Abstract
A new type glass steel protective pipeline used mainly to resolve the issue that the poor rigidity of the pipeline used by the existing oil fields leads to the pipeline is easily damaged by the outside force, which is characterized in that a basic pipe (3) is made of steel, and the inner wall of the basic pipe has a protecting coating; the outer wall of the basic pipe is in turn combined with a polyurethane insulating layer (2) and a glass steel protective layer (1). Thanks to the new type glass steel protective pipeline takes a reinforced plastics alloy layer as the pipe layer of the outer wall of the transport pipeline, therefore, the utility model has the advantages of: anti-aging; high strength; tensile resistance and better insulation performance.
Description
Technical field:
The utility model relates to a kind of device that is used for conveyance fluid on the oil field, especially relates to a kind of pipeline that adopts glass fibre reinforced plastics as external protection.
Background technique:
In oil field operation, often need carry at a distance some fluids.Existing conveyance conduit all is to adopt with common steel pipe as parent tube usually, twines thermal insulating material outside steel pipe layer by layer, covers with things such as iron sheets on thermal insulating material then again.The problem that conveyance conduit exists under this pattern is: the rigidity and the hardness of whole pipe are very poor, and outer attached iron sheet is easy to be damaged under external force, causes thermal insulation property destroyed, even the normal conveying of damage pipeline.
The model utility content:
In order to solve existing oil field pipeline poor rigidity commonly used, impaired problem easily under external force; the utility model provides a kind of new glass fibre reinforced plastic protection pipeline; this kind glass fibre reinforced plastics protection pipeline is the outer wall pipe layer of delivering pipe with the glass-steel reinforced plastic alloy-layer, has the characteristics of anti-aging, high strength, stretch-proof, good heat insulating.
The technical solution of the utility model is: this kind glass fibre reinforced plastics protection pipeline; constitute by parent tube, thermal insulation layer and anticorrosive coat, external protection; wherein said parent tube is a steel pipe; the parent tube inwall is compounded with anticorrosive coat; anti-corrosion material adopts the S401 preservative, and the parent tube outer wall is compounded with polyurethane insulation coating and glass fibre reinforced plastics protective layer successively.Wherein the glass fibre reinforced plastics protective layer adopts the glass-steel reinforced plastic alloy, and its structure is the plastic alloy inboard, and outside multi-lay winding glass fibre reinforced plastics strengthens.
The utlity model has following beneficial effect: after adopting this programme; owing to will have the outer protective tube of the glass-steel reinforced plastic alloy of high strength, anti-folding, resistance to deformation as pipeline; the polyurethane that thermal insulation property is stable is as the thermal insulation pipe layer; the impaired under external force possibility of pipeline is reduced greatly, and strengthened its thermal insulation property.
Description of drawings:
Fig. 1 is a structure cut-away view of the present utility model.
1-glass fibre reinforced plastics protective layer among the figure, 2-polyurethane insulation coating, 3-parent tube.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in Figure 1 is the structure sectional view of this kind glass fibre reinforced plastics protection pipeline, and its basic structure is for being parent tube 2 with the steel pipe, is compounded with anticorrosive coat at the inwall of parent tube 2, and anti-corrosion material adopts S401 as preservative.The outer wall of parent tube 2 is compounded with polyurethane insulation coating 2 and glass fibre reinforced plastics protective layer 1 successively.Wherein glass fibre reinforced plastics protective layer 1 adopts the glass-steel reinforced plastic alloy; its structure is the plastic alloy inboard; outside multi-lay winding glass fibre reinforced plastics strengthens; have extremely strong corrosion resistance, anti-folding stretch-resistance; and also has thermal insulation property preferably; therefore adopt it to do outer protective tube, can overcome the outer protective bulkhead poor rigidity of existing pipeline, shortcoming such as easy impaired, improved the whole pipe outer force bearing strength greatly.
Claims (1)
1, a kind of glass fibre reinforced plastics protection pipeline comprises parent tube (3), and it is characterized in that: described parent tube (3) is a steel pipe, and its inwall is compounded with anticorrosive coat, and its outer wall is compounded with polyurethane insulation coating (2) and glass fibre reinforced plastics protective layer (1) successively.
