409 410 ʻO ka paʻakikī kiʻekiʻe ʻO Martensitic stainless steel i hoʻopili ʻia i nā paipu wili ʻia i ka ʻoihana.
Koho mea maka
E koho i ka pepa kila martensitic paʻakikī kiʻekiʻe no ka ASTM A268 / A268M a i ʻole EN 10297-2.
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, pono paha ka mālama ʻana i ka hopena paʻa a me ka mālama ʻana i ka wā kahiko e hoʻihoʻi i nā waiwai mechanical a me ke kūpaʻa corrosion 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.
I ke koho ʻana a me ka hoʻohana ʻana i nā paipu kiʻekiʻe martensite stainless steel welded, pono e noʻonoʻo ʻia ko lākou wahi noi kikoʻī a me nā koi hana e hōʻoia i ka hana a me ka palekana o nā mea. I ka manawa like, e hahai ʻia nā kūlana kūpono a me nā kikoʻī e hōʻoia i ka maikaʻi o nā paipu welded.
