1. Lub teeb yuag, kev thauj mus los yooj yim, kev tsim kho yooj yim:Cov yeeb nkab galvanized steel muaj lub zog tsim kho zoo, feem ntau xav tau cov cuab yeej siv los tsim kho xws li cranes; Qhov ceev ntawmPE yeeb nkab dejtsawg dua 1/8 ntawm cov yeeb nkab hlau, qhov ceev ntawm 0.935g /㎝3 galvanized steel yeeb nkab yog 7.88g /㎝3, lub zog tsim kho qis, thiab kev nce qib ntawm kev tsim kho yog ceev.
2.Kev tiv thaiv xebTom qab siv cov yeeb nkab galvanized ib ntus, cov txheej zinc tsuas yog raug rhuav tshem, ua rau cov yeeb nkab hlau xeb. Lub neej ua haujlwm ntawm cov yeeb nkab galvanized yog li 10 xyoo.PE yeeb nkab dejmuaj kev ruaj khov tshuaj zoo thiab tiv taus corrosion zoo heev. Kev sib deev, uas tsis tshua muaj tshuaj lom neeg nrog lwm cov ntsiab lus hauv dej, muaj lub neej ua haujlwm txog li 50 xyoo.
3.Ekev sib txuas yooj yim, kev teeb tsa yooj yim:Cov yeeb nkab galvanized yuav tsum tsis txhob vuam. Thaum lub flange vuam yuav tsum tau txuas nrog ib qho txuas, cov txheej galvanized puas tsuaj los ntawm kev vuam yuav tsum tau kho nrog kev tiv thaiv xeb; PE cov yeeb nkab xa dej siv cov kev sib txuas kub yaj. Nws yooj yim thiab ceev, txo qhov nyuaj ntawm kev tsim kho, thiab ua ke luv lub sijhawm tsim kho.
4. Lub neej ua haujlwm ntev: lub neej ua haujlwm ntawm cov yeeb nkab galvanized tsuas yog li 20-30 xyoo xwb, thaum PE yeeb nkab tuaj yeem tiv taus kev yaig ntawm ntau yam tshuaj lom neeg, thiab lub neej ua haujlwm txog li 50 xyoo nyob rau hauv cov xwm txheej ua haujlwm ib txwm muaj, uas yog raws li peb cov cai tam sim no ntawm lub tsev.
5.Gzoo tsis kam thiab yooj ywm: kev tsim cov yeeb nkab hlau galvanized muaj qhov yuav tsum tau ua ntau dua rau lub hauv paus yeeb nkab thiab kev hloov pauv tsis zoo; PE yeeb nkab yog cov yeeb nkab muaj zog siab, nws qhov ntev ntawm qhov tawg yog ntau dua 500%, uas yuav ua rau lub hauv paus tsis sib xws thiab kev hloov pauv. Nws hloov pauv tau yooj yim heev. Qhov yooj ywm ntawm lwm cov yeeb nkab PE tso cai rau P cov yeeb nkab loj txoj kab uas hla pe kom raug coiled, tshwj xeeb tshaj yog rau cov yeeb nkab me txoj kab uas hla pe, uas txo ntau qhov tau txais. Thaum lub sijhawm tsim kho, cov teeb meem tuaj yeem hla dhau hauv lub vojvoog zigzag ntawm qhov ntsuas tso cai ntawm cov yeeb nkab kom txo qhov nyuaj ntawm kev tsim kho.
6. Huab cua nruj zoo: Cov yeeb nkab loj uas muaj txoj kab uas hla loj txuas nrog los ntawm kev kub yaj, uas ua kom ntseeg tau tias qhov sib txuas ntawm cov khoom siv sib txuas thiab lub cev yeeb nkab nws tus kheej, thiab ua tiav kev sib koom ua ke ntawm qhov sib koom ua ke thiab yeeb nkab.
7.IPhab ntsa sab hauv du, cov dej ntws tau ntau, thiab kev siv zog ua haujlwm me me:Tus nqi roughness n ntawm PE raj tsuas yog 0.008 xwb. Tus nqi roughness ntawm cov yeeb nkab hlau galvanized tshiab yog 0.025, thiab tus nqi roughness yuav nce 510 zaug tom qab 20 xyoo ntawm kev ua haujlwm. PE dej xa vim tias cov yeeb nkab tsis yog corrosive, yog li nws qhov roughness tsis hloov pauv nrog lub sijhawm. Nyob rau hauv tib lub yeeb nkab txoj kab uas hla thiab tib lub siab dej, qhov kev poob tsis kam ntawm txoj kev tuaj yeem txo qis los ntawm 30%. Lub peev xwm hloov dej zoo dua li cov yeeb nkab hlau galvanized, thiab tuaj yeem kav ntev li 50 xyoo. Tsis muaj kev hloov pauv loj.
8. Kev saib xyuas yooj yim thiab kev saib xyuas qist: cov yeeb nkab PE loj loj yooj yim kho, tuaj yeem kho thiab teeb tsa yam tsis muaj dej cuam tshuam, thiab tsis xav tau cov khoom kim heev thiab qias neeg. Raws li kev paub txog kev tsim kho tiag tiag, tus nqi txij nkawm ntawm cov yeeb nkab PE tsuas yog 30% ntawm cov yeeb nkab hlau galvanized.
9. Kev hnav tsis kam zoo: Qhov kev hnav tsis kam ntawm PE dej yeeb nkab yog ntau dua 4 npaug ntawm cov yeeb nkab hlau galvanized.
10.Kev tiv thaiv kub tsawg zoo: qhov kub qis embrittlement kub ntawm PE dej yeeb nkab yog qis heev, thiab nws tuaj yeem siv tau zoo hauv qhov kub ntawm -20-40 ° C. Thaum lub caij ntuj no kev tsim kho, cov yeeb nkab brittleness yuav tsis tshwm sim vim yog qhov cuam tshuam zoo ntawm cov khoom siv.
CHUANGRONGyog ib lub tuam txhab sib koom ua lag luam thiab kev lag luam, tsim muaj xyoo 2005 uas tsom mus rau kev tsim cov kav dej HDPE, Fittings & Valves, PPR Pipes, Fittings & Valves, PP compression fittings & Valves, thiab muag cov tshuab vuam yas, cov cuab yeej yeeb nkab, cov cuab yeej kho yeeb nkab thiab lwm yam.
