Description
Technical field
The present invention relates to oil gas field corrosion and protection technical field, more particularly to a kind of replaceable sacrificial anode and replacing side
Method.
Background technology
Crude setting tank is the most basic crude Treatment in gathering station, storehouse, sewage treatment facility.Due to containing in tank bottoms water
The precipitate of crude oil, salt（Such as magnesium chloride, sodium chloride and calcium chloride）And sulfate reducting bacteria etc., so as to result in settling tank
The top tank structure of interior and connate water contact corrodes.Cathode protection technology can be very good to suppress to corrode, and most common method is
Sacrificial anode is installed additional in reservoir walls, so as to reach effective protection crude setting tank, extends the mesh of crude setting tank time between overhauls(TBO)
's.
After sacrificial anode runs out of, need to be changed.But as common anode is that ferrum foot is welded in top tank structure directly,
During replacing, it is necessary first to cut ferrum foot using oxygen-acetylene burner, new sacrificial anode is welded on top tank structure again then.But
There is problems with actual production process：
When the 1st, carrying out ferrum foot cutting operation, the high temperature of oxygen-acetylene burner can cause heat affected area in weld, to tank skin
Damage is produced, increases corrosion, safety hidden danger；
2nd, when new sacrificial anode is changed, also need to carry out cathodic Protection Design, layout again is carried out to anode；
3rd, get angry region as crude setting tank belongs to one-level, cutting and weld job be required to handle get angry formality can
Operation.Formality of getting angry is loaded down with trivial details, not only consumes substantial amounts of manpower and materials, can also cause high potential safety hazard.
