Pressure Vessels

A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.

Pressure vessels can be dangerous, and fatal accidents have occurred in the history of their development and operation. Consequently, pressure vessel design, manufacture, and operation are regulated by engineering authorities backed by legislation. For these reasons, the definition of a pressure vessel varies from country to country.

Design involves parameters such as maximum safe operating pressure and temperature, safety factor, corrosion allowance and minimum design temperature (for brittle fracture). Construction is tested using non-destructive testing, such as ultrasonic testing, radiography and pressure tests.

Hydrostatic tests use water, but pneumatic tests use air or another gas. Hydrostatic testing is preferred, because it is a safer method, much less energy is released if a fracture occurs during the test (water does not rapidly increase its volume when rapid depressurization occurs, unlike gases like air, which fail explosively).

We manufacture various types of pressure vessels, custom made for a wide range of applications. This includes Reactor, Columns, Ammonia Vessels, Pressure Vessels, Tanks, Oil Pots, Scrubbers as well as repair work (both on- and off-site).

Our equipment is fabricated in adherence and strict conformance to national and international codes of design.

Accreditation includes the following:

  • ISO 9001:2015
  • ISO 3834 Part 2 & ASME Section VIII Division 1 Appendix 10
