Ring Type Joint Flange
Stainless Steel RTJ Flanges manufacturer in India.
What Is A Ring Type Joint Flange?
There are different faces for a flange. These faces have the preliminary use as contact surfaces. Usually, the sealing gasket sits on this face and thus seals the connection. The Flat Faced Ring Type Joint Flanges have a flat face that is not raised. The rtj flange dimensions vary according to standards and needs. We have a detailed rtj flange weight chart for our clients to make the selection easy. The standards for RTJ Flanges make them fit under 24 inches. Ring Type Joint Weld Flange has a groove in the ring so that the gasket often squeezes into the groove. Ring Type Joint Raised Face Flanges have a raised face for extra grip and easy handling as well as strength. ANSI B16.5 Class 150 Ring Type Joint Flanges are one of the low pressure class flanges. Stainless Steel Ring Type Joint Flanges can also come in other dimensions.

What Is Rtj Gasket?
Ring Type Joint Flanges excerpt more pressure on the gasket for extra tightness. RTJ Flanges can therefore increase the pressure containment capacity at the connection. ASME B16.47 Series A and B RTJ Flanges have different number of bolt holes and can range from 26 inches to 60 inches in diameter. Ring Type Joint Forged Flanges are made to perform better than the cast flanges. Ring Type Joint Flange is made up of A182 material which is a stronger alloy.
How Does A RTJ Flange Work?
RTJ Flange can differ according to the material and the standards. Alloy Steel Ring Type Joint Plate Flanges have a plate or ring attached to the joint. Nickel Alloy 200 RTJ Flange is lighter than the Carbon Steel Ring Type Joint Flange. MSS SP-44 Ring Type Joint Flanges and Duplex Steel RTJ Flanges can perform better than other materials because they are stronger. Hastelloy C22 Ring Type Joint Flange and the Inconel Ring Type Joint Flanges are lighter and can be applied to specific applications.
