Flange Gaskets for PN16/PN25/PN64-DI/CI/MS Pipe
The medium used in the middle of the pipe connection is a ring made of a material that produces plastic deformation and has a certain strength. Most of the gaskets are cut from non-metallic plates or made by professional factories in the specified size.
The gasket materials should be chemically and thermally compatible with the internal fluid and the external environment, and should be of appropriate hardness, thickness, and style. Elevated temperature applications may require higher temperature capability. Gasket materials are not limited to those shown in Table 22. Other materials may also be suitable.
Gasket thickness should be about 1/8"-3/16" (3-5 mm), and about 55-75 durometer Type A hardness per ASTM D2240.
Too soft or too thick gaskets may blow out under pressure. Overly hard gaskets may not seal
One of the many areas that R.S.L. Gasket has developed an expertise in is flange gaskets. Whether it is a custom or standard flange gasket, ring gasket, or full face gasket, R.S.L. Gasket has the extensive in-stock inventory and knowledgeable engineering and production staff to produce the specific custom gasket or custom seal that is needed.
In its simplest form, a flange gasket is used to join or fit between two sections of pipe; each pipe section typically has a flared area that provides a surface for the gasket to attach to. Types of flange gaskets include ring gaskets and full face gaskets.
A ring gasket is a gasket with an inner diameter (ID) and outer diameter (OD);
A full face flange gasket is similar to a ring gasket, with bolt holes (aligned in a bolt circle) in the surface area between the ID and OD.
Both ring gaskets and full face gaskets come in metric and standard sizes, and in various thicknesses. R.S.L. Gasket specializes in the fabrication and production of custom flange gaskets, ring gaskets, and full face gaskets.
