Description
Technical field
The present invention relates to pyrocondensation pipe fitting technical field, particularly, relate to a kind of modified node method of pyrocondensation pipe.
Background technique
At present, oil and gas industry uses steel pipe to carry out long distance delivery in a large number, needs to use heat shrinking sheet repaired mouth after steel pipe continues, and the material that repaired mouth uses is generally fixing chip pyrocondensation belt, cumbersome during operation, and repaired mouth quality is unstable.For this reason, usually the fixed plate of fixing chip heat shrinking sheet and pyrocondensation belt are prefabricated in the factory and are bonded into tubular thermal shrinkable sleeve pipe to make user easy to operate when using pyrocondensation belt repaired mouth, steady quality.Then, the juncture of current tubular thermal shrinkable sleeve pipe adopts and directly heats pressing mode, and operation easier is large, and fixed precision is not high, and seals is poor, usually there will be the phenomenon of pressing position cracking during use.Thus, there is the problem of cracking phenomena in the pressing position in order to avoid pyrocondensation pipe, and usually adopt the mode of overlap joint to prepare pipe, the material contracting with heat by sheet is rolled into circular tube structure, fixes at lap-joint's employing stitching thread.
But, during existing employing suture lap-joint, owing to not having fixed structure to offset with then suture path, the caliber of the pyrocondensation pipe after sewing up namely can be caused inconsistent, or because of the area sewed up little of causing the pyrocondensation circular tube structure poor stability made.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of modified node method of pyrocondensation pipe, guarantees that structure stability is good under the prerequisite that the pyrocondensation pipe caliber made is consistent.
The present invention's adopted technological scheme that solves the problem is: a kind of modified node method of pyrocondensation pipe, tubulose is rolled into by sheet material contracting with heat, described tubulose comprises 2 lap segments, the sidewall of one of them lap segment is provided with groove, the sidewall of another lap segment is provided with the chimb with groove fit, described lap segment arranged outside has stitching thread groove and full pique are combined, and stitching thread arranged outside has thermal synthesis layer; Described groove is provided with groove at pipe 2 sidewalls axially, and 2 sidewalls of described chimb are provided with the projection coordinated with groove.Existing employing overlapping mode prepares pyrocondensation pipe, the relative position of 2 lap segments is easily caused to be moved when adopting suture lap segment, and then stitching thread is offset, finally cause the caliber of the pyrocondensation pipe be prepared into inconsistent, thus affect the usability of the pyrocondensation pipe made, or reduce to cause structure stability poor because sew up area, material contracting with heat of the present invention is prior art material, the sidewall of described lap segment specifically refers to the side that 2 lap segments of pyrocondensation pipe are relative, described chimb be dimensioned slightly smaller than groove, contractibility due to material contracting with heat makes chimb to insert groove and is clamped in groove, described thermal synthesis layer specifically refers to the structure formed through heating compression heat sealing, described projection can insert in corresponding groove and end and flush with groove, the present invention is by arranging at the sidewall of 2 lap segments the groove and chimb that cooperatively interact respectively, before carrying out lap segment stitching, first chimb is inserted in groove, make projection corresponding inserted in groove and end flushes with groove, by arranging the projection and groove that cooperatively interact, further can not only strengthen the stability of chimb and groove fit, and projection can be sewed up by stitching thread together with groove joint when sewing up, increase and sew up area, avoid the problem of the structure stability difference because sewing up the little pyrocondensation pipe made caused of area, avoid the problem of 2 lap segment generation skews in sewing process, and then adopt stitching thread by chimb and fillister joint altogether and then realize the stitching of 2 lap segments, and then thermal synthesis layer is formed by heating compression heat sealing outside stitching thread, avoid stitching thread to be exposed to outside to be corroded, and the thickness at lap segment place of the present invention does not increase, so, the present invention has the advantage guaranteeing that structure stability is good under the prerequisite that the pyrocondensation pipe caliber made is consistent.
Further, the width of groove in pyrocondensation pipe radial direction is 1/4 ~ 1/3 of sheet material contracting with heat thickness.If it is excessive that the width of groove is arranged, easily cause the sidewall of groove in pyrocondensation pipe radial direction thinner, and then affect the structure stability of pyrocondensation pipe, if what arrange is too small, the thickness that can clamp then corresponding chimb in order to chimb in groove also can be thinning, also can affect the structure stability of pyrocondensation pipe, be the structure stability that 1/4 ~ 1/3 of sheet material contracting with heat thickness can meet pyrocondensation pipe by the width of groove in pyrocondensation pipe radial direction.
Further, stitching thread is provided with 1 ~ 3.Arranging many stitching threads is structure stabilities in order to increase the pyrocondensation pipe made.
Further, sutural wire diameter is 0.2mm ~ 0.5mm.Described wire diameter is sutural diameter, and sutural wire diameter is set to the requirement that 0.2mm ~ 0.5mm meets sutural intensity and toughness.
Further, stitching thread adopts exotic material to make.Pyrocondensation pipe often at high temperature uses, and adopts the stitching thread of exotic material effectively can improve the structure stability of pyrocondensation pipe lap-joint.
Further, exotic material is nylon, polyamide fibre, terylene or aramid fiber.
Further, the thickness of projection is 1/2 ~ 1 of chimb thickness.
To sum up, the invention has the beneficial effects as follows:
1, the present invention is by arranging at the sidewall of 2 lap segments the groove and chimb that cooperatively interact respectively, before carrying out lap segment stitching, first inserts in groove by chimb, and the problem of skew occurs the lap segment avoiding 2 overlap joints in sewing process.
2, the present invention is by arranging the projection and groove that cooperatively interact, further can not only strengthen the stability of chimb and groove fit, and projection can be sewed up by stitching thread together with groove joint when sewing up, increasing and sew up area, avoiding the problem of the structure stability difference because sewing up the little pyrocondensation pipe made caused of area.
