Learn how to identify and fix frequent issues with sealing tools.

This article covers the ASME standard specification for spiral wound gaskets, including dimensions, materials, construction, and marking requirements as defined in ASME B16.20.

Expanded graphite gaskets are evaluated for their performance in steam systems, considering factors such as temperature resistance, sealing integrity, and potential degradation.

This article describes the distinct designs, pressure capabilities, and typical uses of R, RX, and BX ring joint gaskets, highlighting how each type suits specific flange connection requirements.

Double jacket gaskets consist of a metal outer layer and a soft filler core. Typical metal materials include stainless steel, carbon steel, or Monel, while fillers commonly use graphite, PTFE, or ceramic fiber to ensure reliable sealing in demanding conditions.

For PTFE gaskets, the recommended flange finish is typically a smooth or phonographic finish with a surface roughness of 125 to 250 microinches Ra, as a smoother surface helps prevent cold flow and ensures a reliable seal.
