ASME B16.5 Stainless Steel Blind Flanges manufacturer in India
Jignesh Steel is a Stainless Steel Pipe Flanges Manufacturer with a wide range of products and steel grades. There are different types of flanges. A flange is a type of fitting that allows two parts of in a system to be connected together. There are different shapes and types of flanges, each having its own need and demand in the product line. The Stainless Steel Blind Flange is a blind ending flange which is used to terminate a piping line at the end of a connection. There are flanges that need to allow the pipes to go through them and these are called the Stainless Steel Slip On Flange types. They are useful to connect seamless pipes together without damaging the pipes and to hold them tight. The ASTM A182 Stainless Steel Orifice Flanges are usually used in metered connections of fluid where the volumetric flow rate could be calculated. They are often used in pairs and are called the orifice flange union.
Our Stainless Steel Flanges Dimensions range widely with the grade of steel, type of flange and the nominal diameter of the piping system. We offer our customers a range of selection with slip on, blind, weld neck, orifice and other types of flanges. The Stainless Steel Weld Neck Flange Weight is usually higher than the other types because of the additional welded neck which makes the connection stronger but also heavier. The ANSI B16.5 Stainless Steel Spectacle Blind Flange is used for medium radius pipe connection ends. Jignesh Steel is a specialist in flanges and supply all kinds of stainless steel flanges.
