Abstract
A high-density polyethylene corrugated outer protection pipe and double pipe heat insulation pipeline comprises outer protection pipes, work pipes and heat insulation material layers. Each outer protection pipe is an annular high-density polyethylene corrugated pipe, two work pipes are located in each outer protection pipe, and the heat insulation material layers are arranged between each outer protection pipe and two work pipes. The high-density polyethylene corrugated outer protection pipe and double pipe heat insulation pipeline has the advantages that the outer protection pipes are high-density polyethylene corrugated pipes which are high in pressure-bearing capacity and excellent in bending property, do not crack easily and can be manufactured to be disc-shaped for storage, and therefore transportation, storage and construction are convenient; two work pipes are located in each outer protection pipe and can serve as a water supply pipe and a water return pipe, and therefore the construction efficiency is improved, and the laying and occupying area is reduced; the work pipes and the outer protection pipes can form an integrated pipeline through hot-melting connection, and therefore the construction progress is fastened, and the construction cost is lowered.
Description
Technical field:
The invention belongs to a kind of pipeline, particularly the outer two-tube insulation pipe of pillar of a kind of high density polyethylene (HDPE) ripple type, this pipeline is mainly used in central heating system, delivery system, air-conditioning refrigeration system etc.
Technical background:
At present, the structure of moulding cover steel that the outer pillar of insulation pipe most domestic is high density polyethylene (HDPE), thermal insulation layer is polyurethane, working pipe is steel pipe.This structural pipeline Master Cost and operating expenses all higher, and steel pipe is not corrosion-resistant.Also there is Some Enterprises to mould cover and mould single tube insulation pipe, namely working pipe is a plastic tube, the pipeline of this structure scene when constructing need be laid two and mould cover and mould pipeline (waters supply, a backwater), cause equally construct loaded down with trivial details, lay the shortcomings such as floor space is large.In addition, ordinary construction form high-density polyethylene external protective pipe easily ftractures when temperature is lower.
Summary of the invention:
The invention provides the outer two-tube insulation pipe of pillar of a kind of high density polyethylene (HDPE) ripple type, this pipeline fabricating cost and operating expenses is low, construction process simple, long service life.
As above conceive, technological scheme of the present invention is: the outer two-tube insulation pipe of pillar of a kind of high density polyethylene (HDPE) ripple type, comprise outer pillar, working pipe and adiabator layer, it is characterized in that: outer pillar is annular high density polyethylene corrugated type pipeline, two working pipe are positioned at outer pillar, are adiabator layers between outer pillar and two working pipe.
Above-mentioned outer pillar is the circulating line formed by the outer pillar hot-melt adhesive paste of two semicircles.
Above-mentioned two working pipe are placed in the outer pillar of two semicircles respectively, and concentric with the outer pillar of corresponding semicircle.
The present invention has following advantage and good effect:
1, outer pillar of the present invention adopts high density polyethylene (HDPE) ripple type pipeline, bears that pressure is strong, bending properties is excellent, is not easy cracking, is convenient to be made into disk and deposits, transport, deposits and easy construction.
2, there are two working pipe in each outer pillar of the present invention, respectively as water supply and return pipe, efficiency of construction can be improve, reduce to lay floor space.
3, working pipe of the present invention and outer pillar all can adopt hot-melt adhesive paste to form integrated piping, speed up the work, and reduce engineering cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Embodiment:
As shown in the figure: the outer two-tube insulation pipe of pillar of a kind of high density polyethylene (HDPE) ripple type, is made up of outer pillar 1, working pipe 3 and adiabator layer 4.Outer pillar is annular high density polyethylene corrugated type pipeline, and two working pipe are positioned at outer pillar, and centre is adiabator layer.Two working pipe can respectively as water pipe, return pipe, and working pipe and working pipe, working pipe are different and different according to caliber, use with outer pillar spacing.Above-mentioned outer pillar is the circulating line formed by two semicircle pipeline 2 hot-melt adhesive paste.Above-mentioned two working pipe are placed in the outer pillar of two semicircles respectively, and concentric with the outer pillar of corresponding semicircle.
