Class 150 Forged Flanges is made up of cast or forged material. Each class has a specific pressure and temperature rating. For instance, 3 Inch Class 150 Flange at ambient temperature is rated at 270 Psig, and 180 Psig at 400 degrees F. ANSI B16.5 150 Flange at 600 degrees F is said to have 150 Psog and at 800 degrees F is said to have 75 Psig.
From the above example, we can infer that as the temperature goes up the pressure rating of ASME B16.47 Series A Class 150 Pipe Flanges goes down and vice versa. Moreover, MSS SP 44 Class 150 Flanges are made up of various materials such as ductile iron, stainless steel, carbon steel, and cast that provide different pressure ratings to the Series B 150lb Flanges. These flanges can be used in applications as described in the standards B16 series. The standard Awwa Class 150 Flanges also mentions the tolerance to flange gasket.
Carbon And Stainless Steel Flanges - ASME/ANSI Class 150 manufacturer In India internally machine polishes the surface to a maximum ID surface finish of 20 RA prior to electropolish. Polished 150# Flange that has been electropolished at 15 RA are used for critical processes. Pn16 150 Lb Flange assist in the efficient flow of fluid at a medium rate. They can be used in boilers and pressure vessel codes along with the B31 piping code. ASA B16 5 Class 150# Welding Neck Flange manufactured by us displays all the properties as per the international standards.

What Is Class 150 Flange?
Flanges were initially designed to connect pipes of various sizes together. However, with time they have evolved and are currently are available in various grades depending upon the end application requirements. Class 150 Flanges is one such type of flange that belongs to the rating class 150.
What Is The Difference Between Class 150 And 300 Flange
Class 150 Flange: The pressure rating for these flanges ranges from 86 PSIG for class B flange to 300 PSIG for class F flange.
Class 300 Flange : At a temperature range of 600 degrees F 6 Inch Class 300 Flange has a pressure rating of 570 psi.
