China Forgings industry transformation and upgrading of the road
Forgingss are two parts of the pipe or other pipe fittings, including three links, four links, Forgingss, elbow, head, flange and so on. Industrial products are mainly used in the fields of petrochemical, natural gas, shipbuilding, electric power and medicine, especially in emerging fields such as marine engineering and nuclear power. The products are mainly used in the fields of petrochemical industry, natural gas, shipbuilding, electric power and medicine, especially in marine engineering and nuclear power. Space is huge.
The rapid development of industrial Forgingss downstream industry will drive the large demand for large diameter, composite materials, high performance and high reliability fittings. At present, the power industry demand for industrial metal pipe fell, mainly for the general performance, low technical content of the thermal power installed with the demand for pipe fittings decline. But the wind power flange, nuclear grade pipe fittings and large diameter, non-standard, high-performance thermal power unit pipe fittings and other key components, still in short supply, some need to rely on imports. With the acceleration of urbanization in China, the development of oil and gas fields, the transfer of ship orders in the world, the construction of marine resources, and the construction of nuclear power plants will lead to a greater supply and demand gap in the already short supply market.
Analysis of the next few years the country's low-pressure industrial metal pipe annual consumption of 1.5 million tons, high-pressure industrial metal pipe fittings annual consumption of about 2.3 million tons, plus export business, China's industrial metal pipe industry in the total annual demand of 4.5 million tons about. The world's annual industrial consumption of high-pressure pipe fittings at least 23.4 million tons, the market capacity of more than 90 billion US dollars.
Stainless steel pipe fittings need to have a certain slope, water supply stainless steel pipe fittings at the lowest point to install the drain plug or discharge valve, stainless steel pipe slope should be slope to the drainage device to facilitate the flow of stainless steel pipe flow and maintenance emptying. Stainless steel pipe fittings should be set to meet the following requirements: water supply stainless steel pipe fittings should be installed in the direction of the flow of stainless steel pipe pipe consistent with the direction of the slope should be consistent, slope should be straight. Water supply should be 0.002 ~ 0.005 slope, generally should ensure that the standard slope of 0.003 and slope to the water discharge device.
The production process of the high-pressure Forgingss first welds a polygonal ring shell with a polygonal cross-section or a polygonal fan-shaped shell with a closed end at both ends. After the internal pressure is filled with the pressure medium, the internal pressure is applied, and the cross section is changed from the polygon to the Round, and eventually become a circular ring shell. As needed, a circular ring shell can be cut into four 90 Forgings or six 60 high-pressure Forgingss or other specifications of high-pressure Forgingss, the process is suitable for manufacturing high-pressure Forgings diameter and stamping Forgingss Diameter ratio greater than 1.5 of any specifications for large Forgingss, is the manufacture of large national standard Forgings the ideal method.
The high pressure Forgingss are suitable for the pipeline system of petroleum, natural gas, chemical industry, hydropower, construction and boiler, etc. It is possible to save the equipment and mold cost without tube bulb as raw material, and can obtain any large diameter and relatively thin wall thickness For the above two reasons, can shorten the manufacturing cycle, the production cost is greatly reduced. Because it does not require any special equipment, especially suitable for large-scale national standard Forgings processing. Billet for the flat or can be developed surface, and thus the material is simple, easy Guarantee, easy assembly and welding
