    ASME B Material including carbon steel, alloy steel and stainless steel. Also described as Class , , threaded end fittings and Class , , and for socket weld end fittings. Forged Steel 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 relevant contents will be shown in below tables in this article. Fitting Types and configuration 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.

    Table 1. Notes: Plug and bushings are not identified by class designation. They may be used for ratings up to Class designation. Special Fitting Pipe fittings with special threads or special flares can be manufactured upon negotiation between the supplier and the buyer. These fittings shall be considered to be in particular conformity to the standard if they are properly marked see Chapter 4 in ASME B Welding Installation welding requirements are outside the scope of this standard.

    Installation welding shall be in accordance with the applicable piping code or the operating procedures of the piping system in which the fitting is installed. Standard Measurement Units. The standard measurement unit for linear dimensions is inches. Values in millimeters are only for reference. Basis of Rating The schedule of pipe corresponding to each Class designation of fittings for rating purposes is shown in below table.

    Design temperature and other service condition shall be limited as provided by the applicable piping code or regulation for the material of construction of the fitting. With these limits, it defines the minimum pipe wall thickness.

    Table 2. The minimum pipe wall thickness calculation shall include pressure design and all applicable additional allowances e. Minimum Wall Thickness Tolerance Typically Table 3. Combination End Fitting Pipe fittings composed of socket welding and threaded ends shall be graded according to the shape of the end with a minimum rating from table 1.

    Pressure Test Capability This standard does not require a pressure test, but the fittings shall be able to withstand the hydrostatic test pressure required by the applicable pipe code to accommodate seamless pipe of material equivalent to the fittings forging and of the schedule or wall thickness associated with the fittings grade and end connection of table 2.

    NPS, followed by a dimensionless number, is the designation for nominal fitting size. NPS is related to the reference nominal diameter, DN, used in international standard. If the pipe fitting is a tee, the branch pipe size is given last.

    If the pipe fitting is a cross, the third dimension shall be the largest pipe opening, and then its relative opening specification.

    Cylindrical fittings shall be marked on the O. The marking of bushing and plugs is not required by this standard. Specific Marking The Specific marks should include but are not limited to the following: a.

    Material Identification. Product Conformance. The fittings in Section 1. Class Designation According to the applicable situation, it can be divided into , , or Alternatives the designation 2M, 3M, 6M or 9M may also be used depending on the application, where M is Size Material Standards Referred Standard Material Forgings, bars, seamless pipe or tubes can be used to make pipe fittings.

    Non Standard Material According to this standard, non-standard pipe fittings manufactured from other materials shall be marked in accordance with the agreement between the manufacturer and the purchaser, but the marking should not include the identification markings specified in 4. The concentricity tolerance of the opposing sockets should be within 0. Coincidence of Axes The maximum allowable variation in the alignment of the fitting bore and socket bore axes shall be 1 mm in mm 0.

    The maximum allowable variation in alignment of threads shall be 1 mm in mm 0.
