Pressure Vessel

A pressure-retaining container designed to hold fluids at pressures substantially different from ambient pressure.

Definition

A Pressure Vessel is a container designed and constructed to contain liquids or gases at pressures significantly above or below atmospheric pressure. Pressure vessels are designed in accordance with recognized engineering codes and standards to safely withstand internal or external pressure, temperature and associated mechanical loads throughout their intended service life.

Why It Matters

Pressure Vessels are engineered pressure-retaining components designed for the safe containment of pressurized fluids.

In Practice

Pressure vessels include equipment such as separators, reactors, drums, heat exchangers and accumulators and are subject to inspection, maintenance and regulatory requirements throughout their operational life.

Common Misuse

A Pressure Vessel is a pressure-retaining component designed to contain pressurized fluids, whereas Pressure Relief Valves protect pressure vessels from excessive internal pressure.
