Multi-Txheej Txheej Zoo: Vim li cas 3LPE Txheej yog Tus Qauv Kub Rau Cov Kav Dej

Nyob rau hauv lub network loj ntawm lub ntiaj teb no lub zog thiab kev thauj mus los, faus steel pipelines yog indispensable. Txawm li cas los xij, cov hlab ntsha tseem ceeb no niaj hnub nyob rau hauv kev tawm tsam los ntawm kev txhoj puab heev hauv av ib puag ncig, ua rau corrosion ua rau muaj kev hem thawj rau lawv txoj kev ncaj ncees thiab kev ua haujlwm. Txhawm rau tiv thaiv cov kev nqis peev loj no thiab ua kom cov kev pabcuam tsis muaj kev cuam tshuam, kev tiv thaiv kev tiv thaiv zoo - kev tiv thaiv corrosion tsis yog ib qho kev xaiv nkaus xwb tab sis yog qhov tseem ceeb. Ntawm cov txheej txheem ntau lawm, 3- Txheej Polyethylene (3LPE) txheej tau tshwm sim raws li tus qauv kub rau faus cov kav dej, tshwj xeeb tshaj yog rau Longitudinally Submerged Arc Welded (LSAW) thiab High-Frequency Welded (HFW) steel kav. Yog li, dab tsi yog qhov zoo ntawm ntau- txheej txheej uas ua rau 3LPE txheej yog qhov nyiam xaiv, thiab vim li cas nws thiaj suav tias yog qhov ntsuas ntsuas rau kev tiv thaiv cov kav dej faus? Hebei Huayang Steel Yeeb Nkab Co., Ltd., uas yog lub chaw tsim khoom ntawm cov kav hlau tiv thaiv corrosion, delves rau hauv kev tshawb fawb thiab cov txiaj ntsig tom qab qhov kev tiv thaiv zoo tshaj no.

Qhov Kev Sib Tw Tsis Txaus Siab ntawm Underground Corrosion

faus pipelines ntsib ib tug complex array ntawm corrosive yam:

•Soil Chemistry: Ntau qib pH, muaj cov ions txhoj puab heev (chlorides, sulfates), thiab organic acids.

•Moisture Content: Dej ua raws li cov electrolyte, ua kom yooj yim electrochemical corrosion.

•Soil Resistivity: Tsawg resistivity xau ua kom cov nqi corrosion.

• Kev Ua Haujlwm Microbial: Qee cov kab mob (xws li sulfate- txo cov kab mob) tuaj yeem ua rau microbiologically cuam tshuam corrosion (MIC).

•Mechanical Stress: Av txav, pob zeb impingement, thiab installation stresses tuaj yeem ua rau cov coatings puas.

•Cathodic Protection (CP) cuam tshuam: Txheej txheej yuav tsum ua haujlwm sib koom ua ke nrog CP systems, tiv thaiv cathodic disbondment.

Cov kev cov nyom no yuav tsum muaj cov txheej txheem txheej txheej uas muaj kev qhia dav, ntev - kev tiv thaiv ntev.

Nkag siab txog 3LPE Multi- Txheej Txheej Txheej Txheej

Lub zog ntawm 3LPE txheej nyob rau hauv nws cov synergistic peb - txheej txheej, txhua txheej ua rau cov khoom sib txawv los tsim ib qho impermeable thiab mechanically robust barrier. Cov txheej txheem no feem ntau siv rau cov kav hlau steel raws li cov qauv thoob ntiaj teb xws li DIN 30670, ISO 21809-1, thiab NACE SP0188.

Txheej 1: Fusion Bond Epoxy (FBE) - Thawj Corrosion Barrier

•Composition: Ib txheej nyias (feem ntau 60-100 microns) ntawm thermoset epoxy hmoov.

•Function: Applied ncaj qha mus rau lub meticulously ntxuav thiab rhuab steel nto, FBE muab zoo heev adhesion thiab ua raws li thawj anti{0}}corrosion barrier. Nws daim ntawv cog lus tshuaj nrog cov hlau muaj kev tiv thaiv zoo tshaj rau cathodic disbondment thiab tshuaj tua kab mob.

• Cov txiaj ntsig zoo: Kev ua haujlwm siab adhesion, zoo heev corrosion kuj, tshuaj lom neeg ua haujlwm zoo, thiab muaj peev xwm ua haujlwm kub.

Txheej 2: Copolymer Adhesive - Tus neeg saib xyuas Bonding

•Composition: Ib co-polymer nplaum txheej (feem ntau 150-250 microns) uas yog tshav kub-extruded tshaj FBE kho.

•Function: Cov txheej txheem no sib txuas nrog FBE thiab txheej txheej polyethylene, ua kom muaj zog, txuas ntxiv ntawm peb txheej. Nws tiv thaiv delamination thiab tswj kev ncaj ncees ntawm tag nrho cov kab ke.

•Qhov zoo: Zoo heev adhesion rau FBE thiab polyethylene, ua kom cov txheej cohesion.

Txheej 3: Extruded Polyethylene (PE) - Cov Mechanical thiab Environmental Shield

•Composition: Ib txheej txheej (feem ntau 1.8-3.7 hli, nyob ntawm cov yeeb nkab txoj kab uas hla) ntawm siab -density polyethylene (HDPE) los yog medium-density polyethylene (MDPE).

•Function: Cov txheej txheem no muaj kev tiv thaiv tshwj xeeb tiv thaiv kev puas tsuaj, cuam tshuam, thiab kev ntxhov siab hauv av thaum tuav, teeb tsa, thiab ua haujlwm. Nws kuj tseem muaj cov hluav taws xob rwb thaiv tsev zoo heev, tiv thaiv UV (rau saum- ntu hauv av), thiab tiv thaiv kev nqus dej.

•Qhov zoo: Cov khoom siv zoo tshaj plaws, muaj kev cuam tshuam zoo, kev ua haujlwm zoo heev, UV ruaj khov, thiab dej tsis tshua muaj permeability.

Vim li cas 3LPE yog Tus Qauv Kub

Kev sib xyaw ntawm peb txheej no muab ib theem ntawm kev tiv thaiv uas ib zaug - txheej txheej tsis tuaj yeem phim:

•Comprehensive Corrosion Protection: FBE muab cov electrochemical barrier, thaum PE tiv thaiv lub cev puas tsuaj uas yuav cuam tshuam rau FBE.

•Superior Mechanical Protection: Cov txheej txheej PE tuab tiv thaiv lub hauv paus FBE los ntawm kev puas tsuaj, av kev ntxhov siab, thiab kev cuam tshuam sab nraud, uas yog ib qho ua rau cov txheej tsis ua haujlwm hauv cov kav dej faus.

•Zoo heev Adhesion thiab Cathodic Disbondment Resistance: FBE thiab nplaum txheej ua kom muaj kev ruaj khov rau cov hlau thiab siab tiv thaiv kev tsis sib haum xeeb, txawm tias muaj kev tiv thaiv cathodic tam sim no.

• Lub neej ua haujlwm ntev: Qhov zoo ntawm 3LPE coatings pab txhawb lub neej kev pab cuam ntawm 30-50 xyoo lossis ntau dua, txo nqi kho thiab hloov cov nqi.

•Versatility: Haum rau ntau yam ntawm kev khiav hauj lwm kub thiab ib puag ncig tej yam kev mob, los ntawm nruab nrab mus rau heev txhoj puab heev av.
