Everything Else

Industrial piping systems in oil, gas, petrochemical, and desalination sectors largely depend on precision flanges made by ASME B16.5 and B16.47 standards in the pressure classes between 150 and 2500. In process lines that carry corrosive media, the stainless steel slip on flange is often chosen for its simplicity in aligning and dual fillet weld pattern, especially in schedules from SCH 10 to SCH 160. These flanges which come in ASTM A182 F304, F304L, F316, and F316L are mainly made in sizes from ½ inch to 24 inches, with bigger sizes being custom forgings. On pipingmaterial.sa, a B2B platform that caters industrial buyers in Riyadh, Jeddah, and Dammam, the stainless steel slip on flange is a connecting link of procurement teams with verified suppliers who are offering EN 1092-1 and ANSI drilling patterns, thus ensuring dimensional accuracy and PMI-tested materials.

Flow measurement and differential pressure applications require highly advanced components such as stainless steel orifice flanges, which are generally produced to ASME B16.36 standards. These flanges have tapped pressure ports and are typically used with orifice plates in beta ratio controlled systems. The materials are the same as for the slip-on flanges but may also be duplex grades like ASTM A182 F51 for higher strength and resistance to chlorides. PTFE gaskets including RF, RTJ, and FF are chosen based on the conditions of the service, while pressure classes up to 900 are typical in refinery installations. On pipingmaterial.sa, stainless steel orifice flanges can be purchased from audited stockists and exporters, thus contractors can source trusted and verified suppliers suitable for project specifications.
