RSI Stainless Steel Threaded Flange

We are offering stainless steel threaded flange.
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.

d) 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.
all our materials shall carry test certificates , except those of non ferrous metals & the testing shall be done in govt.approved laboratory. We can also supply under third party inspections.
