Pipe fittings in the pipe system is the connection, control, turn, shunt, seal, support the action such as spare parts. Over 08 year financial crisis, the economy continues to rebound, major infrastructure construction as "much starker choices-and graver consequences-in planning" kicked off the new curtain, pipe demand will continue to grow in the future. Pipe is oil refining industry, chemical industry, power industry, oil and gas pipeline construction project, ship manufacturing industry and machinery manufacturing industries such as necessary components, has wide downstream market.
In the metal pipe fittings industry, small diameter and low pressure, mainly carbon steel material pipe fittings, mainly used in the technical requirements of metal pipe no special operation environment, known as general metal fittings; And relative to the general pipe, large diameter, high pressure, use high grade material, alloy steel materials or special metal material manufacturing, its application field of industry with strong professional and pertinent fitting, is known as special metal pipe fittings or high-end metal pipe fittings. Metal pipe fittings manufacturing industry in china, can be divided into general metal pipe fittings manufacture, and the high-end metal pipe fittings manufacturing.
At present, the domestic production enterprises of metal pipe is very much, but much smaller, are engaged in general metal fittings manufacturing, really can produce high quality, high technical content of the high-end metal pipe fitting enterprise is less.
Metal pipe fittings industry development for nearly 30 years in our country, by the end of 2010, the national oil pipes and pipe fittings manufacture, gas pipe and pipe fittings manufacture, municipal engineering pipes and pipe fittings manufacture, and insulation, refrigeration fittings, which has more than 4000 manufacturing enterprises, which is engaged in the metal tube has reached more than 1900 manufacturing enterprises. But in these metal pipe fittings manufacturer, contains a large number of small and medium-sized enterprises, production technology content is low, the problem such as lack of core technology, are often limited is engaged in metal pipe fittings manufacturing in general. To amount standards, however, the market capacity is concentrated in the high-end metal pipe fittings manufacturing. To distinguish from the pressure, high pressure pipe fittings manufacturing business accounts for only 35% of the total number of metal pipe fittings industry enterprises, but to create the industry output value of 60%.
High-end fitting in molding technology, welding technology, heat treatment technology, testing technology, the design level, has a large room to improve. With refinement of social division of labor, the downstream industry in high-tech development in pursuit of social benefits and economic benefits of a win-win situation, technical requirement of pipe fitting products, make high-end fitting to the market demand is in constant growth. Industry development up to now, in the high-end pipe segments also have produced some of the leading enterprises, such as oil and gas transmission pipe fittings market leader is yaang pipe industry - in the field of oil gas and chemical control of the market share ranking the first; The market leader of ship fittings is zhongnan heavy industry, has been successful Now the domestic market; In the nuclear power, The market leader is xinfeng pipe fittings - has the most advanced domestic nuclear power pipe fittings manufacture, inspection technology.
