Weld Neck Flanges

A weld neck flange is a flange that is designed to be joined to a piping system by butt welding. This kind of flange includes lots of specifications. Weld Neck Flange is expensive because of its long neck and the cost of people to contact WN flange with pipeline or fitting, but it is preferred for high-stress applications. The necks, or hubs, transmit stress to the pipeline. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement for the weld neck flange. The bore of the Weld-Neck flange matches the bore of the pipeline, reducing turbulence and erosion.

Long Weld Neck Flanges

Weld neck flanges in hard-to-find metals. Long weld neck flanges have a hub that extends from the flanges at the surface, which helps in accommodating the pipe more easily. Alloy Steel Long Weld Neck Flange falls under the group of specialty flanges, reinforcement in services at higher temperatures in the oil industry. Carbon steel long welding neck flanges are preferred in the petroleum and chemical industries as they operate under actuating temperature ranges.

Slip On Flanges

Slip-on Flanges have bored with a diameter slightly larger than the pipe; this helps them slide over the pipe. This ANSI B16.5 SORF flange is then welded inside and outside too, with fillet welding. Alloy steel slip-on plate flanges are thinner compared to other ranges, cost-effective, and easy to use in fabricated applications. We supply carbon steel slip-on raised face flanges in both raised face and at-face designs to industries like agriculture, fertilizers, pharmaceuticals, textiles, and general engineering purposes.

Socket Weld Flanges

Socket Weld Flanges (SWRF) are counter-bored, i.e., the bore of the flange and pipe are the same, thereby providing a good flow of the product through the pipe. Initially used for small-sized high-pressure pipes, our SMO 254 socket weld flanges are now used in high-pressure systems too. Our stainless steel socket weld flanges are oxidation-resistant and promote better weldability and fabricability. We seek to offer ANSI B16.5 Carbon Steel Socket Weld Flanges that have excellent stress corrosion cracking resistance to the LNG, seawater, and mining industries.

Threaded Flanges

The most noteworthy feature of these changes is that they can be joined to a pipe without welding. The bore of nickel-threaded flanges has threads and can be fitted to pipes that have external threads. Stainless steel threaded flanges are low-priced,  best for small pipes, and can be used in low-pressure applications. They are very beneficial in highly combustible industries where welding is dangerous. We are certified to cater to the challenging requirements of a number of industries through our outstanding products and extraordinary services.

Blind Flanges

Commonly referred to as blanking flanges, blind pipe flanges are widely used in high-pressure applications. Blind flanges are generally used to seal the end of a piping system to prevent the flow of liquids or gases. The use of blind flanges allows ease of access to a piping system once it has been closed. Our blind flanges are available with raised or RTJ faces and also with female threads. Blind flanges can be supplied with or without hubs as per customer requirements. We offer blind plate flanges manufactured at our facility to companies in various industries, including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants, and turnkey projects, among others.

Lap Flanges

Lap flanges are used with a stub end, which is welded to the pipe. Alloy Steel Lapped Flanges are designed in such a way that they swing over the pipe without the need to be welded. As they do not come into contact with the inner fluid, they do not corrode and can be re-used. Our ANSI B16.5 stainless steel flanges are inexpensive and widely useful. In addition, they can be easily assembled and dismantled for a quick inspection.
