Stainless Steel Lap Joint Flange Manufacturers produce a variety of lap-joint flanges for use in different systems. The flanges belonging to the lap joint Flanges ANSI B16.5 group range from ½ inch to 24 inches in diameter. They can come with a flat face as lap joint flange flat face or with a raised face as the lap joint Flanges raised face. There are different styles such as the lap joint flange rf type with the raised face, rtj lap joint flange which has the ring type joint, and different pressure classes such as the lap joint flange class 150 or the lap joint flange pn10 which can hold up to 10 bars of pressure.

carbon steel lap joint Flanges are usually within the lap joint flange b16.5 class which are up to NPS 24 specification. ASME B16.5 Lap Joint Flanges are an assembly of two components. There is a stub end that acts more like a welded neck but is not readily welded. The most preference is in the harder to align pipe systems because the stub end makes it easy to align the bolt holes because of the lap joint stub end Flanges. The series of lap joint flange EN 1092 1 can have flanges ranging from PN2 through PN400. Lap joint pipe Flanges can also be welded to make sure that the connection is sealed.


What is Stainless Steel Lap Joint Flange?


ASME B16.5 Stainless Steel Lap Joint Flange Manufacturer in India

lap joint weld flange is not common however because these are usually applied in system which require regular dismantling. Rf lap joint flange helps the alignment much easier and the sealing much stronger due to the raised face. In connections where air tight sealing is required, the lap joint flange rtj with the gasket in the middle is used. There are special classes with specific pressure requirements such as lap-joint flange uni 6090 which is in the PN16 range.

ASME B16.5 Stainless Steel Lap Joint Flange And Copper Nickel Lap Joint Flange slide directly over the pipe and are most mostly used with stub end fittings. ASME B16.5 Aluminum Lap Joint Flange is having two components, a loose backing flanges, and a stub end flanges. Lap Joint Backing Flange freely move over the pipe and Stub end is butt welded to the pipe. Carbon Steel Lap Joint Backing Flange can be of different material than stub material and normally of the carbon steel to save the price.
