Description
Technical field
The utility model belongs to Double-metal pipe production technical field, and in particular to a kind of conduit stack mounted welder.
Background technique
Petroleum pipeline is the important transfer unit of oil and gas industry, and bimetal metallurgy multiple tube is corrosion-resistant, at low cost,
It is the best selection of Crude Oil Transportation.Pipeline supply of material length is generally 6~12m, because strength check and project cost problem, double
The outer layer carbon steel pipe of metal compounded pipe is in welding without additional thickening.In homogeneous tube inner wall overlaying, high temperature makes pipeline
The strength of materials reduces, and pipeline is generally horizontal positioned, the easily-deformable bending of pipeline under the influence of gravity, welding quality after pipe bending
And bad stability, for small-bore pipeline, welding gun can not pass through after bending, need that whole root canal could be completed through multiple shaping
The welding in road.
It is directed to this kind of pipe deforming problem at present, generally using the pipeline of specification bigger than pipeline to be welded, on pipeline uniformly
Bolt is set, ventilation hole is formed by cutting pipeline, reduces weld interpass temperature using air cooling or air cooling plus water cooling in welding.
Its there are the problem of have: 1) assemble and to remove tooling difficult.After welding, it is inclined to due to the deformation of pipeline and is limited by bolt
System, it is necessary to which pipeline could be extracted out by back-outing bolt completely, remove tooling.2) tooling damages pipe surface.When pipeline welding
Very big stress is formed between pipeline and bolt, pipeline has the tendency that radially bending and axial shortening, is pressed in pipe since bolt screws
Road surface, it is easy to scratch and weigh wounded pipe surface.According to the relevant criterion of oil pipeline, pipe surface shortcoming is greater than 0.8mm
It is considered as defect, and does not allow to repair, this will lead to a large amount of scrap of the product.
Therefore it is simple to be badly in need of providing a kind of installation and removal, working efficiency can be improved, prevent pipe deforming, reduce unqualified
The conduit stack mounted welder of product.
Utility model content
The purpose of this utility model is the deficiency for existing conduit stack mounted welder, and it is simple to provide a kind of installation and removal,
Working efficiency can be improved, prevent pipe deforming, reduce the conduit stack mounted welder of rejected product.
The utility model provides the following technical solution:
A kind of conduit stack mounted welder, the connector including several tooling ontologies and the connection tooling ontology, the tooling
Ontology is equipped with several groups ventilation hole and fastening bolt, and the connector is made of two symmetrical semicircular rings, and two described half
Annulus is fastened on the adjacent tooling ontology and both ends are bolted.
Preferably, fastening bolt quantity described in every group is 4, is evenly distributed on the circumferencial direction of the tooling ontology.
Preferably, the end of the fastening bolt is equipped with bolt chamfering, and the fixed fire- resistance cloth in the fastening bolt end is described
Fastening bolt screw-in holds out against the restriction conduit on pipeline and deforms, described when pipeline has the tendency that radially bending and axial shortening
Fastening bolt chamfering can prevent its end from scratching pipe surface, the relative movement that workpiece deformation generates when welding pipeline with it is described
Between the fire- resistance cloth of fastening bolt end, the fire- resistance cloth quality is softer, can reduce the fastening bolt to the pressure of pipe surface
Wound and scuffing.
Preferably, the ventilation hole is rectangle, and ventilation hole number described in every group is two, and cooling air is from institute when welding
It states ventilation hole to blast, be gas-cooled in the pipeline outer wall.
Preferably, the two sides of the semicircular ring are equipped with lug, and the lug is equipped with the screw thread matched with the bolt, lead to
It crosses and screws the bolt, move toward one another two semicircular rings to the fixed adjacent tooling ontology.
The beneficial effects of the utility model are:
(1) tooling ontology is equipped with ventilation hole, can blast cooling air in welding, carry out air cooling drop from pipe outer wall
The temperature of low welding region, to realize control welding deformation and layer chemical component.
(2) tooling ontology is equipped with fastening bolt, restriction conduit can deform in the welding process, reduce rejected product,
Bolt end is chamfering, and when pipeline has the tendency that radially bending and axial shortening, bolt chamfering can prevent bolt end from scratching
Pipe surface, the relative movement that workpiece deformation generates in the fixed fire- resistance cloth of bolt end, welding occur soft with quality in pipeline
Between soft fire- resistance cloth, to realize the damage for mitigating pipe surface.
(3) several tooling ontologies are inserted in pipeline, are connected using connector, when disassembly, the bolt of tooling ontology are unscrewed, pine
The bolt of follower link can quickly extract whole section of tooling ontology out, and the other positions of pipeline are still limited by tooling, will not be dashed forward
Right deformation is hurted sb.'s feelings, and staged operation like this can quickly remove all tooling ontologies.
(4) relative to integrated tooling, the method removed using segmentation, effectively prevent postwelding due to pipe deforming stress and
It is not easy the problem of taking out from tooling.
(5) the utility model installation and removal are simple, and working efficiency can be improved, and prevent pipe deforming, reduce rejected product.
