Mō ngā kaimahi hinu me te hau, ko ngā rauemi whakarewa tiaki katote ngā mea e pau ana hei hono i ngā taura whakamātautau, ngā taura anode me ngā ara iahiko hono ki tētahi paipa tanumia — ā, ko te whakatau hoko e ahu mai ana i ngā mea e toru: he paura whakarewa wera e ōrite ana ki te rauemi me te rahi o tō ara iahiko, he pokepokea karāhe e ora ana i ngā hononga 80–100, me tētahi kaiwhakarato e ora ana tana tākai me āna pepa i te tirotiro kaweake. Kei roto ahau i te wheketere e hanga ana i ēnei rauemi, ā, i roto i tēnei aratohu ka whakamāramahia e au ngā mea e whakaranua ana e mātou, ngā mea e tawhito ana, ngā paerewa ka whakahuatia e tō rōpū QC (AMPP/NACE SP0169, ISO 15589-2:2024, IEEE 837), me te pāngarau paunga me whakahaere e koe i mua i te tuku i tētahi ota hoko.

Mai i ngā Pānga Āwhata ki ngā Herenga Ngota: He aha i Whakapūmau tonu ai ngā Kaimahi CP i te Wera Wera o ngā Paipa?

Ko te whakautu poto: nā te mea ko te pono o te pūnaha tiaki katote (CP) — te whakamahinga hangarau o ngā anode iahiko tika, ngā anode patunga tapu rānei hei pupuri i te paipa maitai kua tanumia ki te pūmanawa ka iti haere te waikura — ka rite anake ki te pono o ōna hononga.Nā te mea me noho tonu te taura whakamātautau, te taura anode me te waea here ki te hiko tonu mō te roanga o te hoahoa o te paipa, ka tohua e ngā kaihangarau he hononga ngota, kaua he hononga miihini.Ko te whakarewa werawera, e tuhia ana hoki ko te whakarewa werawera, ā, e mōhiotia ana i te ao whānui ko te kupu hokohoko CAD weld (mai i te waitohu Cadweld), ka honoa te ara iahiko ki te mata o te paipa i roto i te pokepokea ai te karāhe mā te whakamahi i te parahi rewa i hangaia e te tauhohenga paura. Kāore he rawhi hei wetewete, kāore he hononga whakarewa hei ngokingoki, ā, kāore he whiunga pewa ki te pakitara o te paipa.

Tekau mā rua tau ahau e mātakitaki ana i tēnei mahi mai i te taha tuku. Ina huri te kaihanga paipa mai i ngā hononga ā-ringa ki ngā hononga werawera, he iti, he tupato te nuinga o te wā ka puta te ota hoko tuatahi - kotahi te kapa, kotahi te horapa. He nui ake te ota tuarua.Nā te mea kāore e hiahiatia he mīhini whakarewa, he mīhini whakarewa, he kaimahi whakarewa whai raihana hoki ki te awaawa, ka pupuri tonu ngā kaimahi i ngā reiti whakaputa ahakoa i ngā wāhanga tawhiti e kore e taea te kawe i ngā taputapu whakarewa pewa.E whakamārama tika ana te tuhinga hua a tō mātou wheketere: he iti te utu, he ngāwari te kawe, ā, he ngāwari te whakahaere me te kore he pūkenga motuhake. Ehara tēnā i te reo hokohoko; koinei te take i nekehia ai e te tikanga ngā hononga miihini puta noa i te whenua me te mahi CP i ngā tekau tau e rua kua pahure ake nei.

Ngā Rauemi Whakarewa Parenga Katorika: He aha kei roto i te BOM a te Kaimahi?

He nui ake ngā tūemi raina o tētahi rārangi rauemi mō ngā hononga CP exothermic i tā te nuinga o ngā kaihoko tuatahi e whakaaro nei. I runga i tā mātou papa whakaputa, ka taea e au te mātakitaki i tētahi huinga kua rite mō te tuku: tepaura whakarewa weratonu, te pokepokea ai te hononga, he pū mura ahi, he kōpae whakarewa e hiri ana i te rūma paura kia tīmata rā anō te tauhohenga, he rawhi whakamau, he karapu ātete wera, me ngā paraihe horoi. Ki te ngaro tētahi o ēnei, ka mahi auaha tō tira i te awaawa.

E toru ngā wāhanga e tika ana kia arohia e te kaihoko nā te mea ko ēnei te mea e whakatau ana i te kounga o te hononga:

• Paura whakarewa Thermit.Ko tā mātou paura whakarewa werawera he ranunga waikura parahi me te konumohe — ka whakaitihia e te tauhohenga te waikura parahi ki te parahi rewa i ngā pāmahana teitei hei whakakotahi i ngā ara iahiko parahi ki te paipa maitai. Ko te mea nui ko te ōwehenga: ka whakaranua e mātou te paura kia rite ki te rauemi me te wāhanga whakawhiti o tō ara iahiko,Nā te mea ka waiho he hononga kāore i oti i te utu iti, engari ka pupuhi te konganuku i roto i te pokepokea ai, ā, ka maumauria ngā rauemi i ia hononga..
• Te rerenga whakarewa werame ngā rauemi tīmatanga.Mā te rere ka noho ma te tauhohenga, ā, ka āwhina i te parahi rewa kia mākū te mata o te paipa; i ngā ata haukū, i ngā maitai rānei kāore i te pai te horoi, mā te rere ka tiaki i te hononga mai i te porousness.
• Te pokepokea ai te karāpeti.Koinei te wāhanga tino tika. Ka hiritia e te pokepokea karāhe kua oti pai te mīhini te hanga i te ara iahiko me te paipa, ā, e whakaatu ana ā mātou ake rekoata wheketere he roa te ora o ia pokepokea he 80–100 hononga — he roa ake i te nuinga o ngā pokepokea whakataetae kua whakaritea e ā mātou kiritaki. Ka turuturu te parahi rewa i te pokepokea kua tawhito, ā, ka puta he hononga i te pokepokea e turuturu ana ka whakakahoretia e tō kaitirotiro.

Paura whakarewa wera SHIBANG: he ranunga waikura parahi me te konumohe, he mea pounamu hei whakamahi mā te mara i runga i ngā hononga tiaki katote o ngā paipa.

Te Whakarewa Wera o ngā Paipa i roto i te Waikeri: Me Pēhea te Tuturutanga o te Tukanga i raro i ngā Rā Katinga?

I runga i te horapa ora, onge noa te herenga ko te whakarewa tonu — engari ko te kapa paninga kei muri i a koe. He meneti te roa o te hononga werawera: horoia te mata o te paipa me te ara iahiko ki te konganuku kanapa, whakanohohia te pokepokea ai, tukua te kōpae konganuku ki roto, whakakīia te paura, tahuna ki te pū kiripaka, tatari mō te tauhohenga, wahia te pokepokea ai, ka horoia te hononga mō te taputapu paninga. I whakaahuahia e mātou tā mātou raupapa mara e waru-taahiraa ki runga i ngā hononga tuturu, ā, ka rere mai i te whakarite mata tae noa ki te hononga kua oti, kua rite ki te tirotiro.

Ngā tuhi raupapatanga mara me ngā hononga mō ngā hononga whakarewa CAD: te whakarite mata, te nohoanga pokepokea ai, te mura, me ngā hononga kua oti te whakarite mō te paninga.

E ai ki taku e kite nei i ngā ota whakahoki, he pono te pumau o te tukanga ki te āheinga whakahoki. Kia oti te mahi a te kapa i ngā hononga tekau mā rua, ko ngā momo rahunga he mea whakarite tonu, ehara i te mea rauemi: he makuku i roto i te pokepokea ai, he hinu, he hinu rānei i runga i te paipa, he pokepokea ai rānei kua roa e whakamahia ana.Nā te mea ka wera, ka pakaru hoki ngā hononga i te konganuku rewa wera e tauhiuhia ana e te wai, e te hinu rānei, e tohe ana ā mātou tuhinga mō te tākai kia maroke te rokiroki me ngā mata ma, maroke hoki — ā, ka whakahuatia anō e au taua whakatūpato i roto i ia nama proforma ka tukuna e au.Mena kei te mahi tō rōpū i roto i ngā kohu mura, i te puehu rānei, kati; he āhuatanga ahi, he pahūtanga tēnā, ehara i te āhuatanga kounga.

Tirohia ngā āhuatanga i mua i tō whakamahinga Puna: Ko ēhea paerewa e whakahaere ana i ngā hononga wera-ā-roto i runga i ngā paipa?

Ko tāu kōnae QC, ehara i te rārangi ingoa a te kaiwhakarato, e whakatau ana i te tikanga o te kupu "e whakaaetia ana". I roto i ngā mōkihi hoko e arotakehia ana e au, e whā ngā tohutoro e puta ake ana i ia wā, i ia wā:

• AMPP / NACE SP0169, Ko te Whakahaere i te Waikura o Waho i runga i ngā Pūnaha Paipa Whakarewa o raro whenua, o raro rānei i te wai, koinei te paerewa matua ka whakahuatia e tō kaihangarau waikura mō ngā paearu pūnaha CP me ngā mahi tāutanga i runga i ngā paipa tanumia.
• ISO 15589-2:2024, te putanga tuatoru o nāianei mō te tiakitanga katorika o ngā paipa taiwhenua, e whakahaere ana i te hoahoa, ngā rauemi, te tāutanga, te whakatinanatanga me te tiaki i ngā pūnaha CP mō ngā paipa me ngā ara piki i raro i te wai.
• IEEE 837, Ko te Paerewa mō ngā Hononga Tuturu Whai Mana e Whakamahia ana i roto i te Whakatakotoranga Whenua o te Teihana Irirangi, koinei te anga tohu e whakamahia ana ina hiahia te kaihoko ki te taunakitanga he pumau te momo hononga werawera i raro i te hapa me te ahotea taiao — ahakoa i runga i ngā mahi paipa, ko tōna arorau whakamātautau (te huringa o nāianei, te huka-rewa, ngā raupapatanga waikura) e mōhiotia ana e ngā kaitirotiro tohutoro.
• Mō ngā paipa wai e whakahaeretia ana e te US,49 CFR Wāhanga 195(PHMSA) e whakarite ana i te whakahaere waikura o waho — tae atu ki te tiakitanga katote — hei herenga ture, koia te take ka mutu ai ngā tuhinga hononga ki roto i ngā kōnae arotake.

Kotahi te herenga pono: ka taea e te kaiwhakarato paura-me-te-pokepokea te tuhi i te hanganga rauemi, te aromatawai a te hunga tuatoru (ka aromatawaihia ā mātou hua e CEPRI, te China Electric Power Research Institute) me te tākai - engari ko te tohu taumata-hononga ka puta i tō taha, me ō kaiārahi me ō kaitirotiro. Ka kī atu ahau ki ia kiritaki kirimana hou i te mea kotahi: tonoa he rahinga whakamātautau i te tuatahi, whakarewahia ō hononga whakamātautau ake, ā, tukua tō kaitirotiro kia tapahi i ētahi. Ko tetahi wheketere e kore e whakaae ki taua taahiraa he kōrero ki a koe i tetahi mea.

Te Pāngarau Hoko Kāore he Tānga: He aha te pānga o te roa o te pokepokea ai me te paura ki te utu tuturu?

Koinei te wāhi e whakarerekē ai ā mātou raraunga wheketere i te whakatau hoko. Kotahi te utunga ka tukuna mō ia hononga, engari i roto i ā mātou tuhinga tuku ka pau ngā pokepokea i runga i te piko - ā, ko taua piko te wāhi e turuturu ai ngā tahua. Ko te roanga o te ora ratonga kua tuhia mō tētahi pokepokea kounga teitei he 80–100 hononga; he maha ngā wā ka pakaru, ka turuturu rānei ngā pokepokea e whakaaturia mai ana e ngā kaihanga pokepokea mai i ngā kaiwhakarato o mua i mua noa atu.Nā te mea ka moumou te paura, te kōpae, te wā o te kapa, me te pito hiko o te pūwero i te pakaru o te pokepokea, he maha ngā wā ka nui ake te utu o te pokepokea iti ake te utu — ka heke te utu katoa mō ia hononga kua oti i te pikinga o te roa o te pokepokea, ahakoa he teitei ake te utu mō ia pokepokea.Kāore au e tā i ngā tatauranga tāra ki konei, nā te mea ka nui rawa ngā tau tūturu e nekehia ana e ngā tikanga utanga, te rahinga o ngā ota me tō tauranga tukunga mō tētahi utu kotahi pono; ko te hanganga o te pāngarau ka taea e au te tā.

Whakahaerehia ō ake tau mā te whakamahi i te tātai i raro nei — ka whakamahia ā mātou tau kua tuhia ki te wheketere (80–100 hononga mō ia pokepokea ai; tākai kaweake o ngā wahi 10 mō ia pouaka me ngā pouaka 10 mō ia kātene) me tō tatau hononga. Kāore he moni e hiahiatia ana; ko te kaupapa ko te rahi i te ota, me te wāhi tono anō, i roto i ngā waeine ā-tinana i te tuatahi.

Te Arotake i tētahi Kaiwhakarato Rauemi Thermit: E Ono Ngā Pātai e Wehewehe Ana i ngā Wheketere mai i ngā Kaihoko Anō

Ko te nuinga o ngā mamae e kitea ana e au i tēnei mahi hokohoko i ahu mai i te hoko mai i roto i ngā paparanga o ngā kaihoko kāore e taea te whakautu i ngā pātai hangarau. Ahakoa ka hoko mai koe i a mātou, kāore rānei, e whakaatu ana ēnei pātai e ono ko wai te kaihanga o te hua:

1. Ka taea e koe te whakaatu i te whakatakotoranga paura e ōrite ana ki te rauemi me te rahi o taku ara iahiko, me te whakamārama mai hoki i te ōwehenga whakaranu ka whakamahia e koe mōna?
2. Kia pēhea te roa o te ora o te pokepokea ai te karāhe kua tuhia mō ngā hononga whakarewa, ā, he aha ngā tikanga whakahaere, rokiroki rānei e pā ana ki taua tatauranga?
3. Ko tēhea whakahaere motuhake kua aromatawai i ō rauemi whakarewa — ki a mātou ko te whakautu ko CEPRI — ā, ka taea e koe te tuku mai i te tohutoro aromatawai?
4. Me pēhea te tākai i te paura me ngā pokepokea mō ngā utanga moana — 10 ngā wahi o tā mātou mō ia pouaka, 10 ngā pouaka mō ia kātene — ā, nō tēhea tauranga koe e tuku ai?
5. He aha te kaha tuku o ia marama ka taea e koe te tuku mā te tuhituhi — e 100,000 ngā wahi o tā mātou raina i ia marama — ā, he aha te roa o tō wā arahi i te wā tino pīrahi?
6. Ka tukuna atu e koe te huinga taputapu katoa (pū kiripaka, here, karapu, paraihe) me ngā tuhipoka haumaru tuhituhi me te ota tuatahi, kāore rānei he tūemi tāpiri?

Ki taku wheako, ka whakautua ēnei e te wheketere mā te īmēra kotahi, ko te kaihoko ia ka tuku atu, ka hoki mai anō i muri i ngā rā e toru me ngā whakapae.Nā te mea he taonga pau e tata ana ki te haumaru ngā rauemi whakarewa tiaki katote i runga i ngā hanganga kua whakaritea, ehara te utu mō te whakautu hē i te whakahokinga moni — engari he horapa kua whakakahoretia, ā, he kapa kua nekehia anō.

Te Tuhituhi, te Tākai, me te Wā Arataki: Kei hea te nuinga o te wā ka hē ai ngā ota kawemai?

I muri i te tekau mā rua tau o te kaweake i ngā hua whenua me ngā hua exothermic, ka taea e au te kī atu he hoha ngā hapa e kitea ana e mātou - ā, ki taku whakaaro he rongo pai tēnā, nā te mea ka taea te ārai i ngā hapa hoha. E mōhio ana mātou ka mimiti te paura i te makuku, nō reira ka hiritia e mātou ia pounamu i mua i te wehenga atu i tā mātou raina, ā, me ora ngā kātene i te haerenga ipu makuku; he pakarukaru ngā pokepoke, nō reira me wehe me te whakamarumaru i roto i te kātene; ā, ka whakarite mātou kia whakaingoatia ngā taonga e ā mātou pepa i roto i te huarahi e mōhiotia ana e tō kaihoko tikanga me te tari QC o tō kiritaki. Ka tukuna e mātou mai i Ningbo, i Shanghai rānei, ā, mō ngā kawemai tuatahi ka haere tahi mātou me te kaihoko i ngā tuhinga i mua i te rerenga o te kaipuke, kaua i muri i tōna taenga mai.

He pokepokea ai whakarewa werawera SHIBANG me te rawhi kakau me te pū mura kiripaka — he roa te ora 80–100 hononga mō ia pokepokea ai.

Ko tāku tohutohu whakamutunga ko te raupapatanga: te tono tuatahi mō te whakamātautau, te whakarewa me te wehewehe i ō hononga whakamātautau, kātahi ka whakawhāitihia ki ngā rahinga o te kaupapa me te tātai anō i te roa o te pokepoke kaua ki te whakaaro noa. Ki te hiahia koe ki tētahi atu tirohanga ki tō RFQ i mua i te tukunga atu ki tētahi atu — tae atu ki a mātou — tukua mai. He pai ake ki ahau te whakatika i tētahi whakatakotoranga i te tuku atu ki tētahi whakatakotoranga kino.
