Downhole Tools


Xinxing Steel As a leading oilfield downhole tools supplier, we specialize in delivering high-performance, precision-engineered solutions for drilling, completion, and workover operations in conventional and extreme environments. Our product portfolio includes standard carbon steel profiles (angles, beams, channels) and specialty grades (austenitic stainless steels, duplex steels, titanium alloys, and high-temperature alloys), adhering to API Spec 7-1, ISO 9001, and NACE MR0175 standards. Equipped with state-of-the-art CNC machining centers and certified by API Q1, CE/PED 2014/68/EU, we ensure materials meet stringent requirements for high-pressure, corrosive, and high-temperature applications in oil & gas, geothermal, and subsea systems.
