China is already the world's largest producer and consumer of elbow construction materials. The output of main building materials such as cement, flat glass, building and sanitary ceramics, stone and wall materials has been in the top for many years. At the same time, the quality of building materials products 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 products are continuously upgraded.
Elbow products include various special steel, stainless steel, carbon steel and other seamless steel pipes, low, medium and high pressure boiler tubes, oil drilling pipes and other steel pipes; various tees, crosses, valves, reducers, etc. Pipe fittings.
All kinds of stainless steel flanges, forged flanges; all kinds of pipe racks, instruments, oil blowout preventers and other pipeline accessories.
All kinds of polyethylene pipes, polypropylene pipes and other plastic pipes, a total of 16 categories, more than 370 varieties, more than 3500 specifications.
The elbow 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 large processing diameter of the pipeline is 2020 mm.
The products are widely used in engineering fields such as municipal administration, petrochemical industry, west-east gas transmission, shipbuilding and nuclear power, with an annual design and processing capacity of 25 million tons.
Elbow enterprises realized an industrial added value of 13 billion yuan, a year-on-year increase of 31.7%, accounting for 16.1% of the added value of all enterprises above designated size.
The elbow pipe equipment manufacturing industry is moving towards the goals of "three tops" (upscale, high level, and high 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 .
It will become a well-known "pipeline equipment manufacturing and R&D base" and "pipeline equipment capital" at home and abroad.
The planned infrastructure investment 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 the industry. Plastic pipe fittings and pipes once again set off a pipe fitting boom.
Carbon steel elbow: ASTM/ASME A234 WPB, WPC alloy: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP911, 15Mo3 15CrMoV, 35CrMoV Stainless steel: ASTM/ASME A403 WP 304 -304L-304H-304LN-304NASTM/ASME A403 WP 316-316L-316H-316LN-316N-316TiASTM/ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H

Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leaching, PVC, PPR, RFPP (reinforced polypropylene), etc.
According to the method of making the elbow, it can be divided into pushing, pressing, forging, casting, etc.
According to the elbow manufacturing standard, it can be divided into national standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
According to its radius of curvature: it can be divided into long radius elbow and short radius elbow. Long radius elbow refers to the outside diameter of the pipe whose radius of curvature is equal to 1.5 times, namely R=1.5D; short radius elbow refers to its radius of curvature equal to the outside diameter of the pipe, namely R=1.0D. (D is the diameter of the elbow, R is the radius of curvature).
According to the pressure level: there are about seventeen types, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; among them, STD and XS are commonly used.
According to the different shapes and uses of the elbow, it can be divided into: groove elbow, ferrule elbow, double-bearing elbow, flange elbow, reducing elbow, seated elbow, inner and outer tooth elbow, stamping elbow , Pushing elbow, socket elbow, butt welding elbow, inner wire elbow, etc.
