Difference between neck butt welding flange and neck flat welding flange
1. The weld forms are different: the weld between the pipe with neck flat welding flange and the flange is a fillet weld, while the weld between the pipe with neck butt welding flange and the pipe is a circumferential weld;
2. Different materials: the material of the neck flat welding flange is machined from the ordinary steel plate with the thickness meeting the requirements, while the material of the neck butt welding flange is mostly machined from forged steel parts;
3. Different nominal pressures: the nominal pressure of the neck flat welding flange is 0.6-4.0mpa, while the nominal pressure of the neck butt welding flange is 1-25mpa.
4. Another point is that the welds connecting the neck butt welding flange and the nozzle belong to class B welds, and the welds connecting the neck flat welding flange and the nozzle belong to class C welds. The post welding NDT is different.
5. The neck flat welding flange and the neck butt welding flange cannot be replaced at will. From the perspective of manufacturing, the neck flat welding flange (so is the abbreviation of slip on) has a large inner diameter, which means that the weight is small and the cost is low. In addition, the neck butt welding flange with a nominal diameter greater than 250mm (WN is the abbreviation of weld neck) needs to be tested, so the flange does not need to be tested, so the cost is low
2507 is a Ferritic Austenitic (dual phase) stainless steel, which combines the most beneficial properties of many ferritic steels and austenitic steels. Due to the high content of chromium and molybdenum in this steel, it has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion The dual phase microstructure ensures that the steel has high resistance to stress corrosion cracking and high mechanical strength
2507 stainless steel is used in the oil and natural gas industry; Offshore skyshattering oil platform (heat exchanger pipe, water treatment and water supply system, fire protection system, water spray system, water stabilization system; petrochemical equipment; desalination (Desalination) equipment (and high-pressure pipe and seawater pipe in the equipment); Mechanical and structural components requiring both high strength and high corrosion resistance; Combustion (waste) gas purification equipment. Main composition: 25cr-7ni-4mo-0.27n
