ASME/ANSI B16.5 PLATE FLANGES (SLIP-ON) MANUFACTURER IN INDIA MANUFACTURER/EXPORTER OF HIGH QUALITY PLATE SLIP-ON FLANGES CARBON, ALLOY, STAINLESS STEEL PLATE FLANGES
Prakash Metal Corporation is a leading manufacturer, exporter and supplier of stainless steel bends, carbon steel bends, and alloy steel bends in a complete range of radius and diameters. Steel pipe bends can be manufactured from a wide range of pipe materials – including low and high yield carbon steels, alloy steels, stainless steels, Cr-Ni alloys and titanium. We specialise in the manufacture of large and small size stainless steel bends and piggable bends in grades Duplex, 310S, 304L, 316L, 317L, 347, 321, 904L.
The lap joint flange with the stub end assembly is normally used in piping systems which require regular dismantling for inspection and cleaning. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End).
Stainless steel plate flanges are manufactured from plated produced in accordance to the ASTM A240 and ASME SA240 standards. Plate flanges are widely accepted as an alternative to cast or forged flanges in low pressure applications because of the benefits listed below.
Plate flanges are most widely used in fuel and water pipelines, where two flange plates are bolted together with a gasket in between them. The flange plate will have bolt holes all around the perimeter and will be used to create junctions, tees and joints.
