Kedu ihe kpatara ị na-ahọrọ flanges igwe anaghị agba nchara 304 butt

Ka anyị jiri eziokwu malite:
A na-ejikarị ọkpọkọ igwe anaghị agba nchara Austenitic n'ọtụtụ ebe na-emebi emebi. Otú ọ dị, ọ bụrụ na ị kpachara anya, ị ga-ahụ na n'ime akwụkwọ imewe nke ụfọdụ nkeji, ọ bụrụhaala na DN≤40, ihe niile ụdị ihe na-isi nakweere. N'ime akwụkwọ nhazi nke nkeji ndị ọzọ, ọkpọkọ igwe anaghị agba nchara, n'agbanyeghị otú caliber dị ntakịrị, ha na-ejikwa ọkpọkọ ọkpọkọ butt-welded kama iji akwa tube.
Dị ka okwu na-aga: iji hụ na ịgbado ọkụ àgwà nke obere-caliber ọkpọkọ ma zere ịgbado ọkụ penetration n'oge nnukwu ugbu ịgbado ọkụ, njikọ soket na-ejikarị kama butt ịgbado ọkụ njikọ. Yabụ, gịnị kpatara na nkeji ndị ọzọ nke igwe anaghị agba nchara obere ọkpọkọ caliber anaghị ebu iberibe intubation? Nke a na-agụnye nsogbu: crevice corrosion.
Ka anyị kwuo maka ihe bụ crevice corrosion?
Mgbe enwere oghere (n'ozuzu 0.025-0.1mm) n'elu ihe ndị na-emepụta ígwè n'ihi ihe ndị si mba ọzọ ma ọ bụ ihe nhazi, ọ na-esiri ike ịkwaga ihe na-emebi emebi na oghere ahụ, nke na-eduga na corrosion metal, nke a na-akpọ gap corrosion. Corrosion Crevice na-aghọkarị mkpali nke corrosion ndị ọzọ (dị ka pitting corrosion, stress corrosion), ya mere oru ngo na-agbalịsi ike izere omume nke crevice corrosion. Ekwesịrị izere ịdị adị nke mgbawa na nhazi nke usoro pipeline maka ọkara nke na-adịkarị mfe ịgbawa corrosion.

Ọ bụ n'ihi na enwere oghere na njikọ oghere, ya mere ụfọdụ nkeji iji zere mmebi nke ọdịiche ahụ, maka ịdị adị nke corrosion nke igwe anaghị agba nchara, obere obere caliber pipeline na-ejikarị njikọ ịgbado ọkụ, njikwa usoro ịgbado ọkụ iji hụ na ịdị mma, zere ịdị adị. ojiji nke intubation.
304 bụ igwe anaghị agba nchara zuru ụwa ọnụ, a na-eji ya eme ihe n'ịmepụta akụrụngwa na akụkụ chọrọ arụmọrụ zuru oke (nguzogide corrosion na formability).
304 igwe anaghị agba nchara bụ akara igwe anaghị agba nchara emepụtara dịka ụkpụrụ ASTM siri dị na United States. 304 bụ nke China 0Cr19Ni9 (0Cr18Ni9) igwe anaghị agba nchara. 304 nwere 19% chromium na 9% nickel.
304 bụ igwe anaghị agba nchara, igwe anaghị agba nchara. Ejiri ya na akụrụngwa mmepụta nri, akụrụngwa kemịkalụ xitong, ike nuklia, wdg.
