ASME Pressure Vessels
Time to Read: 2m 48s
A pressure vessel is a entirely closed container designed to hold liquids or gases at a higher or lower pressure than the ambient pressure. ASME pressure vessels refers to the US design and operating standards for pressure vessels. The theoretical ideal shape of a pressure vessel (for greatest strength) is a sphere; however, due to the engineering complexities involved, most ASME pressure vessels take the form of a metal cylinder closed with convex endcaps. Pressure vessels must be welded to produce a secure enclosure that can withstand the pressure differential, and the welding or pressure vessels is governed by ASME standards as well.
Manufacturers of ASME Pressure Vessels
- Anderson Dahlen is a US-based manufacturer of custom fabricated ASME Pressure Vessels for the food, dairy, beverage, and pharmaceutical industries. Anderson Dahlen can fabricate pressure vessels with ASME section VIII division 1 certification as well as dimple heat transfer jacketed tanks with ASME section VIII division 1 certification.
Pressure Vessel Safety and GovernanceThe contents of pressure vessels are often under enormous pressures, and failure of the pressure vessel could result in an explosion-like decompression. As a result of the high safety hazard of pressure vessels, they are goverened by strict safety regulations that are backed by legislation -- so the safety regulations carry with them the force of law. Within the US, the ASME regulations govern the safe design and operation of pressure vessels. Specifically, the following ASME sections apply:
- ASME Code Section VIII Division 1: US standard, design by formula. Division 1 is the standard ASME pressure vessel regulation used throughout the US and widely adopted worldwide.
- ASME Code Section VIII Division 2: Alternative Rules, design by analysis.
- ASME Code Section VIII Division 3: Alternative Rules for Construction of High Pressure Vessel
