Abstract
The utility model relates to a quick joint mold for a pipeline outer coating, and belongs to the technical field of corrosion prevention in oil/gas surface engineering. According to the quick joint mold for the pipeline outer coating, the upper end and the lower end of a mold body are connected to fixed joints; the two sides of the mold body are respectively connected to unfolding movable joints; the middle part of the mold body is connected to three injection molding ports. The quick joint mold has the advantages that injection molding fixed forming is carried out on single-component prepolymer materials, and can be widely applied to buried pipelines (asphalt, PE (Poly Ethylene), and the like) of major oil and gas field enterprises, so that the joint effect of the pipeline outer coating can be greatly promoted, metallic corrosion for a pipe body at the joint can be relatively effectively prevented, safe and stable operation for the whole pipeline is guaranteed, direct and indirect economic benefits and social benefits are higher, and the prospect is broad.
Description
Technical field
The utility model relates to a kind of pipeline external coating quick joint coating mould, belongs to oil gas ground engineering, aseptic technic field.
Background technique
Oil and gas pipeline generation explosion and leakage, will cause heavy economic losses and serious social influence.Pipeline is corroded and causes perforation or mechanical strength to decline being pipe safety to reduce causing one of major reason of explosion and leakage, and what buried steel pipe adopted is adds intensity level or spy to add intensity level anticorrosion, reaches 30～50 years projected life.If it is defective that joint coating on pipeline, benefit are hindered, within after pipeline is buried 3～5 years, just may cause leaking and explosion in these positions perforation, will have a strong impact on the working life of whole piece pipeline, even can cause whole piece pipeline abandonment.Find by data check and investigation widely, the achievement in research of carrying out early stage with regard to each large pipeline operation enterprise and related scientific research unit is seen, it has been generally acknowledged that and cause the reason that joint coating on pipeline lost efficacy mainly to concentrate on: the bonding failure of construction quality problem, hot melt adhesive, repaired mouth place epoxy primer this three aspects: that lost efficacy, along with scientific and technological development, also should deepen the research whether repaired mouth structure is suitable for, and consider the consistency problem of opening-supplementing material and pipeline external anti-corrosion layer.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of pipeline external coating quick joint coating mould.
A kind of pipeline external coating quick joint coating mould, upper end, the lower end of die ontology are connected and fixed joint; The both sides of die ontology connect respectively expansion active section, and the middle part of die ontology connects injection hole.
Injection hole has 3.
The utility model has the advantages that one pack system performed polymer material is carried out to the fixed-type processing of injection moulding, on the buried pipeline (pitch, PE etc.) of each major oil and gas field enterprise, can apply widely, riser tubing external coating repaired mouth effect greatly, can more efficiently avoid occurring the body metal erosion of repaired mouth place, ensure the safety and steady operation of whole piece pipeline, its direct indirect economic effect, social benefit are all higher, have a extensive future.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, does not form to improper restriction of the present utility model, wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
Obviously the many modifications and variations that, those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of pipeline external coating quick joint coating mould, the upper end of die ontology 1, lower end are connected and fixed joint 2; The both sides of die ontology 1 connect respectively launches active section 3, and the middle part of die ontology 1 connects injection hole 4.
Extending (500mmX3000mm band shape, thickness 3mm can freely be rolled into tubular), what can be suitable for is wider, applicable to multiple caliber and surface.Mould material therefor is stainless steel, duroplasts etc., spiral-lock is after pipe surface, fixed knot 2 is for being fixed on pipeline by mould, be convenient to carry out filling moulding and can spending coating trimming with repaired mouth place 45 and form tight structure of opening-supplementing material, after adding and closing after fastener, the interior pressure that can bear 1Mpa is at least air tight, thereby guarantees the material of the full question response of inner filling.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
Claims (2)
1. a pipeline external coating quick joint coating mould, is characterized in that the upper end of die ontology, lower end are connected and fixed joint; The both sides of die ontology connect respectively expansion active section, and the middle part of die ontology connects injection hole.
