Kev ua tau zoo ntawm zawv zawg yeeb nkab fittings ntawm siab lossis qis

Taw qhia:

PEX zawv zawg haum yog hais txog ib hom kev sib txuas lossis haum tshwj xeeb tsim rau polyethylene (PEX) tubing.

Kev ua haujlwm ntawm zawv zawg yeeb nkab fittings ntawm qhov kub siab lossis qis qis yog cuam tshuam los ntawm cov khoom siv yam ntxwv. Cov hauv qab no yog kev soj ntsuam kev ua tau zoo ntawm zawv zawg yeeb nkab fittings hauv ob qhov chaw kub kub:

Kev ua tau zoo ntawm qhov kub thiab txias

Thermal expansion:

Kev kub siab yuav ua rau thermal expansion ntawm cov khoom siv yeeb nkab, uas yuav cuam tshuam qhov loj thiab cov duab ntawm cov yeeb nkab. Nyob rau hauv qhov kub thiab txias ib puag ncig, swb yeeb nkab fittings tej zaum yuav muaj ib tug loj deformation, uas yuav cuam tshuam rau nws installation thiab ua hauj lwm lub xeev.

Txhawm rau tiv thaiv thermal expansion, cov pob qij txha elastic thiab kev txhawb nqa tshwj xeeb tuaj yeem siv los txo qhov kev pheej hmoo ntawm cov yeeb nkab deformation thiab to.

Lub peev xwm nqa:

Nyob rau hauv ib puag ncig kub, lub zog thiab toughness ntawm cov khoom yuav raug txo, uas yuav cuam tshuam rau lub peev xwm ntawm cov yeeb nkab zawv zawg. Hauv kev tsim thiab siv cov zawv zawg yeeb nkab fittings, nws yog ib qho tsim nyog yuav tsum xav txog qhov poob ntawm cov kabmob muaj peev xwm ntawm cov kav dej ntawm qhov kub thiab txias, thiab siv cov kev ntsuas coj los ua kom muaj kev nyab xeeb ntawm cov kav dej.

Thaum tshav kub kub softening:

Thaum qhov kub thiab txias, cov khoom siv yeeb nkab yog qhov ua rau thermal softening, uas tuaj yeem ua rau nkag thiab tawg ntawm cov khoom. Yog li ntawd, nyob rau hauv kev xaiv ntawm cov ntaub ntawv, nws yog tsim nyog los coj mus rau hauv tus account nws kub tsis kam, xws li xaiv ntawm polytetrafluoroethylene (PTFE), silicone, polyester resin thiab lwm yam kub corrosion resistant ntaub ntawv.

Kev ua tau zoo ntawm qhov kub thiab txias

Fragile:

Ntawm qhov kub thiab txias, qee cov khoom ua nkig thiab ua rau tawg. Yog li ntawd, nyob rau hauv kev xaiv ntawm low-temperature zawv zawg yeeb nkab cov ntaub ntawv, nws yog tsim nyog los xav txog nws tsis tshua muaj kub toughness, xws li alloy steel, stainless hlau thiab lwm yam zoo low-temperature toughness.

Daim ntawv cog lus:

Nyob rau hauv sib piv rau thermal expansion, qhov kub tsis tshua muaj ua rau cov khoom siv yeeb nkab ntsws. Qhov shrinkage no tuaj yeem cuam tshuam rau kev sib txuas thiab kev sib khi ntawm cov yeeb nkab thiab yuav tsum tau xav txog thaum tsim thiab teeb tsa.

Kev xaiv cov khoom siv:

Thaum tsis tshua muaj kub, cov ntaub ntawv xws li carbon steel, alloy steel, stainless hlau thiab titanium alloy yog dav siv vim lawv qhov kub tsis zoo thiab corrosion kuj.

xaus

Kev ua tau zoo ntawm zawv zawg yeeb nkab fittings ntawm qhov kub thiab txias yog nyob ntawm cov yam ntxwv ntawm cov khoom xaiv. Thaum qhov kub thiab txias, cov teeb meem ntawm thermal expansion, bearing peev thiab thermal softening yog feem ntau txhawj xeeb. Ntawm qhov kub thiab txias, qhov kev txhawj xeeb tseem ceeb yog qhov brittleness, shrinkage thiab tsis tshua muaj kub toughness ntawm cov khoom. Txhawm rau kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm zawv zawg yeeb nkab fittings nyob rau hauv huab cua kub ib puag ncig, cov ntaub ntawv tsim nyog yuav tsum raug xaiv raws li cov kev thov tshwj xeeb, thiab cov qauv tsim thiab kev teeb tsa yuav tsum raug coj los siv.
