ASME/ANSI B16.5 LAP JOINT PIPE FLANGES MANUFACTURER IN INDIA MANUFACTURER/EXPORTER OF HIGH QUALITY LAP JOINT (LJ) FORGED FLANGES CARBON, ALLOY, STAINLESS STEEL LAP JOINT FLANGES
Texmo Alloys 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).
Lap Joint Flanges are similar to other types of industrial flanges, but it does not have a raised face. Lap joint flanges are used in conjunction with a “Lap Joint Stub End”. The total initial cost of a lap joint flange along with a stub end is around one-third higher than that of comparable welding neck flanges. The pressure holding capacity of lap joint flanges is comparatively lower, and the fatigue life for the assembly is only one tenth that of welding neck flanges.
We offer lap joint flanges manufactured at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants and turnkey projects among others.

Quality Assurance
all fittings and flanges are subject to strict inspection at each stage of the production process, from starting material purchasing to product dispatch. They are visually examined for conformity to ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, official certified Inspection Agencies can be called in to witness the material reports, dimensions and quality conformity of products.
Marking & Packing
Products are packaged to ensure that there is no damage during transit. In case of exports, standard export packaging is done in wooden cases. All elbow fittings are marked with Grade, Lot No, Size, Degree and our trade mark. On special requests we can also, make custom marking on our products.
