Description
Technical field
The present invention relates to anti-corrosion pipe technical field, especially a kind of polyethylene compound pipe.
Background technology
High density polyethylene (HDPE) overcoat anticorrosion structure：It is made in outer surface of steel tube parcel high-density polyethylene material, there is pole
High mechanical strength and excellent decay resistance, steel pipe can be protected to be avoided during transportation, installation and use because of the external world
Factor and caused by destruction, in order to prevent steel pipe internal-surface from easily corroding, also can steel pipe internal-surface set one layer of anti-corrosion material,
But there are the following problems for setting anti-corrosion material inside and outside steel pipe：First, the adhesive force between anti-corrosion material and steel pipe is with use
The increase of time, is gradually reduced, it is easy to coming off for anti-corrosion material occurs；Secondly when aging occurs in anti-corrosion material or comes off
When, it is big to change difficulty, and it is extremely complex, it is necessary to proprietary equipment is removed to the anti-corrosion material of aging then right to change anticorrosive coat
Steel pipe carries out new anti-corrosion, and user is difficult self-changeable, is carried out to ensure antiseptic effect, it is necessary to return factory, this
Sample will greatly increase use cost, waste many times.
The content of the invention
The technical problem to be solved in the present invention is：Easily occur coming off with steel pipe to solve existing anti-corrosion material, and more
The problem of difficulty is big is changed, the invention provides a kind of polyethylene compound pipe, by setting respectively in the interior outside of metal inner pipe
Two grooves and the first groove, the second raised line are fixedly connected with the second matching grooves, and the first raised line and the first matching grooves are fixed and connected
Connect, be effectively prevented coming off for anti-corrosion material, and when aging occurs in anti-corrosion material, it is only necessary to by the anti-corrosion material of aging
Carry out changing new anti-corrosion material after extraction, it is convenient to change, and user oneself can be carried out, and greatly save cost.
The technical solution adopted for the present invention to solve the technical problems is：A kind of polyethylene compound pipe, including
Metal inner pipe, the outer surface of the metal inner pipe are provided with several first grooves, on the inner surface of the metal inner pipe
Provided with several the second grooves；
The vinyl tube matched with the outer surface of metal inner pipe, the inner surface of the vinyl tube are convex provided with first
Bar；With
The earthenware matched with the inner surface of metal inner pipe, the outer surface of the earthenware are provided with the second raised line；
The metal inner pipe is enclosed on earthenware and is fixedly connected by the second raised line with the second matching grooves, the polyethylene modeling
Expects pipe is enclosed on the metal inner pipe and is fixedly connected by the first raised line with the first matching grooves.
In order to ensure that vinyl tube and earthenware are easy for installation, the first groove and the second groove are axial along metal inner pipe
Set；In order to prevent that metal inner pipe is too thin, the line of the first groove and the second groove is not on the same Radius of metal inner pipe.
In order to ensure that vinyl tube and earthenware and metal inner pipe are fixed, first groove and the second groove
For T fonts.
Specifically, the depth of section of first groove and the second groove is 15m-20mm.
In order to be further ensured that vinyl tube and earthenware and metal inner pipe are fixed, the first groove and second recessed
Anti-slip rubber layer is provided with groove.
Specifically, the anti-slip rubber layer is 3mm-5mm.
The beneficial effects of the invention are as follows：The invention provides a kind of polyethylene compound pipe, is effectively prevented polyethylene modeling
Coming off for expects pipe and earthenware, ensure that vinyl tube and earthenware and metal inner pipe are fixed, and polyethylene is moulded
When there is aging in expects pipe or earthenware, it is only necessary to changed, changed after extracting the vinyl tube of aging or earthenware out
It is convenient, replacing construction is greatly reduced, reduces use cost.
Brief description of the drawings
