Applications of Weld Neck Flange
A weld neck flange consists of a circular fitting with a protruding rim around the circumference, and it is connected with pipe by welding neck. Weld neck flange is not easy to cause deformation, with good sealing. It is suitable for high temperature, high pressure and low temperature pipe or pipes of fluctuant pressure and temperature. In this case, the nominal pressure is no more than 2.5 MPa, and advantage is that the price is cheaper; Weld neck flange also is used for the pipeline that transport flammable and explosive medium with expensive transportation price. Under the circumstances, the nominal pressure is at around 16MPa. The connection of weld neck flange is convenient and it can withstand greater pressure. According to different levels of pressure, the material of weld neck flange gasket should be different ranging from low pressure asbestos gasket, high pressure asbestos gasket to metal gasket.
Weld neck flange is a kind of flanges, widely used and promoted in machinery industry, which has got the praise and favor form users. Weld neck flange has a wide range of applications and different uses depends on different characteristics. It is mostly used in the mild conditions of medium, such as low pressure compressed air and low pressure circulating water. The price is relatively cheaper.
Applications:
1. The extension of artifacts: the butt welding of strip steel, profile steel, wire rod, reinforcing steel, boiler steel pipe, oil and gas pipe.
2. The butt welding of ring artifact: the butt welding of car rim, bicycle, motorcycle rims and other chain rings.
3. Assembly welding of parts: to weld simple rolling, forging, stamping or machined parts into complex parts can reduce costs. Such as the butt welding of car direction shaft housing and rear axle shell, the butt welding of various connecting rod and draw rod, as well as the butt welding of special parts , etc.
4. The butt welding of dissimilar metal: can save precious metals and improve product performance. Such as the butt welding of work part of the cutter (HSS) and tail (medium carbon steel), the butt welding of head (heat resistant steel) and tail (constructional steel) of exhaust valves of internal combustion engine, the butt welding of conductive couplings of aluminum copper, etc.
The application of weld neck flange need to be determined according to the specific situation, ensuring the specific use value and performance and withstanding high temperature and high pressure. Weld neck flange is suitable for the steel pipe connection whose nominal pressure of not more than 2.5 MPa.
The sealing surface of weld neck flange can be made into three kinds: smooth type, concave and convex type and mortise type. Smooth type weld neck flanges are mostly used, the other two ways of weld neck flange in use also is common.
