Abstract
The invention discloses a kind of steel lining polyfluortetraethylecomposite 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, the joint face of adpting flange is provided with annular groove, the joint face of steel-tube construction layer and adpting flange has the plastic layer for directly coating steel-tube construction layer and adpting flange, compound coating is gone back in plastic layer polyolefin undercoating, and plastic layer and polyolefin undercoating are compounded in annular groove.After said structure; etch-proof protective effect can be played by compound plastic layer and polyolefin undercoating after the connection of 2-section pipe road and the composite bed improves sealing being used as etch-proof function while being also used as sealing structure; so that the compactness of pipeline connection is very high; 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 polyfluortetraethylecomposite 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 polyfluortetraethylecomposite composite pipe of the invention, the steel-tube construction of outer layer is included
The both ends of layer and steel-tube construction layer are welded with adpting flange, have outside steel-tube construction layer and adpting flange by steel-tube construction
The corrosion-inhibiting coating of layer and adpting flange integral coating, the joint face of adpting flange are provided with annular groove, steel-tube construction layer and company
The joint face of acting flange has the plastic layer for directly coating steel-tube construction layer and adpting flange, and going back compound coating in plastic layer has
Polyolefin undercoating, plastic layer and polyolefin undercoating are compounded in annular groove.
The connection end of the steel-tube construction layer and adpting flange is provided with arc angling.
Plastic layer and the polyolefin undercoating is compounded in annular groove processus aboralis for the inner chamber of annular groove.
After above-mentioned structure, because the joint face of adpting flange is provided with annular groove, in plastic layer and polyolefin
Coating is compounded in annular groove and plastic layer and polyolefin undercoating are compounded in annular groove processus aboralis for annular groove
Inner chamber, thus 2-section pipe road connection after etch-proof protection can be played by compound plastic layer and polyolefin undercoating
Act on and the composite bed is being also used as sealing structure to improve sealing simultaneously as etch-proof function so that pipeline
The compactness of connection is very high, makes destruction and corrosion of the inner layer composite material layer not by malleation, avoids and come off out of steel pipe, prolonged
Service life is grown.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of steel lining polyfluortetraethylecomposite composite pipe structure of the present invention；
Fig. 2 is Fig. 1 A-A cross section structure diagrams.
Embodiment
With reference to the accompanying drawings and detailed description, the steel lining polyfluortetraethylecomposite composite pipe structure of the present invention is made further
Describe in detail.
As illustrated, the steel lining polyfluortetraethylecomposite composite pipe structure of the present invention, includes the steel-tube construction layer 1 and steel of outer layer
The both ends of tubular construction layer 1 are welded with adpting flange 2, have outside steel-tube construction layer 1 and adpting flange 2 by steel-tube construction layer 1
With the corrosion-inhibiting coating 3 of the integral coating of adpting flange 2, the joint face of adpting flange 2 is provided with annular groove, the He of steel-tube construction layer 1
The joint face of adpting flange 2 has the plastic layer 4 that directly coats steel-tube construction layer 1 and adpting flange 2, also multiple in plastic layer 4
Conjunction is coated with polyolefin undercoating 5, and plastic layer 4 and polyolefin undercoating 5 are compounded in annular groove.
Further, the connection end of described steel-tube construction layer 1 and adpting flange 2 is provided with arc angling 6, from there through
Arc-shaped transition reduces the degree of wear, and plastic layer 4 and polyolefin undercoating 5 are compounded in annular groove processus aboralis for annular groove
Inner chamber, good sealing property served by certain elastic deformation after the connection of two segment pipes.
