Butt Welding Pipe Fittings Stainless Steel Elbow 90D Long Radius Bend A403 WP304 ASME B16.9
Butt welded pipe fittings are pipe fittings made of welded pipes, for pipe fittings manufacturers, the forming
process of using welded pipes is basically the same as the forming process of using seamless pipes, and
the forming process of butt welded pipe fittings does not include welding processes; The other is the welding
process required by the pipe fittings manufacturer to complete the forming of pipe fittings, butt welding flange
is one of the flange pipe fittings, widely used and promoted in different fields and industries, the scope of
application in use is different, the environment that needs to be used is also different, and it needs to be
used in accordance with certain conditions. Butt welding elbow is completed by welding two steel plates,
generally large-diameter elbows are this process, and the general diameter above 600 is basically butt
welding elbow.
Production standards: national standard, American standard, Japanese standard, British standard,
German standard, etc.
Material specifications: stainless steel, carbon steel, low alloy steel, alloy steel, etc
Applicable medium: gas, liquid, steam.
Connection method: butt welding (welding) type.
Different pipe fittings product standards have different regulations for heat treatment. Not all deformed
fittings are heat treated. Wall thickness 2-55, mode of transport car, train, ship. Packing method: baling,
painting and cracking. Weight overweight and theoretical weight. The purpose of heat treatment is to
eliminate the work hardening, residual stress, metal deformation defects, etc. caused by the forming
process, so that the metal structure and properties of the pipe fittings after forming change, restore to
the state before deformation processing or improve and improve their performance.
