Abstract
The invention relates to a steel-plastic composite pipe, which comprises a hollow body (1), and is characterized in that: the bottom of the hollow body (1) is provided with a heat-insulating layer (2) which is made of plastic generally and polypropylene random copolymer (PPR) plastic preferably; and the hollow body (1) is made of stainless steel preferably. The steel-plastic composite pipe has the advantages of high firmness and strength and good heat-insulating effect.
Description
Technical field
The invention relates to a kind of steel-plastic composite pipe.
Background technique
The hollow aluminum strip is one of main material in the energy-conservation double glazing, and molecular sieve desiccant is put in inside, and the double glazing sealed space is kept dry.But at present used hollow aluminum strip forms with the aluminium extruding, and fastness and intensity are lower; In addition, energy-conservation double glazing is high to heat insulation requirement, and the thermal conductivity of aluminium is higher, and effect of heat insulation is poor, and this just need be improved with other material.
Summary of the invention
The invention technical problem to be solved is: provide a kind of fastness and intensity higher, effect of heat insulation can substitute the steel-plastic composite pipe of hollow aluminum strip preferably.
The technological scheme of the invention is: steel-plastic composite pipe, comprise hollow article, and it is characterized in that a thermal-protective coating is arranged at the hollow article bottom, thermal-protective coating is generally plastics, is preferably the PPR plastics, and hollow article is preferably stainless steel.
The advantage of the invention: fastness and intensity are higher, and effect of heat insulation is better.
