Abstract
Shock resistance type PP-R pipe, comprise pipe in PP-R, it is characterized in that, in described PP-R, pipe periphery is also provided with shock resistance type PP-R outer tube.The utility model adopts inside and outside two-tube combining structure, and shock resistance type PP-R outer tube has good impact resistance and heat distortion temperature, reaches the object of the low temperature brittleness reducing PP-R pipe, makes the utility model can adapt to job site low temperature environment.
Description
Technical field
The utility model relates to tubing field, particularly a kind of shock resistance type PP-R pipe being applicable to feedwater and field of heating.
Background technique
PP-R pipe has energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, the advantage such as inner wall smooth non-scaling, construction and maintenance is easy, long service life, be widely used in building industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and cable sheath, industrial fluids conveying, agricultural irrigation, but, there is the shortcoming of low-temperature impact property difference, this main manifestations under cryogenic, PP-R pipe shows fragility, and because PP-R itself has certain toughness, for construction and use bring significant limitation.
Model utility content
The purpose of this utility model is the deficiency and the defect that there is low-temperature impact property difference for existing PP-R pipe, provides a kind of PP-R pipe of shock resistance type, to solve the problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Shock resistance type PP-R pipe, comprise pipe in PP-R, it is characterized in that, in described PP-R, pipe periphery is also provided with shock resistance type PP-R outer tube.
In a preferred embodiment of the present utility model, be provided with refractory layer between pipe in described shock resistance type PP-R outer tube and described PP-R, the outer wall of described shock resistance type PP-R outer tube is provided with thermal insulation layer.
Shock resistance type PP-R outer tube adopts beta crystal-type nucleater to be combined the PP-R made with PP-R material to manage, the effect of beta crystal-type nucleater is the beta crystal generating hexahedron, increase the impact resistance of PP-R pipe and improve the heat distortion temperature of PP-R pipe, and utilizing beta crystal-type nucleater to be combined the technique the making PP-R pipe technology known known to those skilled in the art with PP-R material.
Owing to have employed technological scheme as above, the utility model adopts inside and outside two-tube combining structure, and shock resistance type PP-R outer tube has good impact resistance and heat distortion temperature, reach the object of the low temperature brittleness reducing PP-R pipe, make the utility model can adapt to job site low temperature environment.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Embodiment 1
Shock resistance type PP-R pipe shown in Figure 1, comprise pipe 10 and the shock resistance type PP-R outer tube 20 being arranged on pipe 10 periphery in PP-R in PP-R, shock resistance type PP-R outer tube 20 adopts beta crystal-type nucleater to be combined the PP-R made with PP-R material to manage, the effect of beta crystal-type nucleater is the beta crystal generating hexahedron, increase the impact resistance of PP-R pipe and improve the heat distortion temperature of PP-R pipe, and utilizing beta crystal-type nucleater to be combined the technique the making PP-R pipe technology known known to those skilled in the art with PP-R material.
The present embodiment adopts inside and outside two-tube combining structure, and shock resistance type PP-R outer tube 20 has good impact resistance and heat distortion temperature, reaches the object of the low temperature brittleness reducing PP-R pipe, makes the present embodiment can adapt to job site low temperature environment.
Embodiment 2
The present embodiment is roughly the same with embodiment 1 structure, and its difference is, be provided with refractory layer 30 between pipe 10 in shock resistance type PP-R outer tube 20 and PP-R, the outer wall of shock resistance type PP-R outer tube 20 is provided with thermal insulation layer 40.The present embodiment is except can reaching the technique effect of embodiment 1, also there is following outstanding effect: the thermal insulation layer 40 arranged at shock resistance type PP-R outer tube 20 outer wall further increases low-temperature impact property, ensure that tubing can normally work for a long time, and refractory layer 30 is provided with between pipe 10 in shock resistance type PP-R outer tube 20 and PP-R, improve the serviceability temperature 20 DEG C of conventional P P-R tubing, extend the working life of tubing.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
