Description
Technical field
The present invention relates to steel pipe field, particularly relate to a kind of prefabricated direct-buried steam insulation 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 waterproof impervious characteristic being currently used for prefabricated direct-buried steam insulation steel pipe is poor, and heat loss is big, it is impossible to enough stop
The generation of heat bridge.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of prefabricated direct-buried steam insulation steel pipe, waterproof impervious characteristic
Good, decrease heat loss, it is possible to stop the generation of heat bridge.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of prefabricated direct-buried steam to protect
