SANS/ SABS 1123 Flanges
The SANS/SABS 1123 flange stands as a standard in flange design established by the South African Bureau of Standards (SABS), widely adopted across the African market. Primarily designed for low-pressure pipelines and equipment, this flange standard finds applicability in diverse industries including petroleum, chemical, and power, etc.
The SABS 1123 flange is identified by the specific standard number 10554, featuring a round flange face type. This standard is categorized into two grades: Grade 1 and Grade 2, each with distinct flange parameters. Selecting the appropriate standard of SABS 1123 flange involves considering factors such as the usage environment, pressure requirements, connection conditions, material type, and specific flange dimensions based on the prevailing conditions. For instance, the SABS 1123 Table 1000/3 flanges are well-suited for applications in nuclear power plants, heavy oil refineries, and bitumen upgraders.
To cater to diverse application requirements, the SANS/SABS 1123 flanges are crafted from a variety of materials, including stainless steel, carbon steel, alloy steel, and duplex steel. This ensures that the flanges meet the specific demands of various applications.
