Abstract
The utility model relates to metering station cathodic protection for the corrosion prevention of a crude oil transportation metal pipeline in oil exploitation field. Copper cable lugs are welded on crude oil transportation pipes at pipeline nodes of an oil extraction metering station. An insulating box is arranged outside the cable lug. One end of a lead wire is connected with the copper cable lug through a copper bolt and the other end of the lead wire is welded with a female connecting plug which is connected with a male connecting plug. The other end of the male connecting plug is connected with a wire post of a sacrificial anode block. An insulating sleeve is arranged outside the connection of the female connecting plug and the male connecting plug, therefore the sacrificial anode block is convenient to replace when being used up and the corrosion prevention aim of the crude oil transportation metal pipeline of the oil extraction metering station is achieved.
Description
Affiliated field:
The galvanic protection of the utility model test satellite location is a kind of outer output oil metal pipe line corrosion-resisting device that is used on each pipeline node of oil production oil recovery test satellite location, reaches the outer etch-proof purpose of output oil metal pipe line of oil recovery test satellite location.
Background technology:
At present; known test satellite location galvanic protection generally all is used in the protection against corrosion of buried metal pipe; there is potentiostatic method also to bury the ground sacrificial protection; but burying underground of sacrificial anode all is disposable non-exchange; being connected between metal pipe line and the sacrificial anode is all dead with the welding process weldering, and such structure method of attachment all exists if non-exchange needs are newly buried underground when the sacrificial anode piece uses up, and quantities is big; difficulty of construction is also big, and the high defective of construction cost.
Summary of the invention:
The utility model designs at the deficiency of above-mentioned existence, and its objective is provides the galvanic protection of a kind of oil recovery test satellite location, reach convenient when the domestic animal anode block uses up, change convenient, the purpose that need not construct again, save cost.
The utility model is achieved like this: it is to be welded with copper line nose on the outer output oil metal tube on each pipeline node of oil recovery test satellite location, in its outside insulation booth is installed, with brass bolt lead one end is connected with copper line nose, the other end is welded with the female plug joint and is connected with it with the male plug joint, the other end of male plug joint is connected with the wire column of sacrificial anode piece, is with insulation covering at the female plug joint with the outside that the male plug joint is connected.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described further, Fig. 1 is a structure diagram of the present utility model.
Among Fig. 11, metal tube; 2, copper line nose; 3, insulation booth; 4, brass bolt; 5, lead; 6, female terminal stud; 7, public access terminal; 8, sacrificial anode piece; 9, wire column; 10, insulation covering
Embodiment:
The utility model is achieved like this: it is to be welded with copper line nose (2) on the outer output oil metal tube (1) on each pipeline node of oil recovery test satellite location, insulation booth (3) is installed in its outside, with brass bolt (4) lead (5) one ends are connected with copper line nose (2), the other end is welded with female plug joint (6) and is connected with it with male plug joint (7), the other end of male plug joint (7) is connected with the wire column (9) of sacrificial anode piece (8), and the outside that is connected with male plug joint (7) at female plug joint (6) is with insulation covering (10).
Since adopted such scheme just can realize convenient when the domestic animal anode block uses up, the replacing conveniently, the purpose that need not construct again, save cost, simple in structure.
