3 LPE Coated Yeeb Nkab

3LPE Coated yeeb nkab yog dab tsi?

3LPE coated yeeb nkab inlcudes 3 txheej txheej, thawj FBE txheej, nruab nrab yog nplaum txheej, sab nraum polyethylene txheej. 3PE txheej yeeb nkab yog lwm yam khoom tshiab tsim los ntawm FBE txheej txheej txij li xyoo 1980s, uas muaj cov nplaum nplaum thiab PE (polyethylene) txheej. 3PE tuaj yeem ntxiv dag zog rau lub raj xa dej kom muaj zog, muaj zog hluav taws xob, tsis muaj dej, hnav, tiv thaiv kev laus.
Nws tuaj yeem tiv thaiv cov yeeb nkab los ntawm qhov kub poob uas tsuas yog account rau 1/4 ntawm cov yeeb nkab.

3LPE coated yeeb nkab muaj 3 txheej:

Rau thawj txheej yog fusion bonded epoxy, uas thickness yog loj dua 100μm. (FBE> 100μm)

Qhov thib ob txheej yog nplaum, uas cov nyhuv yog khi epoxy thiab PE txheej. Qhov siab: 170 ~ 250μm

Cov txheej thib peb yog PE txheej uas yog polyethylene muaj qhov zoo rau kev tiv thaiv dej, hluav taws xob tiv thaiv thiab tiv thaiv kev puas tsuaj. (φ{1}}φ1020 hli)
Yog li ntawd, 3PE txheej yeeb nkab ua ke nrog qhov zoo ntawm FBE thiab PE. Qhov twg ntau thiab ntau tau siv dav hauv faus pipeline thauj dej, roj thiab roj.

Nyob rau hauv cov ntaub ntawv tsim khoom, 3PE txheej steel yeeb nkab manufacturers lawv tuaj yeem ua FBE txheej yeeb nkab.

3PE / 3LPE coated yeeb nkab nta thiab qhov zoo

3LPE coated yeeb nkab feem ntau yog siv rau sab nrauv txheej rau corrosion tiv thaiv sab nraud ib puag ncig, FBE yog rau cov yeeb nkab sab hauv txheej los tiv thaiv cov kua dej corrosion, siv rau kev lag luam tshuaj los yog kev sib kis ntawm cov dej haus.

Lub neej ntev

3LPE coated steel yeeb nkab muaj kev ruaj ntseg zoo thiab kev tiv thaiv kev laus ua haujlwm raws li qhov kub thiab txias ua haujlwm, yog li nws lub neej ntev tuaj yeem ntev dua 50 xyoo.

Corrosion kuj

Vim PE cov qauv kev ruaj ntseg yog siab heev, nws yog resistant rau corrosion ntawm natural gas, liquefied petroleum gas, dag roj thiab lwm yam tshuaj, tsis xav tau lwm yam khoom siv los tiv thaiv corrosion. Cov tshuaj ntawm cov av tsis tsim kev cuam tshuam rau cov yeeb nkab.

Yooj yim

3PE / 3LPE yog ib yam khoom muag thiab hloov tau yooj yim, nws tuaj yeem ua kom ntev li 5 zaug tom qab tawg. Thaum nws yooj yim khoov thiab tsis muaj kev puas tsuaj. 3LPE / 3PE txheej steel yeeb nkab tuaj yeem hla cov khoom thiab txiav cov nqi ntawm kev teeb tsa.

Zoo tiv thaiv kev cuam tshuam thiab av qeeg

Polyethylene tsis tawg nyob rau hauv qis kub, muaj rau, nws muaj kev nyab xeeb siv nyob rau hauv qhov kub thiab txias ntawm qhov ntau ntawm -60 degree ~ 60 degree . Yog li nws tuaj yeem hloov kho mus rau hauv cov raj xa dej, Ua haujlwm rau lub caij ntuj no. Vim muaj kev cuam tshuam zoo, PE kav dej yuav tsis yooj yim tawg.

Zoo heev hnav tsis kam

Kev sim qhia tau hais tias PE yeeb nkab hnav tsis kam yog 4 zaug ntawm cov yeeb nkab. tshwj xeeb tshaj yog nyob rau thaj tsam ntawm kev thauj av nkos. Piv rau cov yeeb nkab varnished, PE coated yeeb nkab muaj kev hnav zoo dua.

3PE/3LPE muaj du nto, nws manning coefficient yog 0.009. Vim hais tias ntawm du sab hauv nto thiab tsis-sticking kev ua tau zoo, 3PE / 3LPE coated steel yeeb nkab qhia tau hais tias muaj peev xwm ntau dua rau kev thauj mus los, thiab txo qhov poob siab thiab thauj dej. Cov yam ntxwv qis dej permeation muab kev txhim kho kev sib cais ntawm cov dej hiav txwv piv rau lwm cov txheej txheem txheej thiab FBE yeeb nkab.

Kev tiv thaiv ib puag ncig zoo ua haujlwm

3LPE coated steel pipelines nyob rau hauv kev tsim cov txheej txheem yuav tsis ntxiv hnyav hlau stabilizer, PE khoom tsis muaj tshuaj lom thiab raug mob, yog ib yam ntawm cov khoom ntsuab, thiab nws tus kheej muaj peev xwm rov ua dua yuav tsis ua paug rau ib puag ncig.

Cov hluav taws xob zoo heev, kev ua haujlwm zoo li qub.

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

Kev nyab xeeb thiab txhim khu kev qha kev sib txuas

3LPE / 3PE txheej steel yeeb nkab feem ntau yog siv kub yaj thiab fused kev twb kev txuas, kom lub interface thiab pipeline txuas tag nrho. Tsis muaj dej thiab roj to.

Lub teeb, yooj yim txav, thiab yooj yim rau kev tsim kho

3LPE cov khaubncaws sab nraud povtseg tsuas yog 1/8 rau cov yeeb nkab steel, yooj yim txav, khoov, vuam txheej txheem yog yooj yim thiab ceev, tus nqi qis rau tag nrho cov haujlwm, cov txiaj ntsig kev lag luam pom tseeb.

Txij li thaum 3LPE thiab FBE txheej tuaj yeem ua rau lub neej ntev ntawm tib cov yeeb nkab steel los ntawm ob peb xyoos mus rau ntau xyoo, nws yuav tsum muaj ntau tshaj li ntau xyoo dhau los ntawm cov kav dej.
