He paipa rino noa te paipa pango, kāore he paninga tiaki. He maha ngā whakamahinga o te paipa pango i te kāinga. He mea noa te kite i te paipa pango e whakamahia ana mō tō raina hau māori me ngā raina pūnaha tauhiuhi. Nā te mea kāore he paninga tiaki o te paipa pango, ka waikura ngāwari pea i ngā taiao maku, haumākū rānei. Hei ārai i te waikura, i te pirau rānei o waho o te paipa, me whakatakoto he paparanga tiaki ki waho o te paipa. Ko te tikanga māmā ko te peita.
ĀE. He kaha tā mātou mahi tahi me SINOSURE
Ko te tikanga o te RHS ko te Rectangular Hollow Section, arā, he paipa maitai tapawhā rite.
Kei a mātou anō hoki ngā paipa maitai tapawhā tuwhera, e ai ki ngā paerewa: ASTM A500, EN10219, JIS G3466, GB/T6728, he paipa maitai tapawhā matao, tapawhā tapawhā hoki.
Paipa maitai ERW, paipa maitai SSAW, paipa maitai LSAW, paipa maitai piauau, paipa maitai kowiri tira, paipa anga me te ngongo, tuke, whakaiti, tī, potae, hononga, flange, weldolet, Paipa maitai tui
TT, L/C (Mō te ota nui, ka taea te whakaae ki ngā rā 30-90).
Ka wehea ngā paipa maitai piauau ki ngā paipa maitai piauau tuku-matao me ngā paipa maitai piauau tuku-wera. Ko ngā paipa piauau e whakamahia ana mō te wai, te hau, te hinu me ētahi atu paipa wai pēhanga teitei noa. Ka whakamahia hoki ēnei i roto i te umanga hinu, inā koa ngā paipa mara hinu i ngā mara hinu o tai, ngā pouaka whakamatao, ngā paipa whakawhiti mamaoa waro me ngā puranga paipa piriti, ngā paipa tautoko maina, me ētahi atu.
E kīia ana ko ngā paipa rino kua whakapūmautia te whakamahinga mō te hau me te whakamahana. Hei paipa wai, ka kitea he waikura iti i muri i ētahi tau. Ehara i te mea ka poke noa i ngā taputapu horoi, engari ka tipu hoki ngā huakita ki te pakitara o roto o te paipa. Ka nui te konganuku i roto i te waikura, ā, ka whakararu i te hauora o te tangata.
Ko te whakapūmau wera he tuku i te paipa maitai ki roto i te waikawa hei horoi, ā, ka whakarite i te wairewa wai me te wairewa wai o te haukinia pūhaumāota, te konutea pūhaumāota me te konutea pūhaumāota rānei, ka ringihia ki roto i te awaawa. He ōrite te paninga whakapūmau wera, he piri kaha, he roa te ora mahi. He otinga whakakikoruatanga hiko matatini te hanganga o te paipa maitai whakapūmau wera, ā, he wairewa whakarewa, nō reira ka hangaia he whakatakotoranga kiato me te ātete ki te waikura. Ka honoa te paparanga koranu ki te paparanga konutea parakore me te turanga paipa maitai, nō reira he ātete ki te waikura kaha.
He paipa whakarewa matao he paipa whakarewa hiko, ā, he rerekētanga nui i waenga i te ātete waikura me te paipa whakarewa wera-tuku. Hei whakarite i te kounga, ko te nuinga o ngā kaihanga whakahaere whakarewa ōkawa kāore e whakamahi i te whakarewa hiko (whakakikorua matao). Ka whakamahia e aua umanga iti kore ōkawa te whakarewa hiko nā te mea he iti te utu. Ko te paparanga whakarewa o te paipa maitai whakarewa matao-tuku he paninga. Ka whakarārangihia motuhake te paparanga konutea ki te anga paipa maitai. He angiangi te paparanga konutea, ka hono noa ki te paipa maitai, ā, he ngāwari ki te taka. Nō reira, he ngoikore tōna ātete waikura. Nō reira, mō ētahi paipa tanumia tika, ka whakamahia tonutia ngā paipa maitai pepa rino whakarewa i hangaia e ngā kaihanga noa.
Me pēhea te tango i ngā paipa maitai kua waikurahia?
Tuatahi, pania te whakarewa ki waho o te maitai hei tango i ngā mea rauropi. Ka taea hoki te tango i te waikura mā te whakapūkara i muri i te paraihe, te ārai waikura, te horoi, te rino rānei, te waikura, te whakarewa para, me ētahi atu. Ka wehea te whakapūkara ki te paninga werawera me te paninga matao. Kāore e ngāwari te waikura o te paninga werawera, ā, he ngāwari te waikura o te paninga matao.
Ko ngā paipa wai ahi o nāianei he paipa piauau, ā, ko te paparanga o waho o te paipa piauau ka pania ki te paparanga peita. Ka kitea te paipa ahi he piauau. I roto i te hanganga maitai, he wāhi anō hoki tō te hangarau whakarewa. Nō reira, mā te whakamahi pinepine i ngā paipa maitai piauau ka ārai i te waikura mō te wā roa.

Ka kiia he rino koranu te ranunga ina nui ake te konupūmā i te 1.65%, ina neke atu te silicon i te 0.5%, ina neke atu te parahi i te 0.6%, ina iti rawa rānei ngā huānga koranu pērā i te chromium, te nickel, te molybdenum, te tungsten rānei. He tini ngā āhuatanga motuhake ka taea te hanga mō te maitai mā te whakakapi i ēnei huānga ki te tunu.
He tukanga hei whakapai ake i te maitai kore waikura mā te whakaiti i te ihirangi waro
Me iti iho te nui o te waro i roto i te maitai kore waikura i tērā i roto i te maitai waro, i te maitai koranu iti iho rānei (arā, te maitai he iti iho i te 5%) te ihirangi huānga koranu. Ahakoa ko ngā oumu pewa hiko (EAF) te tikanga tuku iho mō te whakarewa me te whakamahine i te maitai kore waikura, he tāpiringa ōhanga te AOD, nā te mea he poto ake te wā mahi, ā, he iti iho ngā pāmahana i tērā i roto i te hanga maitai EAF. Hei tāpiri, mā te whakamahi i te AOD mō te whakamahine i te maitai kore waikura ka nui ake te wātea o te EAF mō ngā kaupapa whakarewa.
Ka whakawhitia te rino rewa, kāore anō kia whakamātauria mai i te EAF ki tētahi oko motuhake. Ka pupuhihia he ranunga o te argon me te hāora mai i raro i te oko mā roto i te rino rewa. Ka tāpirihia ngā kai horoi ki te oko me ēnei hau hei whakakore i ngā poke, i te wā e honoa ana te hāora ki te waro i roto i te rino kāore anō kia whakamātauria hei whakaiti i te taumata waro. Mā te noho mai o te argon ka whakanui ake i te kaha o te waro ki te hāora, ā, ka āwhina i te tango i te waro.
He tukanga hikohiko te waikura o te maitai hanganga e hiahia ana kia noho tahi te makuku me te hāora. Mēnā kāore tētahi o ēnei, kāore e puta te waikura. Ko te tikanga, ka waikurahia te rino i roto i te maitai hei whakaputa waikura, e ono ngā wā te nui o te waikura i roto i te rauemi taketake i pau i roto i te tukanga. Kei konei te whakaaturanga o te tukanga waikura whānui. Haunga te waikura whānui, he maha ngā momo waikura ā-rohe ka puta; te waikura bimetallic, te waikura pitting me te waikura crevice. Heoi, kāore ēnei i te tino hira mō te mahi maitai hanganga. Ko te tere o te whanaketanga o te tukanga waikura e whakawhirinaki ana ki ētahi āhuatanga e pā ana ki te 'āhuarangi iti' e karapoti ana i te hanganga, ko te nuinga ko te wā makuku me te taumata parahanga o te hau. Nā te rerekētanga o ngā taiao hau, kāore e taea te whakawhanui i ngā raraunga tere waikura. Heoi, ka taea te whakarōpū whānui i ngā taiao, ā, ko ngā tere waikura maitai i inehia e rite ana he tohu whai hua mō ngā tere waikura pea. Kei roto i te BS EN ISO 12944-2 me te BS EN ISO 9223 ētahi atu kōrero.
Kua peitahiaSHS (ngā wāhanga tapawha tuwhera)me te RHS (ngā wāhanga takoto kau tapawhā rite) he wāhanga maitai takoto kau kaha, he mea hanga matao, kua pania ki te peita tuatahi hei tiaki i te wā e rokiroki ana, e whakahaere ana hoki.
Hua ahua mō te paipa maitai tapawhā whakarewa wera
E ai ki te American Galvanizers Association, mēnā ka roa te wā e whakamahia ana, ko te pāmahana mōrahi e taunakitia ana mō te maitai whakarewa wera-tuku ko te 200 °C (392 °F). Mā te whakamahinga o te maitai whakarewa i ngā pāmahana kei runga ake i tēnei ka puta te kiri o te konutea i te paparanga whakarewa.
Ko tōna tikanga he wāhanga tapawha tuwhera e whakarapopototia ana ko SHS.
Ko tōna tikanga he wāhanga porowhita tuwhera, e whakarapopototia ana ko SHS.
