Detailed Information

Prashaant Steel & Alloys is a maker of Ansi B16.5 Class 150 Flange Dimensions of exceptional quality. Ansi B16.5 Class 150 Flange Dimensions are based on the ANSI B16.5 standard. It includes flanges of different types and material that range from ½ inches to 24 inches in nominal size. The outside diameter of the flanges range from 3.5 inches to 21inches. The minimum wall thickness for ½ inch flanges is 0.38 inches and the minimum wall thickness of the 24 inch flanges is 1.81 inches.

The 150 lb raised face flange dimensions apply for weld neck, slip on, socket weld, threaded, lap joint and blind flanges. These flanges are used in different applications to cater the application needs. There are different pressure classes. The 150 lb flange dimensions metric have the dimensions marked in metric scales. The flanges can range up to 2500lb pressure classes. There are series A and series B flanges under these dimensions. The flange supporting material dimensions range with the 30 150 lb flange dimension as well. The ring joint, gasket and flange bolts all come accordingly to suit the flange dimensions. The different types of flanges have different dimensions as well. The 150 lb weld neck flange dimensions have the neck size, flange size and the diameters differently measured. The application of the different types such as the neck weld flanges are in specific circumstances.
