We make API 5CT C90 Casing Tubing according to the SY/T6194-96 standard, it is open as short string sort and long string sort gave their couplings.

T91/P91 steel pipes are widely used in superheaters and reheaters of subcritical and supercritical boilers, as well as high-temperature headers and steam pipes with lower wall temperatures.

SUS630 also known as 17-4PH, is a high-strength, corrosion-resistant martensitic stainless steel alloy.

API 5L X56 PSL2 carbon steel pipe plays a key role in the oil and gas transportation process. It is used as key components such as oil pipes and casings and is subjected to harsh conditions such as high pressure and high temperature.
