Cov kav dej uas tsim los ntawm kev sib txuas ntawm polyethylene muaj qhov zoo ntawm kev nkag siab siab, kev tiv thaiv corrosion, lub teeb yuag thiab zoo thaum tshav kub kub. Aluminium-yas composite yeeb nkab ua los ntawm cross-linked polyethylene muaj zog cua nruj thiab siab tiv thaiv blasting kev nyuaj siab. Nws muaj antistatic thiab shielding nyhuv.
PEX yeeb nkab piv nrog cov kav dej PVC thiab cov kav dej polyethylene zoo tib yam, cov kav dej sib txuas polyethylene tsis muaj cov yas, yuav tsis mildew thiab cov kab mob; tsis muaj cov khoom xyaw tsis zoo, ua tau raws li FDA cov qauv, thiab tuaj yeem siv rau cov kav dej haus; Thaum tshav kub kub kuj yog qhov zoo, qhov kub tsis kam ntawm cov khoom siv hluav taws xob zoo tib yam polyvinyl chloride thiab polyethylene yeeb nkab yog 60-75 degree, thiab qhov sib txuas ntawm cov yeeb nkab polyethylene yog 90 degree, qhov kub siab tshaj tam sim no tuaj yeem ncav cuag 185 degree, thiab tuaj yeem tiv taus qhov kub ntawm { {5}} degree; siv qhov kub thiab txias Qhov ntau yog dav, thiab nws tuaj yeem siv tau ntev hauv qhov xwm txheej ntawm -75-95 degree , thiab kev pabcuam lub neej ntev li 50 xyoo. High cross-linking degree, siab ceev, zoo siab tsis kam; Cov tshuaj zoo corrosion kuj, zoo heev ib puag ncig kev nyuaj siab cracking kuj, tuaj yeem siv los thauj ntau yam tshuaj txawm tias qhov kub siab dua Piv nrog rau cov ntaub ntawv kev ntxhov siab nrog cov kav dej nrawm, cov kav dej sib txuas polyethylene yog qhov hnyav, tsuas yog li 1/8 ntawm cov kav hlau. ; lawv muaj zoo corrosion kuj thiab hnav tsis kam. Tus nqi hnav tsawg dua 1/4 ntawm cov yeeb nkab steel, thiab lub neej kev pab cuam yog 2-6 npaug ntawm cov yeeb nkab steel; cov phab ntsa sab hauv yog du thiab cov kua dej tsis kam yog me me. Thaum cov yeeb nkab txoj kab uas hla yog tib yam, qhov kev xa khoom ntws loj dua li ntawm cov yeeb nkab hlau, thiab lub suab nrov qis dua; qhov kev sib kis tau zoo, qhov sib kis ntawm cov kua yog 30 feem pua -40 feem pua siab dua li cov kav hlau steel; Lub thermal conductivity tsawg dua li cov kav hlau, yog li nws cov thermal rwb thaiv tsev kev ua tau zoo heev. Thaum siv rau hauv lub tshuab cua sov, nws tsis xav tau kev txuag hluav taws xob, thiab cov cua sov poob yog me me; nws tuaj yeem khoov ntawm lub siab nyiam yam tsis muaj kab nrib pleb; nws muaj kev ua tau zoo ntawm cov hluav taws xob rwb thaiv tsev, kev yooj yim thiab yooj yim installation, thiab kev teeb tsa kev ua haujlwm tsawg dua li ib nrab ntawm cov kav hlau hlau, thiab tus nqi installation yog tsawg.
Vim muaj kev ua tau zoo ntawm pex yeeb nkab khoom. Nws yog kiag li tsis muaj tshuaj lom thiab tu cev, yog li nws tau raug suav tias yog ib tiam tshiab ntawm cov kav dej ntsuab, feem ntau yog siv hauv cov hauv qab no:
(1) Txhim kho cov dej txias thiab dej kub thiab cov kav dej haus;
(2) Cov tshuab cua txias thiab dej txias rau cov tsev;
pem teb cua sov system
(3) Cov cua sov hauv tsev;
(4) pem teb cua sov system;
(5) Cov kav dej ntawm lub tshuab rhaub dej hauv tsev;
(6) Cov kav dej rau cov kua dej xws li dej haus, cawv, thiab mis nyuj hauv kev lag luam khoom noj;
(7) Kev lag luam tshuaj lom neeg thiab roj av ua kua dej xa cov kav dej;
(8) Cov tub yees thiab cov kav dej kho dej.
