Cov qauv no suav nrog cov kav hlau welded uas tsim nyog rau kev tiv thaiv hluav taws. Nws qhia txog qhov yuav tsum tau ua rau cov kav hluav taws xob tiv thaiv-welded nrog qhov loj ntawm 1/2 nti mus rau 10 nti hauv nominal txoj kab uas hla.
2. ASTM A795 Cov Lus Qhia Tshwj Xeeb- Standard Specification rau Dub thiab Kub-dipped Zinc-Coated (Galvanized) Welded thiab Seamless Steel Yeeb Nkab rau kev siv tiv thaiv hluav taws
Cov txheej txheem no npog dub thiab kub-dipped galvanized welded thiab seamless steel kav uas tsim nyog rau kev siv tiv thaiv hluav taws. Nws kuj tseem qhia txog qhov yuav tsum tau ua rau cov kav hlau steel nrog qhov loj ntawm 1/2 nti mus rau 6 nti hauv nominal txoj kab uas hla.
3. TIAB SA 852- Txheem rau Hlau Sprinkler Yeeb Nkab rau Kev Tiv Thaiv Hluav Taws Xob
Cov txheej txheem no suav nrog cov kav dej hlau uas siv rau hauv kev tiv thaiv hluav taws. Nws suav nrog cov kev cai rau cov kav hlau siv hauv cov tshuab ntub dej thiab qhuav, nrog rau cov txheej txheem tshwj xeeb rau kev tsim, kev teeb tsa, thiab kev sim.
4. FM 1630 Nws- Kev pom zoo Standard rau Steel Yeeb Nkab rau Tsis Siv Neeg Hluav Taws Sprinkler Systems
Cov txheej txheem no teev cov kev cai rau cov kav dej steel uas siv hauv cov tshuab hluav taws xob tsis siv neeg. Nws suav nrog cov kev qhia tshwj xeeb rau kev tsim, kev teeb tsa, thiab kev sim ua haujlwm, nrog rau cov txheej txheem rau cov khoom zoo thiab kav ntev.
Hauv kev xaus, kev siv cov kav hlau uas ua tau raws li cov qauv thoob ntiaj teb yog qhov tseem ceeb rau kev ua kom muaj txiaj ntsig zoo thiab kev ntseeg siab ntawm kev tiv thaiv hluav taws. Los ntawm kev ua raws li cov qauv no, peb tuaj yeem pab tiv thaiv lub neej thiab khoom siv thaum muaj xwm txheej kub ntxhov.
Feem ntau siv steel qauv ntawm kev tua hluav taws cov kav dej:
1. UL Listed/FM pom zoo: Qhov no yog qhov kev lees paub ntau tshaj plaws thiab kev ntseeg siab rau cov kav dej tua hluav taws uas ua kom lawv ua tau raws li cov qauv kev nyab xeeb thiab kev ua haujlwm siab tshaj plaws. UL (Underwriters Laboratories) thiab FM (Factory Mutual) yog cov koom haum ywj pheej uas nruj me ntsis sim thiab lees paub cov kav hluav taws xob kom ntseeg tau tias lawv tuaj yeem tiv taus qhov kub thiab txias, siab, thiab lwm yam kev phom sij.
2. ASTM A795 Cov Lus Qhia Tshwj Xeeb: Cov qauv no qhia txog cov kev cai rau seamless thiab welded steel kav siv nyob rau hauv kev pab tiv thaiv hluav taws. Cov kav dej yuav tsum muaj cov phab ntsa tsis sib xws thiab yuav tsum tau coated nrog cov zinc txheej tiv thaiv kom tsis txhob xeb.
3. ASTM A53: Lwm tus qauv siv dav rau cov kav hlau siv hauv kev tiv thaiv hluav taws yog ASTM A53, uas npog ob qho tib si seamless thiab welded dub thiab kub-dipped galvanized steel kav. Cov kav dej no tsim nyog rau kev siv hluav taws kub nyhiab vim lawv qhov kev tiv thaiv zoo rau qhov kub thiab txias.
4. TS EN 10255: Cov txheej txheem European no qhia txog qhov yuav tsum tau ua rau cov kav dej nruab nrab thiab hnyav hlau siv hauv kev tiv thaiv hluav taws. Cov kav dej yuav tsum muaj cov phab ntsa tsis sib xws thiab yuav tsum tau galvanized los tiv thaiv xeb thiab xeb.
5. ISO 9001 Cov: Cov txheej txheem thoob ntiaj teb no tau teeb tsa cov txheej txheem rau kev tswj hwm kev ua haujlwm zoo ntawm cov chaw tsim khoom lossis cov chaw muag khoom ntawm cov kav dej tua hluav taws. Nws xyuas kom meej tias cov txheej txheem tsim ua raws li cov qauv thoob ntiaj teb thiab cov khoom kawg yog qhov zoo ib yam.
