I whakatūria a Royal Group i te tau 2012, he umanga hangarau matatau e arotahi ana ki te whakawhanake, te whakaputa me te hoko i ngā hua hoahoanga. Kei Tianjin tō mātou tari matua, te tāone matua o te motu, te wāhi i whānau ai a "Three Meetings Haikou". He peka anō hoki ō mātou i ngā tāone nui puta noa i te motu.
He mea hanga noa te paipa maitai waro i te waro me te rino, ā, he mea whakamahi whānuitia i roto i ngā umanga. Nā tōna pumau, tōna kaha, me tōna ātete ki te waikura, he mea whakamahi pinepine i roto i ngā umanga hinu, matū, me te hanga.
I runga i te tukanga whakaputa, ko te paipa maitai waro te nuinga o te wā ka whakarōpūtia hei paipa whakarewa me te paipa tuimotu. Ka hangaia te paipa whakarewa mā te whakarewa i ngā pereti maitai, i ngā rīpene rānei, kia pai ai te whakaputa me te iti o te utu. He mea noa te whakamahi mō te kawe wai pēhanga iti, pērā i te tuku wai whare me ngā paipa waikeri. Ka hangaia te paipa tuimotu mai i ngā pire totoka mā roto i ngā tukanga pērā i te wero, te huri wera, me te huri matao. Kāore he whakarewa i tōna pakitara, ka hua ake he kaha me te hiri, ka taea ai te tu atu i ngā pēhanga teitei me ngā taiao uaua. Hei tauira, ko ngā paipa pēhanga teitei i roto i te umanga hinu matū, he mea noa te whakamahi mō ngā paipa tuimotu.
Mā te āhua, he porowhita, he tapawhā hoki ngā āhua o ngā paipa maitai waro. He ōrite te taumahatanga o ngā paipa porowhita, ā, he iti noa te ātete ki te kawe wai. He whānuitia te whakamahinga o ngā paipa tapawhā me ngā paipa tapawhā i roto i ngā hanganga hanga me te hanga mīhini, hei tautoko i ngā hanganga. He mea nui te mahi a ngā momo paipa maitai waro rerekē i roto i ngā kaupapa hangarau rerekē.
Ā MĀTOU PAIPA RINO WARO
He whānuitanga katoa ā mātou hua maitai waro, mai i ngā paipa ki ngā pereti, ngā koiri ki ngā kōtaha, hei whakatutuki i ngā hiahia o āu kaupapa kanorau.
He mea hanga ngā paipa rino piauau mai i tētahi paipa rino whakarewa me te paninga konutea i hangaia ki te mata mā te whakapūmau wera, te whakakikorua hiko rānei. Mā te whakakotahi i te kaha teitei o te rino me te ātete pai ki te waikura o te paninga konutea, ka whakamahia whānuitia i roto i te hanganga, te pūngao, te kawe waka, me te hanga mīhini. Ko tō rātou painga matua ko te mea ka wehea e te paninga konutea te rauemi turanga mai i ngā mea waikura mā te tiaki hiko, ka roa ake te ora o te paipa me te tiaki i ngā āhuatanga miihini o te rino kia tutuki ai ngā whakaritenga kawenga hanganga o ngā āhuatanga rerekē.
Paipa Rino Porowhita Pirau
Ngā Āhuatanga Whakawhiti-WāhangaHe iti te ātete wai o te porowhita whakawhiti, he ōrite hoki te ātete pēhanga, he pai mō te kawe wai me te tautoko hanganga.
Ngā Rauemi Noa:
Rauemi TūāpapaKo te maitai waro (pērā i te Q235 me te Q235B, he kaha āhua, he utu iti hoki), ko te maitai iti-koranu (pērā i te Q345B, he kaha teitei, he pai mō ngā mahi taumaha); ko ngā rauemi turanga kowiri tira (pērā i te maitai kowiri tira 304 kua whakapūmautia, e ātete ana ki te waikawa me te kawakore me te ātaahua) e wātea ana mō ngā mahi motuhake.
Ngā Rauemi Paparanga PirauKonutea parakore (te whakakākano wera me te ihirangi konutea o ≥98%, te matotoru o te paparanga konutea o 55-85μm, me te wā tiaki waikura o 15-30 tau), te konutea koranu (konutea whakakikoruatia hiko me te iti o te konumohe/nikara, te matotoru o 5-15μm, e tika ana mō te tiaki waikura o roto).
Ngā Rahi Noa:
Diameter o WahoDN15 (1/2 inihi, 18mm) ki te DN1200 (48 inihi, 1220mm), Matotoru o te Pakitara: 0.8mm (paipa whakapaipai pakitara-angiangi) ki te 12mm (paipa hanganga pakitara-matotoru).
Ngā Paerewa e tika ana: GB/T 3091 (mō te kawe wai me te hau), GB/T 13793 (paipa maitai hiko-whakarewa hononga tika), ASTM A53 (mō ngā paipa pēhanga).
Ngongo Tapawhā Rino Pirau
Ngā Āhuatanga Whakawhiti-WāhangaHe tapawhā te tapawhā (te roa o te taha a×a), he pakari te takahuri, he ngāwari te hononga papatahi, e whakamahia whānuitia ana i roto i ngā hanganga anga.
Ngā Rauemi Noa:
Ko te turanga matua ko te Q235B (e tutuki ana i ngā whakaritenga amo kawenga o te nuinga o ngā whare), me te Q345B me te Q355B (he kaha ake te whakaputa, e tika ana mō ngā hanganga ātete rū whenua) e wātea ana mō ngā tono teitei.
Ko te tukanga whakapūmau he whakapūmau wera-tuku (mō te whakamahinga o waho), ko te whakapūmau hiko he mea whakamahi pinepine mō ngā ārai whakapaipai o roto.
Ngā Rahi Noa:
Roa o te taha: 20×20mm (ngā whata iti) ki te 600×600mm (ngā hanganga maitai taumaha), matotoru o te pakitara: 1.5mm (ngā ngongo tāonga pakitara angiangi) ki te 20mm (ngā ngongo tautoko piriti).
Roa6 mita, e wātea ana ngā roa ritenga o te 4-12 mita. Me whakarite wawe mō ngā kaupapa motuhake.
Ngongo Tapawhā Rino Pirau
Ngā Āhuatanga Whakawhiti-Wāhanga: Tapawhā rite (te roa o te taha a×b, a≠b), ko te taha roa e whakanui ana i te ātete piko, ko te taha poto e tiaki ana i te rauemi. He pai mō ngā whakatakotoranga ngāwari.
Ngā Rauemi Noa:
He rite tonu te rauemi turanga ki te ngongo tapawhā, ā, neke atu i te 70% te nui o te Q235B. Ka whakamahia ngā rauemi iti-koranu mō ngā āhuatanga kawenga motuhake.
Ka whakarerekētia te matotoru o te whakapūmau i runga i te taiao mahi. Hei tauira, ko te whakapūmau i te whakapūmau wera i ngā rohe takutai e hiahiatia ana he ≥85μm.
Ngā Rahi Noa:
Roa o te taha: 20×40mm (taupoki taputapu iti) ki te 400×800mm (ngā purlin o te tipu ahumahi). Matotoru o te pakitara: 2mm (kawenga māmā) ki te 25mm (pakitara matotoru rawa, pērā i ngā mīhini tauranga).
Manawanui Ahu:Hapa Roa Taha: ±0.5mm (ngongo tino tika) ki te ±1.5mm (ngongo paerewa). Hapa Matotoru Pakitara: I roto i te ±5%.
He whānuitanga katoa ā mātou hua maitai waro, mai i ngā paipa ki ngā pereti, ngā koiri ki ngā kōtaha, hei whakatutuki i ngā hiahia o āu kaupapa kanorau.
He paipa whakarewa te paipa kowiri tira e whakakotahi ana i te ātete ki te waikura, te kaha teitei, te akuaku me te tiaki taiao. Ka kapi i ngā momo paipa rerekē pērā i ngā paipa tuitui me ngā paipa whakarewa. He whānuitia te whakamahinga i roto i te hangarau hanga, te matū me te rongoā, te kawe pūngao me ētahi atu mara.
Mai i te tirohanga whakaputa, ko ngā ngongo porowhita kowiri tira ka whakarōpūtia ki roto i ngā momongā ngongo tuituimengā ngongo whakarewa. Ngā ngongo tuikoreka hangaia mā roto i ngā tukanga pēnei i te poka, te hurihuri wera, me te kume makariri, ka kore ai he hononga whakarewa. Ka nui ake te kaha whānui me te ātete ki te pēhanga, ka pai ai mō ngā mahi pēnei i te kawe wai pēhanga teitei me te kawe kawenga miihini.Ngā ngongo whakarewahe mea hanga mai i ngā rau kowiri tira, ka hurihia kia āhua, kātahi ka whakarewaina. He nui te whai huatanga o te whakaputa me te iti o te utu, nā reira e whakamahia whānuitia ana mō te kawe pehanga iti me ngā mahi whakapaipai.
Ngā Ahu Whakawhiti-Wāhanga: Kei roto i ngā ngongo tapawhā te roa o te taha mai i ngā ngongo iti 10mm×10mm ki ngā ngongo nui 300mm×300mm. He maha ngā rahi o ngā ngongo tapawhā rite ki te 20mm×40mm, 30mm×50mm, me te 50mm×100mm. Ka taea te whakamahi i ngā rahi nui ake hei tautoko i ngā hanganga i roto i ngā whare nui. Te Awhe Matotoru o te Pakitara: Ko ngā ngongo angiangi (0.4mm-1.5mm te matotoru) e whakamahia ana i roto i ngā mahi whakapaipai, he mama, he ngāwari hoki te tukatuka. Ko ngā ngongo matotoru (2mm te matotoru me te neke atu, ko ētahi ngongo ahumahi e eke ana ki te 10mm me te neke atu) he pai mō ngā mahi kawe kawenga ahumahi me te kawe pēhanga teitei, e tuku ana i te kaha me te kaha kawe pēhanga nui ake.
Mō te whiriwhiri rauemi, ko ngā ngongo porowhita kowiri tira he mea hanga i te nuinga o ngā momo kowiri tira matua. Hei tauira,304e whakamahia whānuitia ana mō ngā paipa tukatuka kai, ngā reera hanga whare, me ngā taputapu o te whare.316He maha ngā whakamahinga o ngā ngongo porowhita kowiri tira i roto i ngā hanganga takutai moana, ngā paipa matū, me ngā taputapu kaipuke.
Ngā ngongo porowhita kowiri tira ōhanga, pērā i201me430, e whakamahia nuitia ana i roto i ngā ārai whakapaipai me ngā wāhanga hanganga mama, ina iti ake ngā whakaritenga ātete ki te waikura.
