PE Linear yas yeeb nkab
Kev Ua Haujlwm: Kev ua haujlwm kub: -25 degree ~ ntxiv rau 75 degree (qhov siab tshaj plaws ua haujlwm kub ntawm polyethylene hloov: 105 degree)
Nruab nrab ua hauj lwm siab: zoo siab yog 2.5MPa thiab tsis zoo siab yog 75 KPa
Corrosion kuj: nonoxidation acid (xws li hydrochloric acid, hydrochloric acid, dilute sulfuric acid, hydrofluoric acid), dilute nitric acid, alkali thiab ntsev tov, tab sis tsis tiv taus corrosion ntawm concentrated nitric acid, concentrated sulfuric acid thiab lwm yam muaj zog oxidants. Zoo corrosion kuj rau cov kuab tshuaj organic thiab ntawm qhov kub thiab txias.
Daim ntawv thov: haum rau kev thauj mus los ntawm cov kua nruab nrab, tsim nyog rau kev thauj mus los ntawm cov dej hauv tsev thiab haus dej txias thiab dej txias, dej xa mus, tsis cuam tshuam rau cov dej zoo, raws li cov kev xav tau ntawm kev noj qab haus huv, siab hnav tsis kam. density polyethylene yeeb nkab tuaj yeem siv dav rau kev thauj mus los ntawm cov kua slurry xws li thee, ore. Dav siv nyob rau hauv petrochemical khoom hluav taws xob dej dej ib puag ncig tiv thaiv thiab lwm yam lag luam.
⑴ Txhim khu kev sib txuas: polyethylene yeeb nkab system txuas nrog hluav taws xob thermal melting hom, thiab lub zog ntawm kev sib koom ua ke yog siab dua li ntawm cov yeeb nkab lub cev.
⑵ Cov kub tsis zoo cuam tshuam tsis zoo: qhov kub thiab txias ntawm polyethylene yog qhov qis heev, uas tuaj yeem siv tau zoo nyob rau hauv qhov kub thiab txias ntawm -60-60 degree . Nyob rau hauv lub caij ntuj no kev tsim kho, vim muaj kev cuam tshuam zoo ntawm cov khoom, cov yeeb nkab brittle cracking yuav tsis tshwm sim.
⑶ Zoo kev ntxhov siab tawg tsis kam: HDPE muaj qhov sib txawv tsis tshua muaj siab, siab shear zog thiab zoo khawb tsis kam, ib puag ncig kev ntxhov siab tawg kuj tseem zoo heev.
⑷ Cov tshuaj tiv thaiv corrosion zoo: HDPE kav dej tuaj yeem tiv taus corrosion ntawm ntau cov tshuaj lom neeg, thiab cov tshuaj muaj nyob hauv cov av yuav tsis ua rau muaj kev puas tsuaj ntawm cov kav dej. Polyethylene yog ib qho hluav taws xob insulator, uas tsis rot, xeb lossis electrochemical corrosion; nws tsis txhawb kev loj hlob ntawm algae, kab mob los yog fungi.
⑸ Kev laus ua haujlwm, lub neej ua haujlwm ntev: cov yeeb nkab polyethylene uas muaj 2-2.5 feem pua ntawm cov khoom sib xws ntawm cov pa roj carbon dub tuaj yeem khaws cia rau sab nraum zoov lossis siv rau 50 xyoo, tsis muaj kev puas tsuaj vim hluav taws xob ultraviolet.
⑹ Zoo hnav tsis kam: qhov sib piv hnav tsis kam ntawm HDPE yeeb nkab thiab cov yeeb nkab steel qhia tau hais tias qhov hnav tsis kam ntawm HDPE yeeb nkab yog 4 npaug ntawm cov yeeb nkab steel. 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.
⑺ Kev yooj yim zoo: qhov yooj yim ntawm HDPE yeeb nkab ua rau nws yooj yim rau khoov, engineering tuaj yeem hloov cov kev taw qhia ntawm cov kav dej nyob ib puag ncig cov teeb meem, feem ntau, qhov yooj yim ntawm cov kav dej yuav txo tau cov yeeb nkab fittings thiab txo tus nqi installation.
⑻ Cov dej ntws me me: HDPE yeeb nkab muaj lub ntsej muag du, 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 kav dej muaj peev xwm ntau dua li cov kav dej ib txwm muaj, tab sis kuj txo qis kev poob siab thiab kev siv hluav taws xob sib kis.
⑼ Kev tuav yooj yim: HDPE yeeb nkab yog sib dua li cov yeeb nkab, galvanized yeeb nkab thiab cov yeeb nkab steel, nws yog ib qho yooj yim rau nqa thiab nruab, cov neeg ua haujlwm qis thiab cov khoom yuav tsum tau ua, uas txhais tau hais tias tus nqi installation ntawm qhov project yog txo qis heev.
⑽ Ntau hom kev tsim kho tshiab: HDPE kav dej muaj ntau yam kev tsim kho tshuab, ntxiv rau siv tau cov kev cai ntawm kev khawb av, kuj tuaj yeem siv ntau yam tshiab trenchless technology xws li yeeb nkab jacking, directional drilling, hauv ob sab phlu, tawg raj. kev tsim kho, qhov no rau qee qhov tsis tso cai rau kev khawb av, yog qhov kev xaiv nkaus xwb, yog li HDPE pipeline thov ntau dua.
1, softness: vim PE-RT kuj yog mos. Yog li ntawd, tsis muaj cov cuab yeej tshwj xeeb xav tau thaum lub sijhawm tsim kho, yog li tus nqi tsim kho kuj tseem tsawg. 2, thermal conductivity: cov yeeb nkab siv rau hauv pem teb cua sov yuav tsum muaj cov thermal conductivity zoo. PE-RT muaj cov thermal conductivity zoo, thiab nws cov thermal conductivity yog ob zaug ntawm PP-R thiab PP-B kav. Zoo meej rau pem teb cua sov.3. Kev kub siab ua haujlwm: PE-RT tuaj yeem tiv taus qhov kub siab kom ncav cuag 90 degree, thaum PEX tsuas tuaj yeem ncav cuag 65 degree .4, qhov kub thiab txias tsis kam thiab cuam tshuam tsis kam: PE- -RT tsis tshua muaj kev cuam tshuam kev ua haujlwm zoo zoo. Hauv kev tsim kho lub caij ntuj no, cov yeeb nkab tsis yooj yim rau kev cuam tshuam thiab tawg, uas ua rau kom yooj yim ntawm kev tsim kho.5, kev tiv thaiv ib puag ncig: PE-RT thiab PP-R tuaj yeem rov ua dua tshiab, tsis muaj kuab paug ib puag ncig. Thiab PEX tsis tuaj yeem rov ua dua
