Repute Steel & Engineering Co. is a trusted manufacturer, stockist, and exporter of Stainless Steel Lap Joint Flanges, offering high-quality products that meet the stringent demands of various industries. Stainless Steel Lap Joint Flanges are used in applications where frequent disassembly of flanged connections is required. These flanges are ideal for pipe systems that need to be easily assembled and disassembled, making them popular in industries like chemical processing, oil and gas, marine, and power generation. The design of Lap Joint Flanges consists of two components: a stub end and a backing flange, which allows for easy alignment and removal.
Manufactured with premium stainless steel grades such as SS 304, SS 316, SS 316L, SS 310, and SS 321, Repute Steel & Engineering Co. ensures that the Lap Joint Flanges possess exceptional strength, corrosion resistance, and durability. Stainless steel’s inherent resistance to oxidation, pitting, and crevice corrosion makes it an excellent choice for harsh environments. The material selection allows the flanges to perform effectively in both high and low temperatures, making them suitable for diverse piping systems that handle corrosive fluids or gases under varying pressure and temperature conditions.
Repute Steel & Engineering Co. produces Stainless Steel Lap Joint Flanges according to international standards such as ASTM A182, ASME B16.5, ANSI B16.47, and API 605, ensuring that all products meet the required mechanical and dimensional specifications. This adherence to global standards guarantees compatibility with other flange types and smooth integration into various pipeline systems. The company also offers custom manufacturing services, allowing clients to request specific sizes, grades, and finishes to meet the unique requirements of their projects. Whether customers need standard or customized flanges, Repute Steel & Engineering Co. is equipped to deliver precisely what is needed.
