Abstract
The utility model relates to a well net pipeline and gathering and intersite transportation pipeline applied to transporting crude oil in oil field, in particular to a plastic insulating pipe with continuous length. The plastic insulating pipe is composed of a plastic pipe, an insulating layer and a protective covering; the PB or RTP engineering plastic material and the insulating layer for the plastic pipe adopt polyurethane foam material; the protective covering adopts polyethylene jacket layer or is made by TO resin brush coating. The pipeline has corrosion preventive and acid and salt resistant performance; is convenient to maintain and transport; can decrease essential resistance while transporting crude oil, increase the flow speed of the crude oil and the laying speed during construction.
Description
Technical field:
The utility model relates to the oil field and is used for gathering line between conveying crude oil well pattern pipeline and station, especially a kind of plastic, thermal-insulation pipe of continuous length.
Background technique:
Pipeline all adopts the steel insulation pipe between used well pattern pipeline in domestic oil field and station, promptly with the steel pipe pipe of working, implements to be incubated and anticorrosion at outer wall of steel pipe.Because the medium that pipeline is carried between well pattern pipeline and station is the crude oil from underground extraction, crude oil contains a large amount of sewage and various mineral substance, serious to the steel pipe inner wall corrosion, it is defeated to influence proper set, make that pipeline corrosion is serious between well pattern pipeline and station, corrosion failure takes place frequently influences ordinary production, and pipeline is changed frequent, lose hugely, increased cost of production.
The model utility content:
The utility model purpose is in order to overcome above-mentioned shortcoming, and the plastic, thermal-insulation pipe of a kind of continuous length that provides has solved pipeline inner wall corrosion serious problems between well pattern pipeline and station, can prolong gathering line working life, reduces engineering time, reduces cost.
Technological scheme:
For realizing the utility model proposes task, described plastic, thermal-insulation pipe is made up of plastic tube, thermal insulation layer, protective coating.
Described plastic tube adopts polyurethane foam material with PB or RTP engineering plastics material, thermal insulation layer, and protective coating adopts polyethylene clipping layer or TO resin to brush and is made.
The utility model compared with prior art has distinguishing feature:
1, the plastic, thermal-insulation pipe has the advantage of various dielectric corrosions.Soda acid salt and sewage can not play corrosive action to it, can thoroughly solve the problem that the pipeline inner wall corrosion is asked at well pattern pipeline and station with its pipe of working, and improve pipeline working life, as make petroleum pipeline and then need not change pipeline for a long time, reduce and invest.
2, plastic tube inner wall smooth, roughness are 1/7 of steel pipe, therefore can reduce the Crude Oil Transportation friction loss, the power that conveying crude oil is needed significantly reduces, under identical input power condition, flow can improve 20% than the steel pipe of identical latus rectum, reduces operating cost.
3, the thermal conductivity of plastic tube has only 0.2, it is 1/200 of steel pipe, good heat-insulation effect, it is again a kind of thermal insulating material for relative steel pipe, carry the crude oil thermal loss of same temperature to significantly reduce, under equal conditions, because the insulation layer thickness that the plastic, thermal-insulation pipeline needs is littler than the insulation layer thickness that steel pipe needs, can saves Manufacturing material and reduce cost.
4, flexible disk reaches hundreds of rice around joint length, and speed of application is fast, and joint is few, does not need maintenance and inspection when normal operation, reduces maintenance cost.
5, can be in underground burying long-term withstand voltage 8MPa, serviceability temperature-40～85 ℃, and long service life.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Among the figure by plastic tube 1,, 2, thermal insulation layer, 3, protective coating forms.
Embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
Among the figure, plastic tube 1 is to be made with PB or RTP engineering plastics material, has certain flexibility and can coil several meters pipelines to hundred meters joint lengths.
At the outer field thermal insulation layer 2 of plastic tube is that the cylinder shoe that adopts polyurethane foam material to make covers on the surface of plastic tube 1.Protective coating 3 employing polyethylene clipping layers or TO resin are brushed the protective coating at thermal insulation layer 2 outer surfaces.
Above-mentioned plastic tube 1, thermal insulation layer 2 and protective coating 3 have been formed the plastic, thermal-insulation pipe, have corrosion protection, acidproof salt, and be easy to use, can reduce internal resistance during conveying crude oil, increases crude oil flow speed, can be convenient to maintenance and transportation again, can improve laying speed in the construction.
