Abstract
The invention relates to a bendable thermal insulation pipe with a soft polyethylene outer protecting pipe and a bending method. At present, according to thermal insulation pipelines used nationwide, working pipelines are basically made of steel and rigid plastic and have no softness; outer protecting pipes made of high density polyethylene materials according to the standard are insufficient in bendability; particularly, as for small-caliber pipelines, plastic cotton is wrapped outside steel pipes, then plastic tape is wound, and consequently the number of truncation surfaces of the pipelines is large, the number of joints is large, thermal insulation is poor, and high energy consumption waste is caused at last small sections entering rooms of users; in addition, pipeline construction is coarse, and accordingly the service life of a tail pipe network is short. The bendable thermal insulation pipe comprises a bendable working pipe (1), a polyurethane plastic foam thermal insulation layer (2) is arranged on the outer side of the bendable working pipe, a thin-film isolation layer (3) is arranged on the outer side of the polyurethane plastic foam thermal insulation layer, and the soft outer protecting pipe (4) is arranged on the outer side of the thin-film isolation layer. The bendable thermal insulation pipe with the soft polyethylene outer protecting pipe and the bending method are used for thermal insulation pipeline construction.
Description
technical field:
the present invention relates to a kind of flexible software polyethylene outer protective pipe thermal insulation pipe and bending method.
background technique:
at present, the insulation pipe that the whole nation uses, service pipe is steel, hard plastic material substantially, do not have ductility, the high-density polyethylene material that outer pillar adopts by standard, sheathed is not enough, especially small-bore pipeline, is all adopt steel pipe outsourcing plastic cement cotton, is then wound around plastic band, the problem caused is that pipeline truncation surface is many, interface is many, is incubated not good, causes the waste of the energy high consumption at last segment entering user indoor, and pipeline construction is coarse, cause the tip pipe network life-span low.
summary of the invention:
the object of this invention is to provide a kind of flexible software polyethylene outer protective pipe thermal insulation pipe and bending method.
above-mentioned object is realized by following technological scheme:
a kind of flexible software polyethylene outer protective pipe thermal insulation pipe, its composition comprises: flexible working pipe, described flexible working pipe arranged outside has urethane plastic foam heat-insulation layer, described urethane plastic foam heat-insulation layer arranged outside has film insulates layer, and described film insulates layer arranged outside has the outer pillar of software.
described flexible software polyethylene outer protective pipe thermal insulation pipe, described flexible working pipe adopts copper pipe, aluminum pipe or plastic pipe; What described urethane plastic foam heat-insulation layer adopted is highdensity polyurethane combined material; What described outer pillar adopted is the outer pillar of polyethylene outer protective pipe or plastic cement.
the bending method of described flexible software polyethylene outer protective pipe thermal insulation pipe, the structure that this device adopts is the outer pillar of polyethylene outer protective pipe or plastic cement, has pliability; What urethane plastic foam heat-insulation layer adopted is highdensity polyurethane combined material; Service pipe adopts copper pipe, aluminum pipe, plastic pipe, there is flexibility can bend, what adopt due to outer pillar and service pipe is all flexible soft pipeline, so, to use in the process of this device when running into the construction demand of turning, do not need to block to connect again, but directly bending can realization is turned.
beneficial effect:
1., when the present invention can realize large radian, low-angle turning, directly can bend and realize turning, no longer need the pipeline turning problem adding turning link after blocking again.And heat insulation effect is few owing to blocking, and pipeline continuity is good, so temperature keeps, heat insulation effect is good, and save the energy, the pipe network life-span is long; Between urethane plastic foam heat-insulation layer and outer pillar, add film insulates layer play fire retardation, when a fire, protection internal duct, for emergency personnel strives for emergency repair time.
accompanying drawing illustrates:
accompanying drawing 1 is cross-sectional configuration schematic diagram of the present invention.
embodiment:
embodiment 1:
a kind of flexible software polyethylene outer protective pipe thermal insulation pipe, its composition comprises: flexible working pipe 1, described flexible working pipe arranged outside has urethane plastic foam heat-insulation layer 2, described urethane plastic foam heat-insulation layer arranged outside has film insulates layer 3, and described film insulates layer arranged outside has the outer pillar 4 of software.
embodiment 2:
flexible software polyethylene outer protective pipe thermal insulation pipe according to embodiment 1, described flexible working pipe adopts copper pipe, aluminum pipe or plastic pipe; What described urethane plastic foam heat-insulation layer adopted is highdensity polyurethane combined material; What described outer pillar adopted is the outer pillar of polyethylene outer protective pipe or plastic cement.
embodiment 3:
utilize a bending method for the flexible software polyethylene outer protective pipe thermal insulation pipe described in embodiment 1 or 2, the structure that this device adopts is the outer pillar of polyethylene outer protective pipe or plastic cement, has pliability; What urethane plastic foam heat-insulation layer adopted is highdensity polyurethane combined material; Service pipe adopts copper pipe, aluminum pipe, plastic pipe, there is flexibility can bend, what adopt due to outer pillar and service pipe is all flexible soft pipeline, so, to use in the process of this device when running into the construction demand of turning, do not need to block to connect again, but directly bending can realization is turned.
