Qhov txawv ntawm PE thiab PVC conduit yeeb nkab yog dab tsi

Cov yeeb nkab conduit, lub tes tsho hluav taws xob insulated rau kev tsim kho yog lub kaw lus yeeb nkab siv rau hauv kev tiv thaiv thiab ua tiav rau cov kab hluav taws xob, thiab feem ntau yog siv los tiv thaiv cov cables, xov hlau, thiab coj cov kab hluav taws xob hauv cov tsev lossis cov chaw lag luam.

Cov kav dej feem ntau muab faib ua cov kav yas thiab cov kav hlau. Cov kav yas feem ntau suav nrog Cov kav dej PVC thiab cov kav dej PECov kav hlau feem ntau suav nrog rau hauv cov kav KBG thiab cov kav JDG. Nov yog kev qhia txog cov kav yas.

Cov yeeb nkab PVC thiab PE zoo sib xws li cas?

1. Ob qho tib si PVC conduit thiab PE conduit yog tsim los tiv thaiv cov cables thiab cov xov hlau, kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov xov hluav taws xob.

2. Tag nrho lawv muaj kev tiv thaiv corrosion zoo thiab tsim nyog rau qee qhov chaw noo noo thiab corrosive.

3. Ob qho tib si PVC thiab PE cov ntaub ntawv muaj qhov yoog tau yooj yim, uas ua rau lawv muaj qee qhov kev ua tau zoo thaum ntsia, thiab yooj yim hloov kho rau ntau yam duab thiab cov qauv.

4. Feem ntau, cov kav dej PVC thiab PE muaj qee qib ntawm kev tiv thaiv hluav taws (yuav tsum ntxiv cov tshuaj tiv thaiv hluav taws), uas pab txhim kho kev nyab xeeb ntawm cov hluav taws xob.

Qhov txawv ntawm PVC thiab PE conduit yog dab tsi?

1. Cov khoom siv raw sib txawv

- Cov yeeb nkab PVC: ua los ntawm polyvinyl chloride (PVC);
- PE threading yeeb nkab: ua los ntawm polyethylene (PE) khoom.

2. Kev tiv thaiv kub tsawg sib txawv

----PVC conduit: nws yuav ua brittle ntawm qhov kub qis heev;
---- PE threading yeeb nkab: Nws muaj kev tiv thaiv kub thiab tsis kub thiab tsim nyog rau kev siv hauv huab cua txias.

3. Kev cuam tshuam tsis kam:

--- PVC threading yeeb nkab: brittle thiab yooj yim tawg thaum cuam tshuam;
--- PE conduit: Nws muaj kev tiv thaiv zoo thiab tuaj yeem muab kev tiv thaiv ntxiv rau qee qhov chaw nyuaj.

4. Rwb thaiv tsev:

--- PVC conduit: kev ua tau zoo rwb thaiv tsev, hauv cov ntawv thov nrog cov kev xav tau rwb thaiv tsev siab, PVC conduit yog qhov nyiam dua;
--- PE conduit: Piv nrog PVC, kev ua haujlwm rwb thaiv tsev ntawm PE conduit yog dav dua.

5. Cov xwm txheej thov sib txawv:

---PVC threading yeeb nkab: feem ntau yog siv rau hauv kev siv hauv tsev, kev lag luam thiab kev lag luam teeb pom kev zoo;
--- PE conduit: tsim nyog rau qee qhov kev xav tau tshwj xeeb ntawm ib puag ncig, xws li qhov xav tau kev tiv taus txias zoo dua lossis kev tiv taus kev cuam tshuam zoo dua.

Tag nrho hauv txhua qhov, PVC thiab PE conduit muaj lawv tus yam ntxwv, PVC conduit yog siv dav hauv kev siv hauv tsev, kev lag luam thiab kev lag luam me vim nws txoj kev tiv thaiv corrosion zoo, kev ua haujlwm rwb thaiv tsev thiab kev siv nyiaj txiag, thaum PE conduit tau pom cov txiaj ntsig tshwj xeeb hauv qee qhov chaw tshwj xeeb vim nws qhov kub tsis tshua muaj zog, kev cuam tshuam thiab kev ywj pheej.
