ASTM A192 Size Range
Kunze Diameter: 12.7-177.8mm [1/2-7 mukati.]
Ukobvu hudiki hwemadziro: 2.2-25.4mm [0.085 -1in.]
Machubhu ane mamwe mativi anogona kupihwa, chero machubhu akadaro achienderana nezvimwe zvese zvinodiwa zveichi chirevo.
Kugadzira
Machubhu achave asina musono uye achipisa kana kutonhora akashanda sekutsanangurwa Kugadziriswa.
ASTM A192 inzira mbiri huru dzekugadzira pombi yesimbi isina musono: inotonhora inodhonzwa uye inopisa yakakungurutswa.
Kupisa Kurapa
Kupisa kunorapwa pa1200 ℉ [650 ℃] kana pamusoro mushure mekupedzisira kutonhora kwekusveta ndima.

Kuwedzera Processing
Paunenge uchitenga uye uchishandisa ASTM A192 pombi, iyo yekupedzisira-yekushandisa nharaunda uye chaiyo mushandisi zvinodiwa zvingada kumwe kugadzirisa:
Paint kana Coating
Rustproof pendi kana mamwe machira ekudzivirira anogona kuiswa pamusoro.Aya machira anopa imwe dziviriro kubva mukuora, kunyanya kana iyo boiler chubhu yakafumurwa nehunyoro.
Anti-corrosion mishonga
Pamusoro pekupenda, mamwe marapirwo anorwisa-corrosion akadai se galvanizing, aluminizing, kana kupfekwa nezvimwe zvinorwisa-corrosion zvinogona kushandiswa kubatsira kuwedzera kusimba kwechubhu munzvimbo dzakaoma.
Kupisa Kurapa
Kunyangwe ASTM A192 ichitsanangura zvinodikanwa pakugadzira uye kuyedzwa kwepombi, mune mamwe maapplication ekuwedzera kupisa kupisa (semuenzaniso, normalizing, annealing) inogona kudikanwa kuti uwane chaiwo ma mechanic properties kana kuvandudza microstructure yepombi.
Yemukati uye Yekunze Surface Inopedza
Nzvimbo dzemukati nekunze dzemachubhu ebhailer zvingangoda kugadzikwa pasi, kukwenenzverwa, kana kucheneswa kuitira kuvandudza kuyerera kwemvura kana kuchena.
Pedzisa kugadzira
Zvichienderana nezvinodiwa pakuisirwa nekubatanidza, migumo yemachubhu ebhailer angangoda kuvezwa, chamfered, kana neimwe nzira kugadzirwa kufambisa kuiswa.
Kuwedzera Kuongorora
Kuona kuti machubhu anosangana neASTM A192 uye zvinodiwa nevatengi, kumwe kuongorora kunogona kuitwa.Semuenzaniso, ultrasonic test, X-ray yekuongorora, nezvimwe.
