3 LPE Vs. FBE: Xaiv Txoj Cai Kev Tiv Thaiv -Kev Tiv Thaiv Kev Tiv Thaiv Rau Ib puag ncig nyuaj

Hauv qhov tseem ceeb ntawm cov raj xa dej, xaiv qhov zoo tshaj plaws los tiv thaiv- xeb txheej yog qhov kev txiav txim siab uas cuam tshuam rau lub neej ntev, kev nyab xeeb, thiab tus nqi- ua tau zoo ntawm ib qhov project. Rau Longitudinally Submerged Arc Welded (LSAW) thiab High-Frequency Welded (HFW) steel kav, ob txheej txheej txheej txheem feem ntau sawv tawm: Fusion Bond Epoxy (FBE) thiab 3- Txheej Polyethylene (3LPE). Ob leeg muaj kev tiv thaiv zoo tiv thaiv corrosion, tab sis lawv cov yam ntxwv sib txawv ua rau lawv haum rau cov kev siv sib txawv thiab cov teeb meem ib puag ncig. Kev nkag siab txog cov nuances ntawm 3LPE vs. FBE yog qhov tseem ceeb rau cov kws tsim khoom thiab cov thawj coj ntawm kev yuav khoom txhawm rau xaiv txoj cai los tiv thaiv - kev tiv thaiv corrosion rau cov cheeb tsam nyuaj. Hebei Huayang Steel Pipe Co., Ltd., tus kws tshaj lij hauv cov kav dej tiv thaiv corrosion, muab kev sib piv kev tshuaj xyuas los coj cov txheej txheem kev xaiv tseem ceeb no.

Nkag siab txog Core Technologies

Ua ntej delving rau hauv lawv qhov zoo sib piv, nws yog ib qho tseem ceeb kom nkag siab cov qauv tsim thiab kev ua haujlwm ntawm txhua txheej txheej txheej.

Fusion Bond Epoxy (FBE) Txheej

•Structure: Ib txheej -, thermoset epoxy polymer txheej. Nws yog siv los ua cov hmoov qhuav rau cov yeeb nkab steel preheated, qhov twg nws melts, ntws, thiab kho kom tsim ib qho txuas ntxiv, tsis yog - zaj duab xis ntxeem tau.

•Primary Function: Muab cov adhesion zoo heev rau steel nto thiab ua raws li lub hauv paus barrier tiv thaiv corrosion. Nws daim ntawv cog lus tshuaj nrog cov hlau muaj kev tiv thaiv zoo tshaj rau cathodic disbondment thiab tshuaj tua kab mob.

• Cov qauv tseem ceeb: API RP 5L7, ISO 21809-2, NACE SP0394.

3-Layer Polyethylene (3LPE) Txheej

•Structure: Ib txheej txheej ntau - txheej txheej muaj peb txheej sib txawv:

1.Fusion Bond Epoxy (FBE) Primer: Cov txheej sab hauv tshaj plaws, muab kev tiv thaiv corrosion thiab zoo heev adhesion rau hlau.

2.Copolymer Adhesive: Ib txheej nruab nrab uas chemically bonds FBE rau txheej polyethylene txheej.

3.Extruded Polyethylene (PE): Cov txheej txheej sab nraud uas muaj zog, feem ntau yog siab - ntom polyethylene (HDPE) lossis nruab nrab - ntom polyethylene (MDPE), muab kev tiv thaiv txhua yam.

•Primary Function: Muaj kev tiv thaiv zoo los ntawm kev sib txuas cov kev tiv thaiv corrosion ntawm FBE nrog cov khoom siv zoo tshaj plaws thiab kev tiv thaiv ib puag ncig ntawm polyethylene.

• Cov qauv tseem ceeb: DIN 30670, ISO 21809-1, NACE SP0188.

Kev sib piv: 3LPE vs. FBE

Thaum ob qho tib si FBE thiab 3LPE muaj txiaj ntsig zoo los tiv thaiv- cov txheej txheem corrosion, lawv cov yam ntxwv ntawm kev ua tau zoo sib txawv, ua rau ib qho tsim nyog dua li lwm qhov nyob ntawm qhov tshwj xeeb yuav tsum tau ua thiab ib puag ncig.

1. Mechanical Protection

•FBE: Ua ib txheej txheej nyias nyias, FBE muaj kev cuam tshuam rau kev puas tsuaj (xws li, cuam tshuam, puas, av nyuaj) thaum tuav, teeb tsa, thiab ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv cov pob zeb lossis abrasive xau. Nws feem ntau xav tau kev tiv thaiv ntxiv (piv txwv li, pob zeb txheej, pob zeb thaiv).

•3LPE: Cov txheej tuab txheej polyethylene muab kev tiv thaiv zoo tshaj plaws. Nws muaj kev tiv thaiv zoo heev rau kev cuam tshuam, kev puas tsuaj, thiab kev ntxhov siab hauv av, ua rau nws zoo heev rau kev teeb tsa hnyav (xws li, trenchless installation, rocky terrains) thiab aggressive av tej yam kev mob.

2. Corrosion Resistance & Adhesion

•FBE: Muab cov adhesion zoo rau cov hlau thiab superior tiv thaiv cathodic disbondment, ua rau nws yog ib qho zoo heev tiv thaiv corrosion. Nws kuj muaj tshuaj tiv thaiv zoo.

•3LPE: Cov txiaj ntsig los ntawm FBE txheej rau kev tiv thaiv corrosion thiab cathodic disbondment kuj. Cov txheej PE txheej ntxiv tiv thaiv FBE los ntawm kev puas tsuaj rau lub cev, ua kom muaj kev ncaj ncees ntawm kev tiv thaiv corrosion nyob rau lub sijhawm ntev.

3. Kev khiav hauj lwm qhov kub thiab txias

•FBE: Feem ntau haum rau kev khiav hauj lwm kub, feem ntau mus txog 110℃(230℃F), nrog ib co siab - kub FBE formulations muaj peev xwm txawm ntau dua. Qhov no ua rau nws yog qhov kev xaiv zoo rau cov roj kub thiab cov kav dej.

•3LPE: Tus txheej txheem polyethylene txheej txheej txwv nws qhov siab tshaj plaws kev khiav hauj lwm kub, feem ntau mus txog 80℃(176℃F). Rau qhov kub siab dua, 3-Layer Polypropylene (3LPP) yog siv, uas tuaj yeem tiv taus txog 140℃(284℃F).

4. Daim ntawv thov complexity & nqi

•FBE: Cov txheej txheem thov yooj yim, feem ntau xav tau cov cuab yeej siv tsawg thiab qhov chaw ntau dua 3LPE. Feem ntau txo cov khoom siv thiab cov nqi siv.

•3LPE: Cov txheej txheem thov ntau dua vim peb cov txheej txheem sib txawv thiab kev tswj xyuas qhov kub thiab txias yuav tsum tau ua. Cov khoom siv thiab cov nqi siv ntau dua piv rau FBE.

5. Field Joint Txheej

•FBE: Kev sib koom ua ke ntawm cov kav dej FBE feem ntau suav nrog cov kua epoxies lossis cua sov- lub tes tsho ntsws.

•3LPE: Field coating coatings rau 3LPE kav feem ntau siv tshav kub-shrink tes tsho los yog teb- siv polyurethane/polyethylene systems kom phim cov neeg kho tshuab kev tiv thaiv ntawm lub ntsiab kab txheej.

 

 

Xaiv txoj kev daws teeb meem rau koj ib puag ncig

Qhov kev txiav txim siab ntawm 3LPE thiab FBE yuav tsum yog raws li kev soj ntsuam tag nrho ntawm qhov project- tej yam tshwj xeeb:

•Environmental Severity: Rau cov av abrasive heev, pob zeb terrains, los yog tej thaj chaw muaj kev puas tsuaj rau sab nraud, 3LPE muaj superior mechanical tiv thaiv.

• Ua Haujlwm Kub: Rau cov kav dej thauj cov dej kub (siab dua 80 degree), FBE lossis 3LPP (yog tias muaj kev tiv thaiv kev siv tshuab tseem ceeb) yuav tsim nyog dua.

•Installation Method: Trenchless installations (piv txwv li, HDD) feem ntau tau txais txiaj ntsig los ntawm kev tiv thaiv zoo ntawm 3LPE.

•Project Budget & Lifespan: Thaum 3LPE muaj tus nqi pib dua, nws txoj kev ruaj khov thiab kev ua neej ntev dua tuaj yeem ua rau lub neej qis dua - cov nqi mus rau hauv cov cheeb tsam nyuaj.
