Pressure Vessels

Shop-fabricated pressure vessels, columns and reactors built to ASME Section VIII, for process, storage and utility applications.

Overview

Pressure vessels are core to our workshop — from design calculation through rolling, welding, NDT and hydrostatic testing. We build new vessels and repair or recertify existing ones already in service.

Scope of Supply

  • Vertical and horizontal pressure vessels
  • Columns, reactors and separators
  • Vessel internals and nozzle fabrication
  • Hydrostatic and pneumatic testing
  • Vessel repair, modification and re-rating

Applications

  • Oil & gas and petrochemical process units
  • Chemical and fertilizer plant
  • LPG and gas processing
  • General industrial compressed-air and utility systems

Manufacturing Process

  1. 1Design review and material procurement
  2. 2Plate rolling, forming and sub-assembly fabrication
  3. 3Welding and in-process inspection
  4. 4Hydrostatic/pneumatic testing
  5. 5Surface treatment and dispatch

Quality & Testing

  • Material traceability from mill certificate through to finished vessel
  • NDT (RT/UT/MT/PT) applied per code and project specification
  • Test and inspection records issued with every vessel

Frequently Asked Questions

Can you fabricate a vessel to a specification issued by our process licensor?+

Yes — we regularly build to third-party and licensor-issued vessel specifications, datasheets and drawings.
