The GA05-4 slip-on welding flange is the industry-standard component for fabricating flanged steel pipe sections. This type of flange slides over the end of the pipe and is fixed with two weld beads (one inside and one outside), creating a solid, integral, permanent connection that offers great structural safety.
It is the preferred solution in workshops and on site for fabricating made-to-measure spools and for building pipe networks requiring maximum reliability. Being made of weldable carbon steel, it becomes part of the pipe itself, guaranteeing excellent performance under pressure and mechanical stress.
Compliance with the DIN 2576/2502 (EN 1092-1) dimensional standards ensures perfect alignment and compatibility with the rest of the valves, pumps and flanged equipment in the system.
