ERW STEEL PIPES

ERW CARBON STEEL PIPES - Electric Resistance Welded Pipe

ERW Pipe stands for Electric Resistance Welded Pipe, featuring cost efficiency and a closer tolerance of wall thickness when compared with seamless steel pipe. It is widely used in fencing, scaffolding, engineering, etc. To ensure high precisions and quality of ERW Pipe, our SMC uses of high qualified materials, and have rigid quality control.

Usage: Used for low pressure liquid delivery, such as water, gas, and oil.

Specifications of ERW Pipe(Electric Resistance Welded Pipe):
1. Outside Diameter: Ф219-Φ660mm
2. Wall Thickness: 6-22mm
3. Length: 3-12m
4. Steel Grade: Q345B, API X42 - X80, L245, L555,J55, N80
5. Standard: SY/T5037-2000, GB/T9711.1-97, API Spec 5L
6. Test: hydro testing, ultrasonic detection, ultrasonic testing for pipe end,
visual and dimension inspection, weighing and measuring, etc.
7. Packaging:Standard export seaworthy packing (or according to your request)

Feature of ERW Pipe (Electric Resistance Welded Pipe);
1) Economy Benefit: ERW steel pipe is less expensive than seamless steel pipe.|
2) High Precision: ERW steel pipe has a closer tolerance of wall thickness whencompared with seamless steel pipe.
