Abstract
The utility model discloses a steel pipe for vapour car skeleton, include: steel pipe body, first counter -bending resilience layer, first thermal -insulated resilience combined material layer, the counter -bending resilience of second layer and second septum thermoresilience combined material layer, the steel pipe body the internal surface from outside set gradually toward in first counter -bending resilience layer with first thermal -insulated resilience combined material layer, having set gradually outside toward from interior of surface of steel pipe body the counter -bending resilience of second layer with second septum thermoresilience combined material layer. In this way, the utility model discloses counter -bending resilience can be good, and thermal -insulated effect is good, can effectively prolong the life of car.
Description
Technical field
This utility model is related to steel pipe field, more particularly to a kind of steel pipe for automobile skeleton.
Background technology
Steel pipe is a kind of strip steel of hollow, is used as the pipeline of conveyance fluid, such as oil, natural gas, water, coal in a large number
Gas, steam etc., in addition, when doing that curved, torsional strength is identical, lighter in weight, so be also widely used in manufacture machine components and work
Journey structure.
Steel pipe can be divided into two big class by production method：Seamless steel pipe and seamed steel pipe, seamed steel pipe is referred to as steel pipes with straight.
Seamless steel pipe can be divided into by production method：Hot seamless tube, drawn tube, precision tube, hot-expanding pipe, cold spinning pipe and extruded tube
Deng.Seamless steel pipe is made with Fine Steel Casting iron or steel alloy, has hot rolling, cold rolling（Pull out）Point.Seamless steel pipe can be used for various row
The liquid air-pressure duct of industry and gas pipeline etc..Welded pipe line can be used for aqueduct, gas piping, caliduct, electrical equipment pipe
Road etc..
However, the counter-bending rebound performance currently used for the steel pipe of automobile skeleton is poor, effect of heat insulation also not good it is impossible to enough have
Effect extends the service life of automobile.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of steel pipe for automobile skeleton, counter-bending resilience
Can be good, effect of heat insulation is good, can effectively extend the service life of automobile.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is：One kind is provided to be used for automobile bone
The steel pipe of frame, including：Steel pipe body, the first counter-bending resilient layer, the first heat-insulated resilience composite material layer, the second counter-bending resilience
Layer and the second heat-insulated resilience composite material layer, the described inner surface of steel pipe body from being disposed with outward described the inside
One counter-bending resilient layer and the described first heat-insulated resilience composite material layer, the described outer surface of steel pipe body from interior outward
It is disposed with the second described counter-bending resilient layer and the described second heat-insulated resilience composite material layer.
In one preferred embodiment of this utility model, the first described counter-bending resilient layer is 0Cr21Ni6Mn9N layer.
In one preferred embodiment of this utility model, the second described counter-bending resilient layer closes for BFe10-1-1 cupro-nickel
Layer gold.
In one preferred embodiment of this utility model, the first described heat-insulated resilience composite material layer and second heat-insulated time
Elastic composite material layer is polycrystalline mullite fibre layer.
The beneficial effects of the utility model are：The counter-bending rebound performance of this utility model is good, and effect of heat insulation is good, can be effective
Extend the service life of automobile.
