We are offering slip on flange. A slip on flange is slightly larger than the outer diameter of the pipe it is to be used with. The pipe is slipped into the flange prior to welding both inside and outside. High quality slip on flanges are ideal for lower pressure applications. The slip on flange's ease of fitting and welding also reduces fabrication costs.

We are offering threaded flange. A threaded flange is usually confined to a special application. The main benefit of a threaded flange is that it can be assembled without welding which makes it perfect for extremely high pressure services. Sometimes a seal weld is also used in conjunction with the threaded connection of the flange. A threaded flange is unsuited for conditions involving temperature or bending stresses of any magnitude. Particularly under cyclic conditions where leakage through the threads may occur in relatively few cycles of heating or stress.

We are offering socket weld flange. A socket weld flange is similar to a slip on flange, however socket weld flanges have an internal recess on the inside diameter to allow for a smoother flow of the process fluid. This creates a smooth bore with the proper welding and grinding. However a socket weld flange can be more expensive than a slip on flange due to the more intricate machining. Socket weld flanges were initially developed for use on smaller sizes of pipe at higher pressure ratings.

We are offering weld neck a weld neck flange is drilled with the wall thickness of the flange having equal dimensions to the matching pipe. The lighter the pipe is the larger the bore is in the weld neck flange. And conversely the heavier the pipe is the smaller the bore is in the weld neck flange. Weld neck flanges are usually used in high pressure systems and are suitable for cold or hot temperatures.

We are offering lap joint flange.a lap joint flange is usually used in conjunction with lap joint stubs. Lap joint flanges in carbon or low alloy steel piping systems are best used when frequent dismantling for inspection and cleaning is required. The use of lap joint flanges at points where severe bending stress occurs should be avoided.

We are offering customized flanges. Penta auto forge can also provide fully customized bespoke flanges to client drawings, calculations can be supplied on request. If you have a special requirement please contact us with details of your needs for more information, calculations or quotes.
