What Is A Stainless Steel Flange?

Our Stainless Steel Pipe Flanges conform to the standards with different faces and pressure classes. Our Stainless Steel Exhaust Flanges are suitable for connection with exhaust pipe and manifold system. Stainless Steel Header Flanges make it viable for the exhaust systems to be connected to the cylinder head. Stainless steel flange manufacturers in India produce different types of flanges. We produce different types of flanges.

ASTM A182 SS Flanges Different Type Use In Pipeline?

Stainless Steel Screwed Flanges are the ones with a screwed connection type that has threads in the bore. In places where the piping cannot be disassembled, the Stainless Steel Split Flanges can be used in two pieces to fit them together. Stainless Steel Square Flanges are commonly used in a pipe to component basis where they give an excellent hold with the component. We supply different pressure classes of flanges. For example the ANSI 150 Stainless Steel Flanges that belong to the Stainless Steel Class 150 Flanges and other classes are available from us. Rajtilak Metal is one of the leading stainless steel flange manufacturers in India.

What Use Of Large Diameter Stainless Steel Flanges Hydraulic Systems?

AWWA Stainless Steel Flanges are used mostly in water services. In applications where high pressures are possible like in hydraulic systems, the High Pressure Stainless Steel Flanges are used. In water supply and other larger supply volumes, the Large Diameter Stainless Steel Flanges are used to connect larger pipes. For applications which require thin and light weight pipes, the Metric Stainless Steel Flanges are used. In complex systems where multidimensional pipes are interconnected, our Stainless Steel Reducing Flanges are handy. SS Flanges come with different forms and faces such as Stainless Steel Raised Face Flanges and others. There are different standards by which the dimensions are governed. Pn16 Stainless Steel Flanges for example are governed by DIN 2501 and ISO 7005 standards.
