1、Scope and standard of products:
1.1 The R11、R112 design code in Horizontal oil tank can be applied to fuel oil tanks of industry oil depot and gas station;
1.2 Scope: The pressure is normal pressure; the temperature is -19℃~200℃; the medium is is fuel oil(diesel oil, gasoline and so on).
1.3 Steel Pressure Vessel GB 150-1998 and Steel Weld Normal Pressure Vessel JB/T 4735-1997

2、Main types of oil tanks
2.1 Please see the flow diagram about the oil supply system:
2.2 The ground horizontal oil tank and underground horizontal oil tank:the manufacture drawing, installation drawing and basic parameter chart for 5~100 M3 oil tank.
2.The operating well drawing of underground horizontal oil tank, the welding type drawing of joint pipe of oil tank, the inclined ladder drawing inner horizontal oil tank.
 
3、The determination of oil tanks:
　　The total volume will be decided by transportation ways and oil supply period and so on. The maximum consumption is no less than 20～30 days if is transported by train and vessel; The maximum consumption is no less than 5～10 days if is transported by car; The maximum consumption is no less than 20～30 days if is transported by pipe. The operation period of fuel oil equipment is from 12～16 per day in office building;  The operation period of fuel oil equipment is from 16～24 per day in high grade residence building and hotel.
 
4、Installation in the site:
4.1The thickness of cover soil on the top of underground oil tank is no less than 0.5m. The clean sand or fine soil can be used in around and the thickness is no less than 0.3m;
4.2The company will use the same ladders for the operation platform of oil tank. The underground operation well is designed for underground horizontal oil tank;
4.3The user should take some measures to fix and prevent floating for underground horizontal oil tank if the water level is too high.
4.4The oil tank can storage HFO and the the heater should be designed; the user should consider the bottom valve and joint in the material exit of underground oil tank.
4.5Take some measures for lightning protection, anti-static and firefighting. The inner anticorrosion should be decided by the medium and the outside anticorrosion should be decided by soil property.
4.6The height of vent pipe should be over 4m above ground. The nominal diameter of vent pipe should no less than 50mm and should be equipped flame arrester.
