Abstract
The invention discloses a steel pipe for a pipeline. The steel pipe comprises a steel pipe body, a high impact polystyrene/microcapsule red phosphorus/exfoliated graphite flame resistant material layer, a polystyrene/diatomite /composite flame resistant material layer, a nylon 6/ modified MCA halogen-free flame resistant material layer and a halogen-free flame resistant polypropylene/polyurethane elastomer composite layer, wherein the high impact polystyrene/microcapsule red phosphorus/exfoliated graphite flame resistant material layer and the polystyrene/diatomite/chlorcosane composite flame resistant material layer are sequentially arranged on the outer surface of the steel pipe body from inside to outside; and the nylon 6/modified MCA halogen-free flame resistant material layer and the halogen-free flame resistant polypropylene/polyurethane elastomer composite layer are sequentially arranged on the inner surface of the steel pipe body from outside to inside. Through the manner, the steel pipe disclosed by the invention is good in flame resistance, and the safety performance of the pipeline can be improved.
Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of pipeline steel pipe.
Background technology
Steel pipe is the strip steel of a kind of hollow, and 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 work
Journey 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..Nothing
Seam steel pipe Fine Steel Casting iron or steel alloy make, have hot rolling, cold rolling (pulling out) point.Seamless steel pipe can be used for the liquid of various industry
Bromhidrosis pressure pipeline and gas pipeline etc..Welded pipe line can be used for aqueduct, gas piping, caliduct, electrical equipment pipeline etc..
But, the fire resistance of current pipeline steel pipe has much room for improvement, it is impossible to enough improve the security performance of pipeline.
