He aha nā mea hana o nā paipu kila kuhili ʻole ʻenehana

ʻO nā paipu kila kila ʻeleʻele i hoʻopaʻa ʻia i ka paia he maikaʻi ka wela a me ka pale ʻana i ka corrosion, no laila nui nā huahana ʻoihana e hoʻohana i kēia ʻano paipu. ʻOiai mākou e launa pinepine me nā paipu kila kila, ʻokoʻa loa nā paipu ʻoihana mai nā paipu a mākou e launa pinepine ai. ʻO ke kaʻina hana ʻenehana he ʻano paʻakikī, no laila e makaʻala loa ke koho ʻana i nā mea.

ʻO Austenitic 310s stainless steel he maikaʻi ke kūpaʻa oxidation a me ke kūpaʻa corrosion. Ma muli o ke kiʻekiʻe o ka pākēneka o ka chromium a me ka nickel, he kūpaʻa kona kolo a hiki ke hana mau i nā wela kiʻekiʻe, e hōʻike ana i ke kūpaʻa kiʻekiʻe kiʻekiʻe. Ma lalo o ke kulou like a me ka ikaika torsional, he māmā a kūpono i nā ʻōnaehana pipeline wela i ka ʻoihana kemika. He kūpono hoʻi ke kila pale wela no ka hana ʻana i nā ʻāpana umu like ʻole, me ka mahana hana a hiki i 1200 ℃ a me ka mahana hoʻohana mau a hiki i 1150 ℃.

ʻO ka paipu 304L he ʻano like ʻole o ke kalapona haʻahaʻa 304, ʻike ʻia hoʻi he kila kalapona ultra-low, i hoʻohana ʻia i nā kūlana e koi ʻia ai ka wili. ʻO ka haʻahaʻa kalapona e hoʻemi ana i ka ua o ka carbide ma ka wahi wela kokoke i ka weld, hiki ke alakaʻi i ka corrosion intergranular (welding corrosion) o ke kila kila ma kekahi mau kaiapuni, e like me nā pipeline ʻoihana.

Hiki ke hoʻohana ʻia nā paipu kila kuhili ʻole 316 me ka ʻiʻo kalapona ma lalo o 0.03 i nā noi kahi hiki ʻole ke hoʻopili ʻia ke kuʻi ʻana a koi ʻia ke kūpaʻa kiʻekiʻe. ʻOi aku ka maikaʻi o ka hana holoʻokoʻa o kēia kila ma mua o 310 a me 304 stainless steel, a loaʻa iā ia ke kūpaʻa corrosion kiʻekiʻe kiʻekiʻe inā ʻoi aku ka nui o ka sulfuric acid ma lalo o 15% a ma luna o 85%. ʻO nā noi maʻamau e pili ana i nā mea hoʻololi wela, nā mea pena kala, nā mea hoʻomohala kiʻiʻoniʻoni, a me nā paipu pulp a me ka pepa.

Ua hoʻokomo kālā ʻo Shandong Kungang Metal Technology Co., Ltd. i ka nui o ke kālā e hoʻolauna i ka hana kiʻekiʻe a me ka nānā ʻana i nā lako hana e hōʻoia i ka maikaʻi o ka huahana, i mea e hōʻoia ai i ka nui o ka waihona, nā kikoʻī piha, nā kumukūʻai kūpono, a me ka inoa kiʻekiʻe. Hana nui ʻo Shandong Kungang Metal Technology Co., Ltd. i nā paipu kila kila, nā paipu kila ʻole, nā paipu welded, nā paipu PE a me nā huahana paipu ʻē aʻe. Manaʻo mākou e hoʻopili iā ʻoe!
