Threaded Flanges

The most noteworthy feature of these changes is that they can be joined to a pipe without welding. The bore of Nickel nickel-threaded flanges has threads and can be fitted to pipes that have external threads. Stainless Steel Threaded Flanges are low-priced, the 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 requisites of several industries through our outstanding products and extraordinary services

Socket Weld Flanges

Socket Weld Flanges (SWRF) are counter-bored i.e. the bore of the Flange and pipe, both are the same, thereby providing a good ow 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 industry.

Slip On Flanges

The flange is slipped over the pipe and then welded both inside and outside to provide sufficient strength and prevent leakage. This flange is used in preference to weld necks by many users because of its lower cost and the fact that less accuracy is required when cutting pipe to length.

Weld Neck Flanges

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 contacting WN flange with pipeline or fitting but is preferred for high-stress applications. The necks, or hubs, transmit stresses 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 of the Weld Neck Flange. The bore of the Weld-Neck flange matches the bore of the pipeline, reducing turbulence and erosion.

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 a hub as per the customer’s requirements. We offer blind plate flanges manufactured at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, wastewater treatment plants, paper mills, pharmaceutical plants, and turnkey projects among others.
