Seamless Steel Hydraulic Lub tog raj kheej Honed yeeb nkab

Lus piav qhia luv luv:

Lub raj hydraulic yog lub tog raj kheej zoo li lub raj uas thaum txuas rau hydraulic systems, tso cai rau cov dej nkag mus rau hauv thiab ntawm cov khoom.Lub raj txheej txheem qhia qhov ntev rau qhov txias kos tiav thiab seamless precision steel raj.Txias cov txheej txheem muab lub raj nrog qhov ntev ntev, ua kom cov khoom muaj zog thiab txhim kho machinability.Yog li ntawd, hydraulic raj yog tsim nyob rau hauv kev ua tau zoo piping system daim ntawv thov.

Khoom Taw Qhia

Lawv feem ntau muaj qhov ntev li ntawm 6 meters ntev.Thaum txiav txim rau cov yeeb nkab, tus neeg siv yuav tsum ntsuas sab nraud thiab sab hauv txoj kab uas hla ntawm cov yeeb nkab.Yog tias phab ntsa tuab yog qhov tseem ceeb, cov yeeb nkab tuaj yeem raug txiav txim los ntawm OD thiab phab ntsa tuab lossis ID thiab phab ntsa tuab.

Raws li cov khoom siv zoo carbon steel, hydraulic steel yeeb nkab yog tsim nyog ntxiv nrog ib lossis ntau lub ntsiab lus alloying los txhim kho lub zog, toughness thiab hardenability ntawm hlau.

Hom hydraulic steel yeeb nkab feem ntau yog ua los ntawm quenching yuav tsum raug rau cov tshuaj tua hluav taws xob thiab kev kho cua sov ntawm qhov chaw.Piv nrog cov pa roj carbon zoo steel, cov qauv hlau muaj cov khoom siv zoo, thiab feem ntau yog dov rau hauv ib puag ncig, square, thiab tiaj tus hlau, uas yog ib qho tseem ceeb ntawm cov khoom siv los yog cov tshuab.Tab sis qhov hnav tsis kam thiab txiav tsis kam yog zoo dua li stainless hlau.

Muaj ob hom khoom qib, ST52.4 thiab ST37.4.ST52.2 yog lub siab tensile lub zog lub raj, txhais tau tias nws muaj kev tso cai ua haujlwm siab dua los ntawm kev txo cov raj phab ntsa tuab thiab ua rau lub cev hnyav dua.

Yuav ua li cas los tsim Hydraulic Tube?

Cov yeeb nkab nto tiav yog NBK, qhov twg cov yeeb nkab yog phosphated thiab normalized rau corrosion kuj.Oiled sab hauv thiab tawm.Cov txheej txheem normalizing tsim cov khoom siv hlau nyuaj.Thaum lub sij hawm normalizing, cov hlau yuav rhuab nyob rau hauv high kub thiab tom qab cua sov nws yuav lawm txias rau chav tsev kub los ntawm raug.Cov hlau uas tau dhau los ua cov txheej txheem no yooj yim dua rau kev tsim, nyuaj thiab ntau dua ductile.

Galvanized txheej muaj nyob ntawm kev thov.Galvanized hydraulic kav muaj zinc tiv thaiv txheej kom lawv kav ntev.Muaj ob hom galvanizing, kub-dip galvanizing thiab txias-dip galvanizing.

Muaj ob txoj hauv kev rau kev tsim cov raj, seamless lossis welded.Peb cov hlab hydraulic yog tsim nyob rau hauv ib tug seamless txheej txheem uas tsis muaj welds los yog seams raws li lawv yog rub los ntawm lub billet.

Kev tso cai ua haujlwm siab yog xam raws li DIN 2413 ntawm qhov kub thiab txias.Cov txiaj ntsig thiab tensile kev ntxhov siab yog siv los txiav txim siab qhov siab tshaj plaws uas tso cai rau kev khiav hauj lwm siab thiab phab ntsa thickness.Thaum cov yeeb nkab xa tuaj, qhov tseeb tawm los thiab tensile kev ntxhov siab qhov tseem ceeb raug txheeb xyuas los ntawm daim ntawv pov thawj tseeb ntawm cov khoom siv.Lub decompression

Coefficients ntawm txawv kub yog raws li nram no

° C	-40	120	150	175	200	250
° F	-40	248 ib	302 ib	347 ib	392 ib	482 ib
Rating Factor	0.90 ib	1.0	0.89 ib	0.89 ib	0.83 ua	N

Txhawm rau txiav txim siab qhov kev tso cai ua haujlwm siab ntawm qhov kub thiab txias, tom qab txiav txim siab qhov ntsuas kub, muab cov kev tso cai ua haujlwm siab rau sab nraud thiab thickness ntawm cov yeeb nkab hauv qab qhov ntsuas qhov ntsuas.
