How to exploit the less rigid flat welding flange?
Dec 16, 2016

Flange gasket is a plastic deformation, and rings made of material with a certain intensity. Most non-metallic plate flange gaskets from cutting down, or by professional factory made according to the required size, the material is asbestos, asbestos Board, polyethylene boards,; also useful for thin sheet metal (Tin, stainless steel) will be made of non-metallic materials such as asbestos encased metal gaskets.

The less rigid flat welding flange, apply pressure p ≤ 4MPa; welding neck flanges, also known high-neck flanges, rigidity, suitable for high pressure and temperature. Flange sealing surfaces-there are three: flat sealing surface, suitable for high pressure, medium-toxic; embossing seal, suitable for high pressure situations; sealing surface of tongue and Groove, suitable for inflammable, explosive and toxic media and high pressure situations.

Spacer is a plastic deformation, and rings made of material with a certain intensity. Most non-metallic plate gasket from cutting down, or by professional factory made according to the required size, the material is asbestos, asbestos Board, polyethylene boards,; also useful for thin sheet metal (Tin, stainless steel) will be made of non-metallic materials such as asbestos encased metal gaskets.

There is a thin steel band together with asbestos tape wound into a spiral wound gaskets. Rubber gaskets suitable for temperatures below 120 degrees; asbestos rubber gasket is suitable for steam temperature lower than 450 ℃, the oil temperature below 350 ° c, pressure of 5MPa, for General corrosive, the most commonly used are acid-resistant asbestos rubber sheet. According to the mating parts can be divided into the container flange and the flange. By structural type, with integral flanges, flanged and threaded flanges. Overall falanyouping of common welding flange and the flange.

It can be formed by the cast (n/a), it may be threaded or welded. Flange connection (flange,joint) consists of a pair of flanges, several bolts and a gasket nut. Gasket placed between the two flange sealing surface, tighten the nuts, gasket pressure reaches a certain value on the surface deformation, and filled up on the sealing surface uneven, joining close not leak. Flange connection is a detachable joints.
