Description

A kind of polyethylene compound pipe

Technical field

Anti-corrosion pipe technical field is the utility model is related to, 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 corrosion resistance, can protect steel pipe to be avoided during transportation, installation and use because of the external world Factor and caused by destruction, steel pipe internal-surface easily corrodes in order to prevent, 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 replace difficulty, and it is extremely complex, it is necessary to proprietary equipment is removed the anti-corrosion material of aging then right to replace erosion resistant coating Steel pipe carries out new anti-corrosion, and user is difficult self-changeable, is carried out to ensure anti-corrosion effect, it is necessary to return factory, this Sample will greatly increase use cost, waste many times.

Utility model content

The technical problems to be solved in the utility model is：Easily occur coming off with steel pipe to solve existing anti-corrosion material, And the problem of difficulty is big is replaced, the utility model provides a kind of polyethylene compound pipe, passes through the interior outside point in metal inner pipe Second groove and the first groove are not set, and the second raised line is fixedly connected with the second matching grooves, the first raised line and the first groove With being fixedly connected, coming off for anti-corrosion material is effectively prevented, and when aging occurs in anti-corrosion material, it is only necessary to by aging Carry out replacing new anti-corrosion material after anti-corrosion material extraction, it is convenient to replace, and user oneself can carry out, and greatly save Cost.

Technical solution is used by the utility model solves its technical problem：A kind of polyethylene compound pipe, including

Metal inner pipe, the outer surface of the metal inner pipe are equipped with several first grooves, the interior table of the metal inner pipe Face is equipped with several second grooves；

With the matched vinyl tube in outer surface of metal inner pipe, the inner surface of the vinyl tube is equipped with first Raised line；With

With the matched ceramic tube of inner surface of metal inner pipe, the outer surface of the ceramic tube is equipped with the second raised line；

The metal inner pipe is sleeved on ceramic tube and is fixedly connected by the second raised line with the second matching grooves, the poly- second Alkene plastics pipe sleeve is fixedly connected on the metal inner pipe and by the first raised line with the first matching grooves.

In order to ensure that vinyl tube and ceramic tube are easy for installation, the first groove and the second groove are axial along metal inner pipe Set；Metal inner pipe is too thin in order to prevent, and 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 ceramic tube 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 further ensure vinyl tube and ceramic tube and metal inner pipe are fixed, the first groove and second recessed Anti-slip rubber layer is equipped with groove.

Specifically, the anti-slip rubber layer is 3mm-5mm.

The beneficial effects of the utility model are：The utility model provides a kind of polyethylene compound pipe, effectively prevents Coming off for vinyl tube and ceramic tube, ensure that vinyl tube and ceramic tube and metal inner pipe are fixed, and When there is aging in vinyl tube or ceramic tube, it is only necessary to will be carried out more after the vinyl tube of aging or ceramic tube extraction Change, it is convenient to replace, and greatly reduces replacing construction, reduces use cost.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is a kind of structure diagram of polyethylene compound pipe of the utility model；
