Kaysuns - Stainless Steel Flange
Stainless Steel Flange is an indispensable part for a stainless steel piping system, that connects the pipe to another pipe or pipe to a valve. There are holes in the flange, and get the assembly with bolts tightly.
Pipe flange is a disc-shaped part, which is most common in pipeline engineering. Stainless steel flanges are used in pairs or match with the flanged valves. In pipeline engineering, flanges are mainly used for pipe connection. It has different connected end, such as butt-welding, socket-welding, threaded etc. Different pressure flanges have different thicknesses and use different connection type.
Kaysuns supplies stainless steel flanges for oil and gas, chemical, offshore, marine etc. since 2007. We mainly provide flanges in materials: stainless steel 304/304L, 316/316L, 316Ti, 321, 321H, 347H, 317L, 310S, 904L, 254 SMO (A182 F44), duplex 2205, super duplex 2507 and nickel alloy such as monel 400, Hastelloy C276, Inconel 600, 625, 800H, 825 etc, with standard ASME B16.5, EN 1092-1, JIS B2220, AS 2129 etc. We also accept customized forging upon the design and drawing of client.

Our Capacity
Our capacity is about 400 tons/month for every type flanges. We produce and supply the flanges from Class 150 to Class 2500, stainless steel and duplex steel flange are our strength.
Rate: 150LBS~2500LBS
Dimension: 1/2” to 72” (DN15 ~DN1800)
Quality Control
Every flange will be inspected before shipment, including NDT ( PT, MT or UT test), dimension control, PMI test. The chemical analysis and mechanical properties test is per heat number, corrosion test and other inspections are upon client’s requirement.
Flange Packing
For the flange size < 10”, we mainly packed them in plywood box. For large diameter Flange, they will be packed in pallets if there is no specifics.
