  2. TANKS AND VESSELS

Concept

Storage tanks containing organic liquids, non organic liquids, vapors and can be found in many industries. Most storage tanks are designed and built according ASME SEC VIII, API-650 standard specifications. These tanks can have different sizes, ranging from 2 to 60 m diameter or more. They are generally installed inside containment basins in order to contain spills in case of rupture of the tank. Industries where storage tanks can be found are: petroleum producing and refining, petrochemical and chemical manufacturing, bulk storage and transfer operations, other industries consuming or producing liquids and vapors.

Types of storage tanks

Storage Tanks classify as per their use, shape and Position.

  • Fixed-roof tanks
  • External floating roof tanks
  • Internal floating roof tanks
  • Domed external floating roof tanks
  • Horizontal tanks
  • Pressure tanks
  • Variable vapor space tanks
  • LNG (Liquefied Natural Gas) tank.

Our Sister concern M/S S.ENTERPRISES having expertise in Design and manufacturing Horizontal Tank, Pressure vessel and Vertical Tank in Non-Metallic MOC.

Horizontal Tank:

Horizontal tanks are constructed for both above-ground and underground service. Horizontal tanks are usually constructed of steel, steel with a fiberglass overlay, or fiberglass-reinforced polyester. Horizontal tanks are generally small storage tanks. Horizontal tanks are constructed such that the length of the tank is not greater than six times the diameter to ensure structural integrity. Horizontal tanks are usually equipped with pressure-vacuum vents, gauge hatches and sample wells, and manholes to provide accessibility to these tanks. In addition, underground tanks may be catholically protected to prevent corrosion of the tank shell. Cathodic protection is accomplished by placing sacrificial anodes in the tank that are connected to an impressed current system or by using galvanic anodes in the tank. However, internal cathodic protection is no longer widely used in the petroleum industry, due to corrosion inhibitors that are now found in most refined petroleum products.

Pressure Vessel

Engineering plastics have been used for pressure vessel applications for a long time. Significant advances in resin development are now creating still further opportunities. Plastics of increasing stiffness and toughness have been commercialized. New amorphous plastics, suitable for blow molding sizable parts, have also been developed, opening the way to one step manufacturing of these products. The above activity creates new opportunities for pressure vessels in engineering plastics.

Normally when we think of very hot or even boiling liquids and pressure vessels, we think of metallic containers. The use of plastics for these applications is not the first thing that comes to mind. However, plastic pressure vessels surround us and are so common we may not notice them. Some of them operate at elevated pressures and temperatures.
