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 pumau. 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 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 (taiepa 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 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.
