904L super austenitic kuhiliʻole kila wiliwili paipu

ʻO 904L he kila kila kila nui loa me ka pale ʻana i ka corrosion kiʻekiʻe loa, ʻoi aku hoʻi ma nā wahi i loaʻa nā ion chloride. Aia kēia mea i ka nickel kiʻekiʻe a me ka molybdenum maʻiʻo, a me ka liʻiliʻi o ke keleawe, e hāʻawi iā ia i ka maikaʻi o ka corrosion kū'ē i ka acidic, alkaline, a me ka paʻakai.

Kāhea iā mā˚ou

nā kikoʻī huahana

Koho mea maka

E hoʻohana i ka 904L ʻili kila kila a i ʻole ke kāʻei no nā kūlana ASTM A312 / A312M a i ʻole EN 10216-5.

Hoʻoheheʻe

E hana i ka pepa a i ʻole ka ʻili i ke ʻano paipu ma ka ʻōwili anu a i ʻole ke kaʻina huki anu.

wiliwili

Ke hoʻohana nei i ka TIG (tungsten pole argon arc welding) a i ʻole MIG (metal inert gas protective welding). Pono e hoʻomalu ponoʻia nā palena o ka welding i ka wā o ke kaʻina hana e hōʻoia i ka maikaʻi o ka weld.

Hoʻoponopono wela

Ma hope o ke kuʻi ʻana, koi ʻia ka lāʻau hoʻonā paʻa e hoʻihoʻi i ke kūpaʻa corrosion a me nā waiwai mechanical o ka mea.

Nānā a nānā

E hana i ka ho'āʻo nondestructive o ka paipu welded, e like me ka ultrasonic detection, radiographic detection, etc., e hōʻoia i ka weld me ka ʻole o nā hemahema. Hana ʻia ka hoʻāʻo ʻana i nā waiwai mechanical a me ka corrosion resistance i ka manawa like.

Lapaʻau ʻili

E like me ka pono, ka welded paipu ili lapaʻau, e like me pickling, passivation, etc., e hoʻomaikaʻi i ka corrosion kū'ē.

Hoʻopili a hāʻawi

Hoʻopili i nā paipu welded kūpono e hōʻoia i ka pōʻino ʻole i ka wā o ka lawe ʻana.

904L kuhiliʻole kila welded paipu mea maikaʻi i loko o ka nui o ka hanaʻoihana noi no ka maikaʻi loa corrosion kū'ē. I ke koho ʻana a me ka hoʻohana ʻana i kēia mau mea, e mālama pono i nā kūlana kūpono a me nā kikoʻī e hōʻoia i ka hana a me ka palekana o nā mea. I ka manawa like, no ka mea, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o 904L stainless steel, no laila i ke koho ʻana i nā mea, pono e noʻonoʻo ʻia e like me nā pono noi maoli a me nā pōmaikaʻi kumukūʻai.
