Liaocheng Jinshan Steel Pipe Co., Ltd. is a large-scale enterprise specialized in production of cold-rolled precision seamless steel tubes. The company has modern standard plant, 23 advanced precision cold-rolling pipe mill production lines and complete physicochemical equipment, realizing an annual productivity of 100, 000 tons of cold-rolled precision seamless steel tubes.
Product Specification Range: φ18-φ121×2-25mm
Materials: High-quality carbon steel, low alloy steel, bearing steel, etc.
Products produced by the company mainly include: cold-rolled precision steel pipe special for gas springs, cold-rolled precision steel pipe special for automobile shock absorbers, cold-rolled precision steel pipe special for motor shock absorbers, precision steel pipe special for motor shells, precision inner-diameter seamless steel tube for hydraulic and pneumatic cylinder barrels, etc.
Outstanding Features:
1. The cold-rolled precision steel pipe has high tolerance dimension precision and the product precision is controlled to be ±0.05mm; high finish; no oxide layer on the internal surface and the external surface, good internal wall cleanness.
2. The cold-rolled precision steel pipe has excellent comprehensive performance, is able to bear high pressure, does not crack or cockle when it is cold-bended or pressed flat or its mouth is expanded, and can be subjected to all kinds of complex deformation and mechanical processing treatment.
3. The popularization and application of precision seamless pipe can save steel, improve processing efficiency, reduce processing procedure and equipment investment, save cost and greatly save the time of mechanical processing and improve production capacity and material use ratio. At the same time, it also can improve product quality and reduce cost.
Always in line with the enterprise philosophy of “Develop by Technology, Survive by Quality”, the company wins trust of customers by high-quality products. Facing the national market, the company sincerely looks forward to making wide and close cooperation with national customers for common development.
