Cold-rolled and cold-drawn precision steel pipes of various sizes and materials can be customized.Precision tube is a high-precision, high-brightness seamless steel tube produced through cold drawing or cold rolling processes. Its inner and outer diameter dimensions can be accurate to within 0.2mm. It ensures bending and torsional strength while being light in weight, so it is widely used in manufacturing precision mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, bearings, etc.
Special-shaped seamless steel pipes are seamless steel pipes with special cross-sectional shapes. Unlike traditional round seamless steel pipes, their cross-sectional shapes can be designed into various non-circular shapes such as ellipse, rectangle, and hexagon to meet the specific requirements of different engineering fields.
Precision steel pipe is a high-precision cold-drawn seamless steel pipe with the characteristics of high accuracy in inner and outer diameter dimensions, wall thickness, good surface finish, smooth inner and outer surfaces, and no impact burrs. Precision steel pipes are usually made of carbon steel, alloy steel, stainless steel and other materials, and are widely used in manufacturing machines, automobiles, aerospace, health equipment and other fields.
Aerospace manufacturing: Due to the characteristics of high precision, thermal strength, corrosion resistance and high wear resistance, precision steel pipes are widely used in engines, leading edge flaps, missile control systems and other parts in the aerospace industry.
Instrument and medical equipment manufacturing: Precision steel pipes are strong, corrosion-resistant and pressure-resistant. They are widely used in high-precision instrument manufacturing, pharmaceutical pipelines, medical equipment and other fields.
