ASME B16.11 Socket Welding Couplings

2023-12-04 16:25:02 Hits:155 American Standards / Product Standards

ASME B16.11 socket welding couplings are fittings designed for use in high-pressure piping systems using the socket welding connection method.The size range of ASME B16.11 socket welding couplings varies to accommodate different pipe diameters. ASME B16.11 sleeve welded couplings can be divided into half coupling and full coupling.Half couplings and full couplings designed according to ASME B16.11 are suitable for applications where high-pressure and high-temperature conditions are prevalent. Industries such as oil and gas, petrochemical, power generation, and chemical processing commonly use these couplings.

Haihao Group manufacture socket welding couplings according to ASME B16.11 standard in the nominal pipe size ⅛ through 4. ASME B16.11 socket welding couplings are available in different pressure classes, such as 3000, 6000, and 9000.The materials can be carbon steel,stainless steel,alloy steel and so on.The dimensions of socket welding couplings according to ASME B16.11 standard as follows:
