Ke hōʻike ʻia e nā ʻenekinia ʻO nā kī monel no nā ʻauwaʻa ma waho o ka moana, nā ʻāpana o lalo o ka moana, a i ʻole nā ʻōnaehana hana kemika kiʻekiʻe, ʻaʻole lākou e kūʻai i nā mea hoʻopaʻa - ke hoʻopaʻa nei lākou i ka kūpaʻa koʻikoʻi. ʻAʻole lawa ka pale ʻana i ka corrosion wale nō. He mea nui ke kūpaʻa wela. ʻO ke kūpaʻa ʻana ma lalo o nā mea hoʻokau hoʻomau. ʻO ka paʻa ʻana o ka hui pū ʻana i ka ikaika tensile a me ka hoʻokumu ʻana i ka palaoa. ʻO ia ke kumu e loaʻa ai mai kahi ʻoiaʻiʻo hale hana wili monel-ʻaʻole wale he mea hoʻolaha a hale kūʻai hana paha - ʻaʻole hiki ke kūkākūkā.
Ua ʻike mākou i nā papahana he nui i hoʻopaneʻe ʻia e nā bolts i hala i ka nānā ʻana akā ʻaʻole i hāʻule i ka hoʻāʻo ʻana i ka paʻakai ma 1,200 hola. Ua pohā kekahi i ka wā kaʻa kaʻa wela ma waena o –60°C a me +450°C—ʻaʻole no ka nāwaliwali o ka huila Monel, akā no ka mālama ʻole ʻana i ka wela a i ʻole ka hana anu kūpono ʻole i waiho ʻia ke koena koʻikoʻi ʻaʻole i ʻike ʻia a hiki i ke kau ʻana o ke kahua. Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mākou mīkini Monel 400 a me Monel K-500 bolts i loko o ka hale, e hoʻomaka ana me ka ASTM B164-hōʻoia bar stock, a laila e noi ana i hoʻomalu 'ia ka hopena annealing a me ka makahiki-paʻakikī no AMS 5643. kela hailona undergoes spark emission spectroscopy a me ka paʻakikī. ʻike—ʻaʻole nā hōʻailona laʻana wale nō.
He aha ka mea e hoʻokaʻawale ai i kahi hiki hale hana wili monel mai ka mea hoʻolako waiwai? ʻEkolu mau mea: ka mana metallurgical, dimensional discipline, a me ka hōʻoia hana. ʻO ka mea mua, metallurgy. ʻO ka paʻakikī o ka ua ʻo Monel K-500 e pili ana i nā ratio nickel-aluminum-titanium pololei a me nā puka makani wela. Hoʻohui pū mākou i nā mea waiwai me nā mea hoʻolako i hōʻoia ʻia, mālama i ka hiki ʻana o ka wela piha a hiki i ka helu log ingot, a hōʻoia i ka pane ʻana o ka wā kahiko me nā coupons tensile i ʻoki ʻia mai ka billet i hoʻohana ʻia no ka hana bolt. ʻO ka lua, ke aʻo dimensional. ʻO ke kaula papa 3A ma ka pahu Monel e koi aku i ka ʻoi aku ka paʻa o ke anawaena pitch (± 0.0015') ma mua o ke kila kila maʻamau. ʻO kā mākou mau kikowaena hoʻohuli CNC 5-axis e paʻa i ka ± 0.0008 'ma nā anawaena koʻikoʻi; Loaʻa ka hōʻoia CMM i ka hewa alakaʻi kaula, ka ʻae ʻana o ka ʻaoʻao, a me ka holo ʻana—hōʻike ʻia nā mea a pau ma ka ASME B1.13M. ʻO ke kolu, hōʻoia hana. ʻAʻole mākou e hoʻomaha ma nā ʻōkuhi torque-tension. No nā mea kūʻai aku i ka aila a me ke kinoea, hana mākou i nā hoʻokolohua lawelawe hoʻohālikelike: 72-hola immersion i ka H₂S-saturated brine ma 120°C, a ukali ʻia e ka hoʻouka ʻana i ka 90% o ka ikaika hua i kuhikuhi ʻia i ka nānā ʻana no ka microslip a i ʻole ka hoʻomaha.
Hiki i kekahi ke hoʻopaʻapaʻa ʻaʻole hiki ke hoʻohālikelike i nā ʻāpana Monel i hoʻokumu ʻia i ka hoʻolei ʻana i nā waiwai waiwai. Ua pololei lākou - no nā bolts. Akā ʻo ia ke kumu e pale ai mākou i ka hoʻolei ʻana i nā mea paʻa Monel. Akā, hoʻohana mākou i ka pahu pahu wela a huki anu paha, a laila e hoʻohana i ka huli pololei, ka ʻōwili ʻana i ke kaula (ʻaʻole ʻoki), a me ka electropolishing koho no ka hoʻonui ʻana i ke kiʻiʻoniʻoni passive. ʻO ka ʻōwili ʻia ʻana o ka milo e hoʻopaʻa i ke ʻano o ka palaoa ma ka ʻili, e hoʻonui ana i ke ola luhi a hiki i ka 30% ma mua o nā kaula ʻoki. Hoʻopaʻa mākou i kēia me ka hoʻāʻo ʻana i ka luhi ʻo rotating-beam ma kēlā me kēia ASTM E466, e hōʻike ana i nā pihi S-N ma nā pōʻai 10⁷. No nā geometries maʻamau-e like me nā bolts flange me nā lugs grounding i hoʻohui ʻia a i ʻole nā papa anti-rotation - ʻenehana mākou i nā mea hana maʻamau i loko o ka hale, e hoʻopau ana i nā lohi o nā ʻaoʻao ʻekolu a me ka hōʻoia ʻana i ka hoʻokō GD&T mai ka prototype mua a i ka hana piha.
ʻAʻole kūkulu ʻia ka hilinaʻi i loko o kahi bolt Monel i ka hoʻouna ʻana. Hoʻokumu ʻia i loko o ke kaʻina hana ma mua o ka lele ʻana o ka chip mua. ʻO ia ke ʻano o ka nānā ʻana i nā mea me nā mea loiloi PMI-ʻaʻole wale nā palapala wili. Hoʻoponopono kaʻina hana ma hope o ka huli ʻana, ma hope o ka mālama ʻana i ka wela, ma hope o ka ʻōwili ʻana o ka milo, a ma hope o ka hoʻomaʻemaʻe hope ʻana. ʻO ka nānā hope loa e pili ana i ka hoʻāʻo ʻana i nā ʻāpana magnetic no nā hemahema o lalo o ka ʻāina, ka hōʻoia ʻana i ka bake-out o ka hydrogen embrittlement (ma ka ASTM F519), a me ka hoʻopili ʻana i ka pepa VCI me nā hōʻailona haʻahaʻa. Hoʻouna ʻia kēlā me kēia kauoha me kahi hōʻike hoʻāʻo piha: kemika, nā mīkini, nā hopena NDT, a me ka ʻikepili dimensional i hoʻopaʻa ʻia e kā mākou hui QA i hōʻoia ʻia i ka ISO 9001. Hāʻawi mākou i nā mea kūʻai mai Houston a Hamburg a me Singapore—ʻaʻole ma o nā brokers, akā ma o ka hana ʻenehana pololei. I ka wā e kū ai kāu mau pahu pahu pahu i 20,000 psi ke kaomi ʻokoʻa a me ka mahu i hoʻopiha ʻia me ka chloride, "maikaʻi" ʻaʻole ia he koho. ʻAʻole koho ka pololei. ʻAʻole koho ka traceability. ʻAʻole koho ka ʻike me Monel. E koho i kahi hale hana wili monel e mālama i kēlā me kēia bolt e like me kahi mea i loko o kahi ʻōnaehana kākoʻo ola-no ka mea i nā manawa he nui, ʻo ia.
