What is a Pressure Vessel?

A pressure vessel is a container designed to hold gases or liquids at a pressure significantly different from ambient conditions. Due to the inherent risk involved with pressure containment, their design requires strict adherence to codes and safety standards.

Applications include:

  • Heat Exchangers

  • Reactors

  • Air Receivers & Separators

  • Storage Tanks

  • Boilers

  • Columns & Towers

Industries We Serve

  • Oil & Gas

  • Petrochemical & Chemical Processing

  • Power Generation (Thermal, Nuclear, Renewables)

  • Pharmaceutical Manufacturing

  • Food & Beverage Processing

  • Water & Wastewater Treatment

  • Marine & Offshore

    • Nozzle and manway design

    • Head types (ellipsoidal, hemispherical, torispherical, Flat Head)

    • Design of stiffeners, skirts, and supports

    • Wind and seismic load evaluations

  • For high-temperature, high-pressure, or critical service vessels, we perform detailed analysis to ensure structural integrity:

    • Thermal stress evaluations

    • Local stress checks at nozzles and openings

    • Finite Element Analysis (FEA)

    • Load combinations (pressure, dead weight, thermal, seismic)

  • We provide fabrication-ready documentation with precision 2D and 3D detailing:

    • General Arrangement (GA) drawings

    • Shell, head, and nozzle detailing

    • Welding symbols and fabrication notes

    • Bill of materials (BOM) and part numbering

    • Lifting lug and support structure design

    • 3D modeling for clash checking and integration
