Abstract
The utility model relates to a super high anticorrosive heat preservation jacket tube. The tube wall structure in turn from interior to exterior is a metal layer, a polyurethane coating, a polyurethane foam layer and a polyethylene jacket layer. The utility model can prevent outer corrosion effectively and has characteristics of good heat insulation effect, long life-span and convenient process; the utility model can be applied to oil, chemical and other industries.
Description
Technical field
The utility model relates to transportation, the storage pipeline of the corrosion-resistanting insulation pipe of a kind of liquid transport, storage, particularly oil, industrial chemicals etc.
Background technique
At the lower northern area of temperature; the pipeline that uses in particularly remote transportation such as oil, industrial chemicals of the pipeline that uses in liquid transport, the storage, the storage must have insulation, corrosion resistant function; at present; Chang Yong pipe wall generally comprises three layers aborning; be followed successively by metal layer, polyurethane foam layer and polyethylene clipping layer; the main effect of polyurethane foam layer is insulation, and the main effect of polyethylene clipping layer is waterproof, anticorrosion and protection polyurethane foam layer.But in production and processing and using process, the polyethylene clipping layer often has crackle, hole, and the polyethylene clipping layer is not corrosion-resistant yet, therefore often causes causing the leakage of liquid in pipe owing to infiltration clipping layer, thermal insulation layers such as corrosive water, vapour cause metal layer to be corroded.With China's Daqing Area is example, is had to just change pipeline in 30 years one time owing to the jacket tube of oil transportation corrodes outward, causes significant wastage.At present the outer corrosion of jacket tube still there is not good solution.
Summary of the invention
The purpose of this utility model provides a kind of jacket tube that prevents that outer corrosive effect is good, pipeline is long service time, easy to process.
The purpose of this utility model is achieved in that a kind of superelevation corrosion-resistant thermal insulation jacket tube, tube wall comprises metal layer 1, polyurethane foam layer 3, the polyethylene clipping layer 4 that is arranged in order from inside to outside, also has polyurethane paint layer 2 between metal layer and polyurethane foam layer.The thickness of polyurethane paint layer is 1mm, and the thickness of polyurethane foam layer is 30～50mm, and the thickness of polyethylene clipping layer is 3～4mm.
The utlity model has following advantage:
1. prevent that outer corrosive effect is good, pipeline is long service time.As everyone knows, polyurethane paint has very strong antiacid, caustic corrosion effect, is sprayed on the metallic conduit outside, can prevent effectively that metallic conduit from being corroded by the external world, greatly prolonged the life-span of metallic conduit.
2. high insulating effect.Because polyurethane paint layer good airproof performance, it has prevented metal layer and extraneous heat exchange effectively with polyurethane foam layer, polyethylene clipping layer, has improved heat insulation effect.
3. easy to process.In the jacket tube processing and making process, do not need special complicated step, as long as outside metallic conduit, spray one deck polyurethane paint, after the welding of pipe joint place, can directly spray polyurethane paint, common material and method are still used in the making of polyurethane foam layer and polyethylene clipping layer, so preparation process is also uncomplicated, processes more convenient.
Description of drawings
Fig. 1 is the utility model superelevation corrosion-resistant thermal insulation jacket tube structural representation.
Embodiment
Embodiment 1
Further specify structural feature of the present utility model below in conjunction with accompanying drawing.
By shown in Figure 1, the tube wall of the utility model jacket tube is made of metal layer 1, polyurethane paint layer 2, polyurethane foam layer 3, polyethylene clipping layer 4 from inside to outside successively.Polyurethane paint bed thickness 1mm wherein, polyurethane foam bed thickness 40mm, polyethylene clipping layer thickness is 4mm.
Wherein metal layer can be stainless steel lining, iron layer, aluminium lamination etc.
