Description
Technical field
This utility model relates to steel-plastics composite pipe technical field, particularly relates to the steel of a kind of novel box-like structure of interior Jinsuo
Plastic composite.
Background technology
Along with the application of line plastic-steel tube constantly extends, people propose higher wanting to line plastic-steel tube product quality
Ask.In up-to-date steel-plastics composite pipe national standard, the steel of steel-plastics composite pipe is moulded adhesion intensity index and has been thus lifted to higher
Numerical value.But the most often there are the feelings of pipe layered delamination in the steel-plastics composite pipe of traditional structure
Condition；What is more, and pipeline occurs in that in running inner lining plastic tube entirety comes off displacement, causes pipe-line system to block, gives
The society of user brings serious economic loss.
Separately having the China Patent No. to be: 00254219.6, publication date is 2001.8.22, it is provided that a kind of improved lining plastic-steel
Pipe, it is made up of with plastic inner lining pipe steel outer tube.By the inner wall coarse of steel pipe so that it is uneven, can sting, roll
Flower, grooving etc., penetrate in the steel pipe of inner wall coarse by plastic tube, makes steel pipe compress inner lining plastic tube by extruding tube reducing, to solve
Certainly due to different material characteristics between line plastic-steel tube inner and outer pipe, the problem that the axial harmomegathus of generation is inconsistent.
The defect of above-mentioned patent: between 1, steel is moulded, essence is to separate；Rely solely on after outer steel pipe is extruded tube reducing moulding
The cladding restraining forces of material pipe makes one entirety of the moulding one-tenth of steel；2, steel is moulded interlayer and is easily entered fluid media (medium)；Between moulding because of this structural steel
Not forming adhering and sealing, after Pipe installing completes, the fluid media (medium) of conveying easily enters steel and moulds interlayer, thus corrodes outer steel
Pipe causes water pollution once again；Meanwhile, because outer steel pipe is contacted by fluid, the anticorrosion internal layer of pipeline just loses meaning, pipeline
System will quickly be destroyed, and affects the safe operation of tubing；3, said structure is to plastic material and performance requirement pole
High；Because outer steel pipe forms extrusion cladding power to plastics during tube reducing, if plastics are softer, then between steel is moulded, restraining forces is the least,
Mould Guan Yicong steel duct to come off；If plastics are harder, then plastic hoop rigidity is high, and outer steel pipe is easily caused to mould to manage during tube reducing and breaks
Split, make outer steel pipe scrap with moulding Guan Jun；4, the steel plastic compount tube steel using said structure formation is moulded adhesion intensity and is only capable of reaching
0.2-0.3Mpa, moulds the regulation requiring minimum adhesion intensity 1.0Mpa in pipe GB far below steel.
Utility model content
In order to overcome the defect of above-mentioned prior art, this utility model provides the box-like steel-plastics composite pipe of Jinsuo in one,
Its objective is to guarantee steel pipe after lining moulds process, will not because of steel mould between poor attachment cause steel to mould to be layered even steel and mould point
From phenomenon, it is ensured that pipe-line system safe operation.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
The box-like steel-plastics composite pipe of Jinsuo in a kind of, including outer steel pipe, plastic anti-corrosion layer and adhering resin layer, plastic anti-corrosion layer
It is bonded on the inwall of outer steel pipe by adhering resin layer, it is characterised in that: the inwall of described outer steel pipe is provided with a plurality of protrusion
Rib in outer steel pipe inner wall.
On the inwall of the prefabricated steel pipe outside of described rib, adhering resin layer fills up the space between each rib.
Described rib is arranged along the circumferencial direction of outer steel pipe inner wall.
Described rib is circular arc or triangle or rectangle.
Distance between adjacent rib 2 is between 20mm-40mm, and the height of rib 2 is 0.2mm-0.4mm.
This utility model has the advantage that
1, the inwall of the outer steel pipe of this utility model is provided with a plurality of rib protruding from outer steel pipe inner wall, and described rib is prefabricated
Outside on the inwall of steel pipe, adhering resin layer fills up the space between each rib.Not only make use of what steel moulded by adhering resin to have
Imitate bonding, also use the steel-tube construction physical constraint to plastics；Can further promote steel mould between adhesion intensity, fall
The risk of layering moulded by low steel, makes pipe-line system have more excellent safe operation ability.
2, this utility model rib is arranged along the circumferencial direction of outer steel pipe inner wall, and lifting steel is moulded and tied between longitudinal direction in steel pipe
Make a concerted effort intensity, rib be circular arc or triangle or its adhesion of rectangle more preferably.
3, the distance between the adjacent rib of this utility model 2 is between 20mm-40mm, and the height of rib 2 is 0.2mm-
0.4mm, it is ensured that will not be because of the constraint to endothecium structure of the rib spacing reduction rib excessive, the most too low；Also between will not be because of rib
Away from too small, excessive height affect endothecium structure bonding with outer steel pipe time interlayer residual gas spilling, be more beneficial for bonding about
Bundle, thus improve steel further and mould the adhesion intensity of interlayer, it is ensured that pipeline can effectively suppress steel to mould interlayer in running
Separation trend, stops steel and moulds layering.
