Abstract
The utility model relates to a composite antisepticising insulating tube of glass fibre reinforced plastic foam jacket which is used in the gathering and transportation of the oil, gas or other media, comprising a glass tube 1, a foam insulating layer 2 of polyurethane and an antisepticising protection layer 3 of polyethylene jacket. The composite antisepticising insulating tube mainly made of steel wires has the advantages of good erosion resistance, good insulating effect, light materials, convenient construction and erection and long service life, thus starting a new field for the tubes transporting oil, gas and other media.
Description
Technical field:
The utility model relates to a kind of defeated corrosion-resistanting insulation pipe goods of oil, rock gas and other media sets that are used for.
Background technique:
Along with the continuity and the production-scale expansion of oil-gas field development process, increase day by day for the pipeline goods demand of oil, gas gathering and transportation.At present, the defeated pipeline of on-the-spot oil gas and other media sets adopts steel master material as anti-corrosion heat insulation pipe mostly, adopts the beyond example still of other main material or preformed foam jacket composite pipe.Because the steel tube rotproofness is relatively poor, although thereby adopted multiple anti-corrosion material and technological measure, still be difficult to fundamentally overcome shortcomings such as it is perishable, working life is short, cause cost of production to improve, economic benefit is affected.
Summary of the invention:
The purpose of this utility model is to provide that a kind of corrosion resistance is strong, long service life, glass fiber reinforced plastic foam jacket composite corrosionproof thermal insulating pipeline that cost of production is low.
The utility model is to realize like this.This kind thermal insulation pipe is made up of Glass Steel Tube, polyurethane foam insulation layer and polyethylene jacket corrosion protective covering, that is is main material with Glass Steel Tube, and the polyurethane foam insulation layer is set outside it, and outermost coats layer of polyethylene jacket corrosion protective covering.This thermal insulation pipe is on conventional polyurethane foam jacket one-step method production process basis, handle by and sizing sealed at both ends Glass Steel Tube, and in foaming process, carry out the external diameter sizing, and utilize the speed-adjustable motor to drive the foaming of ratio dispensing pump, finally finish its production process.
The utility model corrosion resistance is strong, and high insulating effect has advantages such as material is light, cost is low, construction and installation are easy, long service life.Applying of this kind thermal insulation pipe is new breakthrough on pipeline corrosion protection, the heat preservation technology, for line transportation oil, gas and other media have opened frontier out-of-the-way.
Description of drawings:
Accompanying drawing is a cross-sectional view of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure; the utility model is made up of Glass Steel Tube 1, polyurethane foam insulation layer 2 and polyethylene jacket corrosion protective covering 3; its structural relation is as follows: Glass Steel Tube 1 outer surface is provided with polyurethane foam insulation layer 2, and polyurethane foam insulation layer 2 outside are coated with polyethylene jacket corrosion protective covering 3.Wherein, Glass Steel Tube 1 diameter can be the various different sizes of Φ 48-529mm; polyurethane foam insulation layer 2 and polyethylene jacket corrosion protective covering 3 adopt conventional polyurethane foam one-process preparation process and polyethylene jacket one-process preparation process to make and be coated on Glass Steel Tube 1 outer surface respectively; thermal insulation layer 2 thickness are selected by the construction requirement of design; can be 40-60mm; protective layer 3 thickness are determined by designing requirement and insulation layer thickness, are generally 3-5mm.
