Seeing figures.1.and.2, be fixedly connected with joint 2 at the end treating lined steel pipe 1, wherein, anticorrosive coat 3 is tied for integral type
Structure, is formed after two joints 2 welding and has the heat-insulating and sealing chamber 4 of annular space, weld bond 5 by heat-insulating and sealing chamber 4 and anticorrosive coat 3 every
From, joint 2 is additionally provided with the hole 6 connected with heat-insulating and sealing chamber, is fixed with sealing blocking 7 in hole 6, sets in heat-insulating and sealing chamber 4
There are the charges 8 filled by hole 6.After two joints 2 have welded, in heat-insulating and sealing chamber 4, fill charges 8 by hole 6,
Seal such as glue class etc., then by sealing blocking 7 tight closures, prevent from revealing.
After welding, weld bond 5 is isolated with anticorrosive coat 3 by heat-insulating and sealing chamber 4, is possible not only to make solder joint remote by this structure
From anticorrosive coat 3, and isolated by heat-insulating and sealing chamber 4, can effectively prevent the heat damages anticorrosive coat 3 during welding, and
Heat non-rectilinear transmits, and can reduce conduction of heat, prevents from further damaging anticorrosive coat 3, so not only increases the anti-corrosive properties of pipeline
Energy and sealing property, also improve the linking intensity at pipe joint, to meet at sufficiently large intensity of pressure lower seal simultaneously.
Embodiment one:
Joint 2 is fixedly installed on the outer surface of pipeline body 1, and described anticorrosive coat 3 is arranged on the interior of adjacent two pipeline bodies
On wall.Wherein, joint includes connecting portion 10 that internal diameter is identical with pipeline body 1 external diameter and the insulation part more than connecting portion diameter
11, described insulation part 11 be arranged in parallel with pipeline body 1, and the insulation part 11 of adjacent two joints welds together.So pass through
The welding of two insulation part 11 can make solder joint away from anticorrosive coat 3, and is isolated by heat-insulating and sealing chamber 4, can effectively prevent
Heat damages anticorrosive coat 3 during welding, and the transmission of heat non-rectilinear, can reduce conduction of heat, prevents from further damaging anticorrosive coat
3, so not only increase antiseptic property and the sealing property of pipeline, also improve the linking intensity at pipe joint simultaneously, with
Meet at sufficiently large intensity of pressure lower seal.
The end of adjacent two pipeline bodies 1 is provided with the liner flange 9 extended along anticorrosive coat 3, adjacent two joints 2 interior
The corresponding contact of lining flange 9, forms the heat insulation close of annular by liner flange 9 and the insulation part 11 of two joints 2 and pipeline body 1
Envelope chamber 4.It is possible to prevent when filling charges 8 in heat-insulating and sealing chamber 4 to leak to anticorrosive coat by the corresponding contact of liner flange 9
In 3, improve sealing.
When specifically installing, pipeline body 1 is first welded with joint 2, makes the inwall of joint 2 and the outer surface of pipeline body 1
Fixing, then the inwall upper berth at pipeline body 1 sets anticorrosive coat 3, and outwards overturns formation liner in the end of pipeline body 1 and turn over
Adjacent two joints 2 are alignd by limit 9, make the liner flange 9 extruding contact of pipeline body 1 end, and weld insulation part 11
Connecing, wherein, weld bond 5 is that the welding of adjacent two insulation part 11 is formed, after weld, insulation part 11 and pipeline body 1 formed every
Heat seal chamber 4, is filled charges 8 in heat-insulating and sealing chamber 4 by hole 6, seals such as glue class etc., then blocked by sealing
7 plugging holes 6, prevent from revealing.
Embodiment two:
With reference to Fig. 2, above-mentioned joint 2 is fixed on the internal diameter of the end of pipeline body 1, the internal diameter of joint 2 and pipeline body 1
Unanimously, pipeline body 1 is equipped with anticorrosive coat 3 on the inwall of joint 2, anticorrosive coat 3 for be arranged on interior tube inner surface and end face and
Adjacent two joints 2 are welded by the continuous structure of inner surface of pipeline, can be coupled together by two pipeline bodies 1.
Joint includes being made up of inner core 21 and the urceolus 22 coaxial with inner core 21, and one end of urceolus 22 is connected with inner core 21
Connecing, the urceolus 22 of the joint of adjacent two pipelines welds together, and forms annular heat annular seal space between inner core 21 and urceolus 22
4.Owing to urceolus 22 is away from anticorrosive coat 3, solder joint so can be made away from anticorrosive coat 3, do not damage anticorrosive coat 3, it is ensured that antiseptic effect.
Meanwhile, anticorrosive coat 3, when laying, can extend at the inner core 21 of adjacent two joints 2 and form liner flange
9, i.e. two liner flange 9 wrap the end face of inner core 21, and liner flange 9 correspondence of adjacent two joints 2 contacts, and i.e. two
While the inner core 21 of individual joint 2 is shorter than urceolus 22, so welding urceolus 22, the liner flange 9 between two inner cores 21 can be made
It is in close contact, prevents from leaking in anticorrosive coat 3 when filling charges 8 in heat-insulating and sealing chamber 4, improve sealing.
Wherein, the axial cross section of described inner core 21 and urceolus 22 is U-shaped or H-shaped structure.Certainly, can as required, also
Can be other structures that can realize buffer action.
From the foregoing, it will be observed that the weld bond 5 of joint 2 is away from anticorrosive coat 3, and the structure with isolating seal chamber 4 belongs to protection
Within the scope of.
During construction, scene is treated lined steel pipe 1 and is first welded with joint 2, and the inwall making joint 2 is put down with the inwall treating lined steel pipe 1
After the most fixing, set anticorrosive coat 3 on the inwall upper berth treating lined steel pipe 1 and joint 2, when laying, owing to internal lining pipe 15 is through too much
After the isometrical compression of level, temporarily reduce the external diameter of bushing pipe, be so wound around after cylinder 12 is wound around by internal lining pipe and transport to job site,
Then in internal lining pipe 15 is drawn in by steel wire rope and to be treated lined steel pipe 1 by traction machine 14, when internal lining pipe 15 is completely into treating lined steel pipe 1
Through after a period of time, internal lining pipe 15 slowly recover and with the former inwall treating lined steel pipe 1 combining tightly, the scheduled time
The end of inner core 21 is outwards overturn formation liner flange 9 the most again, by adjacent two joints alignment, makes the liner of inner core 21 end
Flange 9 extruding contact, and urceolus 22 is welded, wherein, weld bond 5 is that two urceolus 22 welding are formed, after having welded, outward
Between cylinder 22 and inner core 21 and two inner cores 21, the liner flange 9 of extruding forms heat-insulating and sealing chamber 4, by hole 6 to heat-insulating and sealing
Fill charges 8 in chamber 4, seal such as glue class etc., then by sealing blocking 7 plugging holes 6, prevent from revealing.
This utility model is rational in infrastructure, can reduce conduction of heat by the heat-insulating and sealing chamber 4 of annular, can effectively prevent anticorrosion
The damage that causes of layer, sealing and antiseptic property are good, can effectively prevent pipe leakage, extend pipeline service life, and can subtract
Little entire outer diameter, it is simple to construction.
This utility model is not limited to above-mentioned embodiment, in the ken that those skilled in the art are possessed,
Can also make a variety of changes on the premise of without departing from this utility model objective, the content after change still falls within this utility model
Protection domain.
