3PE anticorrosion steel yeeb nkab feem ntau yog siv nyob rau hauv txhua yam ntawm engineering pipeline tej yaam num. Txij li nws yog carbon steel yeeb nkab yog dav siv nyob rau hauv pipeline systems rau thauj roj, natural gas, dej thiab lwm yam kua.

Nyob rau hauv cov ntaub ntawv no, lawv yuav tsum muaj siab tsis kam mus tshuaj corrosion, noo noo, teeb meem ib puag ncig thiab lwm yam corrosive zog. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua kom cov raj xa dej txheej nrog corrosion kuj.

Yog li peb feem ntau siv 3PE, 2PE, FBE los tiv thaiv corrosion thiab lwm txoj hauv kev los tiv thaiv corrosion. Feem ntau siv 3LPE txheej, suav nrog 3 txheej ntawm polyethylene. 3PE anti-corrosion steel yeeb nkab muaj qhov cuam tshuam zoo, ua haujlwm tsis zoo, cuam tshuam tsis kam, acid tsis kam, ua haujlwm zoo thiab ua haujlwm ntev.

3PE anti-corrosion steel yeeb nkab yog dab tsi?

3PE, peb kuj hu ua 3LPE. 3PE anticorrosion steel yeeb nkab yog txheej txheej txheej rau carbon steel yeeb nkab. Txawm hais tias nws yog welded steel yeeb nkab, stainless hlau yeeb nkab lossis hlau alloy steel yeeb nkab, nickel alloy yeeb nkab lossis seamless steel yeeb nkab nrog CRA cladding lossis hauv ob sab phlu yeeb nkab, tag nrho cov ntawm lawv tuaj yeem coated nrog 3PE ntawm cov yeeb nkab.

Sib nrug los ntawm 2PE, 2PP thiab 3PP, 3PE txheej yog feem ntau siv txoj kev tiv thaiv corrosion. Kev tsim cov txheej txheem ntawm cov txheej txheem no zoo sib xws tab sis cov khoom siv raw sib txawv. Cov txheej txheem tsim khoom ntawm 3LPE no yooj yim heev. Thiab nws muaj zoo corrosion kuj thiab zoo heev los tiv thaiv corrosion nyhuv.

Txoj kev pheej yig tiv thaiv corrosion no feem ntau lees txais thoob ntiaj teb. 3PE tuaj yeem txhim kho cov khoom siv kho tshuab ntawm cov raj xa dej, kev ua haujlwm siab, tsis muaj dej, hnav-tiv taus thiab tiv thaiv kev laus. Nws tuaj yeem tiv thaiv cov raj xa dej los ntawm kev poob cua sov uas tsuas yog tso nyiaj rau 1/4 ntawm cov kav dej.

Kev siv 3PE anticorrosion steel yeeb nkab

Peb siv 3LPE anticorrosion steel yeeb nkab nyob rau hauv qhov kev ncua deb kis tau tus mob ntawm natural gas, crude roj thiab refined roj. Nws kuj tseem siv rau hauv cov kav dej hauv nroog, cov tso tsheb hlau luam thiab cov trench piping systems.Qhov tseem ceeb ntawm 3PE yog los tiv thaiv cov kav dej siv hauv kev lag luam hluav taws xob thiab kev sib txuas lus nrog rau cov kav dej.

Txheej ntawm 3PE los tiv thaiv corrosion steel yeeb nkab

Raws li lub npe qhia, 3PE txheej muaj 3 txheej.

Thawj txheej ntawm 3PE txheej:

Fusion bonded epoxy resin, thickness >100μm.(Thickness of FBE coating >100μm)

Ob txheej ntawm 3PE txheej:

Adhesive txheej. Nws txuas cov epoxy resin thiab PE txheej. (Thickness ntawm ob txheej yog 170 txog 250 μm.)

Thib 3 PE txheej:

PE txheej. Lub thickness yog 2.5mm mus rau 3.7mm. Nws yog polyethylene, uas muaj qhov zoo ntawm kev tiv thaiv dej, hluav taws xob thiab kev puas tsuaj. Qhov no yog ib txheej tseem ceeb heev.

Los ntawm txheej txheej ntawm 3PE, koj yuav pom tias 3PE anti-corrosion steel yeeb nkab muaj qhov zoo ntawm FBE thiab PE. Nws yog ntau thiab ntau siv dav hauv cov kav dej hauv av rau kev thauj mus los ntawm dej, roj thiab roj. Qhov no kuj txhais tau tias yog lub Hoobkas muaj 3PE coated steel yeeb nkab tsim khoom, lawv tuaj yeem tsim FBE coated yeeb nkab.

Cov khoom ntawm 3PE anti-corrosion steel yeeb nkab:

Siab sealing. Nws txuag lub zog, txo tus nqi thiab tiv thaiv ib puag ncig hauv kev ua haujlwm ntev.

Siab corrosion kuj. Lub builder tsuas yog ceev ceev. Lub neej ua haujlwm yog mus txog 30 ~ 50 xyoo.

Zoo corrosion kuj thiab cuam tshuam tsis kam, tsis tshua muaj dej nqus. PE ntawm qhov kub thiab txias (tsawg dua 0.01%).

Siab zog epoxy resin. PE absorber thiab kub yaj nplaum yooj yim, thiab lwm yam nrog kev ntseeg siab corrosion.

Nta thiab qhov zoo ntawm 3PE anti-corrosion steel yeeb nkab

Lub neej ua haujlwm ntev

3PE anti-corrosion steel yeeb nkab tuaj yeem txuas ntxiv rau ntau tshaj 50 xyoo. Qhov no yog vim 3PE txheej muaj kev ruaj ntseg zoo thiab tiv thaiv kev laus nyob rau hauv ib txwm ua haujlwm kub thiab siab.

Corrosion tsis kam ua haujlwm

Cov ntsiab lus ntawm PE structural stability yog siab. Yog li ntawd, peb tuaj yeem siv nws los tiv thaiv corrosion ntawm natural gas, LPG, man-made gas thiab lwm yam tshuaj. Thiab nws tsis xav tau cov khoom siv tiv thaiv corrosion thib ob. Cov tshuaj av siv 3LPE txheej yuav tsis muaj kev cuam tshuam rau cov yeeb nkab steel.

Yooj yim

3PE txheej yog cov khoom siv tau yooj yim uas tawg tom qab txuas ntxiv 5 zaug. Yooj yim khoov yam tsis muaj kev puas tsuaj.3PE coated steel yeeb nkab tuaj yeem hla los txo tus nqi installation.

Superior Impact thiab Vibration Resistance

Ib qho tseem ceeb ntawm 3LPE txheej yog tias 3pe tsis tawg ntawm qhov kub thiab txias. Qhov ntsuas kub muaj kev nyab xeeb nyob rau thaj tsam ntawm -60 degree ~ 60 degree . Yog li nws tuaj yeem hloov mus rau qhov chaw kaw hauv lub caij ntuj no.3PE yeeb nkab muaj cov khoom zoo, yog li nws tsis yooj yim rau tawg.

Kev ntsuam xyuas qhia tau hais tias kev puas tsuaj ntawm PE yeeb nkab yog 4 npaug ntawm cov yeeb nkab hlau liab qab. Tshwj xeeb tshaj yog rau conveying slurry, PE coated yeeb nkab muaj kev puas tsuaj zoo dua piv rau cov xim hlau yeeb nkab.3PE muaj ib tug du nto nrog mating yam ntawm 0.009.

3PE coated steel kav muaj qhov zoo nkauj sab hauv thiab cov khoom tsis yog lo, ua rau muaj peev xwm hloov dej ntau dua thiab txo qhov poob siab thaum thauj.

Cov dej tsis zoo permeability ntawm 3PE coated steel yeeb nkab txhim kho nws qhov kev sib cais ntawm cov dej hiav txwv piv rau lwm cov txheej txheem txheej thiab FBE coated kav.

Cov khoom siv PE yog cov khoom siv ntsuab, tsis muaj tshuaj lom thiab tsis muaj mob. Nws tsis ntxiv hnyav hlau stabilizers rau cov txheej txheem ntawm 3LPE coated steel kav. 3PE tuaj yeem rov ua dua tshiab thiab yog li tsis ua phem rau ib puag ncig.

Cov khoom no ua rau cov kav dej PE haum rau cov nplaim taws thiab tawg.

Kev ruaj ntseg thiab txhim khu kev qha kev sib txuas

3PE coated steel yeeb nkab feem ntau yog siv cov cua sov fusion thiab cov cua sov fusion kev sib txuas kom lub interface thiab cov yeeb nkab txuas nrog tag nrho. Tsis muaj dej thiab roj to.

Lub teeb, yooj yim txav, yooj yim los tsim

Qhov hnyav ntawm 3PE yog lub teeb heev. Nws tsuas yog tso nyiaj rau 1/8 ntawm qhov hnyav ntawm cov yeeb nkab steel. nws yooj yim txav thiab khoov. Nws yooj yim txav, khoov, thiab nws cov txheej txheem vuam yog ceev thiab yooj yim. Nws muaj cov txiaj ntsig kev lag luam pom tseeb hauv tag nrho qhov project.
