Ansi B16 5 Class 1500 Flange Dimensions

Ansi B16 5 Class 1500 Flange Dimensions range from ½ inches to 24 inches in nominal sizes. The wall thicknesses, outer diameters and base and hub sizes all depend on the ANSI B16.5 standards. The pressure classes range from 150 through 2500 representing the pressure capacities from 150lbs to 2500lbs. The Class 1500 Lb Flange Dimensions allow the flanges to hold 1500lbs of force.

ANSI B16.5 1500 Lb Flange

ANSI B16.5 1500 Lb Flange

This is one of the high pressure capable flanges. There are different types of flanges. The slip on flanges, blind flanges, weld neck flanges and socket weld flanges are all used under specific application requirements. The 1500 Lb Blind Flange Dimensions are used to close a pipeline. The blind flanges can come in different shapes as well. They are used in high frequency maintenance systems to open and close the pipelines as needed. Sometimes, the blind flanges are used to close a pipeline permanently. The ansi 1500 lb flange dimensions vary for different types of faces. The raised face, flat face and ring type joint flanges have separate dimensions for the raised face and the ring as well. The 1500 LB Flange Dimensions are used in the selection of flanges and the materials. A few applications require high tensile, high corrosion resistant material. High alloy materials can handle high pressure and high temperatures as well. The Class 1500 lb slip on flange dimensions and other flange dimensions are selected according to the material grade and standard specifications to suit the application requirements.
