He aha ka ASTM composite panel exporter no nā mea kanu desalination?
ʻO kahi ASTM composite panel exporter no nā mea kanu desalination he mea hoʻolako loea nāna e hāʻawi i ka lole bimetal nā papa—e like me ke kila titanium, kila kila-carbon steel, a me nickel alloy-steel—hana ʻia e like me nā kūlana ASTM (e like me ASTM B898) no ka hoʻohana ʻana i nā keʻena desalination thermal a reverse osmosis. Ke nānā nei mākou i hoʻokahi mea: ka hāʻawi ʻana i nā panela metala hōʻole i ka corrosion-proof e ola ana i nā makahiki he nui i ka wela kiʻekiʻe, ka wai kai kiʻekiʻe a me nā kaiapuni brine.
ʻAʻole kēia mau ʻāpana metala maʻamau. Hoʻohui ʻia kahi ʻāpana hui i kahi lahilahi, mea hoʻopaʻa paʻa i ka corrosion (titanium, SS316L, a i ʻole Hastelloy C276) paa i ka manoanoa, kākoʻo kalapona ikaika. ʻO ka hopena? ʻO kahi mea e kūʻē i ka hoʻouka ʻana i ke kai akā lawe maikaʻi i nā haʻahaʻa kūkulu, nā mea a pau me ke kumu kūʻai ʻole o kahi titanium paʻa pāpaʻa.
No ke aha i hoʻopaʻa ʻia ai ke kila titanium a me ke kila kila kila no ka desalination?
He ʻino ka wai kai. Klorida, sulfates, a me ka hoʻouka kaua biofouling a hiki i nā kila kila. ʻO ia ke kumu i makemake ai mākou i ke kila titanium (no ka ASTM B898) no nā mea hoʻololi wela a me nā evaporators. ʻAʻole hiki ke pale ʻia ka Titanium i ka ʻinoʻino ʻana o ke kai a hiki i 260°F (127°C). Ke kila kila 316L huikau hana nā paneli i nā ʻāpana liʻiliʻi, hāʻawi maikaʻi i ke kūʻē pitting ma ke kumu kūʻai haʻahaʻa.
ʻO nā huila nikela e like me Inconel 625 a me Hastelloy C276 aahu nā papa mālama i ka wai wela wela a me ka waika hydrochloric hoʻomaʻemaʻe. No ka mea hana mea kanu, iho ka koho i ka wela hana, ka hoʻopaʻa ʻana o ka chloride, a me ka pH. ʻIke mākou i kēia no ka mea ua ʻike mākou i ka pau ʻana o nā panela i nā mahina i koho ʻia ai ka alloy hewa.
He aha nā noi nui i loko o kahi mea kanu desalination?
ʻIke mākou huikau nā panela i ʻekolu mau wahi nui: nā mea hoʻololi wela, evaporators, a me na moku kaomi.
- Nā mea hoʻololi wela: ʻO nā ʻili a me nā ʻauwaʻa i hoʻopaʻa ʻia i ka Titanium e pale i ka wai kai kahe wikiwiki, e hoopau ana i ka poino galvanic ma na hui paipu-i-pepa.
- Nā mea hoʻoheheʻe: I loko o ka flash multi-stage (MSF) mea kanu, SS316L nā papa hoʻohuihui e laina i ka mea hoʻomehana brine a me nā ʻāpana hoʻihoʻi, me ka pale ʻana i nā wela kiʻekiʻe a me ka scaling.
- Nā moku kaomi: ʻOsmosis hoʻohuli (RO) hoʻohana nā moku i nā pāpaʻi kila kila e loaʻa ai ka wai kai piʻi kiʻekiʻe me ka ʻole o ka pohā a me ka lua.
I kēlā me kēia hihia, hāʻawi ke kākoʻo kila i ka ikaika, a ʻo ka pale ʻana i ka hakakā ʻana i ka pala. Ua nānā mākou i nā mea kanu ma hope 15 makahiki o ka lawelawe ana—e like me ka mea hou na panela mai ka mea hoopuka aku i ka ASTM.
Hoʻopaʻa pahū vs paʻa ʻōwili: i kūpono i ka desalination?
Loaʻa iā mākou kēia nīnau i nā manawa a pau. Hana nā ʻano ʻelua, aka, aole hiki ke hoololiia.
Pahū pahū hoʻohana i ka hoʻoheheʻe ʻia e hoʻohui i nā metala me ka hoʻoheheʻe ʻole. Hāʻawi ia i kahi paʻa metala ʻoiaʻiʻo e lawelawe ana i ka paikikala wela a me ka haʻalulu wela i nā mea hoʻololi wela desalination. Hana ia no ka titanium a i ke kila—he hui hiki ʻole ke ʻōwili i ka paʻa ma muli o ke ʻano o ka intermetallic brittle. No ke kila aahu titanium, ʻO ka pahū pahū ke ala wale nō.
Hoʻopaʻa ʻōwili He wela ka owili ana i elua metala. Ua kūpono i ke kila kuhiliʻole i ke kila kalapona, a ʻoi aku ka maikaʻi o ke kumukūʻai no nā papa lahilahi. Akā ʻaʻole hiki ke hoʻopaʻa paʻa i ka titanium i ke kila. Inā hāʻawi ka mea hoʻolako i ka pā kila titanium i hoʻopaʻa ʻia, hele aku. Ua ʻike mākou i nā hemahema delamination ma lalo o ʻelua mau makahiki.
No ka desalination, Paipai mākou i ke kila pahū i hoʻopaʻa ʻia i ka titanium no nā pepa paipu, a me ke kila SS316L i hoʻopaʻa ʻia no nā pūpū evaporator kahi i emi iho ai ka mānoanoa o ka lole..
He aha ka ho'āʻo NDT e koi ai iā ASTM?
ʻO ka ASTM B898 a me nā kūlana pili e koi i ka hoʻāʻo ikaika ʻole (NDT). Ke hilinaʻi nei mākou i ʻekolu mau hoʻāʻo koʻikoʻi e hōʻoia i ka pono pili.
- Ka ho'āʻo kani kani (UT): Ka nānā ʻana 100% o ka pilina pili. ʻO kahi ʻāpana i hoʻopaʻa ʻole ʻia ʻoi aku ka nui ma mua o 3 'īniha ma kekahi ʻaoʻao he hōʻole. Hoʻohana mākou i ka UT beam-pololei a me ka angle-beam e hopu i nā disbonds lihi.
- ʻO ka hoʻāʻo ikaika shear: He ho'āʻo hoʻopōʻino ma kahi laʻana mai kēlā me kēia pā. ʻO ka ikaika ʻoki liʻiliʻi no ka titanium-steel 20 ksi (140 MPa). Ma lalo o kēlā, ʻAʻole e ola ka paʻa i ke kaumaha wela.
- Hoʻo piʻo: Ke kulou ʻana i kahi hōʻailona 180 degere. ʻAʻole ʻae ʻia ka māhā a kaʻawale paha ma ka interface.
Pono e loaʻa i kahi mea kūʻai aku ʻo ASTM composite panel no nā mea kanu desalination i loko o ka hale UT. Makemake mākou i nā mea hoʻolako e kaʻana like i nā scan UT, ʻaʻole wale ka palapala hōʻoia. Hoʻokumu kēlā ʻike maopopo i ka hilinaʻi.
ʻO ka nui maʻamau a me ka mānoanoa pā no nā papahana desalination
ʻAʻole ma waho nā mea kanu desalination. Pono paha kahi pepa paipu hoʻokahi i ke kākoʻo kila mānoanoa 4-ʻīniha me ka 3/16-inch titanium cladding., a me kahi kapuai o 12 wawae e 6 wāwae.
Hoʻokumu pinepine mākou i nā panela me kēia mau ʻāpana:
- mānoanoa holoʻokoʻa: 6 mm i 100 mm (0.24 i 4 iniha).
- ʻAʻahu mānoanoa: 2 mm i 10 mm (0.08 i 0.4 iniha).
- Ka nui o ka pā: A hiki i 4 mika e 12 mika (13 na 40 wāwae), kaupalena wale ʻia e ka hale hoʻopaʻa pahū.
Inā ʻaʻole hiki i ka mea kūʻai aku ke mālama i kēlā nui, pono ʻoe e wili i nā ʻāpana he nui. He mea paʻakikī ke kuʻi ʻana i nā papa ʻaʻahu—pono ʻoe i kahi papa pata no ka pale ʻana i ka haki. Ke noi mau nei mākou i ka hana ʻāpana hoʻokahi.
He aha nā palapala hōʻoia e loaʻa i ka mea hoʻopuka?
He mea nui nā palapala hōʻoia ʻekolu. Ka mua, ISO 9001 hōʻoia i ka maikaʻi o ka hana ʻana. Ka lua, IN 10204 ʻAno 3.2 ʻae ka palapala hōʻoia i kahi mea nānā ʻekolu (e like me DNV a i ʻole Lloyd) e ʻike i ka hoʻāʻo ʻana a hōʻailona. Ke kolu, pono e hoʻokō ka mea kūʻai aku me ka maʻamau ASTM kikoʻī no kāu noi-B898 no ka titanium-steel, B898 no ke kila kila, a i ʻole B432 no ke kila keleawe.
Ke noi mau nei mākou i kahi hōʻike hoʻāʻo waiwai (MTR) e pili ana i ke kemika maoli, ʻano mekini, a me nā hopena UT. Me ka MTR ʻole, ke kali wale nei ka papa e hāʻule.
Ka hoʻolako kaulahao a me ke alakaʻi manawa noonoo
Pono pinepine nā papahana desalination nui i nā haneli o nā ʻāpana paipu a me nā haneli mau mika square o ka pā lole. ʻO ka manawa alakaʻi no nā paneli hoʻopaʻa paʻa i ka maʻamau 12 i 16 pule mai ke kauoha. Lawe ʻia nā panela ʻōwili 8 i 12 pule pule.
Hoʻohui mākou: kūʻai waiwai maka, pahū pahū a ʻōwili paʻa, lapaʻau wela (e hoʻihoʻi i ka ductility), NDT, a me ka mīkini hope. Inā aia ka mea hoʻopuka i waho, hoʻohui 4 i 6 nā pule no ka hoʻouna ʻana a me ka dute. Ke kauoha mau nei mākou i kahi pale o 10% paʻa hou no ka weld hōʻike coupons a me ka hana hou.
Uku-pono: hoʻopukapuka mua vs mālama mālama wā lōʻihi
ʻOi aku ke kumukūʻai o ka pā lole ma mua o ke kila kalapona paʻa akā ʻoi aku ka liʻiliʻi ma mua o ka titanium paʻa a i ʻole ka nickel alloy. A typical titanium-aahu kila paipu pepa koina e pili ana 30% ʻoi aku ma mua o kahi SS316L paʻa. Akā e noʻonoʻo i ke ola.
ʻO SS316L paʻa i loko o kahi mea hoʻomehana brine e mau paha 5 makahiki ma mua o ka hoʻomaka ʻana o ka lua. E mau ana ke kila aahu Titanium 20+ makahiki me ka ʻino ʻole. ʻEhā mau pani i mālama ʻia. Ke helu ʻoe i ka downtime, hana nalowale, a me ka hana, uku ka pā lole nona iho i loko o nā makahiki ʻelua.
Ua ʻike mākou i nā mea kanu e hoʻāʻo ana i nā pā kila kuhili ʻole—ua mihi lākou ma hope o ka pani mua ʻana. No ka desalination, E koho i ka mea hoʻopuka ʻo ASTM composite panel e hoʻomaopopo i ka lawelawe wai kai a ʻaʻole ʻoki i nā kihi o ka maikaʻi o ka pilina.
Pehea e hōʻoia ai i ka maikaʻi mai kahi mea kūʻai aku i ka panel composite ASTM
Mai ʻae wale i ka pepa kumu kūʻai. E nīnau i kēia mau nīnau:
- He aha ka nui o kāu pāpaʻi paʻa?
- Hiki iā ʻoe ke hāʻawi i nā scan UT no kēlā me kēia ʻīniha square?
- He aha kou ikaika shear maʻamau no ka titanium-steel?
- ʻO wai nā ʻoihana nānā ʻaoʻao ʻekolu āu e hana pū ai?
- He aha kāu manawa alakaʻi no kahi kauoha nui maʻamau?
Ua hana pū mākou me nā mea kūʻai aku nāna i hāʻawi i ke wikiō o ke kaʻina hana hoʻopaʻa pahū a kaʻana like i ka ʻikepili UT maka. He kakaikahi kēlā pae o ka hāmama, akā, he hōʻailona ia o ka hana maikaʻi.
I ka hopena o ka lā, ke koho ʻana i ka mea hoʻopuka panel composite ASTM kūpono no nā mea kanu desalination e iho mai i ka ʻike. E kamaʻilio me nā mea hoʻohana o nā mea kanu e kū nei. E nīnau i ka mea hoʻolako a lākou i hoʻohana ai a inā paʻa nā panela. A laila koho i ka mea hoʻopuka i loaʻa i nā pilikia like āu e kū nei i kēia lā.
Mea hoolako
ʻO Metal Plate 4U kahi mea hoʻolako pūʻulu metala composite honua & mea hana me ka ʻike nui i ka hāʻawi ʻana i ke kila kila kila kiʻekiʻe, nickel alloy, kila keleawe, a me nā pā kila titanium. Hoʻokuʻu aku ka hui i nā ʻāina he nui, e like me ka USA, Kanaka, ʻEulopa, UAE, ʻApelika Hema, etc. Ma ke ʻano he alakaʻi pahū i hoʻopaʻa ʻia i ka mea hoʻomohala pā, ʻO ka Metal Plate 4U ka luna o ka mākeke. Hāʻawi kā mākou hui hana ʻoihana i nā hāʻina kūpono e kōkua i ka hoʻomaikaʻi ʻana i ka pono o nā ʻoihana like ʻole, e like me na ipu kaomi, nā mea hoʻololi wela, hana moku, a me ka hana kemika, hana waiwai, a maʻalahi hoʻi i nā pilikia like ʻole. Inā ʻoe e ʻimi nei i nā panela metala composite a i ʻole nā papa lole bimetal, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou!
