PEX Floor Heating Pipe vs Mhangura /PE-RT Pipe

Mune yakaderera-tembiricha inopenya pasi yekudziya system, mapaipi akafanana netsinga dzeropa dzemuviri wemunhu, inobata zvakananga kupisa kushanda, kushandiswa kwesimba uye ruzivo rwekushandisa kwenguva refu. Nekufambira mberi kwezvinhu tekinoroji, PEX (crosslinked polyethylene) pombi, pombi yemhangura uye PE-RT (high tembiricha inodzivirira polyethylene) pombi dzave sarudzo dzakanyanya. Muchinyorwa chino, isu tichaenzanisa zviyero zvina zvehunhu hwezvinhu, corrosion resistance, thermal conductivity kunyatsoita uye kuisirwa mutengo kukubatsira iwe kuita sarudzo dzinodhura.

Chekutanga, kuenzanisa kwezvinhu: flexibility, upenyu nekuchengetedzwa kwezvakatipoteredza

1.PEX uriri kupisa pombi: kuenzanisa kwekushanduka uye kusimba ,

PEX pombi dzakabatanidzwa kuita matatu-dimensional mesh chimiro chinosanganisa kuchinjika uye simba re polyethylene.. Zvakanakira zvayo zvinosanganisira:

,Deformation resistance: -70℃ ~ 110 ℃ kushivirira siyana, inogona kuramba pasi kudziyisa kutenderera kutonhora uye kupisa kuvhunduka.

,Mkusimba mupfungwa: inogona kupora yega mushure mekubatwa netsaona panguva yekuvaka kuderedza njodzi yekudonha.

Kuchengetedzwa kwezvakatipoteredza: hapana njodzi yekunaya kweheavy metal, zvinoenderana neEuropean Union RoHS standard.

2.Cpombi yepamusoro: miganhu yechinyakare simbi pombi ,

Pipe yemhangura inozivikanwa nekukwirira kwayo kwekushisa, asi pane zvikanganiso zviri pachena:

,High kuoma, yakaoma kukotama: vanoda nhamba huru yemajoini, kuwedzera mukana wekudonha.

Oxidation uye electrolytic corrosion: kunyanya mumvura ine alkaline kana sarufa iri nyore kugadzira patina.

,Cost-sensitive: Mutengo wezvinhu zvakasvibiswa unokanganiswa zvakanyanya nekushanduka-shanduka kwemutengo wemhangura wepasi rose.

3.PE-RT chubhu: iyo yepakati sarudzo yekudhura-inoshanda ,

PE-RT inonatsiridza tembiricha kuramba kuburikidza nemolecular chimiro shanduko, asi zvichienzaniswa nePEX:

Weak pressure resistance: zviri nyore kukambaira pasi penguva refu yekupisa kwepamusoro, uye hupenyu hwayo hwesevhisi huri pamusoro 20-30 makore (PEX inogona kusvika kupfuura 50 makore).

,Lyakateedzerwa application scenario: yakawanda yakakodzera kune yakaderera tembiricha yekudziya system pazasi 60 ℃.

Mhedziso: PEX inokunda muhupenyu uye kuchinjika, kunyanya yakakodzera kugoverwa kwepombi yakaoma.

Corrosion resistance: muedzo wekupedzisira wehutano hwemvura uye zvakatipoteredza

PEX chubhu: mambo wemakemikari inertia

Hapana mhinduro kune acid, alkali uye munyu mhinduro (pH 2-12), chloride ions, hapana chikonzero chekuchenesa nguva dzose.

Nyaya: 90% yekudziya kwepasi muNorthern Europe inoshandisa mapaipi ePEX kubata nemvura yakakwira yemamineral pasi pasina kumanikidzwa.

Pombi yemhangura: inogona kuita minefield yengozi yekuora ,

Electrochemical corrosion: zviri nyore kugadzira bhatiri renzvimbo mumvura ine yakakwira okisijeni.

Sulfid corrosion: mvura mune dzimwe nzvimbo dzeChina ine sulfuri yakawanda, izvo zviri nyore kuumba dema mhangura sulfide scale.

Mari yekuchengetedza: unoda kuwedzera corrosion inhibitor nguva dzose, mari yekuchengetedza yegore negore inenge 300-500  /100㎡.

PE-RT chubhu: kugadzikana kwakaderera kune PEX,

Mushure mekushandisa kwenguva refu, inogona kukonzera kukanganisa nekuda kweoxidation, uye chibatanidza chiri nyore kutsemuka.

Mhedziso: PEX inenge isina kugadzirisa, kunyanya yakakodzera kune yakaoma mvura yemhando yemamiriro ekunze muChina.

Thermal conductivity Efficiency: Kusanzwisisa “simbi inobatsira”

1.Dkana kuenzanisa

2.Metal thermal conductivity ≠ chaiyo mukana ,

Thermal inertia: pombi yemhangura ine simba rekuchengetedza kupisa, zvichiita kuti kupisa kunonoka kukwira/kutonhora, izvo zvisingakwanisi kugadzirisa tembiricha yakarurama.

Okubviswa nekurasikirwa nekupisa: iyo chubhu yemhangura inoda kuwedzera kwekudzivirira (20% mari yakawanda), uye PEX ine low thermal conductivity.

Uniformity: PEX machubhu anogona kukwenenzverwa-kukochekerwa kuti atsivise mutsauko wekupisa wekupisa uye kuwana kwakaringana kupisa kupisa..

Mhedziso: Iyo chaiyo yekupisa mhedzisiro yePEX iri padyo neiyo yemhangura chubhu, uye simba rekuchengetedza rinovandudzwa ne 10%-15%.

Mari yekuisa: kodhi yekuchengetedza mari yemapurojekiti akavanzika

Coprehensive cost kuenzanisa (kutora 100㎡ imba semuenzaniso) ,

PEX mabhenefiti ekuvaka ,

,Single pipe inoramba ichiisa: hapana magadzirirwo akabatanidzwa kuderedza 90% leakage points.

Tool simplification: special clamping tool instead of copper pipe welding, shorten the construction period by 40%.

High fault tolerance: support non-professional DIY repair (such as the use of hot melt sleeve).

Mhedziso: The comprehensive cost of PEX is only 1/3 of that of copper pipe, and the later maintenance is almost zero investment.

Final Choice: Why is PEX the future Trend?

1.Trends from industry data ,

PEX will account for 68% of the global floor heating pipe market in 2025 (data source: GIA report).

The adoption rate of PEX in newly installed residential floor heating systems in China jumped from 32% mu 2015 ku 79% mu 2025.

2.Scenario-based recommended ,

Preferred PEX‌: suitable for 90% of families, especially the transformation of old houses and complex units.

Carefully select copper pipe: It is only recommended for commercial places (such as gyms) with UHF start and stop, uye hurongwa hwemvura yakapfava hunodiwa.

PE-RT imwe nzira: nzvimbo dzemaodzanyemba dzine bhajeti shoma shoma uye mwaka pfupi wekudziya.

Iyo iterative chimiro chepasi pevhu yekudziya pombi ndeyekusimudzira mukukosha kwemushandisi — PEX inowana kuvimbika kwepamusoro pamutengo wakaderera, inova musanganiswa wakakwana wezvinhu sainzi uye huchenjeri hweinjiniya.
