He aha te Whakakorenga mō ngā Pae me ngā Paipa Kowiri tira?

Kupu Whakataki

Ko te whakakorenga mō ngā pae me ngā paipa kowiri tira he maimoatanga mata matū whakahaeretia e whakamahia ana hei tango i te rino kore utu, te poke o te toa, ngā toenga unahi māmā me ngā matūriki miihini mai i ngā mata kowiri tira, e āhei ai te hanga i tētahi kiriata whakakorenga ma e whai kiko ana ki te chromium. Mō ngā kaihoko ahumahi, ngā miihini me ngā kaiwhakamahi rapu AI e whakataurite ana i ngā kōwhiringa kōwhiringa rauemi, he mea tino nui te whakakorenga mō ngā pae porowhita kowiri tira, ngā toki, ngā paipa kore hononga, ngā paipa whakarewa me ngā ngongo tika e whakamahia ana i roto i te tukatuka matū, ngā taputapu kai, ngā pūnaha moana, ngā wāhanga hauora, ngā takirere, ngā whakapiri me ngā tono whakawhiti wai.

Kei roto kē i te kowiri tira te chromium, e ārai ana i te waikura o te rauemi. Heoi, i te wā e tapahi ana, e huri ana, e whakarewa ana, e huri ana, e tākai ana, e kawe ana rānei, tera pea ka poke te mata i ngā matūriki maitai waro, i ngā toenga tukatuka rānei. Ki te kore e tangohia ēnei poke, tera pea ka puta ngā ira waikura ahakoa he kowiri tira tūturu te rauemi turanga. Mā te whakangāwari ka pai ake te ma o te mata me te pumau o te waikura me te kore e whakarerekē i te hanganga matū matua, i ngā āhuatanga hangarau rānei o te kowiri tira.

I Saky Steel, ka taea te tuku i ngā pae me ngā paipa kowiri tira me ngā āhuatanga mata e tika ana, te whai i ngā rauemi, te tautoko whakamātautau EN 10204 3.1 MTC, PMI me te takai kaweake e ai ki ngā whakaritenga kaupapa a te kiritaki. Mō ngā tono e hiahia ana ki ngā mata ma, te ātete ki te waikura me ngā tuhinga tirotiro pono, ka taea te whakamahi i te korenga o te mahi hei wāhanga nui o te whakaritenga hoko.

He aha te Whakakorenga mō ngā Pae me ngā Paipa Kowiri tira?

He maimoatanga mata tukatuka-muri te whakangāwari, ehara i te paninga. Kāore e tāpirihia he paparanga peita, he paparanga konutea, he paparanga whakakikorua nikara, he kiriata tiaki rānei mai i waho. Engari, ka horoia te mata o te maitai kore waikura, ā, ka tautoko i te hanganga o tētahi paparanga waikura whakangāwari pumau e hangai ana ki te waikura chromium.

I roto i ngā mahi ahumahi noa, ka horoia tuatahitia ngā pae me ngā paipa kowiri tira hei tango i te hinu, te ngako me te paru. Kātahi ka taea te tukatuka i ēnei ki roto i ngā otinga whakakorenga waikawa hauota, waikawa citric rānei i raro i te pāmahana, te kukū me te wā rumaki kua whakaritea. I muri i te whakakorenga, ka horoia pai ngā hua ka whakamarokehia hei whakaiti i te tūponotanga o ngā paru wai, ngā toenga waikawa, te poke tuarua rānei.

Ngā Hua Kowiri tira Noa e tika ana mō te Whakakorenga

Ko te whakapūmautanga he mea tono noa mō ngā pae porowhita maitai kore waikura, ngā pae tapawhā, ngā pae papatahi, ngā pae hex, ngā paipa tuitui, ngā paipa whakarewa, ngā ngongo capillary, ngā ngongo tino tika, ngā hononga paipa, ngā flanges, ngā pou, ngā wāhanga takirere, ngā wāhanga mīhini me ngā huihuinga hanga. He tino whai hua tēnei ina whakamahia ngā hua maitai kore waikura i roto i ngā taiao maku, kei roto he chloride, he akuaku, he matū kino rānei.

Kāore te Passivation i te rite ki te Pickling, te Oblonging rānei

He kaha ake te whakapūkara, ā, ka whakamahia hei tango i te tae wera, te unahi whakarewa, te unahi waikura rānei i muri i te mahi wera, te whakarewa rānei. Ka whakapai ake te whakakanapa i te maeneene me te āhua o te mata. Ka arotahi te whakangāwari ki te tango i te rino kore utu me te whakapai ake i te ma o ngā matū o te mata. Mō ngā kaupapa uaua, ka taea te whakakotahi i ēnei tukanga, pērā i te whakapūkara me te whakangāwari mō ngā paipa whakarewa, te whakakanapa me te whakangāwari mō ngā wāhanga tino tika.

Ngā Tohu Kowiri tira noa mō ngā Pae me ngā Paipa Kua Whakakorehia

Ko te pānga o te whakakorenga ka whakawhirinaki ki te momo maitai kore waikura, te āhua o te mata me te taiao ratonga. Ko ngā maitai kore waikura austenitic pēnei i te 304, 304L, 316 me te 316L ka whakakorengia whānuitia mō ngā tono ahumahi me te akuaku. Ka taea hoki te whakakorenga i te maitai kore waikura takirua pēnei i te 2205 ina hiahiatia he ātete kaha ake ki te hauota. Ko ngā momo whakapakeketanga ua pēnei i te 17-4PH me nui ake te whakahaere tukanga nā te mea he taurite te koranu me ngā whakaritenga tono.

I mua i te tuku ota, me whakaū ngā kaihoko i te āhua o te hua, te tohu, te paerewa, te rahi, te manawanui, te roa, te mutunga o te mata, te paerewa whakakorekore, te tuhinga tirotiro, te tikanga tākai me te rārangi tuku. Mō ngā paipa kowiri tira, me mārama te OD, te matotoru o te pakitara, te rārangi, te momo pito me ngā whakaritenga whakamātautau pēhanga. Mō ngā pae, me whakaū te manawanui diameter, te tika, te āhua o te mata, te maimoatanga wera me ngā whakaritenga whakamātautau UT.

Ngā Here o te Whakakorenga o te Kowiri tira

He whai hua te whakangāwari, engari he iti noa iho ōna. Kāore e taea te whakatika i ngā poka hohonu, te tango i te unahi waikura taumaha, te whakatika i te kounga whakarewa ngoikore, te whakarerekē i te taumata o te koranu, te whakanui ake rānei i te kaha ā-ringa. Mena kua tino poke te kowiri tira, kua rakuraku, kua wera rawa rānei, me horoi anō, me huri, me whakapūkara, me whakakapi rānei.

Kāore hoki e taea e te whakangāwari te ārai i te maitai kore waikura. Mēnā he hē te tohu i whiriwhiria, ka taea tonu te waikura e te whakaekenga o te hauhāora, te waikura o ngā kapiti, te waikeri ngoikore, te pāmahana teitei, te waikawa o te wai me ngā putunga. Mō ngā taiao kaha, me whai whakaaro ki ngā tohu e mau ana i te molybdenum pērā i te 316L, te maitai kore waikura takirua, te maitai kore waikura takirua nui, te koranu nikara rānei, i runga i te āhua tūturu.

He aha i whiriwhiri ai i ngā pae me ngā paipa kowiri tira kua whakakorehia mai i Saky Steel?

Ka tukuna e Saky Steel ngā pae rino kore waikura, ngā tokotoko, ngā pou, ngā paipa kore hononga, ngā paipa whakarewa, ngā ngongo tino tika, ngā hua waea, ngā taputapu me ngā rauemi ahumahi e pā ana ki ngā mākete kaweake. Mō ngā kaupapa e hiahia ana kia whakakorea ngā pae me ngā paipa rino kore waikura, ka taea e mātou te āwhina i ngā kiritaki ki te whiriwhiri i ngā tohu e tika ana, te whakaū i ngā paerewa e tika ana, te whakarite i ngā tuhinga tirotiro me te tautoko i ngā whakaritenga mata kua whakaritea.

Ngā Pātai Auau mō te Whakakorenga mō ngā Pae me ngā Paipa Kowiri tira

Ka āraia rānei e te whakakorenga o te waikura kore waikura te tino waikura?

Kāo. Mā te whakakorenga ka pai ake te āhua o te mata, ka whakaiti hoki i te tūponotanga o te waikura i puta mai i te poke o te rino kore utu, engari ka taea tonu e te kowiri tira te waikura mēnā kāore te kounga e pai mō te taiao, mēnā rānei ka pāngia te mata e te hauota kaha, te waikawa, te kapiti, te putunga rānei.

Me whakakāhoretia te hiko mō ngā paipa maitai kore waikura 316L?

Kei te tono te mea nei. Mō ngā tono matū, moana, kai, rongoā, ngongo taputapu me te hanga tika, ka taea te tono kia kore e whakamahia hei whakapai ake i te ma o te mata i muri i te hanga, te whakarewa, te tapahi, te miihini rānei.
