Hydraulic Cylinder Steel Pipe
Using cold-drawn, high-strength carbon steel pipe for mechanical structures, the material undergoes factory tempering for uniform quality.
The inner diameter is precision-machined, and the surface roughness and tolerances meet international standards.
In addition to a sufficient inventory of standard sizes, Changjin also accepts custom orders for special specifications, materials, and lengths, ensuring the highest efficiency and quality in meeting customer needs.
