I te mea ka piki haere te tono mō ngā rauemi paipa i roto i te ao ahumahi, ka piki haere tonu te rongonui o ngā paipa tuitui me ngā paipa whakarewa. Ka tātarihia whānuitia e tēnei tuhinga mai i ngā tirohanga o te hanganga rauemi, ngā painga matua, ngā tikanga wehewehe me ngā mara e tika ana, ā, ka whakakotahi i ngā kupu matua rapu rongonui "te kōwhiringa rauemi paipa pēhanga teitei" me "ngā rauemi hanga iti te utu" hei whakarato tohutoro mō te hoko hangarau.
1. Te hanganga o ngā rauemi
Paipa tuitui
Ngā rauemi matua: te maitai waro kounga teitei (pēnei i te maitai 20, te maitai 35), te maitai koranu (pēnei i te 16Mn, 40Cr), te maitai kore waikura (304/316L) me te maitai kōhua (20g)
Ngā Āhuatanga: kāore he whakarewa, he ōrite te hanganga, he pai mō ngā āhuatanga pāmahana tiketike me te pēhanga tiketike.
Paipa whakarewa
Rauemi matua: maitai waro iti (Q235), maitai koranu iti (L290, L360), maitai piauau me te maitai kore waikura
Ngā Āhuatanga: i hangaia mā te whakarewa i ngā pereti maitai, he iti te utu me ngā whakatakotoranga ngāwari.
2. Te whakataurite i ngā painga matua
Kāwai Ngā painga o ngā paipa tui kore Ngā painga o ngā paipa whakarewa
Kaha He kaha whānui teitei, ātete pēhanga neke atu i te 415MPa16 He iti ake te kaha whakarewa, engari ka taea te whakatutuki i ngā whakaritenga pēhanga iti.
Tukanga Kāore he whakarewa, karohia te mōrearea turuturu15 He pai te whakaputa, he iti iho te utu 30%-50%
Āhua He mata maeneene, kāore he tohu tukatuka3 Kei reira ngā whakapiringa, me rongoa te mata hei whakapai ake i te āhua6
Te tono Hinu me te hau pēhanga teitei, te mana karihi, ngā mīhini tino tika5 Ngā hanganga hanga, te hangarau ā-tāone, te whakamakuku ahuwhenua
3. 4 ngā taahiraa hei wehewehe i ngā paipa tuitui mai i ngā paipa whakarewa
Mātakihia te whakarewa: ka kitea ngā tohu whakarewa raina i ngā pakitara o roto, o waho hoki o te paipa whakarewa, ā, kāore he hononga o te paipa tuitui.
Kaha whakamātautau: ka taea e ngā paipa tui kore te tu atu ki ngā whakamātautau pēhanga wai teitei ake (pērā i runga ake i te 30MPa)
Tātarihia te wāhanga whakawhiti: he ōrite te wāhanga whakawhiti o te paipa tui, ā, tera pea he rerekētanga matotoru iti o te paipa whakarewa nā te whakarewatanga
Tirohia te tiwhikete: me whakarato ngā paipa tuimotu i ngā pūrongo kitenga hapa rauemi, ā, ko ngā paipa whakarewa e arotahi ana ki te tiwhikete kounga whakarewa
4. Ngā horopaki tono kua tūtohutia
Ngā paipa tuitui:
Hinu me te hau māori: ngā paipa tuku pēhanga teitei (te kounga maitai X60/X70)
Pūngao me te mana: ngā paipa pūwero, ngā pūnaha whakamatao mana karihi
Te hangahanga teitei: ngā paipa waipēhi rererangi, ngā toki taraiwa motuka
Paipa whakarewa:
Te hangarau hanga: anga hanganga maitai, tūāpapa
Te oranga ā-tāone: te whatunga tuku wai me te rerenga wai, te pūnaha HVAC
Ahuwhenua me te ahumahi: ngā paipa whakamakuku, ngā whata rokiroki
V. Jindalai Steel: He otinga paipa kotahi-mutu
Hei whakautu i ngā rapunga wera o ngā rā tata nei mō te "tuku i te wāhi" me ngā "paipa utu-whai hua", kua riro ko te Kamupene Rino Jindalai te whiringa tuatahi a te umanga me ēnei painga e whai ake nei:
Ngā kāwai katoa: te kapi i te maitai waro, te maitai koranu, ngā paipa kore-kowiri tira me ngā paipa whakarewa, e tautoko ana i ngā rahi kore-paerewa kua whakaritea
Painga utu: ka whakaitihia ngā utu e te whakaputanga nui, ā, ko te utu mō ia paipa whakarewa he 10% te iti iho i te mākete
Te whakapūmautanga kounga: whakarato i ngā pūrongo tirotiro tuatoru (pēnei i te SGS, BV), kia rite ki te GB/T 3091, GB/T 9711 me ētahi atu paerewa ā-motu
Whakautu tere: 5,000 tana o ngā taonga e tū ana
Whakamutunga
Ahakoa he paipa kore hononga i raro i ngā āhuatanga pēhanga teitei, he paipa whakarewa whai hua, whai hua rānei, mā te whiriwhiri i ngā rauemi tika ka taea te whakanui ake i ngā painga o te kaupapa. Ko Jindalai Steel, me te hangarau hei tautoko me te ratonga hei matua, e whakarato ana i ngā otinga paipa utu-pai ki ngā kiritaki o te ao hei āwhina i ngā kaupapa kia tau pai!
(Mēnā kei te hiahia koe i ngā tawhā rauemi motuhake, i ngā utu rānei, whakapā atu ki te Rōpū Kaitohutohu Rino Jindalai kia whiwhi ai i tētahi otinga motuhake!)
