Weld neck pipe flanges are connected to the pipe by welding the pipe to the neck of the pipe flange, which helps to pass on the stress from the weld neck to the pipe itself. This also reduces high stress concentration at the base of the hub of the weld neck pipe flanges. Weld neck pipe flanges are generally used in high pressure applications, where hot or cold temperatures exist. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe
