A storage tank is a container, usually for holding liquids, sometimes for compressed gasses (gas tank). The term can be used for reservoirs (artificial lakes and ponds), and for manufactured containers. Storage tanks operate under no (or very little) pressure, distinguishing them from pressure vessels. Storage tanks are often cylindrical in shape, perpendicular to the ground with flat bottoms and a fixed or floating roof.

Storage tanks are available in many shapes: vertical and horizontal cylindrical; open and closed top; flat bottom, cone bottom, slope bottom and dish bottom. Large tanks tend to be vertical cylindrical, or to have rounded corners transition from vertical side wall to bottom profile, to easier withstand hydraulic hydrostatically induced pressure of the contained liquid. Most container tanks for handling liquids during transportation are designed to handle varying degrees of pressure.

We design and manufacture Storage Tanks for different Applications. We design Floating Roof tanks, Dome Roof tanks, Cone roof tanks, Double wall (Cryogenic) Tanks etc as per National and International codes such as API 650, API 620, and Indian Standard.

We design and manufacture as per Australian Standard AS 1692 for Storage Tank to be installed in Australian Territories.

Depending on the desired design conditions, these tanks are equipped with a conical roof or a domed roof, with or without anchors and stiffening rings, such as wind girders or top corner rings. These tanks are provided with a spiral staircase, a cage ladder or a stairway.

Roof Types

  • Conical/ Domed / Removable roof
  • Double bottom / Cone up/down
  • Top corner ring/ Wind girders
  • Umbrella
  • Open Top
  • Knuckle
  • Flat


Drinking Water Tanks

We design tanks suitable for the storage of Drinking water. We also provide internal lining as per requirement ideal for drinking water which does not allow any build-up of slime, algae, or any growth of organic matter or suspended particles, calcination etc. The drinking Water tanks can be in the form of a Ground Storage Reservoir (GSR) or Elevated Storage Reservoir (ESR).

Milk Storage Tanks

The Milk Storage Tank offered by us is a high-capacity tank widely used for storing milk. We use the highest grade material for manufacturing Milk Storage Tank. These Milk Storage Tanks can store raw milk as well as processed milk for a long time.

These Horizontal Milk Storage Tanks are made out of high-quality raw materials with the help of high-tech machines and by applying advanced methods under the stringent supervision of our team of professionals.

Raw Water Tanks

Raw water is the water found in the environment that has not been treated and does not have any of its minerals, ions, particles, bacteria, or parasites removed. Raw water includes rainwater, groundwater, water from infiltration wells, and water from bodies like lakes and rivers.

Raw water is generally unsafe for human consumption due to the presence of contaminants. A major health problem in some developing countries is the use of raw water for drinking and cooking.

These Tanks have found extensive applications for storage of Raw and Treated water for various industrial applications, from water for the process to boiler feed water. The capability of large-scale storage with clusters of tanks enables customers to have Millions of litres of Water storage. Infinity liner is suitable to handle high TDS raw water whether taken from underground source or directly from river etc. Raw Water & Treated Water storage using Kingspan Rhino Tanks find applications in the Power, Steel, Mining, Sugar Industries and Textile etc. Food-processing and Beverage Industries require very high quantities of Water for their process and cleaning application.

Edible Oil Tanks

We design Tanks with liner for the storage of edible oils. Some of the oils which can be stored in our tank are – Refined oil, Sunflower oil, Fish oil storage, Mustard oil etc.

Our Tanks are adaptable and can be made suitable to store oils like coconut, palm oil etc which tend to coagulate in winters. We can provide a special top-mounted mechanism through which steam or hot water can be passed and resultant lateral heat can liquefy the oil without damaging the liner or the tank.

Other Applications:

  • Pharmaceutical storage tank
  • Bulk storage vessels (stainless steel / mild steel)
  • Cellar tanks
  • Brew houses
  • Food and beverages Industry
  • Coatings Industry
  • Agricultural Industry
  • Rubber Industry
