Introduction to the technical introduction of stainless steel core corrosion pile wili.
Ke hoʻohana nei ka ʻenehana welding pile i ka wili e hoʻololi i ka ʻili o ka mea hana e hoʻokō i nā koi hana o ka mea hana i ka wā lawelawe. He kiʻekiʻe ka maikaʻi o ka hoʻoheheʻe ʻana o ke kaula, ʻoi aku ka maʻalahi o ke koena, liʻiliʻi loa ka splashing, nani ke ala kuʻi, a hiki ke hoʻokō i ka hoʻomau mau a paʻa no ka manawa lōʻihi, hiki ke hoʻomaikaʻi maikaʻi i ka hana hana.
JINGLEI puʻu kuʻihao kumu kuʻihao uwea
Hoʻohana maʻamau ʻo Hydrogenation reactor i ke kila CR-MO ma ke ʻano he substrate, a ʻo nā huahana uea kuʻikuʻi koʻikoʻi ʻo GFS-309L (pahu hoʻololi) a me GFS-347L (ke kūʻē corrosion) i hoʻohana nui ʻia no ka paia o loko a me ka ʻili o ka reactor.
GFS-309L+GFS-347L hui puʻu wiliwili
● kaʻina hana kuʻi pidium
KaʻAnuʻu ①:
ʻO ka mea mua, ua hoʻopaʻa ʻia ka GFS-309L ma luna o ka mea substrate e like me ka papa hoʻololi e pāʻani i kahi hana cushioning, hiki ke hōʻemi i ka hiki ke hoʻoheheʻe ʻia ma hope.
KaʻAnuʻu ②:
Hoʻohana ʻia ʻelua mau papa o GFS-347L o ka hui kuʻi ʻana ma ke ʻano he papa corrosion, a ʻo ka mānoanoa holoʻokoʻa o ka papa hoʻololi + papa corrosion ma kahi o 7 ~ 8mm.
KaʻAnuʻu ③:
Ma hope o ka welding thermal treatment (PWHT), pono ka mea kūʻai aku i ka 665 ° C × 12H+705 ℃ × 32h ma ke ʻano he laʻana.
KaʻAnuʻu ④:
Mīkini i ka mīkini wiliwili i ka mānoanoa i makemake ʻia.
