ʻAʻole pale wale nā mea kila kila - paʻa lākou i ke kaomi, ola i ka abrasion, a mālama i ke kūpaʻa dimensional inā ʻaʻole he koho ka hemahema. I loko o ka hydraulic manifolds i helu ʻia no 350 bar, i loko o nā hale pahū e wili ana ma 3,600 RPM ma lalo o ka slurry abrasive, a i ʻole ma nā ʻaoʻao winch kikowaena waho i hōʻike ʻia i ka makani paʻakai a me ka torque cyclic - ʻaʻole "maikaʻi loa kēia mau ʻāpana." He mau heleuma koʻikoʻi lākou. Ua ʻike mākou i ka haki ʻana o nā pahu mai ka chloride-induced stress corrosion ma nā mea kanu desalination o Asia Hema. Ua hoʻololi mākou i nā hale cylinder i hoʻopaʻa ʻia ma hope o 18 mau mahina o ke kaʻa kaʻa wela ma nā ʻaila ʻaila ʻAmelika ʻĀkau. Ua aʻo mai kēlā me kēia hāʻule iā mākou i hoʻokahi mea: ʻaʻole he koho waiwai ke kila kila - he hoʻoholo pae ʻōnaehana.
No ke aha i ʻoi aku ka maikaʻi o nā ʻāpana kila kila i nā ʻano ʻē aʻe ma ka lawelawe honua maoli
Hoʻopili wikiwiki ka alumini i ka wai chlorinated. Pono ke kalapona kalapona i ka pena mau—a hiki ole ka poino ke pa'i ka uhi. ʻO nā kila kila ʻole Duplex e like me UNS S32205 e hāʻawi i nā ikaika hua ma luna o 450 MPa i ka wā e pale ana i ka lua i loko o ka wai kai. Akā ʻo ka ikaika wale nō ʻaʻole ia e hōʻoia i ka hana. Ho'āʻo mākou i kēlā me kēia pūʻulu o 316 mau mea hoʻolei kila kila no ka maʻiʻo ferrite (pahu: 4-7%); ʻO ka liʻiliʻi loa e hoʻoemi i ka paʻakikī. ʻO ia ke kumu o kā mākou mea kūʻai aku i nā OEM kaʻa ʻenekinia ʻEulopa e kuhikuhi i ka ASTM A995 Grade CD4MCu-ʻaʻole no ka mea he "stainless," akā no ka mea e ola ana kāna microstructure ʻelua-phase i ka hoʻouka pinepine ʻana i nā wili winch ma luna me ka ʻole o ka microcrack propagation.
ʻAʻole manaʻo ka pale ʻana i ka corrosion. Ua ana ʻia i nā hola o ka hoʻoheheʻe ʻia ʻana o ka paʻakai (ASTM B117), i hōʻoia ʻia e ka cross-section SEM imaging o ka mānoanoa kiʻiʻoniʻoni passive, a hōʻoia ʻia i ka lawelawe wai maoli. I ka wā i hoʻololi ai ka mea hana pauma US mai ka 304 a i ka 316 mau mea kila kila no nā laina hoʻololi kemika, ua emi iho ka manawa hoʻohaʻahaʻa i ka 62%—ʻaʻole mai ka mīkini ʻoi aku ka maikaʻi, akā mai ka hoʻopau ʻana i ka ʻinoʻino i kōkua ʻia e ka chloride ma nā pilina flange. ʻAʻole ʻokoʻa ka papa alloy wale nō. Ua mālama ʻia ka mālama ʻana i ka wela (ka hoʻoheheʻe ʻana i ka hopena ma 1040–1120°C, ka hoʻopau wikiwiki ʻana), ka mana hoʻopau ʻana i ka ʻili (Ra ≤ 0.8 µm ma nā ʻili e hoʻopaʻa ʻia), a me ka traceability piha i ka hoʻoheheʻe kemika.
Kahi e hāʻule pōkole ai nā ʻāpana Catalog maʻamau—a me nā mea e pono ai nā ʻenekinia
Hiki i kekahi ke hoʻopaʻapaʻa ʻo ka mālama ʻana i ka manawa a me ke kumukūʻai o nā mea kila kuhili ʻole ma waho o ka papa. Akā ʻo nā hoʻolaha honua maoli e haʻi i kahi moʻolelo ʻē aʻe. Ua loaʻa i kahi mea hoʻolaha valve hydraulic Kelemania nā kino 316L maʻamau no nā kaapuni pailaka kiʻekiʻe-e ʻike wale i ka porosity kūloko kū ʻole ma hope o ka hoʻāʻo ʻana i ke kaomi ma 420 bar. ʻAʻole i ʻike ʻia nā leaks ma nā sila, akā ma loko o nā hakahaka o lalo ma kahi kokoke i nā ʻīpuka. ʻO kā lākou hoʻoponopono? Hoʻolālā hou i ka ʻōnaehana casting gating a me ka hoʻololi ʻana i nā ʻāpana hoʻokele waiwai me ka nānā X-ray no ASTM E94. ʻAʻole kēlā i ka ʻenehana nui. ʻO ia ka physics.
