Company profile
Liaocheng Xinruyi Trading Co., Ltd built in year 2017 with registered capital of 3000, 000RMB, and we have been in the steel products industries for more than 10years. The company is located in Liaocheng City, next to capital of Shandong Province, and it enjoy good transportation environment of 3 hours to nearest port and 1 hour reaching the airport. 

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.

Commodity hot-sales features
Cold Rolling Production Process Method Bright Precision Seamless Steel Pipes is one of our hot-sale commodities, which is newly developed these years. Due to cold rolling products' features like good precision size and bright surface, it is getting more and more attention and acception from cleints. We are giving its magnificent advantages as follows:

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.

From the table we can see cold rolling precision steel pipes have a lot of advantages than the common hot rolled steel pipes.
