A Socket Weld (SW) Elbow is a forged high-pressure pipe fitting designed to change the flow direction in small-bore piping systems. Its core connection method involves inserting the pipe end into a recessed socket on the elbow, followed by a fillet seal weld at the outer joint, complying with the widely adopted ASME B16.11 standard (forged socket-weld/threaded fittings). 1.Types & ConfigurationsAngle Options: The most common are 45° and 90° elbows; 180° return bends are also available for specific loop applications.
2.Radius: Typically short radius (R=1.0D) and long radius (R=1.5D), with long radius being the default for lower pressure drop. 3.Size Range: Primarily for small diameters, usually NPS ¼ to NPS 2 (DN 6–50); larger sizes are rare as SW is inefficient vs. butt-weld. 4.Pressure Ratings: Class 2000, 3000, 6000 (high-pressure service).

Product Description
Incoloy 840 Introduction
Monel 400 alloy (UNS N04400/MCu-28-1.5-1.8/Ni68Cu28Fe) is a nickel-based alloy, primarily composed of nickel-copper alloy, with a melting point of 1300-1350°C. It exhibits good corrosion resistance in corrosive media such as seawater, hydrofluoric acid, and sulfuric acid. This alloy demonstrates stable mechanical properties and is suitable for working environments ranging from low to high temperatures. Welding can be performed using TIG, MIG, and manual arc welding, matched with Monel body material or EniCu-7welding consumables. This alloy is mainly used in the manufacture of heat exchange equipment, chemical pipelines, reaction vessels, and other devices, conforming to standards including ASTM B 164 (bars) and ASTM B 127 (plates). During machining,shrinkage allowance must be allowed to ensure dimensional accuracy. This can be achieved through traditional machining methods; however, high-speed machining requires the use of water coolant.
