ansi round id 2inch welding stainiless tri clamp stainless steel 304 ferrule flange pipe

Weld flange holes are machined to match the ID of the pipe or fitting. This creates a smooth transition between weld neck flanges and prevents turbulence at the weld neck. Therefore, it is important to specify a piping plan when purchasing butt weld flanges. Butt weld flanges are welded to the pipe with a full penetration weld and provide excellent stress distribution through the tapered neck. In critical applications, welds are also often radiographically or UT inspected.
