1. precision hydraulic steel pipe precision hydraulic steel pipe is a kind of steel pipe specially used in hydraulic transmission system, which has the characteristics of high precision, high strength and high pressure resistance. Usually, high-quality carbon structural steel or alloy structural steel is used as raw material, and it is made by cold drawing, cold rolling, heat treatment and other processing procedures. Precision hydraulic steel pipes are mainly used to manufacture hydraulic components such as hydraulic cylinders, hydraulic valves and hydraulic pumps, as well as various high-pressure oil circuits and pipeline systems.
2.45# bright precision tube? 45# bright precision pipe is a kind of bright seamless steel pipe made of 45# steel, which has the characteristics of high precision, high smoothness and high strength. It is made by smelting, rolling, heat treatment and other processing procedures. 45# bright precision tube is mainly used to manufacture various mechanical parts, such as transmission shaft, connecting rod, bolt and nut. Its surface finish is high, with good corrosion resistance and appearance quality.
3.45# Precision Drawpipe 45# Precision Drawpipe is a precision seamless steel pipe made of 45# steel, which has the characteristics of high precision, high strength and high pressure resistance. It is made by smelting, rolling, heat treatment and other processing procedures. 45# precision drawing precision tube is mainly used to manufacture high-precision and high-strength parts, such as transmission shaft, connecting rod, bolt and nut. Its dimensional accuracy and mechanical properties are superior to those of ordinary seamless steel pipes.
4. Cold rolling treatment? Cold rolling treatment is the process of manufacturing or treating steel pipes. It carries out cold processing on the hot-rolled steel pipe through multiple procedures to obtain the steel pipe with the required size and performance. These processes include pickling, cold rolling, annealing and straightening. After cold rolling, the dimensional accuracy and mechanical properties of steel pipe are improved, and the surface smoothness is also improved. Cold rolling treatment is mainly used to manufacture various types of high-precision seamless steel pipes, such as steel pipes for fluid transportation and structural steel pipes. To sum up, precision hydraulic steel pipe, 45# bright precision pipe, 45# precision drawing pipe and cold rolling treatment are all concepts related to steel pipe manufacturing or treatment, but there are some differences between them. Precision hydraulic steel pipe is mainly used in hydraulic transmission system, 45# bright precision pipe and 45# precision drawing precision pipe are mainly used to manufacture mechanical parts, and cold rolling treatment is a process to manufacture or treat steel pipe. These concepts have different characteristics and requirements in practical application, and need to be selected and used according to specific needs and use occasions.
