Description
Technical field
The utility model is related to pipe technology field, and in particular to a kind of hot and cold water XRT70 cold-contraction type lining plastic aluminium alloy
Pipe and pipe-line system.
Background technology
Hot and cold water was studied first with heat-proof polythene (PE-RT) pipeline material by Tao Shi (DOW) chemical companies before 20 years
Develop and apply, at present in addition to DOW Chemical, Ling Youduo companies can commercially produce, such as Dao Daer petrochemical industry, Basel with
And South Korea SK and LG.The English full name of heat-proof polythene (PE-RT) is " PolyEthylene of Raised Temperature
resistence”.It is different according to comonomer, it is divided into ethene common with octene copolymer heat-proof polythene (C2+C8), ethene and hexene
Poly- heat-proof polythene (C2+C6) and the heat-proof polythene (C2+C4) of ethene and butene.
Heat-proof polythene (PE-RT) has excellent long-term hydrostatic strength without crosslinking；With weldability, and can
Using all welding process；PE-RT material impact strengths are fabulous, and pliability and long-term creep behaviour are good, with
Good low temperature resistant (- 40 DEG C) performance of conventional high-density polyethylene identical, the minimum operating temperature of long-term work is -20 DEG C,
And energy high temperature resistant, therefore suitable for industrial and civil buildings hot and cold water pipeline system, potable water system, ground radiation heating system
System and high temperature earth-source hot-pump system.
Recent years, the application of PE-RT pipelines and the development of the pipeline material technology are all very rapid, from pipeline
For in terms of raw material, in addition to PE-RT I type raw material, the more preferable PE-RT II type raw material of long-term hydrostatic strength
It is developed, and supplier at least 3.From the point of view of the hot and cold water plastic pipe market of domestic current, lower cost must
Cost must be dropped to the combination property of system, on the other hand be also limited by the Some features of pipeline material itself, such as：Low temperature
The high tubing of intensity, possible elevated temperature strength is not good enough, such as PP-R, and the minimum desired strength of its 20 DEG C/50 years is about 9.8MPa,
The minimum desired strength of 70 DEG C/50 years is about 3.3MPa, and it is hydrostatic expected intensity curve of the material in high temperature intuitively to embody
Slope ratio it is larger, i.e., intensity declines very fast；The good tubing of heat-resisting quantity may be restricted in low temperature using field, such as PP-R
Black brittleness；The tubing of low temperature performance well is restricted in the use of high-temperature field, and the long-term of such as polyethylene (such as PE100) makes
40 DEG C are no more than with temperature；Construction environment is generally severe so that tubing, which pulls phenomenon, often to be occurred, so as to most probably cause tubing
There is cut in outer wall, and these cuts, together with the position such as at mechanical junction and hot-melt adhesive paste melt fusion, are all easy formed
Stress concentration and cracking position, and pipeline material resistance to slow crack growth poor performance in itself.
In tubing field, the material that carrying out resistance to cracking earliest can study is polyethylene family material, and by research table
Bright, the resistance to slow crack growth performance of ethene and hervene copolymer polyethylene is best.Therefore, the utility model provides a kind of hot and cold water
With XRT70 cold-contraction types plastics-lined aluminium alloy pipe and pipe-line system.
