We manufacture a range of above or below ground, single or double skinned, integral or externally bunded tanks in a range of stainless or carbon steels.
We manufacture a wide range of horizontal tanks in carbon and stainless steel. You can choose from underground tanks, manufactured in accordance with BS.EN.12285-1:2018, or above ground tanks manufactured in accordance to BS.EN.14015:2004 and BS.799 part 5:2010. Due to the bespoke nature of many of our tanks, there are occasions when we use elements of these codes and ‘good engineering practice’ to meet the customers need.
Underground tanks benefit from being double-skinned, essentially a tank within a tank. They can also be configured to have more than one compartment allowing different liquids to be stored in one tank. These tanks do not incorporate a bund like many above-ground tanks but do incorporate continuous leak detection via a pressure monitoring system. To ensure the integrity of both the inner and outer tank a small pressure is applied to the space between the two tanks, this is known as the interstitial space. This pressure is constantly monitored and in the event of either skin being compromised air will either bubble into the fuel or leak to ground and an alarm is triggered, this is known as Class 1 leak detection. This alarm system can easily be incorporated into a bigger facilities management system.
Above-ground tanks are manufactured to meet the exact requirements of each site, allowing flexibility in the diameter and length of the tank to meet the volume required. We manufacture single skin tanks up a diameter of 4.4m and a capacity of 250,000 litres, larger capacities can be produced but owing to the difficulties in transporting large capacity tanks these are normally made in two halves which are then bolted together on-site. These tanks sit on cradles specifically designed to meet the requirements of the tank and the site.
Integrally bunded tanks offer a neat alternative to traditional open bunds avoiding the inevitable collection of water and rubbish and fully meeting the requirement of the Oil Storage Regulations. This design is similar to underground tanks in that the design is a tank within a tank, however, this design allows for any liquid that escapes from the inner tank to be captured and contained within the outer tank. The outer tank will normally have a capacity greater than 110% of the inner tank volume.
The advantages of horizontal cylindrical tanks offer are:
