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, скеле, engineering, и т.н.. 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, газ, и масло.

1. Външен диаметър: Ф219-Φ660mm
2. Дебелина на стената: 6-22мм
3. Length: 3-12м
4. Марка стомана: Q345B, API X42 - X80, L245, L555,J55, От 80
5. Стандарт: SY/T5037-2000, GB/T9711.1-97, API SPEC 5L
6. Тест: hydro testing, ultrasonic detection, ultrasonic testing for pipe end,
visual and dimension inspection, weighing and measuring, и т.н..
7. Packaging:Standard export seaworthy packing (or according to your request)

Процес:
