Steel Diesel Tanks FAQs

  • What are steel bunded fuel tanks?

    A steel bunded fuel tank is a steel vessel for storing and/or dispensing fuels that features both an inner tank and outer tank. The inner tank stores the fuel, while the outer tank is a failsafe to capture fuel in the event of leakage or spillage from the inner tank.

    By employing this ‘tank within a tank’ approach, a steel bunded fuel tank helps to minimise environmental damage in the event of spillage and helps to provide an extra layer of security against would-be thieves and drill-siphoning. As a result of this ingenuity, bunded fuel tanks are the only legally suitable options for fuel storage in UK-based industrial and commercial situations and are also attractive for domestic use.

    RPM’s range of steel bunded fuel tanks and bunded fuel stations come in capacities of up to 10,000 liters, and features extras including lockable security cabinets, integral diesel pumps, and more. A steel bunded fuel station from RPM is your one-stop solution for safely storing and dispensing large quantities of diesel with total peace of mind.

  • What is a steel bunded fuel tank used for?

    RPM’s range of steel bunded fuel tanks is ideal for use across a wide range of applications. If you need to store or dispense quantities of diesel fuel up to 10,000 litres in a commercial, industrial, agricultural setting, or on a construction site, we have the solution you seek.

    Our steel diesel tanks feature robust, all-steel construction, ensuring reliability and long life of service under all circumstances. Thanks to this quality workmanship, and the fact that these tanks are bunded as standard, you can enjoy peace of mind knowing that your steel diesel fuel tank fully satisfies the latest requirements from the EA, OFTEC, and additionally PPG02.

  • How much does a steel bunded fuel station cost?

    The range of steel bunded fuel stations on offer from RPM Fuels and Tanks cater to a range of price points. Our lowest capacity station starts at £1,335.00 + VAT, and the highest capacity tank starts at £4,750.00 + VAT. The inclusion of optional extra components will alter the price.

    There are many variables that impact how much a steel bunded fuel station should cost. The thickness of the steel used, the capacity of the tank, included extras such as battery-operated pumps, nozzles, hose, lockable security cabinets etc are all variables to consider. Whatever your requirements, RPM has the robust diesel fuel storage solution you seek.

  • What does OFTEC stand for?

    OFTEC stands for the Oil Firing Technical Association. A steel diesel fuel tank that is said to be OFTEC certified means that the design meets the strict safety and environmental criteria set by the OFTEC. These vary according to what capacity the fuel tank is manufactured to.

    One key part of OFTEC certification involves the size of the tank’s bund. To be OFTEC certified, a fuel tank with a capacity that is greater than 200 litres must be bunded, with the outer bund being capable of containing 110% of the tank’s storage capacity. Another key factor that decides whether a fuel tank can be OFTEC certified is whether the tank includes a gauge.

    It is highly recommended that your steel diesel fuel tank requirements are discussed with an OFTEC registered technician. They will be able to recommend definitively what material and size of tank you will need based on your situation, requirements, and environment. An OFTEC registered technician will also be able to make recommendations about tank location, base support, and inspections.

  • What is the difference between red and white diesel?

    White diesel is the ultra-low sulphur diesel typically used for road-going vehicles. White diesel also contains a higher concentration of cetane than red diesel. Red diesel is used for certain types of machinery, tractors, and combine harvesters, with a red dye added to differentiate it visually from white diesel.

    Red diesel (also known in other countries as gas oil) was traditionally used for domestic heating, though its use has since been replaced with Kerosene (also known as heating oil). Its use is typically commercial, and should not be put into a piece of machinery, plant, or vehicle unless the manufacturer recommends it.

  • How far should a steel diesel tank be from a building?

    At RPM Fuels and Tanks, we like to adhere to the industry standards and models of safety. Steel diesel tanks should be situated at least 2 metres away from any boundaries or buildings, and at least 6 metres away if the steel diesel tank fuel capacity is over 3,500 litres.

    This is the standard most professional oil-related sectors should obey when dealing with non-domestic tanks. Choosing a low-risk location (i.e. a place with limited water) is vital in not only keeping the environment safe but also keeping yourself safe from any freak catastrophes.

    If ever you feel unsure about the state or rules regarding steel diesel tank recommended regulations, don’t hesitate to get in touch with our team of venerable professionals. With their expertise, our team can guide you through any situation that arises.

  • How do you clean a steel diesel tank?

    If your steel tank is dirty or greasy to the point of preventing optimum operations, it’s time clean it. Cleaning your steel diesel tank is a way to ensure the longevity of your storage, and an excellent chance to look-over your tank. Let’s explore how you might clean one.

    Step-by-step you should first empty the steel tank completely then remove the fuel pump, insert a hose into the fuel tank and begin pouring a stream of clean, hot water. Whilst the water is filling, spray a mild detergent or degreaser into the tank. If opening allows, use a brush to loosen debris from the sides of the tank.

    Remember that you can always consult a member of our team by getting in contact, and one of our venerable fuel tank experts will get in touch with you and analyse what your tank specifically may need in terms of cleaning and give you specialised advice.

    AT RPM Fuels and Tanks we recommend that clients check their steel diesel tanks annually when the OFTEC certified heating engineer calls to service the boiler. We also recommend that clients inspect their tank once a week for any early signs of problems such as corrosion to the tank’s walls or sudden dips in oil levels. Tanks are required to have an oil tank contents gauge to help prevent spillage and overflowing.

    You will want to extend your steel diesel tanks lifespan as much as possible, but you may find that, after several years of build-up, you may have to consider replacing your steel diesel tank. If such a situation occurs, don’t hesitate to browse our site for a suitable replacement.

  • How do you repair a steel tank?

    Despite their high durability, we have to accept that there can be occasions when steel tanks are damaged and in need of repair. We would firstly recommend that you siphon your tank of any remaining fuel to prevent sticking. There are several different ways to repair your damaged fuel tank.

    Qualified technicians tend to use a verified and reputable repair kit or opt to weld. It is also a good idea to ensure that your tank is empty and clean before making any repairs, and also to make sure you know where your tank’s shut off and isolation valves are.

    If you find yourself lost at any point, don’t hesitate to get in touch with our team of apt professionals at RPM Fuels and Tanks. Any one of our venerable professionals has years of experience in the fuelling sector and can walk you through the ideal method of repair for your specific steel diesel tank. They can also give you a list of tell-tale signs that your steel diesel is damaged beyond repair and requires replacement.
