Abstract
The utility model provides an inside lining pipe end strutting arrangement of portion, support external diameter and inside lining internal diameter of pipe looks adaptation, support front position are equipped with ball support and ball backup pad, and ball support and ball backup pad internally mounted have the roll ball and contact with the parent tube inner wall, the ball support passes through both sides bolt connection with the support, install the jump ring on the support, the terminal surface and the ball backup pad terminal surface in close contact with of jump ring, the invention utilizes freely the roll characteristics of zero friction of ball, bushing pipe and the same axle center of parent tube in the ball can roll and make during the poling, and the bushing pipe can not contact with the parent tube in the whole process, has guaranteed that the compound pipe connector of bimetal touches the smooth finish of interfacial, and sliding friction takes place and makes the shortcoming of inner wall fish tail for inside lining pipe end portion and the contact of parent tube inner wall when overcoming the compound pipe poling of present bimetal, has simple structure, convenient to use, advantage that the reliability is high, with low costs.
Description
Technical field
The present invention relates to composite bimetal pipe technical field, be specifically related to a kind of internal lining pipe end support device.
Background technique
In recent years along with expanding economy, energy demand sharp increase, international, domestic all in the dynamics strengthening recover petroleum, rock gas.Pipe-line obtains develop rapidly as a kind of economy of oil and natural gas, long distance delivery instrument safely, uninterruptedly.Traditional tubing is not suitable for the conveying of high corrosion oil gas gradually, and adopts corrosion resisting alloy cost intensive, and therefore composite bimetal pipe arises at the historic moment.Composite bimetal pipe is made up of the metal tube of two kinds of unlike materials: base tube is high strength carbon steel tubing, inside liner is corrosion resistance alloy, formed by various distortion and interconnection technique between tube layer and combine closely, tubing had both had good intensity and corrosion resistance, and cost is low, obtain the extensive accreditation of domestic and international market, development rapidly.
In composite bimetal pipe manufacture process, need interliner alloy pipe through carbon steel base tube, due to interliner alloy pipe external diameter slightly less than carbon steel base tube internal diameter (generally at 3-8mm), so interliner alloy tube end is understood and carbon steel base tube contact internal walls generation sliding friction owing to conducting oneself with dignity in poling process, cause carbon steel base tube inwall to be formed to scratch, even Remaining debris between two pipes, has had a strong impact on the quality of composite bimetal pipe.
Summary of the invention
In order to overcome above-mentioned prior art Problems existing, the object of the present invention is to provide a kind of internal lining pipe end support device, the shortcoming that during to overcome existing composite bimetal pipe poling, internal lining pipe end and base tube contact internal walls generation sliding friction make inwall scratch, ensure that the forming quality of composite bimetal pipe, there is the advantage that structure is simple, easy to use, reliability is high, cost is low.
In order to achieve the above object, technological scheme of the present invention is:
A kind of internal lining pipe end support device, comprise support 1, support 1 external diameter and internal lining pipe 8 internal diameter suitable, support 1 front position is equipped with ballframe carriage 4 and ball dunnage 5, ball dunnage 5 is arranged between ballframe carriage 4 and support 1, and ballframe carriage 4 and ball dunnage 5 inside are provided with can Free-rolling ball 3 and rolling ball 3 and base tube 7 contact internal walls; Ballframe carriage 4 is connected by both sides latch 6 with support 1; Support 1 is provided with jump ring 2, the end face of jump ring 2 and ball dunnage 5 end face close contact.
Described support 1 front end is the conical surface, and convenient loads in internal lining pipe 8.
Internal lining pipe end provided by the invention support device, can to ensure in poling process internal lining pipe all the time with base tube concentric, reach internal lining pipe and base tube contactless object all the time, substantially increase composite bimetal pipe quality, structure is simple, is convenient to actual industrial production and uses.
Accompanying drawing explanation
Figure 1A is structural representation of the present invention,
Figure 1B is end view.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
With reference to accompanying drawing, a kind of internal lining pipe end support device, comprises support 1, and its front end is the conical surface, support 1 external diameter and internal lining pipe 8 internal diameter suitable, facilitate support 1 to load in internal lining pipe 8; Support 1 front position is equipped with ballframe carriage 4 and ball dunnage 5, and ball dunnage 5 is between ballframe carriage 4 and support 1; The ball 3 of some is arranged on ballframe carriage 4 and ball dunnage 5 is inner, and ball 3 can Free-rolling, and with base tube 7 contact internal walls, ensure that internal lining pipe 8 and base tube 7 exist gap contactless; Ballframe carriage 4 is connected together by both sides bearing pin 6 with support 1; Support 1 is provided with jump ring 2, the end face of jump ring 2 and ball dunnage 5 end face close contact, carry out spacing to ball dunnage 5.
Working principle of the present invention is:
The present invention utilizes ball Free-rolling frictionless feature, make internal lining pipe 8 in poling process all the time with base tube 7 inwall without friction, ensure that the degree of finish between composite bimetal pipe surface of contact, improve the forming quality of composite bimetal pipe.
Before composite bimetal pipe poling, the ball 3 of some is loaded in ballframe carriage 4, then ball dunnage 5 is loaded ballframe carriage 4, loaded on support 1 again, jump ring 5 is contained on support 1, and with bearing pin 6, ballframe carriage 4 is connected with support 1, finally end support device is contained on internal lining pipe end.During poling, ball can roll and make internal lining pipe and base tube concentric, and whole process internal lining pipe can not contact with base tube, ensure that the degree of finish between composite bimetal pipe surface of contact.
