Our seamless steel pipes are widely applied in petroleum drilling tools, hydraulic oil cylinder engineering machineries, boilers, mechanical industries, bearing tubes, automobiles, conveyance pipes for petroleum and natural gas, etc.

All of our products are fully inspected by following standards like API, ASME, DIN, EN, and customer requirements. We have a well-equipped laboratory that includes metallographic microscopic, microscopes (both microscope and macroscope), impact testing devices, spectrometers (fixed and portable), tensile testing machine, hardness tester, etc.

We have both UT and ET online inspection devices to ensure a 100% non-destructive test to inspect surface defects and the wall thickness difference on the whole length, which guarantee the product quality.
