** 1. Yog alloy steel txawv dua li stainless hlau? **
Yog lawm, lawv txawv. Alloy Steel yog ib qeb dav dav ntawm cov hlau uas muaj lwm cov khoom ntxiv rau nws (zoo li boron) los txhim kho nws cov khoom siv tshuab xws li xws li lub zog, hardness, thiab hnav tsis kam. Stainless hlau yog qhov tseeb yog ib qho tshwj xeeb * hom * ntawm alloy steel. Dab tsi ua rau Stainless Hlau Txawv yog tias nws muaj tus nqi ntau heev ntawm chromium (tsawg kawg 10,5%), uas muab nws tus thawj coj thiab xeb corrosion thiab xeb tsis kam.
** 2. Dab tsi yog qhov sib txawv ntawm cov hlau uas tsis muaj hlau thiab hlau kav? **
Lo lus "steel kav hlau" feem ntau yog hais txog cov kav dej ua los ntawm cov roj carbon hlau. Tus yuam sij sib txawv yog nyob rau hauv lawv cov muaj pes tsawg leeg thiab cov khoom ntiag tug. Cov pa roj carbon cov kav hlau yog muaj zog thiab ruaj khov tab sis yuav xeb yooj yim thaum muaj dej noo thiab yuav tsum tau pleev xim los yog coated. Stainless hlau kav Ntim cov chromium, uas ua cov txheej txheem tiv thaiv uas ua rau lawv xeb muaj xeb thiab corrosion yam tsis muaj kev xav tau. Stainless hlau kuj tseem kim dua carbon hlau.
** 3. Dab tsi yog alloy steel yeeb nkab? **
Ib co yeeb nkab sib xyaw yog cov yeeb nkab tsim los ntawm cov hlau uas tau sib xyaw nrog lwm cov ntsiab lus (cov ntsiab lus ntawm cov roj carbon. Cov ntsiab lus no, xws li chromium, molybdenum, vanadium, lossis npib tsib xee, tau ntxiv kom muab cov yeeb nkab tshwj xeeb ua rau cov pa roj carbon. Cov yam ntxwv txhim kho muaj peev xwm suav nrog lub zog siab dua, muaj kev cuam tshuam tsis zoo, lossis txhim kho corrosion tsis kam piv rau cov qauv hlau hlau.
** 4. Peb Hom Hlau Hlau Yog Dab Tsi? **
Cov kav hlau hlau yog feem ntau categorized los ntawm lawv cov txheej txheem tsim kev tsim khoom. Peb lub ntsiab yog:
* ** SEAMLESS YEEB: ** Ua los ntawm cov khoom siv cylindrical steel bar (billet) uas yog rhuab thiab tho los ntawm lub chaw uas tsis muaj nqaws lossis Welds. Nws muaj zog dua thiab siv rau high-} qhov kev siv siab.
* ** Welded yeeb nkab: ** Ua los ntawm dov ib lub phaj steel lossis daim ntawv rau hauv ib lub cylindrical puab thiab tom qab ntawd vuam cov leeg ua ke. Nws yog ntau dua thiab tus nqi -} Siv tau ua tau zoo rau qhov tsawg rau nruab nrab cov ntawv thov.
* ** CAM KHAUB MOOK STEEFF: ** Ua niam txiv tau ua los ntawm poling hlau ua pwm. Nws yog cov nkig heev piv rau cov kav dej steel qub thiab yog feem ntau siv rau cov kab hauv nroog thiab dej phwj seb puas yog nws cov khoom lag luam zoo heev.
** 5. 5 tus kav dej tseem ceeb yog dab tsi? **
Tsib lub ntsiab ntawm cov kav dej, raws li lawv cov ntaub ntawv, feem ntau siv hauv kev tsim kho thiab kav dej yog:
* ** PVC / CPVC cov yeeb nkab: ** Lub teeb yuag, pheej yig, thiab corrosion {}} tiv taus yas tiv taus cov yeeb nkab. PVC yog siv rau dej txias thiab tso dej, thaum CPVC tuaj yeem tswj cov dej kub.
* ** COPPER HLAU: ** Zoo ruaj thiab tiv taus corrosion, feem ntau siv rau dej muab cov kab hauv tsev nyob hauv tsev. Nws yog ntseeg tau tab sis yuav yog kim.
* ** GALVANIZED STEEL YEE: ** Carbon Hlau Yeeb coated nrog zinc kom tiv thaiv xeb. Nws tau tshwm sim ib zaug rau cov dej tsis txaus tab sis yog tam sim no feem ntau hloov vim kev corrosion nyob rau hauv lub sijhawm.
* ** PEX YEEB: ** Ib lub taub yas yooj ywm uas yooj yim heev rau nruab los ntawm cov phab ntsa thiab ib ncig ntawm cov ces kaum. Nws tau dhau los ua tus txheej txheem niaj hnub no rau dej muab cov kab hauv kev tsim kho tshiab hauv tsev.
* ** Tus yeeb nkab hlau: ** Paub txog nws lub zog tshwj xeeb thiab corrosion tsis kam. Nws yog siv nyob rau hauv kev thov cov ntawv thov xws li cov nroj tsuag tshuaj chilical, ua zaub mov, thiab thaj chaw ntug hiav txwv, zoo li rau cov qauv stylish.
