ASME B16.5 Stainless Steel Threaded Flange range from ½ inch to 4 inches in common usage. They have threads which make them be screwed onto the pipe rather than be welded. ASME B16.5 Screwed Flanges can be used in systems where welding is not possible. The threaded Flanges dimensions vary according to the needs but their diameters are usually below NPS 4 standard. Some threaded Flanges pn16 can withstand pressures up to 16 bars. There are different types such as the threaded reducing Flanges which could be used to thread in two pipes of different diameters. The national pipe threaded or npt threaded Flanges are a variation of flanges.

The npt threaded Flanges manufacturer produces them in different capacities. They are also used to thread in PVC pipes. There are different grades such as the threaded flange din 2566. A stainless steel threaded flange can also be welded if the application permits. The welding provides extra sealing of the connection but not necessarily increasing the strength of the connection. This type is called weld on threaded flange and is not common in chemical or oil and gas applications where explosion is a threat.


What is Stainless Steel Threaded Flange?


ASME B16.5 Stainless Steel Threaded Flange Manufacturer in India

reducing threaded flange could be used to connect two pipes of different diameters through the bore to make a joint. There’s a fair deviation of threaded flange price in india due to the supply and demand factors, including the transportation costs and locations. npt threaded flange are common in plumbing applications. Where welding is not a problem and pressures are high, threaded weld neck flange could be used and welded to seal the connection for extra strength and leakage proof. The range of a105 threaded flange is also available in different pressure classes such as ansi 150 threaded flange dimensions. Depending on the need to fit different sizes of pipes together, the reducing threaded flange ASME B16.5 is also used. Their applications include all types of fluid flow systems and hydraulics.
