Manufacturing of various pressure vessels and storage tanks

Pressure and storage tanks are critical components in various industries, designed to store and contain fluids, gases, and chemicals under pressure. Due to their wide range of applications, these tanks are extensively used in the oil and gas, petrochemical, pharmaceutical, food, and many other industries.

Types of Pressure and Storage Tanks

Pressure and storage tanks come in a variety of forms based on their shape, material, application, and other features. Some of the most common types include:

  • Cylindrical Tanks:
    These are the most commonly used tanks due to their simple design and cost-effectiveness. They are available in various capacities for storing different types of fluids.
  • Spherical Tanks:
    Known for their high pressure resistance, these tanks are typically used for storing high-pressure gases such as oxygen, nitrogen, and hydrogen.
  • Horizontal Tanks:
    Positioned horizontally, these tanks are suitable for storing high-viscosity fluids or solids.
  • Conical Tanks:
    These tanks are used for storing fluids that require phase separation or sediment collection.
  • Double-Walled Tanks:
    These tanks consist of an inner and outer wall with insulation in between. They are ideal for storing hazardous chemicals or temperature-sensitive food materials.

Materials Used in Tank Fabrication

The materials selected for pressure and storage tanks must withstand corrosion, high pressure, and temperature variations. Common materials include:

  • Carbon Steel:
    The most widely used material due to its affordability and good mechanical properties.
  • Stainless Steel:
    Ideal for tanks exposed to corrosive substances, offering excellent durability.
  • Aluminum Alloys:
    Used when lightweight construction and corrosion resistance are critical.

Tank Manufacturing Process

The process of manufacturing pressure and storage tanks includes the following stages:

  • Design:
    Engineers create detailed tank designs based on the project’s requirements.
  • Cutting and Preparing Sheets:
    Metal sheets are cut to the specified dimensions and prepared for welding.
  • Welding:
    The cut pieces are joined together using various welding techniques.
  • Non-Destructive Testing (NDT):
    After welding, the tank undergoes tests such as radiographic, ultrasonic, and magnetic particle inspection to ensure weld quality.
  • Internal and External Coating:
    Protective coatings are applied to the interior and exterior surfaces to prevent corrosion and extend the tank’s service life.
  • Assembly of Auxiliary Equipment:
    Components such as valves, flanges, gauges, and other accessories are installed.

Fabrication Standards

Pressure and storage tanks must be manufactured in accordance with national and international standards. Key standards include:

  • ASME Section VIII:
    Widely used for the design and fabrication of pressure vessels.
  • API 650:
    Commonly used for the design and construction of oil and petroleum storage tanks.
