Abstract
The utility model relates to an anode pipe patching device and the purpose is to solve the problems of the background technology. The utility model is characterized in that: an alloy tubular anode body (5) is fixed in two pipes (1) by a locating ring (3). The anode pipe patching device is characterized by easy operation, convenient construction, good quality, large anti-corrosive area and low construction cost.
Description
Technical field:
The utility model relates to used interior anticorrosion of oilfield surface engineering pipeline, especially pipeline inner anode repaired mouth device.
Background technique:
In oilfield surface engineering pipeline construction process, in order to guarantee the quality of pipeline, prevent the pipe welding port internal corrosion, need make internal joint patch to the steel pipe weld bond.And at present used internal joint patch device is little owing to reasons in structure exists the anti-corrosion protection regional extent, the problem of complicated operation, constructional difficulties, and also quality is difficult for guaranteeing that the construction cost height is difficult for applying.
The model utility content:
In order to solve the problem in the background technique, the utility model provides a kind of pipeline inner anode repaired mouth device, and this pipeline inner anode repaired mouth utensil has simple to operate, easy construction, and quality is good, and the anti-corrosion protection regional extent is big, the characteristics that construction cost is low.
The technical solution of the utility model is: this pipeline inner anode repaired mouth device comprises pipe, comprises pipe, is fixed with alloy material sheath body by positioning ring in two pipes.
In the such scheme two pipe corresponding joints is built-in with cover in the Corrosion Resisting Steel, be filled with seal ring in the outer ring groove of cover two ends in the Corrosion Resisting Steel, the cover two ends are connected with alloy material sheath body in the Corrosion Resisting Steel, and the cover outer fixing has the positioning ring that is clamped between two pipe ends in the Corrosion Resisting Steel; Be filled with sealer between cover and two pipe ring chambeies in the Corrosion Resisting Steel; Cover also can be connected with alloy material sheath body by an end in the Corrosion Resisting Steel.
The utlity model has following beneficial effect: this pipeline inner anode repaired mouth device is owing to take such scheme, because of the seal ring outside the cover two ends in cover and the Corrosion Resisting Steel in the employing Corrosion Resisting Steel, to sealing in the pipe weld bond place, medium can not be entered, thereby effectively prevent to manage the corrosion at interior weld bond place, prolonged the working life of pipe.Simultaneously because of overlapping two ends in the Corrosion Resisting Steel by welding, the alloy material sheath body of riveting or be threaded; MEDIA FLOW is through herein the time; realize anode loss protection in the pipe; reduced pipeline coating breakage spot corrosion rate; further improved the antiseptic property in the pipeline; increased the anti-corrosion protection regional extent, can be to carrying out anti-corrosion protection in the whole piece pipeline.This pipeline inner anode repaired mouth utensil has simple to operate, easy construction thus, and quality is good, increases the anti-corrosion protection regional extent, the characteristics that construction cost is low.
Description of drawings:
Accompanying drawing 1 is the utility model plan view figure.
1-pipe among the figure, cover in the 2-Corrosion Resisting Steel, 3-positioning ring, 4-seal ring, 5-alloy material sheath body.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this pipeline inner anode repaired mouth device comprises pipe 1, two pipes, 1 corresponding joints is built-in with cover 2 in the Corrosion Resisting Steel, be filled with seal ring 4 in the cover 2 two ends outer ring grooves in the Corrosion Resisting Steel or in Corrosion Resisting Steel, overlap filling with sealant between 2 and two pipes, 1 ring cavity, cover 2 both ends or one end are connected with alloy material sheath body 5 in the Corrosion Resisting Steel, and cover 2 outer fixing have the positioning ring 3 that is clamped between two pipes, 1 termination in the Corrosion Resisting Steel.
During actual the use, at first seal ring 4 is enclosed within respectively in the groove that overlaps 2 two ends in the Corrosion Resisting Steel or in Corrosion Resisting Steel and smears sealer outside the cover 2, by welding, riveted joint or screw thread link alloy material sheath body 5 is connected to then and overlaps both ends or one end in the Corrosion Resisting Steel, again cover 2 in the Corrosion Resisting Steel is inserted respectively in two pipes 1, two pipes, 1 termination is clamped the positioning ring 3 of cover 2 outer fixing in the Corrosion Resisting Steel, by positioning ring 3 welding location with realize being electrically connected of pipeline and repaired mouth anode, manage 1 by welding with two at last and couple together.Pipeline is gone into operation after the operation, because of seal ring 4 or sealer by cover 2 and two ends in the Corrosion Resisting Steel, in two pipes, 1 weld bond, located to form the annular space of a sealing, the medium of stream can not enter in the pipe 1, thereby two pipes have been played antisepsis in the 1 weld bond place, effectively prolonged and managed working life of 1.Simultaneously because of overlapping 2 two ends in the Corrosion Resisting Steel by welding, the alloy material sheath body 5 of riveting or be threaded; MEDIA FLOW is through herein the time; according to electrochemical principle; realize anode loss protection in the pipe; reduced pipeline coating breakage spot corrosion rate; further improve the antiseptic property in the pipeline, increased the anti-corrosion protection regional extent, can be to carrying out anti-corrosion protection in the whole piece pipeline.This pipeline inner anode repaired mouth utensil has that the anti-corrosion protection regional extent is big, simple to operate, easy construction thus, and quality is good, the characteristics that construction cost is low.
