Detailed Information

Flange rating or class is a term that refers to the maximum pressure (in either psi or bars) that a flange  can withstand at increasing temperatures. Those flanges which have a higher rating or class tend to be stronger as compared to flanges that have a lower class or ratings.  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.

1500 lb rtj flange dimensions made in different materials will demonstrate a different pressure-temperature performance even though they have the same rating.  Pressure rating of a flange can be defined as the maximum allowable pressure that a flange could withstand at increasing temperatures. According to the specification for ANSI/ASME B16.5, there are seven flange pressure ratings or pressure classes. These seven pressure ratings are as follows – 150, 300, 400, 600, 900, 1500, and 2500. 1500 lb rtj flange dimensions  for the ASME B16.5 – Pipe Flanges as well as  Flanged Fittings: NPS 1/2 Metric/Inch through NPS 24 Metric/Inch Standard.

1500 LB Flange Dimensions includes the Bolt circle diameters, which are about 1/8 inch larger as compared to the bolt diameter. Generally, terms such as pressure rating, #, class, Lb or Lbs are interchangeable. Which means that  all the fore mentioned terms refer to the same exact concept of pressure and temperature performance of a flange. Besides flanges, these terms may also be used interchangeably for other equipment such as valves, fittings, etc.

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.
