The pipe is inserted into a socket end and secured with a single fillet weld around the hub, offering a smooth bore and reducing turbulence. Stainless steel socket weld flanges are ideal for piping systems requiring strong structural integrity, especially where internal welding is difficult. Available in sizes from DN15 to DN3000 and compatible with ANSI, EN, and JIS standards.<\/p>\n<h3 data-start=\"759\" data-end=\"786\"><strong data-start=\"763\" data-end=\"784\">Application
