Abstract
The invention discloses a kind of steel lining composite pipe structure.The both ends of steel-tube construction layer and steel-tube construction layer that it includes outer layer are welded with adpting flange, have the corrosion-inhibiting coating of steel-tube construction layer and adpting flange integral coating outside steel-tube construction layer and adpting flange, there is the plastic layer for directly coating steel-tube construction layer and adpting flange, going back compound coating in plastic layer has polyolefin undercoating in steel-tube construction layer and adpting flange.After above-mentioned structure; so that whole body can be effectively protected; particularly the junction of steel-tube construction layer and adpting flange is provided with the concaveconvex structure of arc and causes junction gap small and caused that connection combined strength bination is high after compound; in addition; the waves structure that clad is set; the difference of the compactness of connection and relief fabric size is improved so that being completely embedded property is higher; make destruction and corrosion of the inner layer composite material layer not by malleation; avoid and come off out of steel pipe, extend service life.
Description
Technical field
The present invention relates to a kind of line pipe material, specifically a kind of steel lining composite pipe structure.
Background technology
Steel lining multiple tube is combined by plastic tube and steel pipe, wherein, flanged (FLGD) steel pipe is outer as reinforcement sheath
Layer, internal layer of the plastic tube as matrix tubing, the matrix tubing of internal layer along the outer layer mouth of pipe extend to end face of flange outer rim formed it is whole
The pipe-line equipment of body, it is corrosive liquid mainly for delivery of concentrated nitric acid and chloroazotic acid yet with the pipeline, existing multiple tube
Although certain corrosion resistance can be reached, at the flanged ends of tubing, due to needing to enter into being about to adjacent body
Row connects, and has gap between its junction, hence in so that fluid easily damages to its gap location, so that matrix tubing
Start to come off out of steel pipe in junction, have impact on service life.
The content of the invention
The technical problem to be solved in the present invention, which provides one kind, can improve junction adhesion, so as to ensureing that body is prolonged resistance to
Steel lining composite pipe structure.
In order to solve the above-mentioned technical problem, steel lining composite pipe structure of the invention, including the steel-tube construction layer of outer layer and
The both ends of steel-tube construction layer are welded with adpting flange, have outside steel-tube construction layer and adpting flange by steel-tube construction layer and company
Have in the corrosion-inhibiting coating of acting flange integral coating, steel-tube construction layer and adpting flange steel-tube construction layer and adpting flange is direct
The plastic layer of cladding, going back compound coating in plastic layer has polyolefin undercoating.
The junction of the steel-tube construction layer and adpting flange is provided with arcuate relief structure.
The joint face of the adpting flange is arranged to wavelike structure, and the plastic layer is combined with the joint face of adpting flange
Place is similarly wavelike structure, and the wavy relief fabric of the plastic layer is less than the wavy knot that rises and falls of joint face of adpting flange
Structure.
Wavelike structure, the polyene are similarly at the wavelike structure faying face of the polyolefin undercoating and plastic layer
The internally coated wavy relief fabric of hydrocarbon is less than the wavy relief fabric of plastic layer.
After above-mentioned structure, have steel-tube construction layer due to the surfaces externally and internally of steel-tube construction layer and adpting flange and
Corrosion-inhibiting coating, plastic layer and the polyolefin undercoating of adpting flange integral coating, so that whole body can access
The concaveconvex structure that effectively protection, the particularly junction of steel-tube construction layer and adpting flange are provided with arc causes junction gap
It is small and caused that connection combined strength bination is high after compound, in addition, the waves structure that clad is set, improves connection
The difference of compactness and relief fabric size make it that being completely embedded property is higher, inner layer composite material layer is not destroyed by malleation
And corrosion, avoid and come off out of steel pipe, extend service life.
Brief description of the drawings
Fig. 1 is the partial structural diagram of steel lining composite pipe structure of the present invention.
Embodiment
With reference to the accompanying drawings and detailed description, the steel lining composite pipe structure of the present invention is described in further detail.
As illustrated, the steel lining composite pipe structure of the present invention, includes the steel-tube construction layer 1 and steel-tube construction layer 1 of outer layer
Both ends be welded with adpting flange 2, the junction of steel-tube construction layer 1 and adpting flange 2 is provided with the concaveconvex structure of arc,
The uniformity of connection can be improved after adjacent multiple tube connection by the concaveconvex structure design of arc, avoids conventional orthogonal
The water caltrop that connected mode has, so as to reduce destructiveness, have outside steel-tube construction layer 1 and adpting flange 2 by steel-tube construction layer 1
Have steel-tube construction layer 1 with the corrosion-inhibiting coating 3 of the integral coating of adpting flange 2, in steel-tube construction layer 1 and adpting flange 2 and connect
The plastic layer 4 that acting flange 2 directly coats, going back compound coating in plastic layer 4 has polyolefin undercoating 5.
Further, the joint face of described adpting flange 2 is arranged to wavelike structure, the plastic layer 4 and connection method
The joint face junction of orchid 2 is similarly wavelike structure, and the wavy relief fabric of the plastic layer 4 is less than adpting flange 2
The wavy relief fabric of joint face, polyolefin undercoating 5 at the wavelike structure faying face of plastic layer 4 with being similarly wavy knot
Structure, the wavy relief fabric of polyolefin undercoating 5 are less than the wavy relief fabric of plastic layer 4.
