Abstract

The utility model discloses a pipe with the ends provided with bushings. The pipe comprises a pipe body (1), and the anti-corrosion metal bushings (2) embedded into the pipe are arranged at the pipe ends of the pipe body (1). Due to the structure, an inner layer plastic cement hose of the steel plastic composite pipe is prevented from falling off and being damaged. Flanges (201) protruding out of the pipe ends of the pipe body (1) are arranged at the outer ends of the anti-corrosion metal bushings (2). The positions between the flanges (201) and the end faces of the pipe body (1) are coated with liquid epoxy resin serving as adhesive, therefore, the situation that conveying mediums in the pipe permeate into the positions between the steel pipe and the plastic cement hose and consequently the steel pipe is corroded is completely eradicated, meanwhile, separating and falling off of the plastic cement hose are prevented, and the service life of a pipeline system is prolonged.

Description

A kind of termination is with the tubing of lining
[technical field]
The utility model relates to a kind of tubing, more specifically says the tubing of a kind of termination with lining.
[background technique]
Along with improving constantly of social life level, people are also more and more higher to the concern of healthy and environmental protection.In order to reduce the secondary pollution of drinking water quality, the feedwater piping in many cities and towns extensively adopts steel-plastic composite pipe.But also can there be some drawbacks in steel-plastic composite pipe in practical engineering application, for example, owing to managing interior medium washing away, corroding the end face of steel-plastic composite tube connection part for a long time, the pipe end plastic pipe can separate, come off with cover steel pipe thereon, even can the blocking pipe system when serious, cause pipeline normally not move.
[summary of the invention]
The utility model purpose is to have overcome the deficiencies in the prior art, provides a kind of simple and practical, avoid pipe end place steel pipe to separate, come off with plastic pipe and termination that the defect such as plastic pipe breakage produces with the tubing of lining.
The utility model is achieved through the following technical solutions:
A kind of termination, with the tubing of lining, comprises body, it is characterized in that: be provided with at described body pipe end edge the anti-rust metal lining embedded in pipe, described anti-rust metal lining outer end is provided with evagination in the flange of described body pipe end.
Termination as above, with the tubing of lining, is characterized in that: described body comprises steel pipe, is arranged with plastic pipe in steel pipe, between described plastic pipe and described steel pipe by the hot melt adhesive adhesion.
Termination as above, with the tubing of lining, is characterized in that: described plastic pipe is that PE or PE-RT make.
Termination as above, with the tubing of lining, is characterized in that: on the surface of contact of described flange and described body, be coated with tackiness agent.
Termination as above, with the tubing of lining, is characterized in that: described tackiness agent is liquid epoxies.
Termination as above, with the tubing of lining, is characterized in that: described anti-rust metal lining is the stainless steel lining.
Termination as above, with the tubing of lining, is characterized in that: described anti-rust metal lining is copper sheathing.
Termination as above, with the tubing of lining, is characterized in that: described anti-rust metal lining wall thickness is 0.4 to 1.0mm.
Termination as above, with the tubing of lining, is characterized in that: described tube wall has groove near pipe end place's roll extrusion.
Compared with prior art, the utility model has the following advantages:
1. in body, edge is established the anti-rust metal lining, has prevented conventional steel plastic composite separating near pipe end place plastic pipe layer and cover steel pipe thereon.
2. the flange on the anti-rust metal lining is affixed on the body end face, has stopped that medium in pipe is for a long time to the washing away, corrode of plastic pipe and outer steel pipe end face, and has avoided the coming off of plastic pipe, breakage, has extended the life-span of steel-plastic composite pipe pipe-line system.
[accompanying drawing explanation]
Fig. 1 is the utility model sectional arrangement drawing;
Fig. 2 is the sectional drawing of anti-rust metal lining of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1 to Figure 2, a kind of termination is with the tubing of lining, comprise body 1, at described body (1) pipe end edge, be provided with the anti-rust metal lining (2) embedded in pipe, described anti-rust metal lining (2) outer end is provided with evagination in the flange (201) of described body (1) pipe end.Such structure has prevented that medium in pipe from causing separating, coming off between steel pipe 101 and plastic pipe 102 for a long time to washing away, corroding of body 1 end face connection part, extended the life-span of pipe-line system.
Described body 1 comprises steel pipe 101, is provided with plastic pipe 102 in steel pipe 101, between described plastic pipe 102 and described steel pipe 101 by the hot melt adhesive adhesion.
Described plastic pipe 102 is made for PE or PE-RT.
Be coated with tackiness agent on the surface of contact of described flange 201 and described body 1.
Described tackiness agent is liquid epoxies.
Described anti-rust metal lining 2 is the stainless steel lining.
Described anti-rust metal lining 2 is copper sheathing.
Described anti-rust metal lining 2 wall thickness are 0.4 to 1.0mm.
Described body 1 outer wall has groove 103 near pipe end place's roll extrusion.
Production process of the present utility model is as follows:
1. carry out roll extrusion groove 103 on body 1.
2. the end face coating liquid pressure ring epoxy resins of the body 1 of processing in process step 1.
3. the anti-rust metal lining of corresponding specification 2 is embedded in the body 1 of step 2, and make its flange 201 be close to the end face of body 1.
4. special tool hydraulic collapsible mechanism is stretched in the body 1 that has embedded anti-rust metal lining 2 in step 3, tensioner is carried out in pressurization, and anti-rust metal lining 2 just is close on body 1 inwall.
After machining, antirust lining 2 forms an integral body with body 1 combination, stable connection, firm, applying liquid epoxy resin being close between the flange 201 of body 1 end face and anti-rust metal lining 2, stopped fed sheet of a media in pipe and infiltrated steel pipe 101 with the surface of contact of plastic pipe 102 and steel pipe 101 is produced to corrosion, also stopped plastic pipe 102 separation, come off.
