Dab tsi yog qhov zoo ntawm HDPE pipeline systems?

Cov kav dej HDPE yog cov khoom hloov ntawm cov kav dej ib txwm siv thiab cov kav dej polyvinyl chloride haus. Qhov zoo nws muaj yog raws li nram no:
⑴ Txhim khu kev sib txuas: Polyethylene pipeline systems txuas nrog hluav taws xob cua sov fusion, thiab lub zog ntawm cov pob qij txha yog siab dua lub zog ntawm lub raj xa dej.
⑵ Qhov zoo ntawm qhov kub thiab txias tsis kam: Polyethylene muaj qhov kub thiab txias tsis tshua muaj siab embrittlement kub thiab tuaj yeem siv nyab xeeb hauv qhov kub thiab txias ntawm -60-60 degree. Thaum lub caij ntuj no kev tsim kho, vim muaj kev cuam tshuam zoo ntawm cov ntaub ntawv, yuav tsis muaj qhov tshwm sim ntawm cov yeeb nkab tawg.
⑶ Kev ua haujlwm zoo rau kev ntxhov siab tawg: HDPE muaj qhov tsis tshua muaj siab, siab shear zog, zoo heev khawb tsis kam, thiab zoo heev tiv thaiv ib puag ncig kev ntxhov siab tawg.
(4) Cov tshuaj tiv thaiv corrosion zoo: HDPE kav tuaj yeem tiv taus corrosion ntawm ntau yam tshuaj lom neeg, thiab cov tshuaj lom neeg muaj nyob hauv av yuav tsis ua rau muaj kev puas tsuaj rau cov kav dej. Polyethylene yog ib qho insulator rau hluav taws xob, yog li nws yuav tsis raug kev puas tsuaj, xeb, lossis electrochemical corrosion; Ntxiv mus, nws tsis txhawb kev loj hlob ntawm algae, kab mob, los yog fungi.
(5) Kev laus ua haujlwm thiab kev ua haujlwm ntev: cov kav dej polyethylene uas muaj 2-2.5 feem pua ​​​​ntawm cov pa roj carbon dub sib npaug tuaj yeem khaws cia sab nraum zoov lossis siv rau 50 xyoo yam tsis muaj kev puas tsuaj los ntawm hluav taws xob ultraviolet.
Kev hnav tsis zoo: Kev sib piv ntawm kev hnav tsis kam ntawm HDPE kav thiab cov kav hlau hlau qhia tau hais tias hnav tsis kam ntawm HDPE kav yog plaub npaug ntawm cov kav hlau. Hauv kev thauj mus los ntawm av nkos, HDPE kav dej muaj qhov hnav zoo dua piv rau cov kav hlau, uas txhais tau hais tias HDPE kav dej muaj kev pab cuam ntev dua thiab kev lag luam zoo dua.
(7) Kev ua tau zoo: Kev hloov pauv ntawm cov kav dej HDPE ua rau lawv yooj yim khoov. Hauv engineering, obstacles tuaj yeem hla dhau los ntawm kev hloov cov raj xa dej. Feem ntau, qhov yooj yim ntawm cov kav dej tuaj yeem txo cov yeeb nkab fittings thiab txo cov nqi installation.
Tsis tshua muaj dej ntws tsis kam: HDPE kav dej muaj qhov sib luag sab hauv thiab Manning coefficient ntawm 0.009. Qhov kev ua tau zoo thiab cov khoom tsis muaj nplaum ua kom ntseeg tau tias HDPE kav dej muaj peev xwm ntau dua li cov kav dej ib txwm muaj, thaum tseem txo qis kev poob siab thiab dej xa hluav taws xob siv ntawm cov kav dej.
(9) Kev tuav yooj yim: HDPE kav yog sib zog dua li cov kav dej ua vaj tse, cov kav dej galvanized, thiab cov kav hlau steel, ua rau lawv yooj yim rau kev tswj thiab nruab. Kev ua haujlwm qis dua thiab cov khoom siv yuav tsum tau txhais tau hais tias yuav txo qis hauv kev teeb tsa tus nqi ntawm qhov project.
(10) Ntau yam kev tsim kho tshiab: HDPE kav dej muaj ntau yam kev tsim kho tshuab. Ntxiv nrog rau txoj kev khawb ib txwm siv, nws kuj tseem tuaj yeem siv ntau yam tshiab uas tsis yog excavation technologies, xws li yeeb nkab jacking, directional drilling, hauv ob sab phlu, yeeb nkab splitting, thiab lwm yam. Qhov no tsuas yog kev xaiv rau qee qhov chaw uas tsis pub excavation, yog li ntawd. HDPE pipeline yog siv ntau dua.
