Abstract
The invention discloses a special petroleum pipe used during oil production operation. The special petroleum pipe comprises an outer pipe and a liner pipe, and is characterized in that the inner wall of the outer pipe is subjected to sand blasting treatment to have an anchor pattern degree, chamfers are arranged at the inner edges of two ends of an opening of the outer pipe, the inner wall of the outer pipe and the end surfaces of the outer pipe are in smooth transition, the liner pipe is directly lined on the inner wall of the outer pipe, two ends of the liner pipe are turned outwardly and are manufactured on the end surfaces of the outer pipe in a turned manner to form flat end surfaces of a composite pipe, and the diameters of the outwardly turned portions of the liner pipe are matched with the diameter of the outer pipe. The special petroleum pipe has the advantages of simple structure, high bonding strength, abrasion resistance and corrosion resistance.
Description
Technical field
The present invention relates to a kind of oil pipes used in oil producing operation.
Background technology
In petroleum industry, the Intensity Design of oil pipes is wanted can the requirement of ply stress and construction operation contentedly, prior art is general all with the seamless of high-strength material or straight-seam pipes, make through series of process such as modified, shaping, car buttons and form steel pipe, or the inwall of oil pipes such as PROCESS FOR TREATMENT such as application steel pipe coating and gluing glass fiber reinforced plastic etc., it is made to possess the technical performance of anticorrosion, wax control and antiscale, but these oil pipes not only complex manufacturing technology, and inwall is not wear-resistant, in oil producing operation, stand the reciprocal wearing and tearing of sucker rod and centralizer, very easily damage.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the oil pipes used in oil producing operation providing a kind of practicality, and structure is simple, bond strength is high and wear-and corrosion-resistant.
For reaching above-described object, a kind of oil pipes used in oil producing operation of the present invention takes following technical scheme:
A kind of oil pipes used in oil producing operation, comprise outer tube and bushing pipe, it is characterized in that, described outer tube wall is formed with anchor line degree through blasting treatment, and the inside edge at outer tube opening two ends has chamfering, outer tube wall and its end face rounding off, described bushing pipe directly serves as a contrast on the inwall of outer tube, turns up in its two ends, and the two ends of bushing pipe are rebuild or renovate on the end face of outer tube, form smooth clad pipe end face, bushing pipe turn up diameter and outer tube diameter suitable.
Described outer tube is steel pipe, and bushing pipe is the plastic pipe of Wear-resistant corrosion-resistant.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
Outer tube wall of the present invention has the anchor line obtained through sandblasting Shot Blasting, like this when bushing pipe is directly served as a contrast on outer tube wall, bushing pipe temperature distortion will embed there is certain depth anchor line among, after cooling, both just can firmly and closely combine, thus form the clad pipe of high strength, guarantee that outer tube and bushing pipe operationally can not depart from mutually, because bushing pipe not only has anticorrosion, wax control and anti-scaling property, also have very high anti-wear performance concurrently, therefore this clad pipe has very high abrasion resistance compared with conventional petroleum dedicated pipe, in the operation of Bian oil, the reciprocal wearing and tearing standing sucker rod and centralizer are not fragile yet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is end face enlarged diagram of the present invention.
Detailed description of the invention
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, a kind of oil pipes used in oil producing operation of the present invention, outer tube 1 is steel pipe, the inside edge at its opening two ends has chamfering, i.e. inwall and end face rounding off, inwall is formed with anchor line through blasting treatment, bushing pipe 2 is wear-resisting for having, the plastic pipe of the property such as anticorrosive, its wall thickness integration engineering technical requirements, bushing pipe 2 directly serves as a contrast on the inwall of outer tube 1, its two ends are rebuild or renovate on the end face of outer tube 1, outer tube 1 and bushing pipe 2 thus strong bonded form the clad pipe of high strength, the two ends that bushing pipe 2 turns up form smooth clad pipe end face.In actual manufacture process, the direct combination of outer tube 1 and bushing pipe 2 can following three kinds of technical scheme: the A of Bian, the steel contraction practice, realize mainly through following processing step: a, first sandblasting Shot Blasting is carried out to oil pipes inwall, make it reach the anchor line degree of technological requirement; B, by process after petroleum pipeline engineering stove heating make it expand into technological requirement at a set temperature after come out of the stove; C, while hot the plastic pipe made is advanced in steel pipe, after steel pipe cooling meat, realize the compound with plastic liner; D, two ends plastic pipe are rebuild or renovate, and complete produced with combination.B, hot melt composite algorithm, realize mainly through following processing step: a, first carry out blasting treatment to oil pipes inwall, makes it reach the anchor line degree of technological requirement; B, will give in oil pipes that the plastic pipe that first makes advances after process; C, enter to rotate engineering stove be warmed to design temperature make plastic pipe melt lining adhere to dedicated pipe inwall formed clad pipe; D, two ends flange and finishing, complete produced with combination.C, flow serve as a contrast swollen method, realize mainly through following processing step: a, first by steel pipe inner wall blasting treatment, make it reach the anchor line degree of technological requirement; B, employing special process make bushing pipe cold treatment undergauge reach technological requirement; C, the plastic pipe after undergauge to be inserted rapidly in steel pipe; D, to enter engineering stove persistently overheating to technological temperature, makes steel pipe heat expansion, and plastic liner produces memory distortion (expanded radially) and realizes and the firm compound of steel pipe under temperature action; After e, cooling of coming out of the stove, two ends bushing pipe flange finishing, completes making.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection scope of the present invention.
