Abstract
The utility model discloses a tectorial membrane protecting plastic lining metal pipe, which comprises a metal pipe body. The characteristics lie in that a non-poisonous food-grade polyethylene or polypropylene layer is arranged on the inner surface of the metal pipe body as the plastic lining and the outer surface is covered with a PVC membrane. The utility model combines the advantages of metal and plastic effectively. The plastic inside keeps the pipe material clean, fouling-free and rust-free, and meanwhile separate the metal pipe from the liquid to prevent metal pipe rust polluting the transported liquid. At the same time, the metal pipe gives high mechanical intensity to the pipe material while the PVC membrane outside the pipe effectively protects the pipe material when used and constructed.
Description
Technical field
The utility model relates to a kind of metal tube, particularly a kind of metal tube that is applicable to industry FLUID TRANSPORTATION such as water purification transporting system, building water supply system and food, medicine, wine brewing.
Background technique
FLUID TRANSPORTATION in industries such as water purification transporting system, building water supply system and food, medicine, wine brewing normally adopts line transportation.These conveyance conduits in use can occur corrosion because of oxidation, and the pipeline of corrosion can pollute carrying liquid.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of overlay film protection lining to mould metal tube, and this metal tube can prevent effectively that in use the metallic conduit of corrosion from polluting the fluid of carrying.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of overlay film protection lining is moulded metal tube, comprises the metal body, it is characterized in that having moulded nontoxic food-grade polyethylene or polypropylene layer at the inner surface lining of metal body, and the outer surface of metal body is coated with polychloroethylene film.
Described metal body is an aluminium alloy pipe, and this aluminum alloy body is a seamless tube body.
The beneficial effects of the utility model are: the utility model has been moulded nontoxic food-grade polyethylene or polypropylene layer at the inner surface lining of metal tube, thereby the advantage of metal and plastics is organically combined, the plastics of its internal layer make the clean health of tubing, non-scaling, non-corrosive, metal tube and fluid partitioning can be opened simultaneously, the fluid of carrying be polluted with the rust stain that prevents metal tube; The metal tube layer makes tubing have very high mechanical strength simultaneously, and the PVC coating film of pipe outer surface can make tubing obtain better protection in using and constructing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a schematic cross-section of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2; the disclosed a kind of overlay film protection lining of the utility model is moulded metal tube; comprise metal body 1; metal body 1 can adopt aluminium alloy pipe; and the pipeline that aluminium alloy pipe is made is seamless tube body preferably; certainly, metal body 1 also can adopt other metal material to make, and is not described further at this.Nontoxic food-grade polyethylene or polypropylene layer 2 have been moulded at the inner surface lining of metal body 1, the outer surface of metal body 1 is coated with polychloroethylene film 3, metal body and internal and external layer material are closely compound, do not add any tackiness agent, and in-20 ℃-120 ℃ temperature range, carry out ageing treatment repeatedly, make plastic cord expansion system and aluminum alloy become approaching, thereby can not cause layering to come off and stretch.
The utility model is widely used in the FLUID TRANSPORTATION of industries such as water purification transporting system, building water supply system and food, medicine, wine brewing, and the combustion gas that also can be used as gas burning system is carried.
The above only is preferred embodiment of the present utility model, can not limit protection domain of the present utility model with it, so long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
