ANSI B16.9 Pipe Fittings Stainless Steel Butt Welding Cap Used To Close The Pipeline

Butt-welded pipe caps are pipe fittings welded to the end of a steel pipe to cover the pipe. It is used to close the pipeline and has the same function as pipe plugs and plugs. Butt-welded pipe caps have a variety of shapes, mainly including convex shapes, cone shells, variable diameter sections, flat caps and shrinkage ports.

Cap application

China is already the world's largest producer and consumer of building materials. The output of main building materials products such as cement, plate glass, building and sanitary ceramics, stone and wall materials has ranked first in the world for many years. At the same time, the quality of building materials continues to improve, the consumption of energy and raw materials is declining year by year, various new building materials continue to emerge, and building materials are constantly upgraded. Cangzhou has a solid foundation for the pipeline equipment manufacturing industry. There are more than 3,200 production enterprises, of which 222 are above-scale (sales income of more than 5 million yuan) with 124,000 employees. The main products are various kinds of seamless steel pipes of various calibers such as special steel, stainless steel, carbon steel, low, medium and high pressure boiler pipes, oil drilling pipes and other steel pipes; various tees, crosses, valves, reducers and other elbow pipe fittings ; Various stainless steel flanges, forged flanges; various pipe racks, instruments, oil blowout prevention devices and other pipe fittings; various polyethylene pipes, polypropylene pipes and other plastic pipes, a total of 16 categories, more than 370 varieties, more than 3500 kinds specification. The manufacturing process mainly adopts hot-rolled longitudinal seam welding, spiral double-sided submerged arc welding, forging, forging, intermediate frequency pushing, cold forming, hot extrusion, etc. The maximum processing diameter of the pipeline is 2020 mm. The products are widely used in engineering fields such as municipal administration, petrochemical industry, west-to-east gas transmission, shipbuilding and nuclear power, with an annual design and processing capacity of 25 million tons. In 2010, enterprises above designated size achieved industrial added value of 13 billion yuan, a year-on-year increase of 31.7%, accounting for 16.1% of all enterprises above designated size. The Cangzhou pipeline equipment manufacturing industry is moving towards the goals of "three highs" (higher scale, higher level, and higher equipment) and "three highs" (high-end, high pressure, and high value-added), and strive to promote the pipeline equipment manufacturing capacity to reach 30 million tons. Cangzhou will become a well-known "pipeline equipment manufacturing and R&D base" and "pipeline equipment capital" at home and abroad. Infrastructure investment in the "Eleventh Five-Year Plan" plan has reached the mid-range. The explosive growth of investment in infrastructure construction such as roads and railways and the steady growth of investment in ordinary civil construction have put the construction industry in a booming stage. At the same time, in the context of building an energy-saving society and the country's strengthening of independent innovation capabilities, the theme of energy conservation and technological innovation will be a hot spot for industry development. Now plastic pipe fittings and pipes once again set off a pipe fitting boom.
