Stainless Steel Threaded Flange

Stainless Steel Threaded Flange

Carbon Steel Screwed Flanges and BSP/ NPT Threaded Flange manufacturer in India

National Pipe Tapered or the NPT Threaded Flange, has often been referred to as ANSI/ASME B1. 20.1 pipe thread flanges. Since NTP Din 2566 Threaded Flange are not interchangeable, they prove to be an effective seal for those pipes, which are used by our clients in the transportation of hydraulic fluids. A major difference between NTP and bsp threaded flange is the construction of threads tends to differ in a fundamental manner. In the BSP type, or as known in its expanded form is a British Standard Pipe threaded flanges, the peaks as well as the valleys of the threads tend to be rounded.

As opposed to the BSP threaded flanges, the NTP ASME B16.5 Screwed Flanges in which the peaks and valleys of the threads are constructed in a flat manner. More often, our clients who belong to industries like pulp and paper, petroleum, chemicals as well as the petrochemical along with the oil and gas industry use the ANSI 150 Threaded Flange made from varying grades of stainless steel or carbon steel.

Biggest Supplier of Cast Iron Threaded Flange in India, check Inconel 600 Screwed Flanges Chemical and Mechanical Properties

The ansi b16.5 class 150 threaded flanges we produce exhibits excellent performance that has been typically associated with stainless steel such as resistance to corrosion against acids, alkalis and other chemical solutions. Additionally the SS Threaded Flange has the ability to withstand both high temperature and pressure as well. On the other hand if our clients have requirements involving cost efficiency, we suggest the carbon steel threaded flange to be used for their applications as they could be used for demanding applications.
