Abstract
The utility model discloses an inner lining and exterior coating steel-plastic composite pipe, which comprises a steel pipe main body. An inner lining layer made of polyethylene material is adhered on the inner surface of the steel pipe main body; an exterior coating layer made of epoxy resin is coated on the exterior surface of the steel pipe. The utility model has the advantages of good anticorrosion performance, great improvement of the whole service life of pipe products, 5 to 10 times of the service life of a galvanized pipe, low production cost and good application and generalization value. The utility model can be widely used in doors and outdoors and can be buried under the ground.
Description
Technical field
The utility model relates to a kind of tubing, relates to a kind of liner specifically and is coated with steel-plastic composite pipe outward.
Background technique
Domestic water supply of the prior art, steam line mostly are Coating Steel Pipe, and this class pipeline was often using several years or will scrap the pipeline of having to more renew because of the corrosion problem in shorter time.Particularly for the replacing of buried pipe, not only can cause the waste of human and material resources, even also can cause in various degree loss to building, the PP one R tubing that the usefulness that also has is common, though the hot melt feature is arranged, benefit from long service life, be difficult for corrosion, but it exist intensity low, leak and shortcoming such as damage very easily easily.
Occurred multiple steel-plastic composite pipe in the market, its structure generally is that inside and outside layer is extruded extrusion molding, and the mesosphere is steel tubing (mesh is arranged or do not have mesh).For there being the mesh steel to mould pipe,, must increase wall thickness in order to satisfy bearing requirements, the pipe flow area is reduced, materials consumption is risen, the cost height, and do not have the mesh steel mould pipe in mould and bondingly between layer and the steel pipe also have some because technologic problem can cause the phenomenon that the part can not strong bond.
Summary of the invention
Problem to be solved in the utility model provides a kind of liner and is coated with steel-plastic composite pipe outward, can improve stainless property, increases the service life, and reduces production costs.
For addressing the above problem, the utility model by the following technical solutions:
A kind of liner is coated with steel-plastic composite pipe outward, comprises the steel pipe body, it is characterized in that: the internal surface of described steel pipe body is stained with the inside liner made from polythene material, the external coating that the coated useful epoxy resin of the outer surface of described steel pipe is made.
Below be the utility model for further improvement of these options:
Having the adhesive layer that hot melt adhesive is made between the inwall of described inside liner and steel pipe body, is one with the stickup of inside liner and steel pipe body, makes it more firm and corrosion-resistant.
Beneficial effect
Pipeline outer-layer of the present utility model adopts anticorrosion modified epoxy powder, behind high temperature preheating, epoxy powder and outer wall of steel pipe are through high temperature welding and iron and steel be combined into, coating surface is smooth, attractive in appearance, antiseptic property is good, can be widely used in indoor and outdoor and bury ground, inside liner is the good polythene material of chemical stability, smooth homogeneous (uniform) fluid resistance is little, shock-resistant, non-scaling, do not peel off, do not come off, thereby do not block the whole service life that pipeline has improved pipe-line system greatly, the utility model had both had the high pressure resistant of steel pipe, characteristics such as easy connection, have the corrosion-resistant of plastic tube again, advantages such as health, the utility model has improved the whole service life of tubing greatly, be 5～10 times of galvanized pipe working life, and cost of production is lower, has good use value and promotional value.
Below in conjunction with drawings and Examples the utility model is described further:
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
Embodiment, as shown in the figure, a kind of liner is coated with steel-plastic composite pipe outward, comprise steel pipe body 2, the internal surface of described steel pipe body 2 is stained with the inside liner made from polythene material 3, because the chemical stability of polythene material is good, therefore the smooth surface homogeneous (uniform) fluid resistance of the inside liner made from polythene material is little, shock-resistant, non-scaling, do not peel off, do not come off, thereby do not block the whole service life that pipeline has improved pipe-line system greatly, has the adhesive layer 1 that hot melt adhesive is made between the inwall of described inside liner 3 and steel pipe body 2, with the stickup of inside liner and steel pipe body is one, make it more firm and corrosion-resistant, the outer surface of described steel pipe 2 is coated with anticorrosion modified epoxy powder, behind high temperature preheating, epoxy powder combines with iron and steel through the high temperature welding with outer wall of steel pipe and forms external coating 4, the external coating smooth surface, attractive in appearance, antiseptic property is good, can be widely used in indoor and outdoor and bury ground, the utility model had both had the high pressure resistant of steel pipe, characteristics such as easy connection, have the corrosion-resistant of plastic tube again, advantages such as health, the utility model has improved the whole service life of tubing greatly, be 5～10 times of galvanized pipe working life, and cost of production is lower, has good use value and promotional value.
