Rules governing the oil and gas pipeline industry call for at least 2.5 feet of “cover” over the typical oil or gas pipeline.
Buried Oil Supply Pipes
Recommended installation is as follows: A trench should be excavated to a depth of 450mm; 40mm of compacted sand is laid on the bottom of the trench; the oil pipe positioned, and a further 40mm of compacted sand is laid above the pipe; Builder's grade polyethylene is laid above the sand; and.
Plastic pipework is allowed to be used on oil boilers, provided there is at least 1000mm copper pipe connection to the boiler before any plastic. Plastic pipework may also be used on under floor heating systems in conjunction with a blending valve.
UPVC coated copper pipe is recommended for oil supply lines between the tank and the boiler (or similar appliance).
10mm Copper Pipe Per Metre
10mm copper pipe / microbore tube. 10 mm outside diameter, 0.7mm wall thickness, 8.6mm nominal inside diameter.
760mm away from a non-fire rated boundary, such as a wooden boundary fence.
As long as the Water pipe, Gas pipe or Oil pipe, coming into your property are metallic, Main Bonding is compulsory in all circumstances even when the rest of the pipes in your house are plastic.
Tubing comes in many different diameters and wall thicknesses. But the most commonly used tubing items are 2 3/8”, 2 7/8” and 3 ½”.
It's important to keep vent outlets clear to allow a free passage of air in and out of the tank.
PVC is resistant to many alcohols, fats, oils and aromatic free petrol. It is also resistant to most common corroding agents including inorganic acids, alkalis and salts.
If you look in your basement, you will see a line running from your oil tank to your boiler or furnace. This line carries the oil from one to the other and may be buried beneath concrete basement floors or run overhead.
Oil supply lines are normally run in plastic coated annealed copper and some approved types of plastic pipe. Soft soldered fittings cannot be used, nor can galvanised fittings as they can cause electrolytic corrosions of dissimilar metals.
If the oil level is a little above the full mark, that shouldn't cause problems. If it's overfilled by half a quart or more, or foam shows on the dipstick, the best fix is to have the oil drained and refilled to the proper level.
Your furnace or boiler will most likely stop running if you let the oil level get down to about four inches, or about 32 gallons. It's also important to note that if you have an older tank, there is a good chance that impurities or sediment have settled in the bottom.
To comply with the Regulations on Oil Storage you must ensure all pipework, above and below ground, is correctly positioned and properly maintained. There is a particular risk of oil leaks from poorly fitted pipes. Ideally, pipes should be above ground.
According to 'The Department of the Environment', they recommend that pipes should be buried at least 600mm (two feet) underground. At this depth, the soil acts as a natural insulator and prevents them freezing.
There are essentially three major types of pipelines along the petroleum transportation route: gathering systems, crude oil pipeline systems, and refined products pipeline systems.
Rocks in and around certain oil- and gas-bearing formations may contain natural radioactivity. Drilling through these rocks or bringing them to the surface can generate waste materials that contain radioactivity.
if the reading is not <0.05 then you need to determine whether it is extarneous or not, you can test this by applying a 500v dc IR test between the MET and the suspected part, basically if the reading is <22,000 ohms then it is extraneous if it is >22,000 ohms then it is considered isolated and need not be bonded.
Oil pipelines are made from steel or plastic tubes which are usually buried. The oil is moved through the pipelines by pump stations along the pipeline. Natural gas (and similar gaseous fuels) are pressurized into liquids known as Natural Gas Liquids (NGLs). Natural gas pipelines are constructed of carbon steel.
Bonding is essential for your gas and water installation pipes that connect your home with the Earth Terminal in or adjacent to your consumer unit. Without bonding, the risk of faulty pipework becoming live increases - this is a serious health and safety hazard you don't want to ignore.
Your tank needs to be a specific distance away from non-fire rated parts of your property; for example, 1.8m away from eaves, sheds and gazebos and 760mm away from boundary fencing. You should not place a bunded oil tank within 1.8m of the doors, windows or any other construction openings.
An oil tank has to be a minimum of 1.8 metres away from any part of a building or construction that isn't fire resistant, such as doors, windows, eves and cladding.
Oil Tank Building Regulations
It's no higher than 3m. Its total height is no more than 2.5m if it's within 2m of a boundary. Additions or other buildings only cover half or less of the area surrounding the original house.
