Product Description
Company profile |
As it is well known to all, Liaocheng city is the biggest steel pipe base in North China, with this significant advantage on geography aspect, us company have developed into one modern international trading and exporting company. Our salesmen are trained to get the best and professional skills on doing export trading dealing with various kinds of issues in the trading, which is a base that our buyers can have good buying experience. Till now we can supply the good quality products consisting of and not limit to the following, steel pipes, bars, rock bolts, guardrail composite pipe, guardrail board, color coated steel coils, galvanized coils, steel balls, steel chains, steel plates and steel bearing. Besides we can provides processing procedures for the steel products, like anti-rust protecting, cutting and chamfer, coupling, heat treating, bending, galvanizing, polishing, beveling and so on.
With efforts of Xinruyi People we have the pleasure to serve the clients from more than 20 countries and areas, We earned good reputations from the clients without any claim. We finally become good friends and intimate partners with them.
Looking forward, we get good confidence that we will expand our business scales to more countries and areas, and serve more people in the world.

Main Advantages of cold rollong precision steel pipes:
A. High precision size and much smaller tolerance, this pipe is produced under cold rolling process method. The pipe OD and ID tolerance can be with -0.1/+0.1mm, and even through our 3-roller machine we can control the pipe OD and ID tolerance within -0.05/+0.05mm. There is no oxide skin layer on both inside and outside surfaces, degree of finish is very well.
B.High precision cold rolling seamless steel pipes have good comprehensive mechanical property. It can bear high pressure, cold bending, expanding, pressing flat without crack, and other complex size change and mechanical handling.
C.High precision cold rolling seamless steel pipes being used largely will help save the steel materials, promote the machining efficiency, reduce the expense and decrease processing time on large extent.
So this kind of pipes are widely as deformed bar connection, automobile components, mechanical engineering parts, hydraulic fittings, bearing, peneumatic components, oil cylinder, boiler equipment and so on.
We would love to give one table to compare the cold rolling precision steel pipes and common hot rolled steel pipes, supposing we need one finished round precision cylinder of finished size OD 55.19mm x ID 42.58mm x Length 1000mm. And we use these two kinds of pipes as the materials.
Comparing Table | cold rolling precision steel pipes | common hot rolled steel pipes |
Outside surface bright | Yes | No |
Without oxide skin layer | Yes | No |
Inside surface smooth | Yes | No |
Needing size | 55.29x42.48x1000 | 57x41 |
Tolerance allowed | -0.1/+0.1 for OD and ID (under 3 rollers -0.05/+0.05) | 1% for OD (-0.57/+0.57mm) |
