The invention relates to a long-distance continuous lining tube and short metal tube combination device which comprises a plurality of short metal tubes on an outer layer, a plurality of lining tubes on an inner layer, and connecting hoops, wherein the short metal tubes are connected end to end; female threads are arranged in the connecting hoops; male threads are arranged at the two ends of each short metal tube; the end parts of the two adjacent short metal tubes are screwed in the connecting hoops and occluded with the female threads of the connecting hoops through the male threads; the end surfaces of the two short metal tubes are closely butted. The invention further provides a manufacturing method of the combination device. According to the combination device, the problems of difficult aligning, easy deviating and jamming or scratching of lining tubes caused by welding pipelines can be solved and the short metal tubes can be closely butted; meanwhile, a welding technology is not adopted, so that the pipeline temperature is lower, the traction operation can be performed section by section, the defect of long-distance traction is overcome, the trouble and labor are saved, and the working efficiency is greatly improved.
Description
Technical field
The invention belongs to pipe-line equipment field, relate to a kind of long distance internal lining pipe and short metal tube integrated apparatus and preparation method continuously.
Background technique
The internal lining pipes such as metallic conduit plastic lining, rubber have become the comparatively common pipelines of industry such as municipal administration, oil, chemical industry, the method of construction of current this pipeline is mainly first short metallic conduit to be welded to connect into long-distance pipe one by one, then by the mode of traction, from one end, liner pipe is drawn to the other end, by various treatment process, liner pipe and metallic conduit are combined into one again, complete pipeline construction.There is following shortcoming in this form of construction work: the one, be welded to connect the engineering time needing long, and the weld bond that simultaneously will align when welding if there is some deviations, is easy to block in this when penetrating internal lining pipe.The 2nd, because the pipe temperature that welding causes is too high, after can only waiting welding all to complete, pipe temperature lowers and could draw internal lining pipe and pass through, while therefore constructing, must use long apart from pulling equipment, and the drafting tool of the flexibility or rigidity that when traction used will first in all sorts of ways from one end and arrives the other end through the metallic conduit that has welded growth distance, and then be connected with the continuous internal lining pipe of long distance, with the continuous internal lining pipe of the long distance of pulling equipment traction, through being welded into the metal tube of long-distance pipe, complete poling construction.Therefore, need to solve the problems referred to above.
Summary of the invention
The object of this invention is to provide a kind of long distance internal lining pipe and short metal tube integrated apparatus continuously, solve the internal lining pipes such as metal current pipe lining plastics, rubber and easily cause deviation, and need long distance traction, the inconvenient problem of constructing.
Second object of the present invention is to provide the preparation method of the continuous internal lining pipe of above-mentioned long distance and short metal tube integrated apparatus.
The present invention is achieved through the following technical solutions:
One, long apart from continuous internal lining pipe and a short metal tube integrated apparatus, comprise the internal lining pipe of outer field many short metal tubes and internal layer, many short metal tube end-to-ends; Also comprise box cupling, there is box thread described box cupling inside, and there is respectively male thread at short metal tube two ends, and the end of two adjacent short metal tubes screws in box cupling and the box thread phase interlock with box cupling by male thread, and the closed butt joint of two short metal tube end faces.
Further, the male thread length sum at described short metal tube two ends is than the large 10%-15% of box thread length in box cupling.
Further, the box thread in described box cupling is connected respectively 50% with the male thread of the short metal tube of both sides.
Two, the above-mentioned continuous internal lining pipe of long distance and a preparation method for short metal tube integrated apparatus, the method comprises the following steps:
(1) end of first short metal tube is screwed in to box cupling;
(2) with drafting tool, connect internal lining pipe, through first short metal tube;
(3) drafting tool is passed to second short metal tube;
(4) second short metal tube screwed in to the box cupling that has connected first short metal tube, until the closed butt joint of two short metal tube end faces;
(5) with drafting tool traction internal lining pipe, pass second short metal tube, by that analogy.
Adopt the good effect of technique scheme: the present invention can overcome the alignment that is not easy that welded pipe line brings, and easily causes deviation, and the problem that causes internal lining pipe to block or scratch, can realize the closed butt joint between short metal tube; Meanwhile, owing to not adopting welding technique, so pipe temperature is lower, can sectionally carry out towage, has overcome the disadvantage of long distance traction, save trouble and labor, and operating efficiency improves greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 short metal tube, 2 internal lining pipes, 3 box cuplings.
Embodiment
Below in conjunction with embodiment, technological scheme of the present invention is done to further restriction, but should not be construed as limitation of the present invention:
embodiment 1
Long distance is internal lining pipe and a short metal tube integrated apparatus continuously, comprises the internal lining pipe 2 of outer field many short metal tubes 1 and internal layer, many short metal tube 1 end-to-ends.Also comprise box cupling 3, there is box thread described box cupling 3 inside, there is respectively male thread at short metal tube 1 two ends, and the end of two adjacent short metal tubes 1 screws in box cupling 3 and the box thread phase interlock with box cupling 3 by male thread, and two short metal tube 1 end face closed butt joints.By being threaded, substitute original welding, greatly improved construction precision, can prevent that deviation from appearring in weld bond, caused internal lining pipe easily block or scratch.
The male thread length sum at short metal tube 1 two ends is than the large 10%-15% of box thread length in box cupling 3, and object is that after guaranteeing to connect, the end face of two short metal tubes can closed butt joint and seamless.
Box thread in box cupling 3 is connected respectively 50% with the male thread of the short metal tube 1 of both sides, even if flat mother buckle threaded collar joint is partial to any side, also can guarantee the end face closed butt joint of two short metal tubes.
embodiment 2
A preparation method who grows the continuous internal lining pipe of distance and short metal tube integrated apparatus, the method comprises the following steps:
(1) end of first short metal tube is screwed in to box cupling;
(2) with drafting tool, connect internal lining pipe, through first short metal tube;
(3) drafting tool is passed to second short metal tube;
(4) second short metal tube screwed in to the box cupling that has connected first short metal tube, until the closed butt joint of two short metal tube end faces;
(5) with drafting tool traction internal lining pipe, pass second short metal tube, by that analogy.
Take HDPE(high density polyethylene (HDPE) below) internal lining pipe and short metal tube are example explanation to long distance continuously.
HDPE(high density polyethylene (HDPE)) external diameter 60mm, internal diameter 50mm, joint length 500m.Short metal tube is selected 45# carbon steel tube, internal diameter 62mm, external diameter 73mm, joint length 10m, two end male thread M72 * 3.Box cupling external diameter 90mm, length 100mm.Drafting tool is selected flexibility or rigidity draw-bar 12m-15m, and external diameter is less than 40mm.
