Pipe Fittings The pipe is a part of a pipe that is connected to a pipe. According to the connection method can be divided into socket-type pipe, bouncing double-melting pipe fittings, threaded pipe fittings, flange fittings and welded pipe fittings. Use the same material as the tube. Elbow (elbow), three-way tube, four-way tube (cross head) and reducer (size head) and so on. Elbow for the place where the pipe is turned; the three-way pipe is used for the collection of three pipes; the four-way pipe is used for the collection of four pipes; the reducer is used for the connection of the two pipes of different diameters
There are many types of fittings, which are classified according to their use, connection, material, and processing.
By use points
1, for the tube connected to the tube are: flange, live, pipe hoop, clamp, card sets, hose clamps, etc.
Cold drawn welded tee
2, change the tube direction of the pipe: elbow, elbow
3, change the pipe diameter of the pipe: Reducing (reducer), reducer elbow, pipe support, reinforcement
4, to increase the pipe branch of the pipe: three links, four links
5, for the pipeline seal of the pipe: gasket, raw material with, linen, flange blind plate, pipe block, blind plate, head, welding plug
6, for the pipe fixed pipe: clasp, drag hook, rings, brackets, brackets, pipe cards, etc.
Pipe Fittings China is already the world's largest producer and consumer of building materials. The main building materials products cement, flat glass, architectural sanitary ceramics, stone and wall materials and other production for many years ranked first in the world. At the same time, building materials, product quality continues to improve, energy and raw material consumption decreased year by year, a variety of new building materials continue to emerge, building materials products continue to upgrade, Cangzhou pipeline equipment manufacturing industry base is strong. Existing production enterprises more than 3200, of which more than the scale (sales income of more than 5 million yuan) 222 enterprises, employing 124,000 people. The main products are all kinds of special steel, stainless steel, carbon steel and other caliber seamless steel pipe, low pressure boiler tubes, oil drilling pipe and other steel pipe; all kinds of three, four, valves, All kinds of polyethylene pipe, polypropylene pipe and other plastic pipes, a total of 16 categories of more than 370 varieties of more than 3500 kinds of various types of stainless steel flanges, forging flange; all kinds of pipe rack, instrument, oil anti-blowout device and other pipe fittings; specification. The main manufacturing process is hot-rolled straight seam welding, spiral double-sided submerged arc welding, forging, forging, IF push, cold forming, hot extrusion, pipe processing diameter of 2020 mm. Products are widely used in municipal, petrochemical, West-East, ship and nuclear power engineering areas, the design and processing capacity of 25 million tons. 2010 above-scale enterprises to achieve industrial added value of 13 billion yuan, an increase of 31.7%, accounting for all enterprises above designated size 16.1%. Cangzhou pipeline equipment manufacturing industry is the "three on" (on the scale, on the level of equipment) and the "three high" (high-end, high pressure, high value-added) goal, urging pipeline equipment manufacturing capacity of 30 million tons. Cangzhou will become well-known at home and abroad, "pipeline equipment manufacturing and R & D base" and "pipeline equipment". "Eleventh Five-Year Plan" infrastructure investment has been chess to the plate, roads, railways and other infrastructure construction investment growth and the growth of ordinary civil construction investment, so that the construction industry is in the boom up stage. At the same time, in the construction of energy-saving society and the country to strengthen the capacity of independent innovation in the context of energy conservation and technological innovation theme will be the development of the industry hot
