Main Advantages of Commodity

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.

Insepction And Testing

 

Xinruyi Steel Group was built in year 2017 with registered capital of 30,000,000RMB, and we have been in the steel products industries for more than 10years. The group 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 XINRUYI STEEL GROUP. Till now we have two production plants for steel pipes and plate series production and processing, and three warehouses for steel products. Our yearly production scale can be reach to 500,000tons, and our warehouse stocks is yearly above 20,000tons. So that we can meet all kinds of demands from different countries clients. 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, pickling, plastic spraying, CNC machining, 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. Because we always believe quality of the commodity is the life of company, stability is the essence of quality. Also the integrity in business will help bring the long term business relationship, so it is the code that one company can develop and survive. 
Xinruyi Group is looking forward to the cooperation with you! We believe one time cooperation, friends forever!
(Xinruyi Steel Group Swear: we do not cheat any of our client, we only do business with good faith and honesty! Recent years especially in year 2021, lots of sellers of steels set up one international trading company, register Made-in-China VIP member, and make money by cheating clients.They are offering incredible low rate to attract clients and sending less weight goods to make money. )
(Xinruyi Steel Group Swear: Even if we do not get the order, we do not cheat even one client!)
