View SANS 1123 Flange Dimensions & SABS 1123 Flange Table

SANS 1123 Flanges follow the British standard for pipes, fittings and valves. The specification first emerged in 1962 and there are different SABS 1123 Flange Dimensions to suit different application needs. Rajveer Stainless And Alloys is a leading supplier of these materials in different shapes, sizes and specifications. These flanges are used for light duty applications and they are one of the older specifications available. There are other materials and specifications available to cover the SANS 1123 Flange Dimensions as replacements as well. Nevertheless, the SABS 1123 Table 1000 Flanges are still used with sizes ranging from ½ inches to 48 inches in the range of DN10 to DN 5000.

There are different pressure classes of the flanges to suit the different applications as well. They range from 150 to 2500LBs of pressure containment classes. There are different classes of these flanges as well. There are different tables that are prescribed for different applications too. The SABS 1123 Table 1000/3 Flanges for example are suitable for nuclear power plant applications, heavy oil refineries and in Bitumen upgraders. The SABS 1123 Flange Material is produced through forging, machining and heat treatments. The material could come with different finishes as well. We offer electroplating, coating and galvanization finishes. Please contact us with your custom requirements and we will serve you to the best.

Up to what temperature sabs 1123 pipe flanges are used?

The flanges can come in different standards and sizes. The B16.5 SABS flange can range from ½ inches to 48 inches in nominal diameter. They can operate on various temperatures. The range is between -10 degrees to 200 degrees Celsius. There are different pressure classes ranging from 150 to 2500. They can come in different types such as blind, weld neck, ring type joint, slip on, lap joint ring type and others. The flanges could be made as forged, threaded or screwed as well. Due to their temperature tolerance they can be applied in cryogenic as well as mild temperature applications.
