Stainless Steel Threaded Flanges
Threaded Pipe Flanges and Carbon Steel Threaded Flanges Manufacturer in India
Stainless threaded flanges are available in the market as these are in high demand and are thus manufactured by every steel company. There are various dimensions of this and the factors which it consists are outside diameter, minimum thickness, overall welding, lap joint length and many more. Based on this the product is manufactured. SS threaded flanges are similar to slip on flanges and are used in applications like piping systems and low pressure.
Low pressure iron and steel threaded pipe flanges are used in non-corrosive environments and the corrosion resistance of this is excellent. It is used in plumbing, air and natural gas. These are suited for low to medium pressure applications. This comes in different styles, shapes and sizes. Threaded pipe flanges are the special type of flanges that are attached to the pipe without welding. This doesn’t require any welding and many other chemical solutions are used. Threaded reducing flanges includes weld-neck reducing flanges, slip on reducing flanges and many more.
These are the flanges with one specified diameter having a bore of different and smaller diameter. These are the flanges which are available in various types and applications like plumbing, water supply systems, fabrication industry, food processing industry and lot more. Threaded stainless steel flanges are the one which is manufactured by Regal Sales Corporation. We are the one where we are ISO certified and 20 years old organization. We use high quality raw materials to manufacture this product.
