Product Description
Threaded Flanges are similar to slip-on flanges in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. Threaded Flanges may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing the flanges' pressure applications.
Specification of Stainless Steel Threaded Flanges:
1. Stainless Steel: ASTM A 182, A 240
2. Grade : F 304, 304L, 304H, 316, 316L, 316Ti, 310, 310S, 321, 321H, 317, 347, 347H,904L, Duplex stainless steel UNS S31803, 2205, Super Duplex stainless steel UNS S32750
3. Size: ANSI B 16.5 from 1/2" to 24" and classes150 to 2500 (complete range)
4. Pressure: ANSI class 150 to 2,500

Applications of Stainless Steel Threaded Flanges:
These flanges are used in special requirements to work under high temperature and pressure, making sure no welding joint is made at the assembly.
