API Standard 219-273mm Diameter Erw Black Steel Pipe

Description

ERW straight seam welded pipe is generally used as wire bushing in the power industry. Performance characteristics: 100% ultrasonic testing of the base metal ensures the internal quality of the pipe body;

No unwinding - disc cutting process, base metal compaction pit, less scratches;There is basically no residual stress in finished pipe after stress relief.The welding seam is short, the probability of producing defects is small;

Can have the condition to transport moist acid natural gas;

After the diameter expansion, the steel pipe has a high geometric accuracy.

The welding is carried out in the horizontal position along the straight line after the forming is completed, so the staggered edge, slit and pipe diameter circumference are well controlled, and the welding quality is excellent.Our products have been used in various fields, such as aviation, aerospace, navigation, nuclear energy, chemical industry, electronic information, machinery manufacturing, petrochemical, automobile, instrumentation, communication, transportation, medical equipment and so on.
