Description
Technical field
This utility model is related to a kind of insulating joint field and in particular to a kind of insulation being applied to long oil and gas pipeline connects
Head.
Background technology
On commercial plant, the corrosion hazards of pipeline are typically big than the corrosion hazards in long distance pipeline, because in most of feelings
Under condition, pipeline can form corrosion cell with reinforced concrete foundation.Area can be utilized in different types of commercial plant region
Overcoming this corrosion hazards, method therefor is similar to the method for local cathodic protection for domain cathodic protection.Shielded region is
Do not have conditional that is to say, that pipeline is not electrically insulated and the pipeline of branch between with being connected.Local cathodic protection
Purpose is not only the battery current that will compensate external cathode structures, and will make the abundant cathodic polarization of protected structures,
Thus meet criteria for cathodic protection requiring.In the cathodic protection of local the change of pipe to soil potential only near reference electrode relevant
System, and rare with distant place ground potential contact.When metal-electrolyte dissolution corrosion system is subject to cathodic polarization, current potential is born and is moved, gold
Belong to anodic oxidation reactionses overpotential to reduce, response speed reduces, thus metal erosion speed reduces, referred to as cathodic protection effect.
It is called cathodic protection using the means of defence that cathodic protection effect mitigates metal equipment corrosion.Electricity is passed through by dispatch from foreign news agency road direction metal
Son, for needed for depolarizing agent reduction reaction, so that metal oxidation reaction (betatopic reaction) is suppressed.When metal oxidation
When response speed is reduced to zero, only there is depolarizing agent cathode reaction in metal surface.
Insulating joint is to be to prevent couple corrosion in pipelined, carries out the critical elements needed for cathodic protection to pipeline,
It is mainly used in gas transmission and distribution system and gas pressure regulating station, its effect is by each intersegmental, gas pressure regulating station of gas transmission and distribution pipeline
Mutually insulated isolation, protects it from electrochemical corrosion, increases the service life and between transmission ＆ distribution pipeline.
But the insulating joint that existing welding type connects, generally in shape uneven very unsightly, using
Cheng Zhong, because rough surface leads to pipe surface damage of material, is unfavorable for anti-corrosion insulation protection, causes high degree
On waste, be unfavorable for environmental protection.
