2205 2507 Austenitic Ferritic Duplex Stainless Steel welded paipu （Ke kūʻē i ka chloride corrosion）
ʻO ka hana ʻana o 2205 a me 2507 duplex stainless steel welding paipu maʻamau e pili ana i kēia mau hana:
Hoʻomākaukau mea maka
E koho i ka pepa 2205 a i ʻole 2507 a i ʻole ka ʻili i kūpono no nā kūlana ASTM A790 / A789 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.
ʻO 2205 a me 2507 mau paipu wiliwili kila kila ʻelua he kūpono no nā noi ʻoihana he nui no ko lākou kūpaʻa ʻana i ka corrosion chloride. 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.
