Metal Bellows Seals Mainly used in

China's metal bellows seal production and application began in the late 1950s, was mainly used in drainage, industrial anti-corrosion and other general purposes, variety, specifications, quality standards and product standards are relatively backward. After the reform and opening up, especially in the late 80s of last century, China's metal bellows sealing industry has been an unprecedented development. At present, metal bellows seal has become one of the main pipeline materials, for the development of urban and rural areas play an important role.

Demand-driven industry jump development

      China's production of plastic products is not very long time, metal bellows sealing industry in the reform and opening up has been relatively backward, the development of slow, and because the beginning is the plastic on behalf of the steel to plastic and wood as the main purpose, but the plastic products As a substitute for a conservation of materials, without the full publicity, the use of its own unique advantages, thus affecting the development of the industry.

      With the advanced technology into the developed countries, the upstream raw materials industry, technological progress, improve the quality of processing equipment, pipe material quality gradually increased, China's rapid economic development, but also for the metal bellows seal a lot of applications to create the conditions. In recent years, the construction industry, municipal engineering, agriculture, industry and other sectors of the market demand continues to increase, and further stimulated the rapid development of China's metal bellows sealing industry, the industry to improve production capacity and application, increase product variety, expand the application areas , To promote industrial scientific and technological progress, strengthen the standardization of construction has made great achievements.

      In recent years, China's metal bellows sealing production capacity has maintained rapid growth, variety, specifications continue to enrich, improve the quality, was scale, serial development. At present in the municipal and construction water supply and drainage, agricultural (drinking water and irrigation and drainage), municipal sewage, gas, heating, urban trenchless construction, industrial, communications, electricity, mining and other areas of metal bellows seal application ratio further increased. Some experts have analyzed, China's metal bellows sealed market share in the current proportion of all the pipeline is about 30%.

      In the product structure, the solid wall tube, bellows, ribs tube, winding pipe, foam pipe, inner spiral pipe and other structural pipe production and application. China has now become one of the largest varieties of metal bellows sealed. According to incomplete statistics, in 1990 the national metal bellows sealing output of less than 200,000 tons in 1993 to 250,000 tons in 1999 to 900,000 tons, while in 2001 to achieve 1.2 million tons in 2002 to 1.3 million tons , 1.5 million tons in 2003, 2 million tons in 2004, 2.4 million tons in 2005, 2.8 million tons in 2006, in 2007 China's metal bellows sealed total reached 3.5 million tons, has become an international Metal bellows seal production and application of one of the major powers.
