Pipe Seamless High Pressure, Nā Hana Hana
ʻO ke kiʻekiʻe puʻupuʻu seamless paipu，He ʻano o ka seamless tube.ʻO keʻano o ka hanaʻana heʻano like ia me ka paipu liʻiliʻi, akā aia nā koi koʻikoʻi ma keʻano o ke kila i hoʻohanaʻia no ka hanaʻana i ka paipu kila.E like me ka hoʻohana ʻana i ka mahana, ua māhele ʻia i ʻelua ʻano o ka pahu paila maʻamau a me ka pahu paila kiʻekiʻe.
① ʻO ke kiʻekiʻe puʻuwai seamless paipu ， Aia ka mahana hana ma lalo o 450 ℃, hana nui ʻia ka paipu home no.10 a me No.20 carbon bonded steel hot rolled pipe a i ʻole ka paipu huki anu.
② ʻO ke kiʻekiʻe puʻuwai seamless paipu，Ke hoʻohana ʻia, aia ka paipu ma lalo o ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe.Ma lalo o ka hana o ke kinoea flue wela kiʻekiʻe a me ka mahu wai, e hiki mai ka oxidation a me ka corrosion.Pono ka paipu kila e loaʻa ka ikaika lōʻihi kiʻekiʻe, ke kūpaʻa ʻana i ka corrosion oxidation kiʻekiʻe a me ke kūpaʻa microstructure maikaʻi.
