Ramesh Steel Flanges suppliers - The threaded flange dimensions and weights according to the EN 1092-1 type 13 specification for steel flanges manufactured in the European Union. Ramesh Steel is India based company, a largely diversified flanges manufacturer company in india, A majority of our business originates from the India, Ramesh Steel has the capability to manufacture Flanges for all pressure ratings including 75#, 125#, 150#, 175#, 250#, 300#, 350#, 400#, 600#, 900#, 1500#, and 2500#.

THREADED PIPE FLANGES

Threaded pipe flanges are similar to slip-on pipe flanges except the bore of threaded pipe flange has tapered threads. Threaded pipe flanges are used with pipes that have external threads. The benefit of these pipe flanges is that it can be attached without welding. Threaded pipe flanges are often used for small diameter, high pressure requirements. Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 24". Ramesh Steel provides Slip-On pipe flanges in all material grades, specifications and sizes.

Threaded pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for threaded pipe flanges, the standard height is 1/16" for threaded pipe flanges under 400#. For threaded pipe flanges of 400# and up, the standard threaded pipe flange raised face height is 1/4".

Ramesh Steel manufactures threaded pipe flanges in all steel material grades, including carbon threaded pipe flanges, stainless steel threaded pipe flanges and alloy threaded pipe flanges. Ramesh Steel also has many different threaded pipe flanges in stock and ready to ship.

Threaded Flanges

Our range of threaded flanges and NPT flanges are manufactured as per international quality standards and is available in various dimensions. Our threaded flanges are used with their main advantage being that they can be used for extraordinary circumstances and in highly volatile areas where welding is hazardous. Our NPT threaded flanges can attached to the pipe without welding. These are low maintenance threaded flanges made from high quality raw material, that are available at fair prices. We ensure timely delivery of the products within stipulated time frame.
