Nws yog siv hauv tshav pob qhib tshuab rau tshuaj lom neeg, thee, thiab roj av kev lag luam nrog lub siab tsis kam rau kev cuam tshuam nrog kev xeb, qhov kub tsis taus rau cov khoom siv hauv tsev, thiab qhov chaw nrog kev kho cua sov nyuaj.

Siv ntau yam:

1. Cov raj cua sov ua kom sov

Cov yam ntxwv ntawm kev ua haujlwm: du sab hauv phab ntsa ntawm cov yeeb nkab, tsis tshua muaj dej tsis kam, yaig thiab kev daws teeb meem kev kho mob, cov yam ntxwv ua tau thiab xeb tsis kam ntawm cov weld hlaws thiab cov substrate yog qhov zoo ib yam, thiab kev sib sib zog nqus ua tau zoo heev.

2.thin-walled stainless hlau raj

Cov yam ntxwv ntawm kev ua tau zoo: kev pab lub neej ntev; tus nqi poob qis thiab dej qo tawg dej; cov dej huv zoo, tsis muaj cov khoom siv yuav ua rau dej ntws mus rau hauv dej; sab hauv phab ntsa ntawm cov yeeb nkab tsis txhuam, du, tsis muaj dej tsis kam; kev ua haujlwm siab, kev pab cuam lub neej ntev ntawm 100 xyoo, tsis muaj txij nkawm, tsis tshua muaj nqi; tuaj yeem tiv cov dej siab ntawm qhov dej ntws txog 30m / s; du raj tso pw, zoo nkauj tsos.

3. Lub raj xa khoom noj khoom haus tu

Cov yam ntxwv ntawm kev ua haujlwm: sab hauv sab saum npoo roughness Ra yog ntau dua 0.2, phab ntsa dai qhov seem yog me me, yooj yim ntxuav, tiv thaiv kab mob kev loj hlob, electrolytic polishing muaj cov nyhuv passivation, thiab sab hauv phab ntsa muaj kev tiv thaiv zoo.

4. kua dej tsis xeb hlau stainless raj

Ua tib zoo tsim stainless hlau sab hauv tsev welded yeeb nkab, dav siv hauv cov khoom siv mis nyuj, npias, dej haus tshuaj, tshuaj lom neeg, roj ntsha, tshuaj pleev ib ce, tshuaj zoo ua piv rau cov hlau tsis huv huv steel yeeb, nws qhov chaw ua tiav thiab du ntsa sab hauv, steel phaj yooj yim dua, kev tiv thaiv dav , teeb tsa ua ke phab ntsa ntau dua, qib siab dua, tsis muaj qhov pitting, zoo zoo.
