Qhov Zoo
Siab lub zog thiab zoo heev neeg kho tshuab cov khoom
Nws khav theeb lub zog tensile lub zog (485-620 mpa
Haum rau nruab nrab thiab kub-kub ib puag ncig nrog kev ruaj khov zoo kawg
Tsim tshwj xeeb rau nruab nrab thiab kev kub ntxhov siab, nws tuaj yeem tswj hwm cov qauv kev ruaj ntseg thiab cov neeg kho tshuab txawm tias nyob hauv ib puag ncig 350 degree. Nws yog tsim tshwj xeeb rau cov khoom siv uas ua haujlwm hauv nruab nrab thiab kub rau cov dej sov thiab chav tsim hluav taws xob tshwm sim los ntawm kev ua haujlwm tsis zoo.
Zoo heev Weldability thiab ua cov khoom haum
Nws tau tshaj nrog cov vuam vuam xws li arc vuam thiab submerged arc vuam. Thaum siv nrog cov hluav taws xob tsawg-hydrogen) (piv txwv li, E7018), nws tuaj yeem ua tiav cov khoom siv zoo, txo cov nqi vuam thiab cov nqi.
Nws txhawb ntau txoj kev ua nrog rau kev txiav laser txiav, nplaim txiav, thiab cov thwj cim kev sib sau. Cov phiaj tuab tuaj yeem siv tau zoo zam cov kab nrib pleb tom qab kev kho mob uantej, yoog raws kev tsim khoom lag luam ntawm cov khoom siv nyuaj.
Nruj me ntsis tswj tau kom muaj kev ntseeg tau
Nws yuav tsum tshaj 100% ultrasonic qhov khuam nrhiav kom tau (raws li asme sa20 / sa20m qauv) ua ntej tawm hauv lub Hoobkas kom paub tseeb tias tsis muaj qhov tsis xws sab hauv. Qhov no zam kev nyab xeeb kev nyab xeeb tshwm sim los ntawm cov khoom uas tsis muaj txiaj ntsig los ntawm cov khoom uas tsis muaj peev xwm los ntawm cov khoom siv thiab ua raws li cov khoom muaj kev pheej hmoo zoo xws li cov khoom lag luam siab.
