Weld Neck Flanges
Our weld neck flanges provide superior structural integrity and stress distribution for high-pressure and high-temperature piping systems. Featuring a tapered hub design that transitions smoothly into the pipe wall, these stainless steel flanges minimize stress concentration at the weld joint. Manufactured in SS304, SS316L, and carbon/alloy steel grades, they comply with ANSI, GB, and DIN standards with PN16–PN40 ratings. Ideal for oil & gas, chemical, and power plant applications, each weld neck flange delivers reliable performance under cyclic loading and thermal expansion.
