ASME B16.11 A105 Class 3000 Forged Fitting Tee
ASME B16.11 is the standard for the forged steel fittings, including socket weld and threaded type. Material including carbon steel, alloy steel and stainless steel. Also described as Class 2000, 3000, 6000 threaded end fittings and Class 3000, 6000, and 9000 for socket weld end fittings.
Forged steel fittings named by their manufacturing processes forging, which to heat the carbon or alloy steel in a transforming temperature and modes the heated parts into the desired shape. Then use machining process to make a forged steel fittings.
Forged pipe fittings is in high quality which with higher strength and could bear high pressure. To this fittings you should pay attention to have a uniform wall thickness since they have to be through threading process or machined to socket weld end.
The types of pipe fittings ( differentiated by grade and specification) included in this standard is shown as below:
Including socket weld fittings and threaded fittings size in NPS inch. For example the 45 and 90 degree elbow, its size range is 1/2" to 4", and the classes of the product are ranging in 3000, 6000 and 9000 lbs.
