Hoʻopau nā ʻāpana huila Monel i hoʻokahi pilikia hoʻomau: ka hiki ʻole o ka corrosion i nā wahi ʻoihana koʻikoʻi. Ua ʻike mākou i ka haki ʻana o nā kino valve hydraulic ma hope o 18 mau mahina ma nā ʻōnaehana hoʻoluʻu wai kai. Ua pani mākou i nā hale pahū i hoʻopau ʻia e nā wai puna wai ʻaila piha i ka H₂S—ʻelua ʻelua i ka makahiki hoʻokahi. ʻAʻole i manaʻo ʻia ka hana ʻana o ka ʻāpana alloy Monel. Ana ia i ka uptime, ka mālama ʻana, a me ka pale ʻana i ka pani ʻana.
No ke aha i ʻoi aku ka maikaʻi o nā ʻāpana Alloy Monel i nā Alloy maʻamau i ka lawelawe honua maoli
ʻO nā huila Monel—ʻo ia hoʻi ʻo Monel 400 a me Monel K-500—he mau binaries nickel-copper me ke kū kūʻokoʻa i ka hoʻohaʻahaʻa ʻana i nā waikawa, ka wai paʻakai, a me nā hopena alkaline. ʻAʻole like me nā kila kila e hilinaʻi nei i nā papa ʻokikene passive, kūʻē ʻo Monel i ka pitting a me ke kaumaha-corrosion pohā me ka ʻole o nā kiʻiʻoniʻoni. He mea nui ia i ka wā e hoʻomau mau ʻia ai ka pahu paʻi ma 350 bar i loko o nā manifold hydraulic waho-a i ʻole i ka wā e holo ai ka pahu piston pump cylinder housing ma waena o ka brine injection a me ka ʻike kinoea ʻawaʻawa.
Hoʻāʻo mau mākou iā Monel 400 e kūʻē i ka 316 stainless steel ma lalo o ka ASTM G48 ferric chloride immersion like. Hōʻike nā hopena i ka lua ʻole ma hope o 72 mau hola no Monel; Hoʻokumu ʻo 316 i nā lua i ʻike ʻia i loko o 6 mau hola. Ma nā hoʻolālā kahua maoli, ʻoi aku ka lōʻihi o nā ʻāpana hui Monel 3-5x ma mua o nā mea ʻē aʻe duplex stainless i loko o nā kaiapuni chloride-sulfide i hui pū ʻia i nā lako lawelawe ʻaila.
Akā ʻaʻole ʻo ka koho waiwai wale nō e hōʻoia i ka holomua. He lāʻau Monel 400 me nā māwae hoʻomaʻamaʻa wela kūpono ʻole ma lalo o ka haʻawe torsional cyclic. ʻO kahi impeller Monel K-500 i hoʻohana ʻia me nā mea hana carbide kahiko e loaʻa i ka micro-haehae e hoʻomaka ai i ka luhi luhi. ʻO ia ke kumu ʻaʻole koho ʻia ka hana pololei - ʻo ia ka hapa ʻelua o ka hoʻohālikelike ʻana i ka corrosion-resistance.
Pehea e mālama ai ka mīkini pololei i ka pono o Monel
ʻO nā huila monel e hana wikiwiki. Kiʻekiʻe loa ka nui o nā meaʻai no ka hoʻohuli ʻana i ka mea paahana a me ke ana ʻana. ʻO ka ʻoki haʻahaʻa haʻahaʻa loa e hoʻoulu i ka wela nui-a hoʻopili i ka papa kokoke i ka ʻili, e hōʻemi ana i ka ikaika. Hoʻohana mākou i nā paepae CNC multi-axis me ka nānā ʻana i ka ukana spindle manawa maoli no ka mālama ʻana i ka ukana chip maikaʻi loa. No ka laʻana, pono ke kahua pahū Monel 400 i ± 0.01 mm palahalaha ma kahi o 420 mm. ʻO ka loaʻa ʻana o ia mea e koi ana i ka uku wela, ka hōʻoia CMM i loko o ke kaʻina hana, a me ka mālama ʻana i ka wela ambient-ʻaʻole wale i ka mea hana maikaʻi.
Hoʻopili pololei ka hoʻopau ʻana i ka ʻili i ka hana ʻino. ʻO kahi Ra 3.2 μm hoʻopau ma Monel K-500 i loko o kahi pahu wai hoʻololi e hōʻike ana i ka hoʻouka kūloko ma hope o 14 mau mahina. ʻO ka ʻāpana like i hoʻopau ʻia i Ra 0.8 μm e paʻa mau i 36 mau mahina. Hoʻohui mākou i ka electropolishing a me ka passivation i loko o kā mākou kaʻina hoʻopau - ʻaʻole ma ke ʻano he mea hoʻohui, akā ma ke ʻano he hana hana i kūlike me nā kūlana ASME BPE no nā ala wai koʻikoʻi.
Hiki i kekahi ke hoʻopaʻapaʻa e hāʻawi i nā ʻāpana kobalt i ʻoi aku ka maikaʻi. ʻOiaʻiʻo—akā, hāʻawi nā kobalt alloys i ka pale ʻana i ka corrosion i ka hōʻemi ʻana i nā kaiapuni. Ua lanakila 'o Monel ma kahi o nā waiwai 'elua: nā hui pauma e lawelawe ana i ka wai kai + hydrogen sulfide, a i 'ole nā wili pahu waena winch i 'ike 'ia i ka ehu pa'akai kahakai a me ka abrasion mechanical.
Mai ka ʻimi ʻana i nā mea waiwai a hiki i ka hoʻouna ʻia ʻana
ʻAʻole like nā Monel a pau. Hoʻokumu wale mākou i ka Monel 400 a me K-500 i hōʻoia ʻia i ka wili mai nā mea hoʻolako hoʻokō ʻo ASTM B164-me ka ʻike wela piha a hiki i ka helu ladle. Loaʻa kēlā me kēia pūʻulu i ka loiloi spectrographic a me ka hoʻāʻo tensile ma mua o ka hoʻomaka ʻana o ka mīkini paʻakikī. No ke aha mai? No ka mea, hoʻohaʻahaʻa ke kalapona ma luna o 0.023% i ka weldability; ʻO ka sulfur ma luna o 0.001% e paipai ana i ka pohā wela i ka wā e hoʻoponopono ai.
ʻO kā mākou keʻena ISO-compliant e lawelawe i ka holo holoʻokoʻa: ka hoʻolei kālā no nā geometries paʻakikī e like me nā nozzles Monel, ka hoʻohuli ʻana a me ka wili ʻana o CNC no nā hale hoʻomanawanui paʻa, a me ka mālama wela ma AMS 2750. Loaʻa i kēlā me kēia ʻāpana hui Monel ka nānā hope loa me ka hoʻohana ʻana i nā mīkini ana coordinate a me nā mea hoʻohālikelike optical — hōʻoia ʻia e kūʻē i nā kelepona GD&T wale nō.
- ʻO nā pahu kaomi: ASME Māhele VIII hoʻokō, hydrotested i 1.5 × hoʻolālā kaomi
- Piston pump cylinder housing: Ua hōʻoia ʻia ka paʻakikī ma waena o ka lua, flange, a me nā ʻili e kau ana
- ʻEnekinia kaʻa winch shafts: Ultrasonic i ho'āʻo no subsurface discontinuities
- Nā ʻāpana maʻamau ʻole: Nā palapala hōʻoia piha, nā moʻolelo mālama wela, a me nā hōʻike dimensional i hoʻouna ʻia me kēlā me kēia kauoha
Ke koho ʻana i ka hoa kūpono no nā ʻāpana huila Monel koʻikoʻi
Hoʻomaka ka pale ʻana me ka metallurgy—akā e pau me ka hoʻokō. ʻO ka mea hoʻolako i hoʻopaʻa i ka waihona pahu ʻo Monel akā ʻaʻohe ʻike i ka mīkini e hāʻawi ʻo ia i nā ʻāpana me ke koena o ke koʻikoʻi, kahe ʻai ʻole like ʻole, a i ʻole ka lepo. Pono ʻoe i ka hiki ke hoʻāʻo ʻia me AMS 5387 cobalt-nickel grades, T800-based alloys, a hybrid casting-machining process—ʻaʻole wale nā papa inoa papa inoa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ke kūkulu nei i nā ʻāpana huila Monel no nā mea kūʻai aku ma ʻAmelika ʻĀkau, ʻEulopa, a me ʻĀsia Hikina Hema - nā ʻāpana e hana ana i loko o nā modula hoʻokele subsea, nā laina lawelawe waika refinery, a me nā ʻōnaehana hydraulic moana. ʻO kā lākou kaʻina hana i hoʻohui ʻia e hoʻomalu i ka microstructure integrity, dimensional stability, a me ka maikaʻi o ka ʻili mai ka mea maka a hiki i ka ʻāpana pau. Hoʻopaʻa koke lākou i ka hana ʻana, hae hae GD&T ma mua o ka ʻoki ʻana i ka metala, a mālama i ka traceability piha no kēlā me kēia mea koʻikoʻi.
Ke lilo ka manawa hoʻohaʻahaʻa i $250,000 / hola a me nā manawa alakaʻi hou i hala he 12 mau pule, ʻaʻole pili ka hana ʻana o Monel alloy i nā kikoʻī ma ka pepa. E pili ana i ka mea e ola ai-a e hoʻopakele ai-ma lalo o ke kaomi maoli, kemika maoli, a me nā lā palena hana maoli.
