Pressure Vessels to Infinity and Beyond

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure Vessels to Infinity and Beyond

Well, maybe not quite that far. As noted in an earlier Put the Pressure on Us blog, a pressure vessel is a storage tank or vessel that has been designed to operate at pressures above 15 psig. The Office of Safety and Mission Assurance Division of National Aeronautics and Space Administration (NASA) reports that there are approximately 10,000 ground-based Pressure Vessels and Systems (PVS) across the agency.

However, there are out of this world applications, too. One example is the pressure vessel built for the crew compartment of the Orion spacecraft. In this pressure vessel, flight crews will live and operate the spacecraft on flights from the Earth to cislunar (within the Moon’s orbit) space and back. While the vacuum of space exists outside of the vessel, an earthlike 15 psia pressure must be monitored and controlled inside to support the crew.

In contrast, an unpressurized lunar rover is being pursued as part of NASA’s project to land the first woman and the next man on the Moon by 2024. In this case, the astronauts’ suit will regulate the pressure the aliens from earth will need to survive.

Pressure Vessels

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure Vessels

Industrial pressure vessels, essential to the continual processing and manufacturing by industrial and commercial enterprises, have three common types: storage vessels, heat exchangers and process vessels. In general, a pressure vessel is a storage tank or vessel that has been designed to operate at pressures above 15 psig. The pressure can be either internal or external.

According to the report “Pressure Vessel – Global Market Outlook (2019-2027),” the Global Pressure Vessel Market accounted for $40.85 billion in 2019 and is expected to reach $67.6 billion by 2027, growing at a compound annual growth rate (CAGR) of 6.5% during the forecast period.

In addition to industrial and commercial applications, there are many government pressure vessels as well. For example, the Office of Safety and Mission Assurance Division of U.S. National Aeronautics and Space Administration (NASA) reports that there are approximately 10,000 ground-based Pressure Vessels and Systems (PVS) across the agency.

The pressures contained by these vessels can vary considerably. As a result, the NASA standard “NASA Requirements for Ground-Based Pressure Vessels and Pressurized Systems (PVS)” (NASA-STD-8719.17, Revision: C, Dated 2017-08-09) specifically includes systems often referred to as “low pressure” such as building and facility services equipment (such as shop air), laboratory systems and vacuum systems. To cope with the wide range of pressures, the sensors and measuring systems to monitor and control these vessels can vary widely as well.
