Weld neck flanges are connected to pipe by welding the pipe to the neck of the 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 flanges. Weld neck pipe flanges are more...
Threaded flanges are widely used in low pressure piping system. There is no welding involved while connecting the flanges to pipes or other equipment. Sometimes the flange may be welded around the joint after assembly, but it is not considered a satisfactory method of increasing more...
Slip-on flange usually slips over the pipe. Slip-on flange are typically made with an inside diameter of flange slightly larger than the outside diameter of the pipe. This allows the slip on flange to slip over the pipe. Slip-on flanges are welded to provide strength and prevent more...
