Description
Technical field
The utility model relates to a kind of internal joint patch device of undercoating pipeline, is applied to the internal joint patch field of pipelines such as oil, chemical industry, gathering line, urban pipe network, especially relates to a kind of internal joint patch lining of undercoating pipeline.
Background technique
At present, along with the rolling development in oil field, oilfield produced fluid progresses into middle and high Water-cut Period, and etching problem is more and more serious in the Quo of Gathering Network.Therefore all adopt the undercoating pipeline in the engineering construction now, to prevent the corrosion of pipeline.But need at the construction field (site) pipeline is coupled together, the heat that welding produces during construction can influence internally coated continuity to easily to the undercoating generation damage of pipeline, therefore need the internal joint patch device be set to it.Therefore the internal joint patch technology of undercoating steel pipe is that the realization of undercoating steel pipe is anticorrosion, the key technology of drag reduction.Existing at present relevant improvement to this technology, as Chinese patent publication number (1080377) " lining steel pipe corrosion-preventing method for welding zone internal wall ", when constructing, this technology on tube wall, punch, inject anticorrosive paint by aperture, and then aperture rivetted and the spot welding shutoff, shortcoming is that body is caused damage, and especially high pressure line never allows, and has also increased workload simultaneously.And for example, Chinese patent publication number (2149540) " interior corrosion-resistanting interpolating port ring ", though this technology is not punched on tube wall, rubber sleeve that adopts or elastic polyurethane cover heat resistance are relatively poor, the metal ring at weld bond place is difficult to every living the high temperature that welding produces, and elastic sleeve will be burnt out.Be pressing between elastic sleeve and the coating reservation face, it is good to be not so good as adhesive effect.And for example, Chinese patent publication number (1099110) " weld of lining pipe sleeve-bonding jointing method ", this technology adopts enamel internal joint patch cover, it is simple to compare top method construction, do not damage pipeline, but the enamel internal joint patch damages easily, will guarantee during installation not collide with, and its surface does not have locating stop piece, is difficult to guarantee the seam crossing of the heat insulating belt of internal joint patch cover at two pipes during installation.
The model utility content
The technical problems to be solved in the utility model provides a kind of advanced more internal joint patch lining, the destruction of when this internal joint patch lining can reduce the field welding construction coating of internal joint patch lining own being caused, guarantee the continuity of internal pipe coating, be not easy again to damage, and installing and locating is convenient during site operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of internal joint patch lining of undercoating pipeline, it comprise the internal joint patch lining tubular body, be coated on the coating on this tubular body surface, its key is to set up backing plate in the described internal joint patch bush structure, backing plate is provided with location piece, is provided with heat insulating belt between the tubular body of backing plate and internal joint patch lining.
Further improving is to be provided with seal ring in the above-mentioned internal joint patch bush structure.
Adopt the beneficial effect that technique scheme produced to be: the internal joint patch lining of this undercoating pipeline is through easy for installation during site operation after the architecture advances, and be not easy during site operation to damage, owing to be provided with a circle heat insulating belt in this internal joint patch bush structure, the damage that in the time of can more effectively preventing on-the-spot pipeline welding the coating of this internal joint patch lining itself is caused, guarantee the continuity of internal pipe coating, can realize that the undercoating steel pipe arbitrarily cuts, improve the weldability of undercoating pipeline; This internal joint patch lining can play positioning action owing to being provided with when location piece is installed, and it can also play fixation to the internal joint patch lining welding back, has guaranteed the quality of product after the welding; This internal joint patch lining is provided with the O RunddichtringO, its effect is to shift the sealer that spreads upon undercoating pipeline inwall onto appointed positions, sealer is filled in the gap between undercoating pipeline and the internal joint patch lining, not only can play seal action, can also guarantee that the internal joint patch lining has steadiness preferably in pipe.
Description of drawings
Fig. 1 is the internal joint patch bush structure schematic representation of this undercoating pipeline;
Fig. 2 be this internal joint patch lining when using with schematic representation after pipeline is connected;
Wherein, 1, the tubular body of internal joint patch lining; 2, backing plate; 3, location piece; 4, heat insulating belt; 5, seal ring; 6, conveyance conduit; 7, welding bead; 8, seal for pipe joints glue.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
A kind of internal joint patch lining of undercoating pipeline, it comprise the internal joint patch lining tubular body 1, be coated on the coating on this tubular body 1 surface, its key is to set up backing plate 2 in the described internal joint patch bush structure, backing plate 2 is provided with location piece 3, is provided with heat insulating belt 4 between the tubular body 1 of backing plate 2 and internal joint patch lining.This internal joint patch lining that is used for the undercoating pipeline can not only guarantee the continuity of undercoating internal pipe coating by structural improvement, and is not easy to damage when installing, and site operation is convenient succinct.The coating of internal joint patch lining sprays with high-level powder coating and special process, fully guarantees the coating product quality.The coating of the heat loss internal joint patch lining that produces in order to prevent to weld adopts special process to adhere to a circle heat insulating belt 4 on the internal joint patch lining, guarantees that coating is not damaged when high-temperature soldering.According to the difference of on-the-spot pipe diameter, can design the product of different size, satisfy different construction requirements.
Be provided with seal ring 5 in the last internal joint patch bush structure.
Preferably, above-mentioned seal ring 5 is the O RunddichtringO.By being set, this O seal ring can shift the sealer that spreads upon tube wall onto appointed positions, sealer is filled in the gap between pipe and the internal joint patch lining, not only can play certain seal action, and can effectively strengthen the stability of this internal joint patch lining in pipeline, the size of this O RunddichtringO is pressed the supporting design of pipeline caliber size.
