Stainless steel pipe

Stainless steel pipe is a kind of hollow long round steel, which is widely used in industrial transmission pipelines such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instruments and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture, kitchenware, etc. Stainless steel pipe is safe, reliable, hygienic, environmentally friendly, economical and applicable. The thin wall of the pipe and the successful development of new reliable, simple and convenient connection methods make it have more irreplaceable advantages than other pipes. Stainless steel has many ideal properties required by building materials, integrating performance, appearance and use characteristics. It can be said to be unique in metal, And its development continues. In order to make stainless steel more neutral in traditional applications, existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the most cost-effective materials selected by architects. It will be more and more used in engineering, and the use will be more and more popular, with a good prospect.

process:

Stainless steel seamless tube production process a. Round steel preparation; B. heating; C. Hot rolling perforation; D. cutting head; E. pickling. F. grinding; G. lubrication; H. Cold rolling; I. degreasing;J. Solution heat treatment; K. straightening; L. in cutting; M. pickling. N. Finished product inspection.

classification:

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 0.1-4500mm, wall thickness range 0.01~250mm. In order to distinguish its characteristics, steel pipes are usually classified as follows.

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.

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.

Folding 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.

Specification sheet

China's stainless steel industry originated in the early 1980s, after so many years of development and exploration, in the domestic market has been quite well-known and certain influence. At present, there are more than 130 production enterprises, with a good momentum of development and expansion. The whole industry perforation equipment 38. Cold rolling, cold drawing equipment more than 500, smelting equipment 6, all using furnace refining, other equipment is relatively complete. The production capacity and scale of enterprises are constantly expanding and enhancing. In order to ensure the quality of products, water pressure, eddy current and ultrasonic flaw detection, direct reading spectrometer and other analysis and testing equipment are constantly increased and improved. Technical and managerial personnel with various senior and intermediate titles help enterprises step on the track of standardized production and management. The stainless steel pipe is exported to southeast Asia, the European Union dozens of countries and regions, deeply appreciated by foreign businesses and users.
