Pressure Vessels

  1. How It Works

A pressure vessel is a sealed container designed to hold gases or liquids at a pressure significantly different from the surrounding atmosphere. These vessels work by maintaining internal pressure through robust structural design and material strength. They are engineered to withstand stress from internal pressure while ensuring safe and stable containment. Pressure relief valves, gauges, and safety mechanisms are often integrated to control pressure levels and prevent over-pressurization.

  1. Key Features

  • High Pressure Resistance – Designed to handle low to very high internal pressures
  • Customizable Designs – Vertical, horizontal, cylindrical, or spherical configurations based on application needs
  • Code Compliance – Built to standards like ASME Section VIII, PED, or IS codes
  • Corrosion Protection – Options for internal linings, coatings, or use of corrosion-resistant alloys
  • Safety Systems – Equipped with pressure relief valves, rupture discs, and monitoring instruments

  1. Common Use

Pressure vessels are used in a wide range of industries for storing, processing, or transporting pressurized fluids:

  • Oil & Gas – For gas separation, storage, and process containment
  • Chemical & Petrochemical – Reactors, distillation columns, and storage tanks
  • Power Plants – Boiler drums and steam accumulators
  • Pharmaceutical & Food Processing – For sterile processing under pressure
  • Water Treatment – As filter vessels and pressure tanks

  1. Construction Material

  • Carbon Steel – Cost-effective and strong, used for many industrial applications
  • Stainless Steel (SS304/SS316) – For corrosion resistance in chemical and food industries
  • Alloy Steels – For high-temperature or high-pressure environments
  • Cladded or Lined Vessels – Carbon steel with corrosion-resistant linings (e.g., rubber, PTFE, or stainless steel)
  • Composite Materials – In lightweight applications, such as portable gas cylinders
