Abstract
Provided is a steel belt strengthening poly ethylene (PE) helical bellow. The steel belt strengthening PE helical bellow comprises a helical hollow pipe body which comprises a high-density poly ethylene surface layer, a helical protrusion, a high-intensity poly ethylene middle layer and an inner pipe wall which is rolled in a spiral mode by a high-intensity poly ethylene plate and strip. The helical protrusion comprises the high-intensity poly ethylene surface layer, a polyester filament yarn weaving layer, a U-shaped steel belt layer and the high-intensity poly ethylene middle layer from outside to inside in sequence. The high-intensity poly ethylene surface layer, the polyester filament yarn weaving layer, and the U-shaped steel belt layer are in a protrusion-shaped structure. A metal net layer is arranged between the high-intensity poly ethylene middle layer and the inner pipe wall which is rolled in the spiral mode by the high-intensity poly ethylene plate and strip. The steel belt strengthening PE helical bellow has the advantages of being sound and dependable in structure, the integral rigidity is significantly improved, so that the pipe has better resistance to pressure, shock resistance fusibility, and better geological adaptability.
Description
Technical field
The utility model relates to the conveyance conduit technical field, is specially a kind of steel strip reinforced PE helical bellows.
Background technique
In the prior art, steel strip reinforced PE helical bellows inner wall smooth, the critical external compressive resistance ability is strong, can have the telescopic adjustment function destruction that eliminates stress, the advantage such as corrosion-resistant.Generally steel band mesosphere and the helical corrugation shaped polyethylene skin by polyethylene inner layer, spiral setting consists of.
Steel strip reinforced PE helical bellows is widely used in water supply, draining, blowdown, exhaust, subway ventilation, mine ventilation, field irrigation etc.The cement pipe that at present a lot of pipelines all use, steel pipe etc., these substantially all are level and smooth straight shape pipes.Can not be crooked, but also can not be incubated, such as caliduct, steam line in use, owing to not being incubated, heat loss brings certain impact, and economic benefit is not high.
