Stub End Lap Joint Manufacture in India

Stub End -Lap Joint

One of the top producers, exporters, and suppliers of high-quality, high-performance stub end (lap joint) fittings in all major grades and dimensions is Eka Pipe Fittings, with its headquarters located in India. Both standard and non-standard ANSI dimensions are available for stub ends. Eka Pipe Fittings provides an ex-stock supply of alloy steel, nickel alloy, carbon steel, and stainless steel stub ends. On request, lap joints or stub ends of a specific length may also be provided. When rotating back up flanges are desired, stub ends are fittings that are utilized in place of welded flanges. Standard Lap Joint Flanges are the primary application for them.

Stub ends in several grades, including 304/304L, 304H, 316/316L, 321, 347, Duplex steel, 904L, Alloy 20, 317L, and 310S, are manufactured and supplied by us. Power generating, oil and gas, petrochemical, chemical, fabrication and engineering, waste water treatment, and pharmaceutical industries are just a few of the vertical industries for which we sell stainless steel stub ends.
