This article provides a step-by-step guide to correctly installing an expanded graphite gasket, covering surface preparation, handling precautions, and proper bolt-tightening procedures to achieve a reliable, leak-free seal.

The required surface finish for flanges using ring joint gaskets is typically a smooth machined finish, often with a roughness average (Ra) of 3.2 µm (125 µin) or finer, as specified by standards like ASME B16.5, to ensure proper sealing by allowing the gasket to deform and fill imperfections without leakage.

Double jacket gaskets often maintain reliable sealing under thermal cycling due to their metal construction and resilient filler, but performance depends on factors such as material compatibility, flange alignment, and cycle severity. Thermal expansion and contraction can reduce residual bolt load over time, potentially leading to leakage if not properly managed.
