Abstract
The utility model discloses an insulating tube connection structure, including the insulating tube, the insulating tube comprises steel pipe (3), heat preservation (2) and protective layer (1), and steel pipe (3) welding of two insulating tubes is in the same place, and outside suit electrocast sleeve (4) are seted up on electrocast sleeve (4) porose (5). The utility model discloses an electrocast sleeve replaces pyrocondensation area end -blocking, and the construction is simple swift to set up on electrocast sleeve porose, the inside fill insulant material of clearing hole. Adopting this connection structure, can improving the connection efficiency of insulating tube, the roughness also can be guaranteed.
Description
Technical field
This utility model relates to the attachment structure of a kind of insulating tube.
Background technology
Current insulating tube, when docking, is first stripped out the steel pipe of joint, by steel-pipe welding together, then is coated with heat-insulation layer on steel pipe, finally encapsulates with pyrocondensation belt. This method processes comparatively laborious, and the flatness of junction is bad guarantee also.
Summary of the invention
The technical problems to be solved in the utility model is: the problems referred to above that current insulating tube structure in succession exists, it is provided that a kind of new attachment structure.
The technical solution of the utility model is:
A kind of insulating tube attachment structure, including insulating tube, insulating tube is made up of steel pipe, heat-insulation layer and protective layer, and together, outside is set with electric melting sleeve to the steel-pipe welding of two insulating tubes, electric melting sleeve is offered porose.
Insulation material it is filled with between electric melting sleeve and steel pipe.
The beneficial effects of the utility model:
Electric melting sleeve is adopted to replace pyrocondensation belt end-blocking, simple and fast of constructing, and offer porose on electric melting sleeve, insulation material is inwardly filled by hole. Adopt this attachment structure, it is possible to improve insulating tube joint efficiency, flatness it is also ensured that.
Accompanying drawing illustrates:
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Such as figure, insulating tube is made up of steel pipe 3, heat-insulation layer 2 and protective layer 1, and heat-insulation layer 2 is RPUF, and protective layer 1 is managed for high density polyethylene (HDPE) PE. First steel pipe 3 is stripped out during docking, put electric melting sleeve 4 and shift to side, two steel-pipe weldings together, then electric melting sleeve 4 is moved to joint, energising electric melting sleeve 4, complete welding, in electric melting sleeve 4, spray into hard polyurethane foams finally by the hole 5 on electric melting sleeve 4, complete encapsulation.
Claims (2)
1. an insulating tube attachment structure; including insulating tube, insulating tube is made up of steel pipe (3), heat-insulation layer (2) and protective layer (1), it is characterised in that: the steel pipe (3) of two insulating tubes welds together; outside suit electric melting sleeve (4), electric melting sleeve (4) is offered porose (5).
2. insulating tube attachment structure according to claim 1, it is characterised in that: it is filled with insulation material (6) between electric melting sleeve (4) and steel pipe (3).
