ʻO nā paipu kila kila ASTM A249 304L 316L
ʻO ka paipu hao ʻili ʻole ASTM A249 304L 316L,
Kina Hale Hana a me ka Paipu Seamless,
ʻO nā mea a pau e pili ana i ka SS 304 Heat Exchanger Tubes
No ka mea, ʻo Stainless Steel ka mea maʻalahi loa i loaʻa i ka mākeke i hoʻohana ʻia i ka hana ʻana i nā huahana like ʻole.ʻO ka heleʻana o ka chromium i ke kila e hoʻonui i kona waiwai kū'ē a me kona ikaika i nā kūlana nui.ʻO nā paipu hoʻololi wela i hana ʻia me SS304 e hōʻike ana i nā hiʻohiʻona maikaʻi e like me nā māka SS ʻē aʻe.He kūlana maikaʻi loa ka papa a me nā hiʻohiʻona hoʻoheheʻe ʻana i mea nui i ka hana ʻana i nā paipu kila kila.Loaʻa i ka papa 304 ka pale ʻana i ka oxidation maikaʻi loa, ke kū ʻana o ka lua i ka chloride, ke kūpaʻa ʻana o ka crevice corrosion, ke koʻikoʻi ke kūʻē i ka corrosion māwae a me ka ikaika maikaʻi i ka wela a me ke kaomi.
Ma waho aʻe o kēia, hōʻike ka papa i nā waiwai mechanical maikaʻi loa e like me ka ikaika tensile kiʻekiʻe;ʻO nā waiwai kolo pōkole ʻoi aku ka maikaʻi, ka elongation maikaʻi, a me ka hoʻomaikaʻi ʻana i ka ikaika hua kekahi o nā ʻano i loaʻa.No laila, ma muli o kēia mau hiʻohiʻona i ʻōlelo ʻia i loko o ka papa ua lilo ia i mea koho maikaʻi loa no nā ʻoihana e hana i ka maikaʻi maikaʻi Stainless Steel S30400 Heat Exchanger Tubes.
Pehea ka piha ʻana o nā paipu hoʻololi?
Hoʻohana ka ʻoihana i nā ʻano hana hoʻopihapiha kūpono i mea e pale aku ai i nā pilikia maikaʻi.Hoʻopili ʻia nā paipu hoʻololi wela o ka papa SS i loko o ka pahu lāʻau nui, nā pahu a i ʻole nā pallets i ʻole ka fumigation a me nā ʻano haumia ʻē aʻe.Eia kekahi, hāʻawi ʻia nā paipu i nā mea kūʻai aku me nā palapala hoʻouna kūpono.
