Abstract
The invention discloses an anti-collapse steel pipe. The anti-collapse steel pipe comprises a steel pipe body, a BT-110T sleeve pipe layer, a carbon black filling rubber layer, an elastic polyolefin layer, an SEW-80TT highly anti-extrusion sleeve pipe layer and a rare earth composite elastic material layer, wherein the BT-110T sleeve pipe layer, the carbon black filling rubber layer and the elastic polyolefin layer are sequentially arranged on the outer surface of the steel pipe body from inside to outside; the SEW-80TT highly anti-extrusion sleeve pipe layer and the rare earth composite elastic material layer are sequentially arranged on the inner surface of the steel pipe body from outside to inside. In this way, the anti-collapse steel pipe is good in anti-extrusion performance and not prone to deformation in the extrusion process, and later use is not affected.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of Anti-collapse steel pipe.
Background technology
Steel pipe is the strip steel of a kind of hollow, a large amount of pipelines being used as conveyance fluid, such as oil, natural gas, water, coal gas, steam etc., it addition, when doing curved, torsional strength and being identical, lighter in weight, so being also widely used in manufacture machine components and engineering structure.
Steel pipe can be divided into two big classes 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 etc..Seamless steel pipe Fine Steel Casting iron or steel alloy are made, have hot rolling, cold rolling (pulling out) point.Seamless steel pipe can be used for liquid air-pressure duct and the gas pipeline etc. of various industry.Welded pipe line can be used for aqueduct, gas piping, caliduct, electrical equipment pipeline etc..
But, the anti-extrusion poor performance of currently used steel pipe, it is easily deformed in extrusion process, and then affects the further use in later stage.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of Anti-collapse steel pipe, and anti-extrusion performance is good, is unlikely to deform in extrusion process, does not interferes with the further use in later stage.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of Anti-collapse steel pipe, including: steel pipe body, BT-110T casing layer, black filled rubber layer, elastic polyolefin layer, SEW-80TT high collapse strength layer and rare earth composite elastic material layer, the appearance of described steel pipe body is disposed with described BT-110T casing layer outward from interior, described black filled rubber layer and described elastic polyolefin layer, the interior table of described steel pipe body is disposed with described SEW-80TT high collapse strength layer and described rare earth composite elastic material layer inside from outward.
In a preferred embodiment of the present invention, the thickness of described BT-110T casing layer is 4 ~ 6mm.
In a preferred embodiment of the present invention, the thickness of described black filled rubber layer is 5 ~ 7mm.
In a preferred embodiment of the present invention, the thickness of described rare earth composite elastic material layer is 3 ~ 5mm.
The invention has the beneficial effects as follows: the anti-extrusion performance of the present invention is good, is unlikely to deform in extrusion process, do not interfere with the further use in later stage.
Accompanying drawing explanation
