Description
Technical field
The present invention relates to a kind of insulating joint field, be specifically related to a kind of band flexible glue layer with protective conduit function of surface
Insulating joint.
Background technology
On commercial plant, the corrosion hazards of pipeline is typically big, because at majority of case than the corrosion hazards in long distance pipeline
Under, pipeline can form corrosion cell with reinforced concrete foundation.Region can be utilized in different types of commercial plant region
Cathodic protection overcomes this corrosion hazards, and method therefor is similar to the method for local cathodic protection.Shielded region is not
Conditional, say, that between pipeline and that be connected and the pipeline of branch, there is no electric insulation.The locally mesh of cathodic protection
The battery current being not only external cathode structures to be compensated, and to make the abundant cathodic polarization of protected structures, from
And meet criteria for cathodic protection requirement.In the cathodic protection of local the change of pipe to soil potential only with near reference electrode relevant
System, and rare with distant place ground potential contact.When metal-electrolyte dissolution corrosion system is by cathodic polarization, current potential is negative to be moved, gold
Belonging to anodic oxidation reactions overpotential to reduce, response speed reduces, thus metal erosion speed reduces, referred to as cathodic protection effect.
The means of defence utilizing cathodic protection effect to alleviate metal equipment corrosion is called cathodic protection.It is passed through electricity by dispatch from foreign news agency road direction metal
Son, needed for depolarizing agent reduction reaction, so that burning reaction (betatopic reaction) is suppressed.Work as burning
When response speed is reduced to zero, only there is depolarizing agent cathode reaction in metal surface.
Insulating joint is for preventing couple corrosion in pipelined, and pipeline is carried out the critical elements needed for cathodic protection,
Being mainly used in gas transmission and distribution system and gas pressure regulating station, its effect is by each intersegmental, the gas pressure regulating station of gas transmission and distribution pipeline
And mutually insulated isolation, protects it from electrochemical corrosion, increases the service life between transmission & distribution pipeline.
But existing welding type connect insulating joint, the most uneven the most unsightly, used
Cheng Zhong, owing to rough surface causes pipe surface damage of material, is unfavorable for anti-corrosion insulation protection, causes high degree
On waste, be unfavorable for environmental protection.
Summary of the invention
The technical problem to be solved is the internal rough surface of insulating joint, it is therefore intended that provide one
There is the band flexible glue layer insulating joint of protective conduit function of surface, the problem solving the internal rough surface of insulating joint.
The present invention is achieved through the following technical solutions:
A kind of band flexible glue layer insulating joint with protective conduit function of surface, two sleeve pipes and a sleeve, it is characterised in that:
