The ASME B16.5 - 1996 is a standard for Pipe Flanges and Flange Fittings that could be used in piping systems of various industries. The specified ASME B16.5 Class 600 Flange covers materials, tolerances, pressure-temperature ratings, marking and testing. Moreover, this standard also covers 600 Lb Flange Dimension and methods of designating openings for pipe flanges and flanged fittings.
Using the Rtj Blind Flange Class 600 aids the worker in stopping the flow of media across a piping system. Since the blind flange does not have a bore in its centre, using this component effectively seals off valves, pumps or piping systems. A Slip on Flanges is a ring which is placed over the pipe end, with the face of the flanges extending from the end of the pipe until such a distance where a weld bead could be applied on the inside diameter.

The OD of a Carbon Steel Slip On Flange Class 600 is also welded on the backside of the flange. The size range of these flanges is between NPS 1/2 through NPS 24, with the requirements of Class 600 Stainless Steel Flange has been given in both metric and U.S units. The ASME B16.5 is a standard, where requirements and recommendations for additional fittings such as the flanges bolting, flanges gaskets, and 600# Flange Pressure Ratinge joints have been detailed as well.
