The High Pressure Capillary Steel Oil Tubing undergoes acid pickling, cold rolling, and cold drawing, and adopts advanced high-temperature oxygen free heat treatment technology (NBK). The Capillary Steel Tubing has a bright and smooth surface, high precision, high smoothness, no oxide layer on the inner and outer walls, high precision on the inner and outer walls, excellent mechanical properties, and can withstand high pressure, cold bending without deformation, expansion, flattening, tensile strength and other requirements, achieving no cracking or cracking during cold bending of the steel pipe. Precision Capillary Steel Tubing is a seamless pipe made by precision cold drawing, which undergoes oxygen free tempering treatment to eliminate surface and internal stress, and then undergoes phosphating and rust prevention treatment.

There are no blockages in pneumatic, hydraulic, or oil circuits. The elongation and tensile strength are excellent, and the products have reached the international advanced level. High Pressure Capillary Steel Oil Tubing are regularly supplied to large and medium-sized enterprises such as Shanghai Volkswagen, FAW Volkswagen, and Dongfeng Chaochai.

It is Widely used in fields such as diesel engines, gasoline engines, automobiles, mechanical hydraulic transmissions, etc
