Carbon steel Threaded Flange
Dinesh Industries is a specialised manufacturer of high quality ASME/ANSI/DIN standard threaded flanges or screwed flanges in India. We offer immediate delivery programs for standard size of carbon steel threaded flanges and stainless steel threaded flanges.Threaded flanges are widely demanded as pipe flanges used in different industrial applications. They are the special type of pipe flanges which can be attached to the pipe without welding. Threaded flanges are threaded in the bore which matches an external thread on the pipe. These threads are tapered in order to create a seal between the threaded flange and the pipe as the tapers approach the same diameter. Sometimes a seal weld is also used together with the threaded connection. They are available in various sizes and materials.
We offer threaded pipe 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 other
