Abstract
The utility model relates to a transport pipeline. The anti-corrosion of the pipeline is improved. The structure is characterized in that a glass steel pipe firmly adhered to a steel pipe in a whole is copied on the outer wall of the metal steel pipe. The utility model has the advantages of corrosion resistance and long service life.
Description
The utility model relates to a kind of conveyance conduit, mainly be that the anticorrosion of heating agent conveyance conduit done to improve at present, great majority adopt the metal steel pipe in the use of conveyance conduit, but after long-term the use, metal is perishable, cause leakage, not only loss the energy but also polluted environment, it is unfavorable to have brought to maintenance work.
At known patent announcement is to disclose a kind of glass fibre reinforced plastics casing insulation direct buried pipe among the GN88201715.2, it is to be made of metal steel pipe, separation layer, thermal insulation layer, glass fibre reinforced plastics casing, though, played certain antisepsis to having multi-layer resinous thin foam separation layer on the outer wall of metal steel pipe.(the thin foam compressive strength of resin is 2-3kg/cm
2), but because pipeline is buried in underground, the long-term use of metal steel pipe warp can produce local etching or break, and cause leakage, cause liquid or gas excessive,, and destroy separation layer, cause thermal insulation property bad because of the pressure of liquid in the pipeline or gas compressive strength much larger than separation layer, also need dig out and more renew pipeline, bring very big difficulty to maintenance work.
The purpose of this utility model provides a kind of mechanical property that is similar to metal, has corrosion-resistant, the steel of pressure resistance, composite glass steel pipe.
The purpose of this utility model can reach by following measure: a kind of steel, glass composite pipe are to be made of metal steel pipe (1), thermal insulation layer (3), shell (4), it is characterized in that: be included in duplicate on the outer wall of metal steel pipe one with metal steel pipe good bond be the Glass Steel Tube of one.
Accompanying drawings:
Fig. 1 is a structural drawing of the present utility model.
The utility model will be further described in conjunction with example:
See accompanying drawing 1.Directly be wound in Glass Steel Tube (2) with glass fibre zero twisted yarn impregnation on the outer wall of metal steel pipe (1), making it metal steel pipe (1) is one with Glass Steel Tube (2) good bond, forms steel, glass composite pipe.
The utility model has compared to existing technology can reduce cost 50%, and life-saving 2-3 doubly.
Claims (2)
1, a kind of steel, composite glass steel pipe are to be made of metal steel pipe (1), thermal insulation layer (3), shell (4), it is characterized in that: it also is included in the Glass Steel Tube (2) that the firm cementation of metal steel pipe (1) is bonded as one.
2, by the described steel of claim 1, composite glass steel pipe, it is characterized in that: Glass Steel Tube (2) is to be entwined with the direct impregnation of glass fibre zero twisted yarn.
