Flanges made up of various materials and of various types are available in the market. One such type is the Threaded Flange. Special circumstances demand the use of these BSP Flanges since they can be attached to the pipe without welding. Threaded Pipe Flanges at times can be welded if the circumstance demand so. Aluminum Threaded Flange is not suitable for walls that have thin thickness. Therefore thicker wall size needs to be chosen for fitting Small Screwed Flanges. The question that arises is what is the ideal thickness of the wall?

Well, Male And Female Threaded Flange belonging to schedule 80 of ASME B36.10 are said to have ideal thickness. Flat Face Flange is similar to slip on flanges however, the major difference between them is that High Pressure Threaded Flange is bored to meet the diameter of a particular pipe in the inner side. Threaded Floor Flange is used in the piping system where it is not possible to weld a flange. This includes the use of 2/ 3/ 4 Inch Threaded Flange in an explosive location where welding might develop potential risk. Galvanized and cast pipes are usually used with these Raised Face Threaded Flange.

This is because it is fixed on to a pipe that has an additional thread on the tapered end of the pipe. ANSI Class 150 Threaded Flanges can also be welded if required to provide a tighter seal. Ring Type Joint Flange can also be threaded depending upon the requirement of the application. PN16 Screwed Flanges are used mostly in aircraft. Low-pressure iron and steel Polished NPT Flange are used in corrosive, as well as non-corrosive environments.

Carbon Steel Screwed Flanges are used in natural gas, plumbing, and air supply equipment. They are said to be suited for low and medium-pressure applications. We have been supplying these to our customers for generations now and our excellent quality and pocket friendly prices have made us the leading Stainless Steel Threaded Flange Manufacturer In India.
