Pressure Vessels: Industrial and Common Uses


The principle behind the pressure vessel is relatively uncomplicated. Put simply, it is a receptacle that holds gas or liquid at a considerably different pressure than the pressure that exists outside itself. However, the pressure vessel is far more complex, especially once you take into consideration the standards involved in fabricating and maintaining them. With the advances in Alberta’s oil and gas industry, the need for quality pressure vessel fabrication in and around Calgary has been incrementally on the rise. Here at BWS Fabrication Inc., we strive to meet this demand while maintaining the highest levels of safety and performance. Our pressure vessels adhere to strict quality control protocols—procedures that we make available for verification by our clients.



A brief history of pressure vessels

During the industrial revolution, the first pressure vessels were put into use to help power steam engines. However, early technology was unreliable and manufacturing techniques were still in their infancy. A vast number of lethal accidents occurred as a result. In time, this prompted the formation of regulatory boards, which oversaw safety procedures for these devices. These boards are still in place, assuring that 21st century pressure vessels are manufactured under strict safety guidelines.


Pressure vessels today

The majority of modern pressure vessels are constructed from steel with high impact resistance. They have built in safety features including design structures that ensure they’ll leak before bursting. Safety valves are another security component. These guarantee pressure does not exceed key levels.


Uses for pressure vessels off the oil patch

The same technology that you use every day in the field can be found with surprising frequency in the world around you. Here are a few interesting places pressure vessels are found that may surprise you.

  • Propane tanks. Containers that hold chemicals, gases, or pressurized air are all considered pressure vessels.
  • Boilers. These common everyday devices use pressurized heated water to warm homes, drive turbines and more. Because the entire system exists in a closed pressurized loop they can be considered a pressure vessel, depending on their size and pressure rating.
  • Diving cylinders and recompression chambers. Diving cylinders (SCUBA Tanks) with compressed air or gasses qualify as pressurized vessels, as do diving and recompression chambers. Recompression chambers are used to simulate the pressures of the deep ocean and are used in hyperbaric medicine.
  • Submarines. Similar to hyperbaric chambers and diving capsules, Submarines are also pressure vessels.

Pressure vessels in the oil and gas industry

Separating gas and/or oil to meet saleable pipeline specification is critical to the success of your business. The pressure vessels that we produce at BWS Fabrication Inc. are crafted with a commitment to the utmost level of safety and performance. We operate from a culture of quality to deliver high calibre pressure vessels, pressure fittings and other components in and around Calgary, Red Deer, and elsewhere in Alberta—and internationally too.
