Description

Technical Field

[0001] This utility model relates to the field of steel pipes, and in particular to a lightweight, high-strength, irregularly shaped hydraulic steel pipe. Background Technology

[0002] Hydraulic steel pipes are core components in hydraulic systems for transmitting high-pressure fluids. They belong to the category of cold-drawn or cold-rolled precision seamless steel pipes and are widely used in hydraulic cylinders, pneumatic cylinders, engineering machinery, and precision automotive parts. Through cold drawing / cold rolling processes and treatments such as pickling and phosphating, this product features no oxide layer on either the inner or outer walls, high dimensional accuracy, and low surface roughness. It can withstand high pressure and resist deformation.

[0003] However, the structure of ordinary hydraulic steel pipes is simple, just a hollow steel pipe. When the steel pipe is used, the two ends need to be welded to connect the pipes to deform the structure, which reduces the strength of the steel pipe. Traditional hydraulic steel pipes also lack anti-corrosion and anti-oxidation precision treatment.

[0004] To solve the above problems, this utility model provides a lightweight, high-strength, irregularly shaped hydraulic steel pipe that allows both ends of the hydraulic steel pipe to have a quick-connect bending pipe shape. The structure is integrally formed and has lightweight and high-strength characteristics. The inner and outer walls of the hydraulic steel pipe body are provided with anti-oxidation and anti-corrosion layers, providing excellent protection performance. Utility Model Content
