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 its applications. Threaded flanges are also known as screwed flanges and are similar to slip-on flanges, but the bore is threaded to enable assembling without welding. Threaded flanges are usually used with pipes that have external threads. Threaded flanges are widely being used in shipbuilding, power generation, petrochemical plant, water treatment, dairy plant, pharmaceutical plant etc.

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 equipment and steam lines. Socket weld flanges are attached by inserting the pipe in to the socket end and then applying fillet weld around the hub of the flange. This allows for a smooth bore and batter flow of the fluid inside the pipe. An optional internal weld may be applied in high stress applications. Socket weld flanges are widely being used in shipbuilding, power generation, petrochemical plant, water treatment, dairy plant, pharmaceutical plant etc.

Normally referred as blanking flanges, Blind flanges are widely used in high pressure applications. Blind flanges are generally used to seal the end of the piping system to prevent flow of fluid. The use of blind flanges allows easy of access to piping system once it has been closed. Blind flanges are widely being used in shipbuilding, power generation, petrochemical plant, water treatment, dairy plant, pharmaceutical plant etc.

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 generally used in high pressure application, 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. Weld neck flanges are widely being used in shipbuilding, power generation, petrochemical plant, water treatment, dairy plant, pharmaceutical plant etc.

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 leakage. Slip-on flange can sometime also have a boss /ring or hub and can be made with a bore to suit either pipe or tube. Ring pipe flanges and hub pipe flanges are both considered slip-on flanges as they both slip over pipe. Slip-on flanges are generally preferred by users over weld neck flanges, as they are cheaper option than weld neck flange and the fact that less accuracy is required when cutting pipe to length. Slip-on flanges are widely being used in shipbuilding, power generation, petrochemical plant, water treatment, dairy plant, pharmaceutical plant etc.

Lap joint flanges are similar to other type of flanges, but it does not have a raised face. Lap joint flanges are used in conjunction with a "Lap Joint Stub End". The total initial cost of a lap joint flange along with a stub end is around one third higher than that of comparable welding neck flanges. The pressure handling capacity of lap joint flange is cooperatively lower, and the fatigue life for the assembly is only one tenth that of welding neck flange. The lap joint flange with stub end assembly is used in piping systems which require regular dismantling for inspection and cleaning. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe stub end. Lap joint flanges are widely being used in shipbuilding, power generation, petrochemical plant, water treatment, dairy plant, pharmaceutical plant etc.
