ANSI/ASME B16.5 Flanges

ANSI B16.5 Class 150 Flanges, ASME B16 5 Blind flange dimensions

ANSI/ASME B16.5 Flanges range from ½ inches to 48 inches in nominal bore sizes. The specification for these flanges is ASTM A182. Steel India Company is a leading manufacturer and supplier of the flanges in various designs and dimensions. The ANSI b16.5 Slip on Flange is one of the flanges in this range that is usually used with seamless pipes for better fitting.

The slip on flanges allow the pipes to slip onto the flange so that the pipe can be fitted in place. The ASME B16.5 Flange can come in different pressure classes such as class 150 through class2500 and with different pressure numbers. The PN6 through PN64 pressure numbers are used to describe the pressure capacities of the ANSI B16 5 flange as well. The higher classes are used with high temperature and pressure services while the lower classes such as the ANSI B16.5 Class 150 Flanges are used with low pressure applications. There are applications like the paper and pulp industry, sea water equipment, chemical equipment and pharmaceutical piping which use the EN 1092-2 PN16 ASME B16.5 Flanges where there are high end applications as well. The Class 300 ASME B16.5 Pipe Flanges can be used in the power generation, gas processing, heat exchanger and in boiler class applications because of their high pressure capacities. Please feel free to contact us for more details and types such as the ANSI B16.5 Class 150 Pipe Flange and the price list.
