Carbon Steel Din2391c St35 St3 4 St524 Steel Precision Seamless Pipe

Features 1. Smaller outside diameter. 2. High precision can do small batch production. 3. Cold-drawn products have high precision and good surface quality. 4. The cross area of steel pipe is more complex. 5. The performance of steel pipe is superior, and the metal is dense. 3. Cold-drawn products have high precision and good surface quality. 4. The cross area of steel pipe is more complex. 5. The performance of steel pipe is superior, and the metal is dense.Precision steel tube is a kind of high precision steel tube material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel tubes have no oxide layer, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no cracks, they are mainly used for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders, can be seamless tubes, but also welded tubes. Precision steel pipe with high dimensional precision, inner and outer surface smoothness, after heat treatment, there is no oxide film on the inner and outer surface of the steel pipe, the steel pipe flaring, flattening without crack, cold bending without deformation, and can withstand high pressure, can make various complicated deformation and mechanical deep processing.

Precision steel tubes are used in automobile, motorcycle, electric car, petrochemical, electric power, ships, aerospace, bearings, pneumatic components, middle and low pressure boiler seamless steel tubes and other categories, can also be used in steel bars, bearings, hydraulic, mechanical processing and other fields! The production process of precision steel pipe is the same as that of ordinary seamless pipe, which is more than the process of pickling and cold rolling. Precision steel tube process billet -- inspection -- peeling -- inspection -- heating -- perforation -- pickling passivation -- grinding -- lubrication -- air drying -- cold rolling -- oiling -- cutting -- inspection -- identification -- finished product packaging steel tube difference 1, seamless steel tube is the main feature of no welding joint, can withstand greater pressure. The product may be very rough cast or cold - drawn. 2. Precision steel pipe is a product emerging in recent years, mainly with strict tolerance and roughness of inner hole and outer wall size.

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.

The group company mainly produces and sells a series of steel products such as steel pipe, steel coil, steel plate, copper pipe, copper plate, copper strip, aluminum pipe, aluminum plate, galvanized steel pipe, galvanized coil, galvanized plate and so on.The group company has established five platforms, including three production plants and two processing plants. At present, it is still expanding its production line, basically forming a development model of integration of production, processing and sales.

Our annual production capacity of various specifications is about 1 million metric tons. In addition to being a supplier of our series of products, the group company is also committed to expanding its commitment to customers by strengthening services and adding new facilities. A dedicated team is responsible for providing technical support, recommending the correct use of steel, and assisting customers to give full play to their products.

Over the years, we have opened up new markets in Africa, Southeast Asia, the Middle East and America. Our best service and excellent quality have led long-term partners in many countries and established continuous business relations with all customers. Our principle is "service first, sales second". Most of the time, we have comprehensive inspection and procurement to control the quality of finished products. We will have a professional inspection team to test each delivery of products.

Since its establishment, in line with the mission of "contributing high-quality products and services to the world" and the core values of "customer first, excellence, coexistence and win-win", we ensure that we can deeply cooperate with all our friends in the field of iron and steel, and win more affirmation and praise from the market and customers with its high-quality products, perfect product team and thoughtful service, I believe tomorrow will be better!
