High Precision API-certified Steel Pipe

High dimensional accuracyPrecision steel tubes are manufactured by cold rolling or cold drawing processes, with relatively high dimensional accuracy, usually achieving a tolerance of ±0.05mm. High-precision dimensional control ensures the stability of the pipe during assembly and use, making it suitable for use in mechanical equipment that requires precise fit.

Smooth inner and outer surfacesThe inner and outer surfaces of precision steel tubes are smooth, reducing friction loss and improving the efficiency of fluid or gas flow inside the tubes. They are suitable for application scenarios such as hydraulic systems and pneumatic systems that require smooth inner walls.

Wear resistance and corrosion resistanceAfter surface treatment, precision steel tubes have excellent wear resistance and corrosion resistance, and can maintain a long service life in harsh environments. Common surface treatment methods include galvanizing, phosphating and oxidation treatment to enhance its durability in damp, acidic and alkaline environments.

Excellent mechanical propertiesPrecision steel tubes are typically made of high-quality carbon steel or low alloy steel. Through heat treatment (such as quenching and tempering), their tensile strength, yield strength and toughness are enhanced, enabling them to withstand high working pressure and mechanical stress, and making them suitable for use in high-intensity environments.

Q: What is the difference between precision steel pipe and ordinary steel pipe?

A: Precision steel pipe has high dimensional accuracy, smooth internal and external surfaces, no oxide layer, and more stable mechanical properties, which is suitable for occasions with high precision requirements. The accuracy and surface quality of ordinary steel pipes are low, and they are mainly used for general industrial purposes.

A:Precision steel pipes are usually produced by cold rolling or cold drawing processes. Cold-rolled steel pipe by rolling forming, higher dimensional accuracy; The cold-drawn steel pipe has higher mechanical properties by stretch forming.
