MSS-SP-75 WPHY 42, Butt Weld Fittings Manufacturer

MSS SP-75 is a standard for high yield wrought grade butt-welded fittings while also covering factory-made, seamless and electric fusion-welded fittings. Typically carbon and low-alloy steel are used to manufacture butt-welding MSS SP-75 Fittings. This standard acts as a guideline for manufacturers involved in the production of these fittings. High pressured industries like the gas and oil use these MSS SP 75 Weld Fittings for transmission and distribution in their piping systems.

The Standard Practice for the production of these fittings governs certain parameters such as dimensions, pressure ratings, testing methods, tolerances, A860 MSS SP 75 Material, chemical and tensile properties, notch toughness properties, heat treatment, manufacture as well as marking. These parameters are well suited for the production of high-test, butt-welding fittings like the MSS SP 75 Pipe Reducers that are sized between NPS 60 and smaller. Dimensional requirements for fittings which are sized NPS 14 and smaller are presented by attributing ASME B 16.9. All fittings such as the Buttweld MSS SP-75 Elbow manufactured in accordance with this Standard is designed to withstand a field hydrostatic test pressure. It also mentions a pressure level comparable to the expected development of hoop stress, which in turn is equal to the specified minimum yield strength for the pipe of an equivalent grade along with the thickness of the MSS SP 75 Tee wall based on Barlow’s Formula. This is to be taken into consideration keeping the following details in mind i.e. without failure, leakage, or even the impairment of serviceability.
