What Does Mean By Ansi Class 150?


The American National Standards Institute, or as referred to as ANSI B16.5 Class 150 Flange is a system of dimensional standards. These dimensions cover various grades of flanges for instance - b16.5 class 150LBS flanges, weld neck, slip-on, lap joint, socket weld and threaded flanges as well. ASME B16.5 Class 150 Forged Flanges considers several characteristics of flanges, such as its wall thickness, diameter, length and weight. These characteristics of the 150# Flange are a set of parameters which act as a guide for both manufacturers as well as engineers across the globe. The materials used in the manufacture of series a class 150 flanges is ductile iron.

Hence, ansi b16.5 class 150 flange dimensions in mm are designed to be used for applications in different sectors such as oil, steam, or chemical because this class of flanges is able to meet their demand for good performance in high pressure. The mechanical and chemical properties of ansi b16.5 150# Flange Dimension confirms to ASTM A105. Unless otherwise specified, class 150 weld neck flanges will be furnished with a 1/16 inch raised face, although the flat face option is available. Since we specialize in the production of these slip on flanges class 150, we are known to be the best supplier, distributor and class 150 flanges manufacturers in India.
