Kev txuag hluav taws xob HDPE Khoom Phab Ntsa Yeeb Nkab High-speed Extrusion Tshuab

(1) txhim khu kev qha kev sib txuas: polyethylene yeeb nkab tshuab txuas nrog electrothermal fusion, thiab lub zog ntawm kev sib koom ua ke yog siab dua li ntawm cov yeeb nkab lub cev.

(2) qhov zoo ntawm qhov kub thiab txias tsis kam: qhov kub thiab txias embrittlement ntawm polyethylene yog qhov tsawg heev, thiab nws tuaj yeem siv rau qhov kub thiab txias ntawm - 60-60 ℃. Thaum lub sij hawm tsim kho nyob rau hauv lub caij ntuj no, cov yeeb nkab embrittlement yuav tsis tshwm sim vim muaj kev cuam tshuam zoo ntawm cov khoom.

(3) zoo kev ntxhov siab tawg tsis kam: HDPE muaj qhov tsis tshua muaj siab, siab shear zog thiab zoo heev khawb tsis kam, thiab nws ib puag ncig kev ntxhov siab tawg kuj tseem zoo heev.

(4) Cov tshuaj zoo corrosion kuj: HDPE pipeline tuaj yeem tiv thaiv corrosion ntawm ntau yam tshuaj lom neeg, thiab cov tshuaj hauv av yuav tsis ua rau muaj kev puas tsuaj rau cov kav dej. Polyethylene yog ib qho hluav taws xob insulator, yog li nws yuav tsis rot, xeb lossis electrochemical corrosion; Tsis tas li ntawd, nws tsis txhawb kev loj hlob ntawm algae, kab mob los yog fungi.

(5) kev laus tsis kam thiab kev ua haujlwm ntev: cov kav dej polyethylene uas muaj 2-2.5% 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.

(6) zoo hnav tsis kam: kev sib piv ntawm kev hnav tsis kam ntawm HDPE yeeb nkab thiab steel yeeb nkab qhia tau hais tias hnav tsis kam ntawm HDPE yeeb nkab yog 4 npaug ntawm cov yeeb nkab steel. Hauv kev thauj mus los ntawm av nkos, piv nrog cov yeeb nkab steel, HDPE yeeb nkab muaj kev hnav zoo dua, uas txhais tau hais tias HDPE yeeb nkab muaj kev pab cuam lub neej ntev thiab kev lag luam zoo dua.

(7) zoo yoog raws: qhov yooj yim ntawm HDPE pipeline ua rau nws yooj yim rau khoov. Hauv engineering, obstacles tuaj yeem hla dhau los ntawm kev hloov cov raj xa dej. Feem ntau, qhov hloov pauv ntawm cov raj xa dej tuaj yeem txo qhov kev siv cov yeeb nkab fittings thiab txo tus nqi installation.

(8) me me ntws tsis kam: HDPE yeeb nkab muaj du sab hauv, thiab nws cov Manning coefficient yog 0.009. Qhov kev ua tau zoo thiab cov yam ntxwv tsis zoo ua kom ntseeg tau tias HDPE cov kav dej muaj peev xwm thauj mus los ntau dua li cov kav dej ib txwm muaj, thiab tseem txo qis kev poob siab thiab dej xa hluav taws xob ntawm cov kav dej.

(9) yooj yim tuav: HDPE yeeb nkab yog sib dua li cov yeeb nkab, galvanized yeeb nkab thiab steel yeeb nkab. Nws yog ib qho yooj yim los lis thiab nruab, thiab qis zog thiab cov khoom siv yuav tsum tau txhais tau hais tias tus nqi installation ntawm qhov project yog txo qis heev.

(10) ntau yam kev tsim kho tshiab: HDPE pipeline muaj ntau yam kev siv thev naus laus zis. Ntxiv nrog rau txoj kev khawb ib txwm, nws kuj tseem tuaj yeem tsim los ntawm ntau yam tshiab uas tsis yog excavation technologies, xws li yeeb nkab jacking, directional drilling, hauv ob sab phlu, yeeb nkab tawg, thiab lwm yam., uas yog ib qho kev xaiv zoo rau qee qhov chaw uas excavation tsis yog. tso cai.
