Raws li peb txhua tus paub tias muaj peb tus qauv ntawm cov kav hluav taws xob feem ntau siv hauv peb cov haujlwm, ASTM A795 cov kav dej tua hluav taws, UL852 cov kav dej tua hluav taws, thiab ASTM A53 cov kav hluav taws. Hnub no peb yuav tsom mus rau ASTM A795 cov kav dej tua hluav taws.
ASTM A795 Cov Lus Qhia Tshwj Xeebyog tus qauv specification rau dub thiab kub-dipped zinc-coated (galvanized) welded thiab seamless steel yeeb nkab rau kev siv tiv thaiv hluav taws. Qhov kev qhia tshwj xeeb no suav nrog cov phab ntsa thickness welded raj thiab seamless raj uas yuav tsum tau siv rau kev xa dej hauv kev tiv thaiv hluav taws. Tus qauv kuj tseem suav nrog kev sib koom ua ke ntawm cov yeeb nkab rau fittings thiab lwm yam khoom siv tiv thaiv hluav taws.
Daim ntawv thov kev tiv thaiv hluav taws yuav tsum muaj qib siabkev ntseeg siab thiab kev nyab xeeb.Thaum muaj hluav taws kub, cov txheej txheem tiv thaiv yuav tsum muaj peev xwm xa cov dej txaus los tua cov nplaim taws thiab tiv thaiv cov khoom thiab lub neej.ASTM A795 yog qhov feem ntau siv cov yeeb nkab tshwj xeeb rau kev tiv thaiv hluav taws vim nws lub zog, kev tiv thaiv corrosion, muaj, thiab cov nqi-zoo.
ASTM A795 cov kav dej feem ntau siv rau hauv ob qho tib si ntub thiab qhuav tiv thaiv hluav taws.Cov txheej txheem tiv thaiv hluav taws ntub dej siv dej ua tus neeg tua hluav taws thiab ua kom cov kav dej tas li. Ntawm qhov tod tes, kev tiv thaiv hluav taws qhuav, xws li thaum txhim kho nws hauv qhov chaw txias, muaj cua txias hauv cov kav dej, thiab cov dej tso tawm tsuas yog thaum lub kaw lus qhib. Cov kav dej uas siv rau hauv cov tshuab qhuav yuav tsum muaj kev tiv thaiv corrosion ntau dua vim huab cua sab hauv.
ASTM A795 tus qauv qhia txog ntau qhov ntev thiab cov khoom ntawm cov kav dej. Tnws cov kav dej tuaj yeem muaj phab ntsa tuab ntawm Sch.10 txog Sch.40, thiab tuaj yeem muaj qhov loj me los ntawm 1/2 ntiv mus rau 18 ntiv tes. Rau cov kav dej uas muaj txoj kab uas hla ntau dua ob ntiv tes, tus qauv xav kom lawv yuav tsum tau welded longitudinally los ntawm cov txheej txheem hluav taws xob tiv thaiv vuam (ERW). Rau tag nrho cov kav dej, tus qauv xav kom lawv kub-dipped galvanized tom qab tsim. Koj tuaj yeem kho koj tus kheejASTM A795 cov kav dej tua hluav taws hauv BAOLAI®- hluav taws kub kav chaw tsim tshuaj paus nyob rau hauv Suav teb.
Cov txheej txheem galvanization suav nrog kev siv zinc txheej rau cov yeeb nkab los tiv thaiv corrosion. Cov txheej txheem no ua kom cov kav dej muaj kev tiv thaiv los ntawm cov khoom corrosive uas yuav muaj nyob rau hauv cov hluav taws tua hluav taws, xws li cov kua qaub lossis lwm yam tshuaj. Lub zinc txheej kuj tiv thaiv cov yeeb nkab los ntawm corrosion los ntawm noo noo nyob rau hauv ib puag ncig.
ASTM A795 cov kav dej tuaj yeem siv tau rau ntau yam kev tiv thaiv hluav taws, suav nrog cov kav dej, cov tshuab tua hluav taws, thiab cov kav dej tua hluav taws. Standpipes yog cov kav dej ntsug ntsia tau rau hauv ib lub tsev los muab dej rau cov neeg tua hluav taws lub hoses thaum muaj hluav taws. Cov tshuab hluav taws xob hluav taws xob yog cov tshuab uas tuaj yeem ntes hluav taws thiab ua kom cov dej ntws tawm mus rau cov nplaim taws. Cov hluav taws kub hnyiab yog cov dej sab nraum zoov uas cov neeg tua hluav taws tuaj yeem txuas rau thaum muaj xwm txheej ceev.
Kev txhim kho cov kav dej ASTM A795 yuav tsum ua raws li cov chaw tsim khoom cov lus qhia, kev tuav kom zoo, thiab kev npaj cov yeeb nkab, thiab cov txheej txheem installation kom raug. Tus qauv qhia txog ntau txoj kev sib koom xws li threaded, grooved, thiab tsau flange koom nrog txoj kev. Threaded pob qij txha yuav tsum tau lub installation ntawm ib tug xov sealant los xyuas kom meej ib tug nruj haum thiab tiv thaiv los. Grooved pob qij txha siv cov khoom siv sib txuas uas yog tsim los ntawm ob lub grooved-kawg fittings uas qhwv lub gasket. Mechanical squeezed gasket tsim ib lub foob uas tiv thaiv kom tsis txhob xau.
Hauv kev xaus, ASTM A795 cov kav dej yog cov qauv kev lag luam rau kev tiv thaiv hluav taws vim lawv lub zog, kav ntev, thiab corrosion kuj. Cov kav dej yuav siv tau rau hauv ob qho tib si ntub thiab qhuav hluav taws tiv thaiv thiab muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab phab ntsa thicknesses. Kev txhim kho cov kav dej kom zoo yuav tsum ua raws li cov chaw tsim khoom cov lus qhia thiab cov txheej txheem tuav kom raug. Tus qauv qhia txog ntau txoj hauv kev sib koom ua ke uas tau tsim los tsim kom muaj lub foob foob. Kev siv cov kav dej ASTM A795 ua kom muaj kev nyab xeeb thiab txhim khu kev lag luam ntawm kev tiv thaiv hluav taws, uas muaj kev cuam tshuam ncaj qha rau kev tiv thaiv lub neej thiab khoom.
Yog tias koj tab tom nrhiav kev txhim khu kev qha hluav taws xob kav chaw tsim khoom / chaw muag khoom hauv Suav teb, Baolai Steel Pipe yog qhov kev xaiv rau koj xav tau.
