Description
Technical field
The utility model relates to a kind of end structure being applicable to produce flange plastic lining composite steel pipe.
Background technique
Plastic lining composite steel pipe has good intensity and the physical property such as anticorrosive because of it, widely use in fields such as building, oil, mines at present, particularly bigbore flange type lining plastic compound steel Guan Yinqi can bear larger pressure, and in-site installation is convenient and swift, firmly gets the welcome of construction party.
But produce the device of flange-type plastic lining composite steel pipe electrical induction at present, be limited to the restriction that heating collar can not cross flange, plastic lining composite steel pipe can first process by a lot of producers first step, upper flange is welded again after one end is peelled off at plastic lining layer two ends, when welded flange due to high temperature, great infringement can be caused by internal plastics lined pipe.Second step be making one section of same specification lining plastic pipe as repairing use, there is a separating surface in the lining plastic pipe section joint after repairing, can not be combined as a whole reliably, makes the integrity of flange type lining plastic compound steel pipe liner receive destruction.Lining plastic pipe is very easy to stripping and comes off, and reduces adhesive strength and the antiseptic property of flange type lining plastic compound steel pipe, thus limits the application of flange type lining plastic compound steel pipe.
Model utility content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of end structure being applicable to produce flange plastic lining composite steel pipe, optimizes the combination process to liner Plastic Compound Pipe with Flange port further.
The technological scheme that the utility model adopts is, a kind of end structure being applicable to produce flange plastic lining composite steel pipe is provided, mainly comprise sealed cartridge, sealed adapter sleeve, it is characterized in that: described sealed cartridge is horizontal truncated cone shape, vent is provided with in the middle part of sealed cartridge, sealed cartridge is less than the cross section inner circle radius of steel pipe near steel pipe end section radius simultaneously, and sealed cartridge is greater than the cross section exradius of steel pipe away from steel pipe end section radius simultaneously; Described sealed adapter sleeve is made up of steel bushing and mandrel, and described steel bushing is the horizontal cylindric of hollow, steel bushing is provided with the mandrel being no less than.
Further, described sealed cartridge and sealed adapter sleeve are equipped with not sizing coating.
Further, described steel bushing is steel magnetic conductor.
Further, described steel bushing cross section inner circle size and steel tube section inner circle in the same size.
Further, described mandrel cross-sectional sizes is consistent with flange hole size.
Further, described steel bushing is provided with and is no less than a strutbeam, and mandrel is arranged on strutbeam.
Compared with prior art, the beneficial effects of the utility model are: the utility model directly can carry out lining plastic pipe compound to the steel pipe of existing flange, ensure the integrity of plastic lining composite steel pipe, greatly improve the adhesive strength of flange type lining plastic compound steel pipe.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Wherein: 1, steel pipe; 2, lining plastic pipe; 3, heat-fusing glue layer; 4, sealed cartridge; 5, sealed adapter sleeve; 6, not sizing coating; 7, vent; 8, steel bushing; 9, strutbeam; 10, mandrel; 11, flange.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, be applicable to the end structure producing flange plastic lining composite steel pipe for the utility model is a kind of, mainly comprise steel pipe 1, lining plastic pipe 2, sealed cartridge 4, sealed adapter sleeve 5 and flange 11, wherein, flange 11 is arranged at steel pipe 1 one end; Heat-fusing glue layer 3 is provided with between lining plastic pipe 2 and steel pipe 1 institute; Sealed cartridge 4 contacts one end with lining plastic pipe be horizontal truncated cone shape, connecting lining plastic pipe 2 one end is upper bottom surface, the other end is bottom surface, upper bottom surface girth is less than lining plastic pipe 2 inner circle girth, bottom surface girth is greater than steel pipe 1 inner circle girth, be provided with vent 7 in the middle part of sealed cartridge 4, and sealed cartridge 4 skin is provided with not sizing coating 6; Sealed adapter sleeve 5 is made up of steel bushing 8, strutbeam 9 and mandrel 10, wherein, steel bushing 8 is the horizontal cylindric of hollow, cross section is circular, steel bushing 8 cross section annulus size and steel pipe 1 cross section inner circle in the same size, steel bushing 8 is provided with some strutbeams 9 consistent with flange number of openings, and strutbeam 9 is provided with the size mandrel consistent with flange through hole 10, sealed adapter sleeve 5 skin is provided with not sizing coating.
A kind of end structure being applicable to produce flange plastic lining composite steel pipe that the utility model provides, its working method is as follows:
1, flange 11 is welded to one end of steel pipe 1;
2, lining plastic pipe 2 is drawn in steel pipe 1;
3, two ends puts sealed adapter sleeve 5, and sealed adapter sleeve 5 one end is connected with steel pipe 1, and lining plastic pipe 2 gives prominence to sealed adapter sleeve 5 in the reserved about 5-20mm of the other end of sealed adapter sleeve 5;
4, the assembly parts that 1-3 step completes is installed on rotation tube chassis;
5, after installation, send gas-fired tunnel oven to and heat;
6, go out tunnel furnace after having heated to cool;
5, unload from rotation tube chassis the plastic lining composite steel pipe tentatively completed, sealed cartridge 4 also exits in the lump together with cylinder, and then artificial or equipment is past gently again beats mandrel 10 away from steel pipe 1 direction, and sealed adapter sleeve 5 is come off.
6, unnecessary is moulded pipe excision by artificial or equipment, completes whole compound working procedure.
For a person skilled in the art, according to technological scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
