Type, is the plastic pipe being developed and applied earliest, as plumbing, protecting pipe etc..Existing pvc pipe is generally simple list
Rotating fields, therefore impact resistance ability, bearing capacity and oxygen resistance are poor, and exist that linear expansion coefficient is high, use the longevity
Order low shortcoming.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of steel strip reinforced pvc pipe, this practicality
It is new be not only simple in structure, synthesis rationality easy to use and pvc pipe it is stronger.
To achieve the above object, the utility model proposes a kind of steel strip reinforced pvc pipe, including interior pvc pipe layer, the first heat
Melt layer, steel belt layer, the second hot melt adhesive layer and outer pvc pipe layer, first hot melt adhesive layer are distributed in interior pvc pipe layer and steel belt layer
Between, second hot melt adhesive layer distribution between outer pvc pipe layer and steel belt layer, the steel belt layer by the first hot melt adhesive layer and
Second hot melt adhesive layer is clipped between interior pvc pipe layer and outer pvc pipe layer, and described steel belt layer is the steel pipe knot being welded by steel band
Structure, when a kind of steel strip reinforced pvc pipe is cold water pipe, the interior pvc pipe layer and outer pvc pipe layer use PVC-U pipes；When one
When planting steel strip reinforced pvc pipe for hot-water line, the interior pvc pipe layer and outer pvc pipe layer use PVC-C and manage.
The beneficial effects of the utility model：The utility model is used by increased steel belt layer on traditional pvc pipe
The special technological process of production is produced and processed, and so as to obtain, a kind of excellent shock resistance, bearing capacity are strong, hinder oxygen
Excellent performance, low linear expansion coefficient, the compound pipeline complex pipeline of long service life so that PVC pipeline can build in municipal water supply, high level
Feedwater, oil, chemical industry, building, shipbuilding, communication, electric power and underground gas transmission field is built to use.
