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...
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...
Socket weld flange is similar to the slip-on flange in outline, but the bore is counter bored to accept pipe. Socket welding flanges are typically used on smaller sizes of high pressure pipes. Socket weld flanges are widely used in high pressure systems such as hydraulic equipmenmore...
