PE yeeb nkab yog tam sim no dav siv nyob rau hauv ntau yam teb, vim hais tias nws cov khoom muaj cov yam ntxwv ntawm siab zog, siab kub tsis kam, corrosion kuj, non-toxicity, hnav tsis kam, thiab lwm yam., thiab ib tug ntxiv point, PE yeeb nkab yuav tsis xeb, muaj ntau yam kev lag luam yuav xaiv los siv Nws hloov cov kav dej ib txwm siv.
Qhov zoo ntawm PE yeeb nkab txiav txim siab nws daim ntawv thov dav. Piv nrog rau lwm cov kav dej, qhov zoo ntawm PE yeeb nkab yog qhov pom tseeb dua. Tom ntej no, Xiaoyuan yuav qhia rau koj txog kaum qhov zoo ntawm PE kav.
Ib qho ntawm qhov zoo ntawm PE yeeb nkab: kev sib txuas yog txhim khu kev qha
PE kav dej yog txuas nrog lub qhov (socket) kub-melt thiab kub-melt pob tw, thiab lub zog ntawm qhov sib koom ua ke yog siab;
Qhov thib ob zoo ntawm PE yeeb nkab: zoo cuam tshuam tsis kam ntawm qhov kub thiab txias
Qhov kub thiab txias catalytic kub ntawm cov yeeb nkab PE yog qhov qis heev, thiab nws tuaj yeem siv tau zoo nyob rau hauv qhov kub thiab txias. Thaum lub sij hawm tsim kho nyob rau hauv lub caij ntuj no, vim hais tias cov yeeb nkab PE muaj kev cuam tshuam zoo, cov yeeb nkab yuav tsis nkig.
Qhov thib peb zoo ntawm PE yeeb nkab: nws muaj zog tiv thaiv kev ntxhov siab tawg
PE yeeb nkab muaj kev khawb zoo heev, thiab nws qhov kev tiv thaiv rau ib puag ncig kev ntxhov siab tawg kuj tseem zoo heev.
Qhov thib plaub zoo ntawm PE yeeb nkab: zoo tshuaj corrosion kuj
PE cov kav dej tuaj yeem tiv taus qhov corrosion ntawm ntau yam tshuaj lom neeg, thiab cov tshuaj lom neeg hauv av yuav tsis degrade cov kav dej.
Qhov thib tsib qhov zoo ntawm PE yeeb nkab: kev laus ua haujlwm thiab kev ua haujlwm ntev
PE cov kav dej tuaj yeem khaws cia lossis siv sab nraum zoov rau 50 xyoo yam tsis muaj kev puas tsuaj los ntawm hluav taws xob ultraviolet.
Qhov thib rau qhov zoo ntawm PE yeeb nkab: zoo hnav tsis kam
Kev sib piv piv piv piv ntawm cov kav PE thiab cov kav hlau steel qhia tau hais tias qhov hnav tsis kam ntawm PE kav yog 4 npaug ntawm cov kav hlau. Hauv kev thauj mus los ntawm av nkos, PE kav dej muaj qhov hnav zoo dua li cov kav hlau steel, uas txhais tau hais tias cov kav dej PE Nws muaj kev pabcuam ntev dua thiab kev lag luam zoo dua.
Xya qhov zoo ntawm PE yeeb nkab: zoo dua yooj
Qhov yooj yim ntawm PE yeeb nkab ua rau nws yooj yim rau khoov, thiab hauv engineering, obstacles tuaj yeem hla los ntawm kev hloov cov kev taw qhia ntawm cov yeeb nkab. Feem ntau, qhov yooj yim ntawm PE yeeb nkab tuaj yeem txo cov yeeb nkab fittings thiab txo cov nqi installation.
Qhov thib yim zoo ntawm PE yeeb nkab: tiam ntawm cov dej ntws tsis kam yog me me
Cov yeeb nkab PE muaj lub ntsej muag du, thiab Manning coefficient ntawm cov yeeb nkab yog 0.009. Cov yeeb nkab du nto thiab cov khoom tsis muaj nplaum ua kom cov yeeb nkab muaj peev xwm ntau dua li cov kav dej ib txwm siv, thiab tib lub sijhawm
Nws kuj tseem txo cov kev poob siab ntawm cov raj xa dej thiab kev siv lub zog ntawm kev xa dej.
Cuaj qhov zoo ntawm PE yeeb nkab: yooj yim nqa
PE kav yog sib dua li cov kav dej ua vaj tse, cov kav dej galvanized thiab cov kav hlau steel. Nws yog ib qho yooj yim los nqa thiab nruab, thiab qis dua cov neeg ua haujlwm thiab cov cuab yeej siv tau txhais tau hais tias kev teeb tsa ntawm cov kav dej polyethylene txo qis heev.
Qhov thib kaum zoo ntawm PE yeeb nkab: ntau yam kev tsim kho
PE pipelines muaj ntau yam kev tsim kho tshuab. Ntxiv nrog rau txoj kev khawb ib txwm, muaj ntau yam tshiab uas tsis yog kev siv thev naus laus zis xws li cov yeeb nkab jacking, kev taw qhia drilling, hauv ob sab phlu, thiab cov kav dej sib cais kuj tuaj yeem siv rau kev tsim kho. Koj tuaj yeem xaiv Muaj ntau txoj kev tsim kho.
