Description
Technical field
The utility model is related to a kind of multiple tubes, more particularly to a kind of EXPE steel multiple tube.
Background technology：
In existing anticorrosion process, oil gas water pipeline using glass flake and other paint class materials in pipeline prevent
Corruption uses mechanical trolley just internal joint patch, long construction period, complex process, and paints what class material volatilized after the completion of welding
Organic solvent can cause environmental pollution.Paint class material peel strength is low, and impact strength is small, is constructing and using process
In, it be easy to cause the damage of paint and falls off, lose antisepsis.Above-mentioned technique can not complete small pipe-line（Below diameter 89）
Interior anti-corrosion, therefore small pipe-line seriously corroded in use, perforation is frequent, and it is higher frequently to replace pipeline construction cost.
Utility model content：
In view of the above-mentioned problems of the prior art, to provide a kind of EXPE steel of reasonable design compound for the utility model
Pipe, technical solution are：
A kind of EXPE steel multiple tube, including multiple seamless steel pipe matrixes, the seamless steel pipe matrix are coated with erosion resistant coating,
Seamless steel pipe matrix joint mirror symmetry is welded with isometrical special joint, and the special joint is equipped with gasket groove, gasket groove
Interior to be equipped with seal washer, special joint outer layer is fixedly connected with clamp special, and clip outer layer is coated with erosion resistant coating；The seamless steel
Pipe matrix and special joint internal layer are closely fitted with EXPE ultra-high molecular weight polyethylene bushing pipes.
Above-mentioned technical proposal can be further improved for：
The erosion resistant coating outer layer is also covered with insulating layer.
The seamless steel pipe matrix is elbow matrix.
By the technical program, perfectly solve small pipe-line cannot in anti-defective workmanship, EXPE supra polymers
Amount internal lining pipe has many advantages, such as anti-corrosion, wear-resisting, shock resistance, self-lubricating, improves the transfer efficiency of medium.Inside and outside anticorrosive coating directly every
The contact of medium and steel pipeline absolutely, greatly improves service life.Work progress is environmentally friendly, pollution-free.Connection type letter
It is single easy to operate, reduce labor intensity.
Description of the drawings：
Fig. 1 is 1 structural schematic diagram of the utility model embodiment；
Fig. 2 is 2 structural schematic diagram of the utility model embodiment；
Wherein：1, polyurethane insulation coating, 2, clamp special, 3, special joint, 4, seamless steel pipe matrix, 5, EXPE superelevation point

Specific implementation mode：
Embodiment 1：
As shown in Figure 1, a kind of EXPE steel multiple tube, including multiple seamless steel pipe matrixes 4, the seamless steel pipe matrix 4
Coated with PE erosion resistant coatings 7,7 outer layer of PE erosion resistant coatings is covered with polyurethane insulation coating 1, the 4 joint mirror symmetry weldering of seamless steel pipe matrix
It is connected to isometrical special joint 3, the special joint 3 is equipped with gasket groove, is equipped with seal washer 6 in gasket groove, outside special joint 3
Layer is fixedly connected with clamp special 2, and 2 outer layer of clamp special is coated with PE erosion resistant coatings；The seamless steel pipe matrix 4 and special joint
3 internal layers are closely fitted with EXPE ultra-high molecular weight polyethylenes bushing pipe 5.
Embodiment 2：
As shown in Fig. 2, a kind of EXPE steel multiple tube, including multiple seamless steel pipe matrixes 4 and elbow matrix 8, seamless steel
Pipe matrix 4 is welded with isometrical special joint 3 with 8 joint mirror symmetry of elbow matrix, and the special joint 3 is equipped with washer
Slot, gasket groove is interior to be equipped with seal washer 6, and 3 outer layer of special joint is fixedly connected with clamp special 2；The seamless steel pipe matrix 4,
Elbow matrix 8 and 3 internal layer of special joint are closely fitted with EXPE ultra-high molecular weight polyethylenes bushing pipe 5.
Making the technological process of EXPE steel multiple tubes is：Seamless steel pipe matrix 4 is first subjected to 7 PE anti-corrosions and polyurethane
Insulating layer 1 is prefabricated, and specific embodiment presses Party A's design requirement, executes standard and presses SY/T0420-1997 practical operations, by seal washer
6 are placed in the gasket groove of special joint 3, then 3 special joints are welded at 4 both ends of seamless steel pipe matrix, by EXPE supra polymers
Weight northylen bushing pipe 5 carries out isometrical compression, wears and is lining in 3 inner wall of steel pipe matrix 4 and special joint, waits EXPE superhigh molecular weight polyethylenes
Alkene bushing pipe 5 is expanded to combine closely with steel pipe matrix 4 and special joint 3 after, complete EXPE ultra-high molecular weight polyethylenes bushing pipe 5
The operations such as flange execute standard and press Q/SH1020 1889-2017《Liner oil pipe general technical specifications》Practical operation uses personality card
2 connection special joint 3 of hoop, finally completes the outer anti-corrosion of clamp special 2 and junction, keeps the inside and outside formation of steel pipe matrix continuous anti-
Rotten layer.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with the power
Subject to the protection domain that profit requires.
