Cold Hardening uye Hydrogen Embrittlement yeASTM A179 Seamless Tubes

Mukugadzira maitiro eastm a179inotonhora inokweva seamless simbi pombi, kune kutonhora kuoma uye hydrogen embrittlement phenomenon, iyo inokonzerwa nechando inoswededzwa seamless chubhu inoputika chikonzero chikuru.

Ongororo yechiitiko chekuputika kweastm a179 inotonhora inodhonzwa isina musono pombi idiki dhayamita yepombi isina musono pombi kuburikidza nedhirowa inofa yekutonhora ichiita kutonhora kuumba, nzira yekugadzira inowanzo kunyura, kunhonga, kudhirowa.Inotonhora-inodhonzwa diki dhayamita isina musono simbi pombi mukudhirowa, dzimwe nguva kubva pakutanga kusvika kumagumo seyakafanana neye cracker bamboo crack phenomenon, tinodaidza chiitiko ichi chiri kuputika.

Zvikonzero zvekuputika ndezvekuti:

Mhedzisiro yekuomesa basa, iyo pombi yesimbi inoburitsa huwandu hukuru hwemapurasitiki ekudhirowa panguva inotonhora yekudhirowa, zvichikonzera kukanganisa kwakakosha kwelatisi, iyo inowedzera simba relatisi uye inowedzera simba remukati resimbi, zvichikonzera kusaenzana kwemukati kushushikana kwesimbi uye kusara kwakasara kushushikana. .Izvi zvichawedzera kuoma kwesimbi, kuoma kwakaderera.Iyo yakakwirira kuoma kwesimbi, kunowedzera kwasara kushushikana kwemukati panguva yekutonhora kudhirowa, zvakanyanya kujeka basa rinoomesa chiitiko.Kana kushushikana kwasara kwasvika pahumwe kukosha, simbi inobvarura pamwe neimwe yezviyo interface, kuumbwa kwepaipi yesimbi yakapfava ichitsemuka.

Mhedzisiro yehydrogen embrittlement, mukuita kudonha neasidhi, sulfuric asidhi uye iron zvinobata kune precipitate haidrojeni.Hydrogen inopinda musimbi iri muchimiro chemaatomu kana kuti ayoni kuita chigadziko chakasimba.Mhedzisiro yehaidhirojeni pamagetsi esimbi inofanana neiyo hydrogen embrittlement.
