Tubing is used to extract oil or natural gas from oil wells. The casing is used as the wellbore for oil and gas wells.

It can produce various steel grade oil casings. The products are successfully supplied to users such as PetroChina and Sinopec, and exported to Indonesia, Thailand, Egypt, Venezuela, Russia, Türkiye and other countries. In recent years, relying on the rare earth resource advantages of Baogang Baiyun Ebo Mine, we have independently developed and produced a series of oil well pipes for heavy oil thermal recovery wells, high anti extrusion oil well pipes, anti hydrogen sulfide corrosion oil well pipes, and anti CO2 corrosion oil well pipes. The products have been successfully applied in major oil fields in China. We have developed special buckle products with independent intellectual property rights, and have successfully developed various types of special buckles such as BT-1, BT-2, and BT-3.
