Ke hōʻike ʻia e nā ʻenekinia ʻO Sanicro28 nā ʻāpana mīkini kila kila, ʻaʻole lākou e koho wale i kahi huila ʻē aʻe - ke koho nei lākou i kahi mea i hana ʻia no ke ola ʻana i loko o ka chloride koʻikoʻi, ka waikawa, a me nā kaiapuni wela kiʻekiʻe. Akā hilinaʻi ka loaʻa ʻana ʻO Sanicro28 hale hana ʻāpana kila kila ʻO nā hoa pili e hoʻomau mau nei.

Ua ʻike mua mākou: ua haki ka hale pahū hydraulic ma 42 bar no ka mea ua hoʻokuʻu ka mea hoʻolako i ka hōʻoia hoʻonā hoʻonā; ʻAʻole i hoʻāʻo ʻia ka ʻili wai kai ma hope o ʻeono mahina-ʻaʻole ma muli o ka kemika o Sanicro28, akā no ka mea ʻaʻole i hoʻoponopono ʻia ka hoʻolei ʻana i ka hoʻoheheʻe ʻia *a * pickled i ka ASTM A967 Class VI.
No ke aha e koi aku ai ʻo Sanicro28 ma mua o ka hiki ke kila kila kila
ʻAʻole ʻo Sanicro28 (UNS N08028) he "wela kila ʻole me ka nickel keu." ʻO kāna 27% chromium, 31% nickel, 3.5% molybdenum, a me nā mea i hoʻopaʻa ʻia i ka nitrogen e hāʻawi i ke kūpaʻa kūʻokoʻa i ka pitting, crevice corrosion, a me ke koʻikoʻi corrosion pohā - akā ke mālama ʻia ka pono metallurgical ma kēlā me kēia pae. ʻO ia ke ʻano, ʻaʻohe ala pōkole i ka hiki ʻana o nā mea maka, ʻaʻohe kuʻikahi i ka hoʻonā ʻana i ka hoʻomalu wela annealing (1120–1180°C), a me ka ʻae ʻole no ka ʻike intergranular i ka wā wili a i ʻole ka hoʻokomo ʻana i ka wela machining. Loaʻa ka hapa nui o nā hale kūʻai kila kila maʻamau i ka calibration umu, ka nānā ʻana i ka lewa, a i ʻole nā protocol passivation post-machine. Mīkini lākou—akā ʻaʻole lākou * haku.
Ma QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mālama mākou iā Sanicro28 ma ke ʻano he ʻōnaehana hana — ʻaʻole he kikoʻī waiwai wale nō. Hele mai kēlā me kēia pūʻulu me nā hōʻike hoʻāʻo wili piha (MTRs) e hōʻoia ana i ka hoʻokō ʻana iā ASTM B673. Hoʻokomo ʻia nā pahu komo i ka spectrometry spark a me ka hōʻoia PMI ma mua o ka ʻoki ʻana. I ka hoʻohuli ʻana o CNC i nā kino valve kaomi, kaupalena mākou i ka spindle RPM a me ka helu hānai e hoʻopaʻa i ka wela o ka mea hana ma lalo o 300°C—e pale ana i nā papa hana paʻakikī e paʻa i nā chloride. Ma hope o ka hana ʻana, hele pololei nā ʻāpana i kahi umu hoʻomaʻemaʻe nitrogen no ka hoʻoheheʻe ʻana i ka hopena piha, a ukali ʻia e ka hoʻopau wai wikiwiki i hōʻoia ʻia e ka palapala ʻāina thermocouple. ʻAʻohe ea hoʻoluʻu. ʻAʻohe hui hui. ʻAʻohe manaʻo.
Hoʻoholo ʻia ka hoʻohui Vertical i ka Sanicro28 Consistency Gap
Nui nā hale hana i waho i ka hoʻolei ʻana, ka mīkini, a i ʻole ka hoʻopau ʻana—e hana ana i nā kiko lima kahi e hōʻemi ai ka hana a Sanicro28. Hiki ke hoʻoheheʻe pololei ʻia ka hale hana, akā inā ʻaʻole hoʻololi ka mīkini no ka hana wela haʻahaʻa haʻahaʻa o Sanicro28 40% ma mua o 316 stainless, hoʻopau ka deflection mea hana i nā kelepona GD&T. Inā hoʻohana ka mea hoʻomaʻamaʻa wela i kahi ea ʻaʻole inert, hoʻoheheʻe ʻia nā chromium carbide ma nā palena o ka palaoa-pepehi ʻana i ke kūpaʻa ʻana.
Hoʻopau mākou i kēlā mau āpau. ʻO kā mākou mea hoʻokō ISO e mālama i nā mea a pau i loko o ka hale: ka hoʻolei kālā ʻana i nā hale cylinder paʻakikī, multi-axis CNC machining o nā piston pump flanges me ± 0.01 mm positional tolerance, a me ka electropolished surface finishing to Ra ≤ 0.4 µm. No Sanicro28 winch center shaft rollers, hoʻolei mākou i nā ʻano ʻupena kokoke, a laila hana mākou i ka hoʻoheheʻe ʻana i ke kaumaha ma mua o ka hoʻohuli paʻakikī hope loa - e hōʻoia i ka paʻa microstructural ma lalo o ka ukana torsional cyclic. Hāʻawi kēlā me kēia ʻāpana i ka hiki ke ʻike piha ʻia: helu nui, MTR ID, log mālama wela, hōʻike CMM, a me ka palapala hōʻoia o ka ʻili.
- Sanicro28 kaomi kaomi - mīkini ʻia mai ka billet forged, ASME B16.34 helu ʻia, hydrotested i 1.5 × MAWP
- Pum kumu — hoolei one me na lugs hookui, hoomaha i ke kaumaha, a me ka honua i ka palahalaha ≤ 0.05 mm/m

ʻO ka hōʻoia ʻana i ka honua maoli, ʻaʻole ka hoʻokō pepa wale nō
Nīnau nā mea kūʻai: "Hiki iā ʻoe ke hālāwai me NACE MR0175/ISO 15156 no ka lawelawe ʻawaʻawa?" ʻAe—akā ma hope wale nō o ka hōʻoia ʻana i kēlā me kēia holo hana no ka ASTM G48 Method A (ferric chloride pitting test) a me ASTM G123 (crevice corrosion test). ʻAʻole mākou e hilinaʻi i nā palapala hōʻoia generic alloy. Hoʻāʻo mākou i kāu ʻāpana, ma *kou geometry*, me ka hoʻohana ʻana i kāu wahi lawelawe i manaʻo ʻia. Pono kekahi mea hoʻohana o ke Kai ʻĀkau he 1,000-hola ka hoʻokomo ʻana i loko o ka wai kai synthetic ma 80°C.

Hoʻopili ʻia kēlā aʻo i ka logistic. ʻO nā ʻāpana ʻo Sanicro28 i hoʻopaʻa ʻia me ka pepa VCI-ʻaʻole i ʻōwili ʻia i loko o ka plastic e paʻa ana i ka makū. Loaʻa i ka palapala nā moʻolelo nānā piha, ʻaʻole kahi ʻōlelo conformance wale nō. A hoʻomaka ke kākoʻo ʻenekinia ma mua o ka PO: nānā kā mākou hui i kāu GD&T, hōʻike i ka hoʻopilikia ʻana i ka mīkini i loko o nā lua hoʻomanawanui, a manaʻo e hoʻololi i nā hoʻololi e hōʻemi i ka hoʻopaʻa ʻana i ke kaumaha—no ka uku ʻole.
Ke koho ʻana i kāu hale hana ʻāpana mīkini kila ʻole ʻo Sanicro28
ʻAʻole ʻōlelo wale ka hoa kūpono iā Sanicro28-ua maopopo iā lākou ke kumu āu i koho ai. ʻIke lākou he 0.02 mm ka hoʻokaʻawale ʻana i loko o kahi ʻāpana seal ʻaʻole ia "no ka hoʻomanawanui" - he ala ia no ka komo ʻana o ka chloride. Hana lākou i kāu kaha kiʻi ʻaʻole ma ke ʻano he papa kuhikuhi, akā ma ke ʻano he palapala hana.
Inā koi kāu noi i ke kūpaʻa ʻana i ka corrosion hiki ke wānana, ka kūpaʻa o ke kūkulu ʻana ma lalo o ka ukana cyclic, a me ka paʻa ʻana o ka dimensional ma waena o nā pōʻai wela—a laila ʻoi aku ka nui o ka pololei ma mua o ke kumukūʻai. Pono ʻoe i kahi ʻO Sanicro28 hale hana ʻāpana kila kila nāna e hoʻomalu i ke kaulahao holoʻokoʻa: nā mea maka i hōʻoia ʻia, ka hoʻoponopono ʻana i ka wela, ka nānā ʻana i ka metrology-grade, a me ka traceability i kākau ʻia. ʻAʻole kahi e nānā i nā pahu. ʻO kahi mea e pale ai i nā hemahema ma mua o ka hiki ʻana mai.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. kūkulu ia mau ʻāpana—i kēlā me kēia lā, no nā mea kūʻai aku ma ʻEulopa, ʻAmelika ʻĀkau, a me Asia Hikina Hema. No ka mea i loko o nā wahi paʻakikī, ʻaʻole koho ka hilinaʻi. Ua hana ʻia.
