About Us

The seamless steel tube we produce are based on European En10305 standard, German DIN2391 standard, American ASTM A269 standard and Japanese JIS series. The company selects high-quality billet , and cooperates with our unique Cold drawn or Cold rolled steel pipe manufacturing and processing technology, which is made through strict quality control. Seamless steel pipe is characterized by high precision and good finish. The company adopts oxygen free bright heat treatment process, which produces no oxide layer on the inner and outer walls and has high surface finish. The process performance of the steel pipe fully meets the high-pressure requirements: no leakage in the high-pressure environment, no deformation in bending, flaring and flattening.
