ASME B16.11 | Forged Socket Weld Cap | Class 3000–9000 | NPS 1/8–4
Elite is a manufacturer and supplier of high-quality Forged Socket Weld Caps for industrial piping and process applications. These fittings are manufactured using controlled forging and precision-machining processes to provide reliable dimensional accuracy, mechanical strength, and consistent performance.
A Socket Weld Cap is a forged fitting used to close the end of a pipe or piping component. The fitting incorporates a socket-weld connection that allows the pipe to be inserted into the recessed socket and welded in place. Stainless Steel Socket Weld Caps provide excellent corrosion resistance and are widely used in small-bore piping, process systems, instrumentation, chemical service, and other demanding applications.
ASME B16.11 Forged Socket Weld Caps are available in a wide range of sizes, pressure classes, and materials. Elite supplies carbon steel, stainless steel, alloy steel, duplex, super duplex, copper-nickel, nickel alloys, titanium, and other specialty materials according to customer and project requirements.

Standards Note: ASME B16.11 designates socket-weld forged fittings as Class 3000, 6000 and 9000. Class 2000 is a threaded-fitting designation and is therefore not included for socket-weld caps.
The standard size range for ASME B16.11 socket-weld caps extends through NPS 4. Published dimensional references identify socket bore, socket wall thickness, socket depth and end-wall thickness as key cap dimensions.
