Kino kila forged, kiʻekiʻe puʻe kinipōpō pōlele no ka aila, kinoea a me nā paipu kemika

Hele mai ia me nā hopena flange maʻamau. ʻO ia ke kumu e koho pinepine ai nā ʻenekinia a me nā luna mea kanu no nā laina koʻikoʻi kiʻekiʻe - he maʻalahi ke kau ʻana ma ka pūnaewele, maʻalahi ka mālama ʻana, a paʻa i ka hui flange kahi sila hilinaʻi.

Nā mea nui

Hana ʻia ke kino kila forged

Hoʻokumu ʻia ko mākou kino pōpō pōpō flanged i hana ʻia mai ka billet kila paʻa ma o ka hana ʻana, ʻaʻole ka hoʻolei ʻana i ke one. Hoʻomaʻemaʻe ke kaʻina hana forging i ke ʻano o ka palaoa i loko o ka metala, e hoʻopau ana i nā hemahema hoʻolei maʻamau e like me ka porosity, shrinkage cavities a me ke one inclusions. Hāʻawi kēia i ke kino valve kiʻekiʻe loa i ka ikaika tensile, ka pale ʻana i ka hopena a me ke kūpaʻa haʻalulu.

Hana maikaʻi nā pahu hoʻolei no nā paipu maʻamau, haʻahaʻa haʻahaʻa. Akā, no ke kiʻekiʻe-pressure, cyclic ukana a me ka palekana-koʻikoʻi lawelawe, forged construction drastically hōʻemi i ka pilikia o ke kino māwae a me ka catastrophic leakage. Hiki ke ʻimi ʻia kēlā me kēia hoʻoheheʻe maka me nā helu wela, a loaʻa nā palapala hōʻoia piha piha (MTC) ma ke noi.

ʻO wai nā ʻoihana a me nā mea hoʻolaha e kūpono i kēia pahu pōpō flanged forged?

Hoʻohana nui ʻia kēia flanged forged ball valve ma waena o ka aila a me ke kinoea, ka lawe ʻana i ke kinoea kūlohelohe, ka hoʻoili ʻana i nā kemika, nā refineries, ka hana mana, nā paipu kōkua ma waho o ke kai, nā ʻōnaehana wai wai kiʻekiʻe a me nā mea kanu mea kanu.

He hana hilinaʻi ia no nā wai maʻemaʻe, ka ea i hoʻopaʻa ʻia, ke kinoea maoli, ka nitrogen, ka hydrocarbon a me ka nui o nā wai kaʻina non-abrasive. Me ka ʻoki kūpono a me ke koho ʻana i nā mea noho, hiki iā ia ke mālama i ka media corrosive haʻahaʻa. Hoʻolālā ʻia ia no ka lawelawe kaʻawale, kūpono no nā pipeline e koi ana i ka pani ʻana i ka wā o ka mālama maʻamau a i ʻole ka pani ʻana i ka pilikia.

Hoʻolālā Hoʻohui Flanged

ʻO ka pilina Flanged ke koho maʻamau no nā papahana ʻoihana kaumaha. ʻO ke alo flange maʻamau (RF / RTJ koho) pili i nā kūlana flange ASME B16.5 a i ʻole GB. I ka wā o ka hoʻokomo ʻana, hiki i nā poʻe o ka pūnaewele ke hoʻoponopono maʻalahi i nā puka bolt, kau i nā gaskets a hoʻopaʻa i nā bolts me ka ʻole o nā lako wili kūikawā.

Loaʻa ka pōmaikaʻi nui i ka wā o ka overhaul: hiki iā ʻoe ke wehe koke i ka valve mai ka pipeline me ka ʻole o ka ʻoki ʻana i ka paipu. Hoʻokiʻoki loa kēia i ka manawa haʻahaʻa inā pono ʻoe e nānā i nā mea i loko, hoʻololi i nā noho a hoʻololi paha i ka valve holoʻokoʻa. Ke hoʻohālikelike ʻia me nā wēlau i hoʻopaʻa ʻia, kākoʻo nā hui flanged i nā pae kiʻekiʻe kiʻekiʻe; hoʻohālikelike ʻia me nā hopena welded, hiki iā ia ke hoʻokaʻawale hou.

Hiki anei i keia kiwi poepoe hana ke hooikaika i ka wela a me ke kowali pinepine?

ʻIke pinepine nā pipeline ʻoihana i ka neʻe ʻana o ke kaomi hana a me ka mahana i ka wā e hoʻomaka ai, pani ʻia a me nā loli. Mālama ke kino kila forged i ka hana mechanical paʻa ma lalo o kēia mau kūlana cyclic.

Hoʻohālikelike mākou i ka pūʻolo hoʻopaʻa i kāu envelop hana. PTFE, RPTFE a me metala-i-metala paʻakikī koho i loaʻa. Hāʻawi nā noho palupalu ʻole-leak bubble i pani paʻa no ka lawelawe maʻemaʻe; nā noho metala kūpono i ke kiʻekiʻe wela a i ʻole ke ahi-palekana koi. Hoʻolālā ka hoʻolālā packing stem i nā hoʻokuʻu mahuka, e hālāwai ana i nā koi kūlohelohe maʻamau no ka lawelawe hydrocarbon.

Nā Koho Mea no ke Kino & Kūloko

Mālama mākou i kahi waihona waiwai ākea e hoʻohālikelike i kāu koi ʻana i ka corrosion a me ka wela.

- Ke kila kalapona: A105 / A105N, kūpono no ke kinoea kiʻekiʻe-corrosive a me ka ʻaila.

- Austenitic stainless steel: F304, F316L, no ka wai corrosive maʻamau

- Duplex & super duplex: F51, F53, F57, NS2609, NS2607 no ka wai kai, brine a me ka waiʻawaʻawa i loaʻa iā H₂S

Hiki iā mākou ke hana i nā mea pōpō, nā kumu a me nā mea noho. E kaʻana like i kāu mea waena, ka waiwai pH a me ka pae wela o ka hana, a na kā mākou hui ʻenekinia e paipai i ka hui ʻoki ʻoi loa.

Nui, Papa Paʻi & Hoʻolālā koho

Uhi nā nui iā DN15 ~ DN300 a ʻoi aku ka nui ma ke noi. Loaʻa i nā helu kaomi ka PN16, PN40, PN63, PN100, PN160, a me ka papa ASME 150, 300, 600, 900, 1500.

Loaʻa nā maka Flange ma Raised Face (RF) a me Ring Type Joint (RTJ). Hiki ke hāʻawi ʻia nā hoʻolālā pale ahi a me nā mea hoʻolālā anti-static ma ke noi.

Hiki iā ʻoe ke koho i ka ʻōpū piha a i ʻole ka hōʻemi ʻia. ʻOki ʻoki piha ʻana i ke kahe kahe a hiki i ka puaʻa. ʻOi aku ka liʻiliʻi a ʻoi aku ka maikaʻi o ke kālā inā ʻaʻole pono ka puaʻa.

Nā koho hana

Hāʻawi mākou i kekahi mau ʻano hana e kūpono i kāu pono pūnaewele:

- Lever lima: hiki ke maʻalahi a maʻalahi, kūpono no ka hana lima ke maʻalahi ke kiʻi

- Mea hoʻohana Gear: no nā ʻūhā nui a i ʻole kiʻekiʻe-torque valve, ʻoi aku ka maʻalahi o ka wehe ʻana a me ka pani ʻana

- Pneumatic actuator: wehe wikiwiki a kokoke. Hoʻopili ʻo ia me nā kiwi solenoid a me nā hoʻololi palena no ka mana ʻakomi

- Mea hana uila: kūpono no ka hana mamao, hoʻoponopono kahe, a i ʻole nā ​​​​wahi me ka hāʻawi ʻole ʻana i ka ea

Hiki iā mākou ke hoʻohui i kahi override lima lima i nā valve i hana ʻia. ʻAe kēia iā ʻoe e hana lima me ka lima inā pau ka mana a i ʻole ka hāʻawi ʻana i ka ea.

He aha nā kūlana nānā a me nā palapala hiki iā ʻoe ke loaʻa mai iā mākou?

E ho'āʻo ʻia ka hoʻāʻo hydrostatic shell a me ka leakage o ka noho ma mua o ka hoʻopaʻa ʻana. Ke hahai nei mākou i ka API 6D, ASME B16.5 a me nā kūlana ʻoihana pili. Kākoʻo ʻia ka nānā ʻana i nā mea hōʻike ʻekolu inā koi ʻia e kāu kikoʻī papahana.

Hiki iā mākou ke hāʻawi i nā pepa a pau āu e makemake ai: nā palapala hōʻike hōʻike waiwai, nā hōʻike hōʻike, nā kaha kiʻi a me nā manual hana. Hoʻopaʻa ʻia kēlā me kēia valve me kāna helu wela, ka pae waiwai, ka nui a me ka helu kaomi, no laila hiki iā ʻoe ke ʻimi i kāna moʻolelo a me ka mōʻaukala hana me ka pilikia ʻole.
