3PP Coated SAWL yeeb nkab yog dab tsi?
3 PP coated SAWL yeeb nkabyog ib tug longitudinal submerged arc welded steel yeeb nkab tiv thaiv nrog peb - txheej polypropylene txheej txheej txheej txheej.
LSAW stands forLongitudinal Submerged Arc Vuam. LSAW cov kav dej feem ntau yog siv rau loj - txoj kab uas hla thiab siab - lub zog siv cov kav dej vim tias lawv tuaj yeem tsim tau nrog kev tswj xyuas qhov tseeb thiab tsim cov phab ntsa tuab rau kev xav tau kev sib kis.
Hom 3PP txheej txheej txheem
Hlau Yeeb Nkab → FBE Primer → Copolymer Adhesive → Polypropylene Txheej Txheej
| Txheej Txheej | Khoom siv | Lub luag haujlwm tseem ceeb |
|---|---|---|
| Thawj Txheej | FBE | Kev tiv thaiv corrosion thiab adhesion rau hlau |
| Ob Txheej | Copolymer Adhesive | Kev sib raug zoo ntawm FBE thiab PP |
| Thib peb | Polypropylene (PP) | Siab - kub thiab kev tiv thaiv txhua yam |
3PP vs 3PE: Qhov txawv loj tshaj yog dab tsi?
Qhov tseem ceeb tshaj qhov sib txawv ntawm3PP thiab 3PE txheejyog qhov kev ua tau zoo ntawm lawv cov thermoplastic txheej txheej.
- 3PE sivpolyethylene (PE)raws li cov txheej txheem tiv thaiv sab nrauv.
- 3 PP sivpolypropylene (PP)raws li cov txheej txheem tiv thaiv sab nrauv.
Qhov kub thiab txias ntawm 3PE thiab 3PP
| Txheej Khoom | 3PE (Peb-Txheej Polyethylene) | 3PP (Peb- Txheej Polypropylene) |
|---|---|---|
| Yam tsawg kawg nkaus ua haujlwm Temp. | -40 degree(Zoo heev low -temp yooj) | -20 degree(Ua nkig hauv qhov txias txias) |
| Kev khiav hauj lwm kub siab tshaj plaws. | +60℃rau +80 degree(Peaks ntawm 85 degree) | +80℃rau +110 degree(High -kub kua) |
| Qhov zoo tshaj plaws suited rau ... | Standard roj, roj, thiab dej kab | Roj kub, chav condensate, thiab cheeb tsam cua sov |
3PE vs 3PP ntawm ib nrais muag
| Yam ntxwv | 3 PE txheej | 3 PP txheej |
|---|---|---|
| Txheej txheej | Polyethylene(PE) | Polypropylene(PP) |
| Kev tiv thaiv corrosion | Zoo heev | Zoo heev |
| Mechanical tiv thaiv | Zoo heev | Zoo heev |
| Kub tiv taus | Zoo | Siab dua |
| High -kev thov kub | Limited los ntawm PE system | Zoo dua |
| Kub roj pipeline | Qhov project nyob ntawm | Tshwj xeeb yog tsim nyog |
| Siab -kub faus cov kav dej | Qhov project nyob ntawm | Feem ntau xav txog |
| Geothermal applications | Kev thov nyob ntawm | Haum rau kev xaiv siab - qhov kub thiab txias |
| Middle East siab -kub oilfield | Feem ntau rau nruab nrab kub | Kev xaiv muaj zog rau qhov kub siab dua |

Qhov txiaj ntsig tseem ceeb ntawm polypropylene yog nwsmuaj peev xwm kub duapiv nrog cov pa polyethylene txheej txheej txheem.

Qhov noua rau 3PP yog tus neeg sib tw muaj zog rau cov ntawv thov uas cov kav dej ua haujlwm kub Tshaj li qhov ntsuas kub ntawm qhov ua tau zoo ntawm 3PE qhov system.
Vim li cas 3PP Zoo Tshaj rau High -Cov kav dej kub?
Polypropylene muaj qhov melting point ntau dua thiab kev pabcuam siab dua -kub muaj peev xwm tshaj li cov khoom siv polyethylene.Qhov no muab 3PP nrog ib qho tseem ceeb kom zoo dua thaum cov txheej txheej sab nraud raug rau cov kav dej kom siab rau lub sijhawm ntev.
Rau cov kav dej faus, cov txheej tuaj yeem raug:
- Kev khiav hauj lwm kub tsis tu ncua
- Luv -lub sij hawm kub siab tshaj
- Thermal cycling
- Av kub hloov
- Thaum tshav kub kub hloov los ntawm qhov nruab nrab thauj
- Mechanical stress los ntawm thermal expansion thiab contraction
Ntawm qhov kub siab, cov khoom siv txheej yuav tsum tswj kom txaus:
- Adhesion
- Mechanical zog
- Dimensional stability
- Resistance rau deformation
- Resistance rau disbondment
- Ntev - lub sij hawm txheej kev ncaj ncees
3PP rau Middle East High -Tsub Roj Fields
Oilfield thiab pipeline tej yaam num nyob rau hauvMiddle Eastxws li Saudi Arabia, United Arab Emirates, Kuwait, Iraq thiab Oman tuaj yeem koom nrog:
- Kub ambient kub
- Hnub ci hluav taws xob siab
- Suab puam av
- Cov av kub
- Ntev -qhov deb faus cov kav dej
- Crude roj tsheb thauj mus los
- Kev thauj mus los hnyav
- Oilfield sib sau ua ke systems
- High -tej txheej txheem cov kav dej kub
Hauv cov cheeb tsam no, kev xaiv txheej yuav tsum xav txog ob qho tib sipipeline khiav hauj lwm kubthiabsab nraud ib puag ncig kub.
Rau siab - daim ntawv thov cov roj av kub lossis cov kav dej kub, cov kav dej kub kub faus, 3PP tuaj yeem txiav txim siab thaum qhov kev khiav hauj lwm kub yuav tsum tau siab dua - kub txheej txheej txheej sab nraud dua li cov pa 3PE tuaj yeem muab tau.
