

· Piling, bridge and port foundation works

· Scaffolding, fences, handrails and greenhouse frames

· Structural tube, mechanical parts and furniture construction

Advantages & Features

1. Cost-effective – Lower price than seamless pipe, ideal for low/medium pressure applications.

2. Tight dimensional tolerance – Uniform OD and WT ensure easy threading, welding and fitting.

3. Hydraulic tested – Each batch undergoes hydrostatic test as per ASTM A53 / GB/T 3091.

4. Surface options – Black, galvanized, painted and varnished for indoor or outdoor use.

Usage & Notes

· Store indoors in dry condition; seal ends to prevent moisture ingress.

· For water/gas service, pressure test must follow project specification before installation.

· Galvanized pipes require special welding procedures (pre-cleaning of zinc layer).

· Beveled ends are recommended for welding; threaded ends come with plastic protectors.
