Process piping fixed station should adopt seamless. Buried pipe connections are to be welded. When there is severe corrosive effect on steel soil area buried pipeline, the choice of oil, soil corrosion resistance, static conductive composite pipe. In addition to these caveats, gas pipeline will also be required in the design of what?
1, Automatic Fuel Nozzle should adopt self-styled Automatic Nozzle, flow rate should not exceed 60L / min
2, when the tanker unloading unloading hose communicating, communicating oil and gas recovery hose, antistatic oil resistant hose should be used. Interconnecting hoses should not be less than the nominal diameter of 50 mm.
3, process piping at service stations should be laid underground, and can not pass through the station house and other built structures. When the oil pipeline and the trench, trenches and drains intersect, it should take appropriate measures to prevent leakage.
4, communicating with the tank inlet pipe, snorkel horizontal pipe, and oil and gas recovery tube should slope tank, its slope should be less than 2 ‰.
5, the oil pipeline system design pressure of not less than 0. 6MPa.
6, corrosion design process piping buried outside surface should be consistent with existing national standards "steel pipeline and storage tank corrosion control engineering design specification" of the relevant provisions of SY 0007, and should be used to strengthen the level of not less than the corrosion protection layer insulation.
