Dab tsi "Plastic-Coated" Qhov tseeb txhais tau tias yog Kev Tshawb Fawb
"Plastic-coated steel yeeb nkab" yog lub npe dav dav ntau dua li cov khoom lag luam ib leeg - nws yog lub sijhawm cov neeg yuav khoom tshawb nrhiav thaum lawv paub tias lawv xav tau kev tiv thaiv corrosion ntawm cov yeeb nkab tab sis tseem tsis tau tsaws ntawm ib hom txheej lossis txheej txheem. Hauv kev xyaum, nws suav nrog ntau yam txheej txheem sib txawv: yooj yim qhwv PE daim kab xev siv txias dua ib qho primer, extruded ib leeg-txheej PE lub tes tsho, ntau- txheej PE thiab PP tshuab ua rau ntawm epoxy primer, thiab dip - lossis hmoov-paj PVC coatings siv ntau dua nyob rau hauv qhov rooj.
Qhov no tseem ceeb vim tias cov txheej txheem no tsis hloov pauv, thiab kev kho "yas{0}}coated" raws li ib yam khoom ua rau tsis sib haum xeeb. Lub faus roj faus lub ntsiab, laj kab - ncej tes tsho, thiab cable - tiv thaiv kab tag nrho tau hu ua "yas-coated yeeb nkab" hauv kev sib tham sib txawv, tab sis txhua tus xav tau cov txheej txheem sib txawv, thickness, thiab adhesion standard. Nplooj ntawv no tau sau los pab txheeb xyuas qhov ntawd ua ntej koj mus rau qhov tshwj xeeb txheej txheej spec - yog tias koj twb paub lawm tias koj xav tau 3- txheej PE rau cov kev pabcuam xa dej, uas tau them rau qhov tob ntxiv ntawm peb nplooj ntawv 3PE nplooj siab; Yog tias koj xav tau epoxy tshwj xeeb, saib peb nplooj FBE txheej. Nplooj ntawv no yog qeb- qhia qib rau txhua yam hauv qab lub kaus yas-txheej.
Txheej hom piv
| Txheej hom | Qauv | Hom Thickness | Zoo tshaj plaws |
|---|---|---|---|
| PE daim kab xev | Primer + txias - siv PE daim kab xev, qee zaum nrog overwrap | 0.4-0.8 hli | Field- siv kho, tsawg- kev pabcuam nyiaj txiag faus, ua haujlwm luv |
| Extruded ib - txheej PE | Primer + extruded PE tes tsho | 1.0-2.0 hli | General faus piping qhov twg 3PE tsis tau teev tseg |
| 2-txheej PE (2PE) | Adhesive txheej + PE txheej txheej | 1.5-2.5 hli | Nruab nrab -kev tiv thaiv corrosion, laus dua- tiam kav dej spec |
| 3-txheej PE (3PE) | Epoxy primer + nplaum + PE txheej txheej | 2.0-3.5 hli + | Pipeline kev pab cuam, siab -kev cia siab rau faus |
| PP txheej | Cov qauv zoo sib xws rau 3PE, PP tsis yog PE txheej txheej | 2.0-3.5 hli + | Kev kub siab -kev pabcuam kub (PP tiv thaiv kev ua haujlwm siab dua li PE) |
| PVC dip / hmoov txheej | PVC siv los ntawm dip lossis electrostatic hmoov txheej txheem | 0.3-1.0 hli | Lub laj kab, kev ua liaj ua teb, lub teeb - lub luag haujlwm sab hauv / sab nraum zoov cov yeeb nkab |
Txoj kev faib ua feem rau cov neeg yuav khoom feem ntau yog nyob nruab nrab ntawm thaj chaw- siv cov txheej txheem qhwv (pheej yig, ceev, qis dua - lub sijhawm kev ntseeg tau), lub Hoobkas-extruded PE / PP systems (tus nqi siab dua, cov qauv adhesion thiab thickness kuaj, ntev tsim lub neej), thiab dip -coated PVC (ib qhov sib txawv siv 4} rooj plaub, feem ntau yog ib qho zoo li {{4} brasion), lub teeb-lub luag haujlwm huab cua tsis zoo dua li hnyav-lub luag haujlwm hauv av tiv thaiv corrosion).
Yuav siv cov txheej txheem yas li cas
Qhov tseeb ib ntus nyob ntawm hom txheej, tab sis lub Hoobkas -extruded system feem ntau ua raws li tus qauv no:
- Lub hauv paus yeeb nkab raug tua- blasted kom tshem tawm cov nplais thiab ua tiav qhov profile txheej txheej yuav tsum tau ua kom zoo
- Cov yeeb nkab yog preheated rau qhov kub uas yuav tsum tau rau cov primer / nplaum kom fuse kom raug
- Epoxy primer yog thov (rau 3-txheej txheej txheem) thiab kho
- Adhesive txheej yog extruded los yog siv rau primer
- Sab nrauv PE lossis PP txheej yog extruded thiab qhwv ib ncig ntawm cov yeeb nkab thaum tseem kub, sib txuas cov txheej ua ke
- Cov yeeb nkab yog txias, feem ntau los ntawm cov tshuaj tsuag dej, los teeb lub txheej
- Txheej tau tshuaj xyuas - hnub so (pinhole) kuaj nrog siab -voltage spark tester, adhesion tester, thiab thickness ntsuas ntawm ntau lub ntsiab lus raws cov yeeb nkab
- Cov yeeb nkab kawg yog sab laug liab qab rau qhov kev ncua deb (ib qho "cutback") kom tso cai rau qhov chaw vuam, nrog rau qhov sib txawv ntawm cov txheej txheem tom qab los ntawm tshav kub -shrink tes tsho los yog teb- siv qhwv hla lub vuam sib txuas
Daim kab xev- qhwv thiab dip- txheej txheej txheej hla dhau cov txheej txheem extrusion tab sis tseem yuav tsum tau ua kom zoo ntawm qhov chaw npaj - txheej txheej siv hla zeb nplai lossis xeb yuav ua tsis tiav ntawm cov kab ntawv tsis hais seb cov txheej txheem zoo li cas nws tus kheej yog, uas yog ib qho ntawm ntau qhov ua rau ua ntej txheej txheej tsis ua tiav ntawm qis dua - nqi xaj.
FAQ
Q: Qhov txawv ntawm cov yas-coated yeeb nkab thiab PE-coated yeeb nkab yog dab tsi?
A: "Plastic-coated" yog lub ntsiab lus dav dav thiab tuaj yeem xa mus rau PE, PP, lossis PVC txheej siv los ntawm cov txheej txheem sib txawv. "PE-coated" tshwj xeeb txhais tau hais tias cov txheej txheej txheej yog polyethylene, uas yog cov khoom siv yas ntau tshaj plaws rau faus steel yeeb nkab tab sis tsis yog tib qho.
Q: Puas yog txheej txheej yas zoo ib yam li 3PE txheej?
A: Tsis yog - 3PE yog ib qho txheej txheem yas tshwj xeeb (ib qho peb- txheej epoxy/adhesive/PE siv) nyob rau hauv cov yas dav dua - txheej txheej. Cov txheej txheej yas kuj suav nrog ib qho yooj yim dua - txheej, daim kab xev- qhwv, thiab PVC- cov tshuab nqus dej uas tsis ua raws li 3PE cov qauv lossis qib kev ua haujlwm.
Q: Cov yas puas tuaj yeem-coated yeeb nkab tuaj yeem txuas tau?
A: Yog lawm, tab sis cov txheej txheem raug tso tseg ("cutback") rau qhov ncua deb ntawm txhua cov yeeb nkab kawg tshwj xeeb kom tso cai rau vuam, thiab cov vuam vuam sib txuas xav tau nws tus kheej tiv thaiv corrosion tom qab - feem ntau yog cua sov- ntsws lub tes tsho los yog teb- siv cov txheej txheem qhwv nrog rau lub Hoobkas txheej.
Q: Ntev npaum li cas cov yas txheej yuav kav ntev npaum li cas ntawm cov yeeb nkab faus?
A: Qhov no nyob ntawm ntau yam ntawm txheej txheej, daim ntawv thov zoo, thiab cov av / kev pabcuam, tab sis lub Hoobkas-extruded 3PE thiab PP systems feem ntau tau teev tseg rau ntau- xyoo caum tsim lub neej nyob rau hauv kev pab cuam kav dej thaum siv thiab so so- sim, thaum sib dua daim kab xev - qhwv los yog dip- cov txheej txheem siv tau luv luv.
