Dab tsi yog siv hauv kev tsim cov malleable steel yeeb nkab fittings cam khwb cia los ntawm malleable steel?

Lub tes tsho cua sov ntawm malleable steel yeeb nkab fittings tuaj yeem ua rau hauv ib qho qhib riser lossis tsaus riser. Thaum tsim cov qauv, cov qauv xoob xoob sib npaug sib npaug ntawm lub voj voog sab nraud ntawm lub tes tsho cua sov yuav tsum tau ua, thiab cov kab noj hniav ntawm lub taub hau ntawm lub tsho cua sov yuav tsum tau txais tom qab kev tsim khoom tiav. Thaum kaw lub thawv, muab lub tes tsho cua sov ntawm qhov qhib riser rau hauv kab noj hniav los ntawm sab saum toj ntawm lub thawv sab saud. Tom qab pouring, ib txheej ntawm insulating tus neeg saib xyuas yuav tsum tau sprinkled nyob rau hauv cov kua hlau nto ntawm lub riser los tiv thaiv saum npoo ntawm lub taub hau los ntawm overheated.

Thaum tsim cov qauv, lub taub hau tseem ceeb nrog ib txoj kab uas hla sib npaug ntawm cov riser tsaus yog ua rau ntawm tus qauv. Thaum molding, lub tes tsho cua sov muab tso rau ntawm lub taub hau tseem ceeb thiab kos rau hauv pwm. Tom qab tau txais qhov kov, lub hau npog cua sov tsuas yog nyob twj ywm hauv cov pwm pwm, tawm hauv lub qhov cua ntawm riser rau ntawm cov pwm casting.

Kev noj zaub mov zoo ntawm qhov tsaus riser ntawm lub tes tsho cua sov yog siab dua li qhov qhib riser ntawm lub tes tsho cua sov, yog li qhov tsaus ntuj riser ntawm lub tes tsho cua sov yog siv ntau dua li qhov qhib qab los ntawm lub tes tsho cua sov hauv kev tsim khoom.

Muaj ib lub nplhaib xuab zeb nrog qhov siab ntawm 10-40mm ntawm lub hauv paus ntawm qhov tsaus nti riser ntawm lub tes tsho cua sov ntawm lub malleable steel yeeb nkab haum (qhov txwv sab saud yog coj mus rau qhov loj dua cua sov riser, thiab qhov kev txwv qis yog coj rau qhov me me), thiab cov xuab zeb nplhaib yog tsim los ntawm cov xuab zeb zoo tib yam molding thaum ua lub tes tsho. Yog, kuj tseem muaj cov xuab zeb nplhaib zoo ib yam li cov hauv paus hniav ntawm qhov tsaus nti riser ntawm lub tes tsho cua sov ntawm lub hauv paus ntawm lub tes tsho cua sov, tab sis nws tsis yog pounded thaum ua lub tes tsho cua sov ntawm lub riser ci, tab sis yog pounded thaum ua rau sab nrauv. pwm. Lub luag haujlwm ntawm lub nplhaib xuab zeb yog tiv thaiv lub tes tsho cua sov los ntawm kev sib cuag ncaj qha rau cov casting, ua rau muaj qhov tsis xws luag xws li xuab zeb nplaum thiab cov pa roj carbon monoxide, thiab ua kom yooj yim ntxuav. Cov tshuaj tiv thaiv combustion ntawm lub tes tsho cua sov ua rau cov roj ntau ntau, yog li lub tes tsho cua sov yuav tsum tau ua nrog cov qhov tso pa tawm.

Qhov tseeb, qhov ntxhib thiab dub yog nyob rau hauv ob txoj kev naming. Qhov ntxeev ntawm qhov khoob yog cov khoom tiav. Cov xim dub yog qhov txawv ntawm qhov dawb (galvanized qhov chaw). Nws tsuas yog hais tias qhov saum npoo ntawm malleable steel yeeb nkab fittings tsis galvanized zoo li cov khoom dub, yog li nws yooj yim rau cov tib neeg ua yuam kev. Malleable steel yeeb nkab blanks xa mus rau cov khoom cam khwb cia uas tsis tau machined. Ntawm lawv, machining kev suav nrog lub qhov ncauj tiaj tus, shaping, galvanizing, threading thiab hauv ob sab phlu yas, thiab lwm yam. Cov blanks ntawm malleable steel yeeb nkab fittings muab faib ua raw blanks thiab siav blanks. Ntawm lawv, cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.

Cov xim dub ntawm malleable steel yeeb nkab fittings xa mus rau qhov tiav malleable steel yeeb nkab fittings yam tsis muaj kev kho deg. Nws cov yam ntxwv yog tias nws tau ua tiav los ntawm threading thiab lwm yam machining, tab sis nws nto tsis tau galvanized thiab anti-xeb, yog li nws yog hu ua dub qhov chaw. Qhov opposite yog cov galvanized yeeb nkab fittings, hu ua dawb qhov chaw, kuj hu ua galvanized qhov chaw. Cov khoom dawb tau muab faib ua cov khoom dawb tiav thiab cov khoom dawb ntxhib. Dawb blanks yog cov yeeb nkab fittings uas tau galvanized tab sis tsis threaded. Raws li qhov sib txawv ntawm galvanizing, nws tau muab faib ua qhov kub-dip thiab txias-dip qhov chaw, nrog rau qhov hu ua ci qhov chaw (uas yog, qhov saum npoo yog dipped nyob rau hauv cov hmoov hmoov xim thiab ces qhuav hauv qhov cub).
