Two core mechanisms: Plastic deformation (coining) – Bolt preload compresses the gasket, causing controlled local plastic deformation (not full permanent

ASME B16.20 covers dimensions, tolerances, materials, and marking for metallic gaskets used with ASME B16.5 and B16.47 flanges. It includes

Both are ASME B16.20 R‑type gaskets with the same R numbers. Their key differences lie in cross‑section geometry. Oval type

ASME B16.20 defines three core RTJ gasket designs for high-pressure sealing services. R type – The conventional basic design, suitable

An RTJ (Ring Type Joint) gasket is a solid metallic sealing ring with precision machining, mainly used in high-pressure and

Metal ring gaskets can be classified into two types: octagonal gaskets and oval gaskets. The primary difference between these two

1. Before installation, the sealing surfaces of the metal ring gasket and flange should be cleaned thoroughly, and any defects

Octagonal gasket is a type of metal ring gasket, and there is also another type, elliptical gasket. Octagonal gasket sealing

When manufacturing metal ring gaskets, material selection, dimensional specifications, and tolerance control need to be considered. The specific requirements are
