Abstract
The utility model relates to a pitch-based adhesive pyrocondensation sleeve, and mainly deals with the problem existed in prior pyrocondensation art that a secondary bonding and sealing can not be formed, and comprises a polyethylene pyrocondensation body (1) and a pitch-based adhesive composite layer (2) which is arranged at the inner side of the pyrocondensation body and is compressed to match with the shape of the pyrocondensation body. The utility model has the advantages of good bonding performance and good sealing performance, the adhesive layer of the sleeve does not solidify and does not flow at any temperature.
Description
Technical field:
The utility model relates to a kind of thermal shrinkable sleeve, especially the asphalt base glue thermal shrinkable sleeve of finishing welding bead protection and antisepsis in the oilfield construction field.
Background technique:
In the oilfield construction field, when polyethylene, glass fibre reinforced plastics thermal insulation pipe shell and the steel pipe that has a polyethylene protective layer are carried out weld job, all be to adopt on polyethylene sheets, to smear thermosol usually, then this sheet material is placed the heating of welding bead repaired mouth place.Because thermosol trickles under condition of overhigh temperature through regular meeting; peel off and cause shell or protective layer because wriggling takes place for thermosol and polyethylene, glass fibre reinforced plastics shell thermal insulation pipe and be subjected to displacement; make it can't form the bonding and sealing of secondary, also just can't finish welding bead protection and antisepsis.
The model utility content:
Can trickling take place because temperature is too high and then cause forming deficiency bonding and sealing in order to overcome the material that plays bonding and seal action that exists in existing welding bead protection and the aseptic technic; the utility model provides a kind of asphalt base glue thermal shrinkable sleeve; this asphalt base glue thermal shrinkable sleeve has bonding good with sealing, the characteristics that its glue-line does not solidify under any temperature and do not trickle.
The technical solution of the utility model is: this kind asphalt base glue thermal shrinkable sleeve comprises polyethylene pyrocondensation body 1, in described pyrocondensation body inboard one asphalt base glue composite bed 2 is arranged, this composite bed and the pressing of described pyrocondensation body, and its shape and described thermal shrinkable sleeve shape match.
Described polyethylene pyrocondensation body 1 can be crosslinking with radiation tubular polyethylene sheet material.
Described polyethylene pyrocondensation body 1 also can be crosslinking with radiation sheet polyethylene sheets.
The utlity model has following beneficial effect: because the asphalt base glue composite bed in the such scheme has at high temperature the characteristic of not trickling, not solidifying under the low temperature; make that no matter polyethylene, glass fibre reinforced plastics protective tube shell and polyethylene protective layer with the thermal shrinkable sleeve asphalt base glue what kind of creeping deformation take place and produce displacement or can both remain bonding and seal action when peeling off because of mechanical deterioration produces, so have good sealing and cementability.
Description of drawings:
Accompanying drawing 1 is that to select polyethylene tubulose sheet material for use be the structure sectional view of pyrocondensation body material to the utility model;
1-polyethylene pyrocondensation body among the figure, 2-asphalt base glue composite bed.
Accompanying drawing 2 is that to select polyethylene sheet sheet material for use be the structure sectional view of pyrocondensation body material to the utility model;
1-polyethylene pyrocondensation body among the figure, 2-asphalt base glue composite bed.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in FIG., this kind asphalt base glue thermal shrinkable sleeve comprises polyethylene pyrocondensation body 1, in described pyrocondensation body inboard one asphalt base glue composite bed 2 is arranged, this composite bed and the pressing of described pyrocondensation body, and its shape and described thermal shrinkable sleeve shape match.
This polyethylene pyrocondensation body 1 can for crosslinking with radiation tubular polyethylene sheet material as shown in Figure 1; Also can be crosslinking with radiation sheet polyethylene sheets, as shown in Figure 2.Select for use which kind of material will decide according to on-site actual situations as the pyrocondensation body actually, usually tubulose pyrocondensation body is applicable to when soldered object is regular pipe or cylindrical body, and sheet pyrocondensation body then majority is applied to soldered object and exists when irregularly shaped.
When reality is used the tubulose thermal shrinkable sleeve, object after soldered is penetrated in the thermal shrinkable sleeve, this thermal shrinkable sleeve is placed the weld seam position, then thermal shrinkable sleeve is heated, asphalt base glue is bonded on the polyethylene and glass fibre reinforced plastics shell and polyethylene protective layer at welding bead two ends; To heat after the sheet material chucking then at actual when using the sheet thermal shrinkable sleeve, as to open the object of this sheet pyrocondensation body after soldered weld seam position.
Claims (3)
1, a kind of asphalt base glue thermal shrinkable sleeve comprises polyethylene pyrocondensation body (1), it is characterized in that: the inboard pressing of pyrocondensation body (1) has an asphalt base glue composite bed (2).
2, asphalt base glue thermal shrinkable sleeve according to claim 1 is characterized in that: described polyethylene pyrocondensation body (1) can be crosslinking with radiation tubular polyethylene sheet material.
3, asphalt base glue thermal shrinkable sleeve according to claim 1 is characterized in that: described polyethylene pyrocondensation body (1) can be crosslinking with radiation sheet polyethylene sheets.
