Hana nui kā mākou hui i nā paipu BA&EP a me nā huahana paipu. Ke hoʻohana nei i ka ʻenehana kiʻekiʻe mai Iapana a me Korea, hiki iā mākou ke hāʻawi i nā huahana me ka pā o loko o Ra0.5, Ra0.25 a i ʻole. ʻO ka hana makahiki o 7 miliona mel, nā mea TP304L / 1.307, TP316L / 1.4404, a me nā huahana maʻamau. Hoʻohana ʻia kā mākou huahana i nā semiconductor, ka mana o ka lā, ka ikehu hydrogen, ke kiʻekiʻe o ka mālama ʻana i ka hydrogen, ka mining pōhaku, ka ʻoihana kemika, a me nā mea ʻē aʻe.

ʻO ka annealing mālamalamaHe kaʻina hana annealing i hana ʻia i loko o kahi ʻūhā a i ʻole ka lewa i mālama ʻia i loko o nā kinoea inert (e like me ka hydrogen). ʻO kēia ea i hoʻomalu ʻia e hōʻemi i ka hoʻoheheʻe ʻana o ka ʻili i ka liʻiliʻi e hopena i kahi ʻili māmā a ʻoi aku ka lahilahi o ka oxide. ʻAʻole pono ka pickling ma hope o ka hoʻoheheʻe ʻia ʻana mai ka liʻiliʻi o ka oxidation. No ka mea, ʻaʻohe pickling, ʻoi aku ka maʻalahi o ka ʻili i ka hopena i ke kūʻē maikaʻi ʻana i ka pitting corrosion.

ʻO ka lāʻau'ālohilohi e mālama i ka maʻalahi o ka'ōwili'ōwili, a hiki ke loaʻa ka'ōlinolino me kaʻole o ka hana hope. Ma hope o ka hoʻoheheʻe ʻana, mālama ka ʻili o ka paipu kila i ka luster metala maoli, a ua loaʻa kahi ʻili kukui kokoke i ke aniani. Ma lalo o nā koi maʻamau, hiki ke hoʻohana pololei ʻia ka ʻili me ka ʻole o ka hana ʻana.

No ka maikaʻi o ka annealing, hana mākou i nā ʻili o ka paipu maʻemaʻe a me ka ʻole o nā mea ʻē ma mua o ka annealing. A mālama mākou i ka lewa annealing i ka umu me ka ʻole o ka oxygen (inā makemake ʻia kahi hopena ʻālohilohi). Hoʻokō ʻia kēia ma ka hoʻoneʻe ʻana i nā kinoea āpau (hana ʻana i kahi ʻūhā) a i ʻole ma ka neʻe ʻana o ka oxygen a me ka nitrogen me ka hydrogen maloʻo a i ʻole argon.

ʻO ka hoʻoheheʻe ʻana i ka ʻulaʻula e hana i ka paipu maʻemaʻe loa. Hoʻokō kēia paipu i nā koi no nā laina lako kinoea hoʻomaʻemaʻe ultra kiʻekiʻe e like me ka maʻemaʻe o loko, ka maʻemaʻe, ka hoʻomaikaʻi ʻana i ka corrosion a me ka hoʻemi ʻana i ke kinoea a me ka hoʻokuʻu ʻana mai ka metala.

Hoʻohana ʻia nā huahana i nā mea kani pololei, nā lāʻau lapaʻau, ka ʻoihana semiconductor pipeline maʻemaʻe kiʻekiʻe, pipeline kaʻa, pipeline gas laboratory, aerospace a me ke kaulahao ʻoihana hydrogen (haʻahaʻa haʻahaʻa, puʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe). nā mahinaʻai.

Loaʻa iā mākou ma luna o 100,000 mau mika o ka waihona paipu, hiki ke hālāwai me nā mea kūʻai aku me nā manawa hoʻopuka wikiwiki.
