Pressure vessels play an important part in any project in the oil and gas sector. However, poorly designed pressure vessels can be dangerous, even fatal, to workers. At Moss Fabrication Ltd., our over three decades of industry experience allows us to confidently fabricate custom pressure tanks and pressure vessels in Calgary. We are also ASME certified for pressure vessel and tank design and fabrication.

Our pressure tanks are designed, engineered, and constructed to fit our customers’ specifications and purpose of use. Using the knowledge and skill we have accumulated over the years, our pressure vessels manufacturers have the expertise to fabricate simple and complex vessels, large and small ones, and even vessels with unusual shapes, temperature requirements, and multiple chambers.

Contact us today to learn more about our pressure vessel and tanks fabrication work in Calgary. A service representative would be happy to discuss with you your unique fabrication requirements.


Depending on their purpose, pressure vessels come in many shapes, forms, and materials. For example, vessels can be spherical, cylindrical, and even rectangular. However, more unusual shapes may be more expensive to manufacture as they are more difficult to engineer.

Materials used in pressure vessel fabrication include steel, composite materials, polymers, and even concrete. Carbon fibre vessels can be extremely light but more difficult to construct.
