Description
Technical field
The utility model is related to oil field gathering line, specifically a kind of inner coating surface gathering and transferring pipeline.
Background technology
Existing oil field gathering and transportation pipeline largely uses interior anti-corrosion mild steel steel pipe, directly welds at the construction field (site)；It is medium and small
The weld seam inner wall of caliber can not implement preservative treatment, and commissure also becomes the weak spot of whole pipeline.Some gathering lines use
Intert polyethylene bushing pipe inside carbon steel piping, the Joining Technology between pipeline is complicated, and difficulty is big, when bushing pipe weld has breakage
When, can not enforcing remedies, make the reduced service life of whole pipeline, while the gathering line construction operation of this structure is existing
, operating environment, condition seriously restrict operation quality, and the heavy workload of site operation personnel, production cycle are long.Also there is collector and delivery pipe
Road uses Nonmetal Anticorrosion Pipeline, but the tube body material brittleness of this pipeline is strong, collides with and is easily damaged.
And carbon dioxide flooding is used in oil field production at present, well produces liquid acidity and improves, and corrosion failure leak case significantly increases
More, the risk that spot corrosion perforation occurs for inner wall of the pipe greatly increases, while oil field requires to reduce production cost, it is desirable that extends pipeline clothes
Use as a servant the time.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of inner coating surface gathering and transferring pipeline, realize pre- in factory
System, live integrated piping construction, shortens the field operation period, gathering line production quality is improved, to meet pipeline active time
Long requirement.
The utility model solve its technical problem the technical solution adopted is that：
A kind of inner coating surface gathering and transferring pipeline, including pipeline body, inner anticorrosioning coating, pipeline body are mild steel steel pipe,
Pipeline body both ends are welded with stainless steel pipe nipple, stainless steel pipe nipple and pipeline body be isometrical, etc. wall thickness, pipeline body and stainless steel
Pipe nipple inner wall sprays inner anticorrosioning coating respectively, constitutes gathering line unit；It is welded by stainless steel pipe nipple between gathering line unit
It connects in succession, constitutes whole gathering line.
Using the utility model of above-mentioned technical proposal, compared with prior art, advantage is：
Gathering line unit may be implemented prefabricated in factory, not only ensure that the good welds performance of field joint, but also reduce
The task difficulty of live whole gathering line construction, shortens the field operation period, improves the production quality of gathering line,
To extend the service life of gathering line.
Further, the utility model preferred embodiment is：
Inner anticorrosioning coating is clinkery epoxy powder erosion resistant coating.
Stainless steel pipe nipple is the welding section of no inner anticorrosioning coating at pipe port 50mm.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment；
In figure：1- stainless steel pipe nipples, 2- inner anticorrosioning coatings, 3- pipeline bodies.
Specific implementation mode
The utility model is further elaborated with reference to the accompanying drawings and embodiments.
Referring to Fig. 1, a kind of inner coating surface gathering and transferring pipeline, by stainless steel pipe nipple 1, inner anticorrosioning coating 2,3 structure of pipeline body
Mild steel steel pipe is used at, pipeline body 3, stainless steel pipe nipple 1 uses 316L, stainless steel pipe nipple 1 and pipeline body 3 be isometrical, etc.
Wall thickness, welding and pipeline body 3 and stainless steel pipe nipple 1 of completion 3 both ends of pipeline body with stainless steel pipe nipple 1 in factory
Inner surface sprays inner anticorrosioning coating 2, and inner anticorrosioning coating 2 is clinkery epoxy powder erosion resistant coating, is equipped and is sprayed by hot-spraying technique
It applies, stainless steel pipe nipple 1 is welding section at pipe port 50mm, does not spray inner anticorrosioning coating 2, thus pre-formed gathering line
Unit.
Prefabricated gathering line unit is transported to scene in factory, by the welding between stainless steel pipe nipple 1, is connected as entirety
Gathering line.Welding procedure is simple between gathering line unit, is not required to make the i.e. certifiable connector corrosion resistance of internal joint patch anti-corrosion
Energy.
The above is only the preferred feasible embodiment of the utility model, not thereby limits to the power of the utility model
Sharp range, it is all with equivalent structure variation made by the utility model specification and accompanying drawing content, it is both contained in the utility model
Interest field within.
