304 316L 410 420 Cold Rolled 8K Mirror Polished Hairline Seamless Stainless Steel Pipe

Stainless steel pipe is a hollow strip of circular steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrument and other industrial pipeline and mechanical structure parts. In addition, in the same bending, torsional strength, light weight, so it is also widely used in manufacturing machinery parts and engineering structures. It is also commonly used as furniture and kitchenware.

According to the material, stainless steel pipe is divided into ordinary carbon steel pipe, high quality carbon structure steel pipe, alloy structure pipe, alloy steel pipe, bearing steel pipe, stainless steel pipe and bimetal composite pipe, coating and coating pipe to save precious metals and meet special requirements. There are many kinds of stainless steel tubes, different uses, different technical requirements, production methods are also different. The current production of steel pipe diameter range of 0.1-4500mm, wall thickness range of 0.01-250mm. In order to distinguish its characteristics, steel pipes are usually classified as follows.

Mode of production
Stainless steel pipe according to the production method is divided into seamless pipe and welded pipe two categories, seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawing pipe and extrusion pipe, cold drawing, cold rolling is the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.

The section shape
Stainless steel pipe can be divided into round pipe and special-shaped pipe according to the cross-section shape. Special-shaped tube has rectangular tube, lozenge tube, elliptic tube, hexagonal tube, eight direction tube and all sorts of section asymmetry tube to wait. Special-shaped tubes are widely used in various structural parts, tools and machinery parts. Compared with the round tube, the special-shaped tube generally has a larger moment of inertia and section modulus, has a larger bending, torsion resistance, can greatly reduce the weight of the structure, save steel.

Stainless steel pipe can be divided into equal section pipe and variable section pipe according to the longitudinal section shape. Variable section pipe has conical pipe, ladder pipe and periodic section pipe, etc.

Tube shape
Stainless steel pipe can be divided into light pipe and wire pipe according to the state of the pipe end (with threaded steel pipe). Turning wire pipe can be divided into ordinary turning wire pipe (water, gas and other low-pressure pipe, using ordinary cylindrical or conical pipe thread connection) and special thread pipe (oil, geological drilling pipe, for important turning wire pipe, using special thread connection), for some special pipe, in order to make up for the influence of thread on the pipe end strength, The pipe end is usually thickened (inside, outside or inside) before the wire is spun.

Use classification
It can be divided into oil well pipe (casing, tubing and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, petroleum cracking pipe) and ship pipe.

production
Stainless steel welded pipe production process:

Raw material - swatch - welding pipe - end - polishing - inspection (printing) - packaging - shipment (warehousing) (decoration welded pipe).

Raw material - article points - welding pipe, heat treatment, correct, straightening, fix the end, pickling, water pressure test, inspection (spurts India) - packaging - shipment (transport) (tube) for piping weld pipe industry.

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!
