Stainless Seamless Pipe
Kuoma :
Stainless simbi machubhu anowanzo shandiswa kuyera kuomarara kweBrinell, Rockwell uye Vickers.Kuomarara kweBrinell Pakati pezviyero zvepombi yesimbi isina tsvina, kuomarara kweBrinell ndiko kunonyanya kushandiswa, uye kuomarara kwezvinhu kunowanzo kuratidzwa nedhayamita indentation, izvo zviri zviviri intuitive uye zviri nyore.Zvisinei, hazvina kukodzera mapaipi esimbi esimbi yakaoma kana yakaonda.
Rockwell kuoma:
Iyo Stainless simbi chubhu Rockwell kuomarara bvunzo yakafanana neyeBrinell kuomarara bvunzo.Musiyano ndewekuti inoyera kudzika kweiyo indentation.Iyo Rockwell kuomarara bvunzo inzira inoshandiswa zvakanyanya iyo HRC inoshandiswa yechipiri chete kune Brinell kuomarara HB mune simbi pombi zviyero.Kuomarara kweRockwell kunogona kuiswa pakugadzwa kwezvinhu zvesimbi kubva pakupfava zvakanyanya kusvika pakuomarara kwazvo.Inotsiva nzira yeBrinell.Iyo iri nyore kupfuura nzira yeBrinell uye inogona kuverenga zvakananga kukosha kwekuoma kubva padhiya remuchina wekuoma.Nekudaro, nekuda kwediki indentation yayo, kukosha kwekuomarara hakuna kururama senzira yeBrinell.
Vickers kuoma
Iyo Stainless simbi chubhu Vickers kuomarara bvunzo zvakare indentation yekuyedza nzira yekuyera yakanyanya kutetepa simbi zvinhu uye pamusoro pehuremu hwekuoma.Iyo ine mabhenefiti makuru eBrinell neRockwell nzira, uye inokunda kukanganisa kwavo kwekutanga, asi haisi nyore senzira yeRockwell.Iyo Vickers nzira haiwanzo kushandiswa mune simbi pombi zviyero.
Muedzo wekuoma
Iyo chubhu yesimbi isina simbi ine dhayamita yemukati inosvika 6.0mm kana kudarika uye chubhu yesimbi isina tsvina ine mukobvu we13mm kana pasi.Inogona kunge iri W-B75 mhando yeVickers kuomarara tester.Iyo inokurumidza uye iri nyore kuyedza uye inokodzera kukurumidza uye isingaparadzi kuongororwa kwepombi dzesimbi isina tsvina.Machubhu esimbi asina simbi ane dhayamita yemukati inodarika 30 mm uye ukobvu hwemadziro hwakakura kupfuura 1.2 mm anoedzwa ne Rockwell hardness tester kuyedza HRB uye HRC kuoma.Machubhu esimbi asina simbi ane dhayamita yemukati inodarika 30 mm uye ukobvu hwemadziro husingasviki 1.2 mm anoedzwa nepamusoro Rockwell kuomarara tester kuyedza HRT kana HRN kuoma.Kune mapaipi esimbi isina tsvina ane dhayamita yemukati isingasviki 0 mm uye yakakura kupfuura 4.8 mm, kuomarara kweHR15T kunoedzwa neiyo yakakosha Rockwell kuomarara tester yemapombi.Kana iyo yemukati dhayamita yestainless simbi chubhu yakakura kupfuura 26 mm, kuoma kwemukati madziro echubhu kunogona zvakare kuongororwa neRo.
