Analysis of the development of manufacturing stainless steel pipe fittings stainless steel pipe connection scenarios varied, the common types of compression fittings, compression type, union type, push, push threaded, socket welded, flanged, welded and welded connections with the traditional combination of derived series connection. These connections, according to its principle is different, its scope are different, but most are easy to install, solid and reliable. Connection with seal or gasket material, mostly selected in line with national standards of silicone rubber, nitrile rubber and EPDM rubber, eliminating the user's worries. Stainless steel pipe fittings stainless steel tube has been developed from a single to a martensitic stainless austenitic and ferritic duplex steel, high alloy steel; product varieties are seamless stainless steel pipe, welded pipe, thin-walled stainless steel tubes, etc., in different ways according to the classification into different stainless steel tube. Stainless steel tube basically covering the world standard varieties and specifications, more than 100 kinds of varieties, the product uses involving industrial and civil fields. After statistical analysis and probability analysis, the production of 70,000 tons in the last year, 25% were able to reliably used in petroleum, chemical, fertilizer, boiler and aerospace, nuclear power and other industries. About 60% can be applied in the food, brewing, pharmaceutical, paper, printing and dyeing, urban environmental protection and other industries. There are about 20% can be used as a nonconforming product or products, the main problems is the chemical composition of steel outside the allowable deviation; steel purity is not enough, excessive impurities, resulting in grain unqualified; not by heat treatment production, resulting in intergranular corrosion failure; external surface defects serious, heavy leather, slag, not removed within the fold, serious side wall and so on. Industrial pipes fewer defects; sized industrial pipe diameter roundness and straightness presence unsatisfactory; decorative pipe exists ingredients tolerance, diameter and wall ultra-negative and poor serious problems. Automotive demand for stainless steel pipe a lot. It is estimated that only a Sino-US joint production BUICK Shanghai Volkswagen Santana cars and luxury sedans B5 annual consumption of stainless steel pipe fifty-six tons. In the aerospace industry requires high precision stainless steel pipes and tubes 200 tons full payment. Electronics, instrumentation, metallurgy and other industries stainless steel pipe required each year to 5000 tons. Beverages, wine, food, textile, printing and dyeing and other light industrial and medical and pharmaceutical industries, for equipment manufacturing and maintenance, the annual consumption of more than 20,000 tons of stainless steel pipe. Stainless steel pipes and water equipment, is the world's most advanced water purification material foundation, and some cities in the water and gas and other fluid transport has also started using stainless steel tube. Invested heavily in Wuhan City, the widespread use of stainless steel piping and equipment, 13 major water pipes and water tanks, etc. Set a renovation, but also in the shortest possible time, in the new high-rise residential and office buildings, stainless steel piped water. Ningbo, Daqing and other places, some residents of water supply pipes, also has started using stainless steel pipes. Future areas of civil stainless steel pipe will be a huge market.
