Ngā Pātai Auau:
P: He aha te rerekētanga i waenga i te EN 10219 S355JRH me te EN 10210 S355JRH?
A: Ko te EN 10219 mō ngā wāhanga tuwhera kua whakarewahia i te matao (ka mahia te whakarewa me te hanga i te pāmahana rūma). Ko te EN 10210 mō ngā wāhanga tuwhera kua oti te wera (kore hononga, kua whakarewahia rānei, kātahi ka whakamahanatia). Mō ngā paipa LSAW, ko te EN 10219 te paerewa e tika ana. Ko ngā wāhanga kua oti te wera EN 10210 he hononga, he ERW rānei. He rite tonu ngā āhuatanga miihini o ngā mea e rua.
Q: Ka taea e koe te tuku i te S355J2H (pānga i te -20°C) hei utu mō te S355JRH?
Āe. Kei te wātea te S355J2H ina tonoa mō ngā tono pāmahana iti pēnei i ngā hanganga moana, ā-arctic rānei. He rite tonu te hanganga matū engari he iti ake ngā rohe me te pānga Charpy kua whakamanahia i te -20°C (iti rawa 27J). He utu tāpiri kei te hiahiatia.

Āe. Kei a Womic Steel te tiwhikete Whakahaere Whakaputa Wheketere (FPC) i raro i te EN 10219. Ka whakaratohia e mātou he tohu CE me te Whakapuakitanga Mahi (DoP) mō ngā paipa e hokona ana ki te Rohe Ōhanga o Ūropi (EEA). Mā tēnei ka maeneene te whakawāteatanga tikanga me te whakaae kaupapa.
Q: He aha te roa mōrahi mō te whakapūmau i te whakarewa wera?
A: Ko te roa o te kaukau o tā mātou hoa whakapūmau he 13.5m. Nō reira, ka taea te rumaki katoa i ngā paipa tae atu ki te 12.5m me te whakapūmau. Mō ngā paipa roa ake, ka taea e mātou te whakarite whakapūmau wāhanga, te paninga rānei i tētahi atu paninga (epoxy whai konutea). Tena koa whakapā mai ki a mātou mō ngā whakaritenga roa motuhake.
Q: Ka taea e koe te huri i te whakarewa whakarewa mō te maitai hoahoanga e kitea ana?
Āe. Mō ngā paipa hanganga e kitea ana (hei tauira, ngā pou i ngā taunga rererangi, ngā āwhata piriti), ka taea e mātou te huri i te taupoki whakarewa SAW kia ōrite ki te tinana paipa. He mahi tāpiri tēnei, ā, ka tāpirihia he utu me te wā arahi (tata ki te +15%). Ka tūtohu mātou kia tohua tēnei whakaritenga i te wā o te ota.
Q: He aha te paninga e taunakitia ana mō te maitai hanganga o waho?
A: Mō te whakaaturanga o waho, ko te paninga parai (epoxy whai konutea, 60-80 maikorona) te paerewa mō te tiaki rangitahi i te wā hanga. Mō te tiakitanga tuturu me te kore e peita, ko te whakakākahu wera (85-100 maikorona) te mea pai mō ngā taiao kaha. Mō ngā whakamahinga o roto, he rawaka te mata kua pania ki te hinu, he parai iti rānei.
P: He aha te roanga o te wā arahi mō ngā paipa hanganga S355JRH LSAW?
A: Te wā arahi paerewa: 30-45 ngā rā mō ngā rahi JCOE/UOE. Mō te pakitara taumaha pereti hurihuri (> 50mm): 45-60 ngā rā. Mō te whakaotinga whakarewa me te whakaotinga whenua: tāpirihia kia 2 wiki. Mō te whakakākahu wera-tuku: tāpirihia kia 1-2 wiki i runga i te wātaka kaukau.

Ngā Wero Hangarau me ngā Otinga:
● Te whakaritenga huri whakarewa maitai kua whakakikoruatia e te hoahoa whare– E kitea ana te hanganga o te tuanui o te papa tākaro mai i roto, i waho hoki. I hiahiatia e te kiritaki kia hurihia ngā taupoki whakarewa kia rite ki te tinana o te paipa kia maeneene te āhua. I mahi a Womic i te huri whakarewa mā te whakamahi i ngā mīhini huri porowhita aunoa, ā, i muri mai ka oti te whakaoti ā-ringa. I tirotirohia ia whakarewa mō te maeneene (te taratara o te mata Ra ≤ 6.3μm). I tāpirihia tēnei e 2 wiki ki te hanga engari i tutuki te whakaotinga ataahua e hiahiatia ana.
● Te whakaritenga tika teitei– I hiahiatia ngā paipa he tika ≤ 0.15% mō te mowhiti pēhitanga (e whakaaetia ana te 0.2%). I whakamahia e Womic ngā tukanga UOE me JCOE me te whakawhānui ā-mīhini hei whakatutuki i te tika o te 0.08-0.12%. I inehia ia paipa ki runga i tētahi ripanga tika (whakatikatika laser). I whakatikatikahia ngā paipa i waho o te manawanui mā te whakamahi i tētahi perehi waipēhi.
● Paninga paninga mō te taiao koraha– He teitei te pāmahana o Qatar (tae atu ki te 50°C), he nui te haumākū (tae atu ki te 85% i te takurua), ā, he onepū hoki kei te rangi. I pania he paninga epoxy whai konutea (60 microns) ki ngā paipa katoa. I paahitia te paninga i te whakamātautau rehu tote (1,000 hāora, ASTM B117) me te iti iho i te 2mm te ngoki. Te kitenga hararei i te 2kV. I inehia te piri i te 8 MPa (iti rawa 5 MPa).
● Ngā mahi whakahaere uaua i te wā o te matapihi hanga FIFA– He iti te kaupapa mahi mō te hanganga o te papa tākaro (2020-2021). E whā ngā tuku paipa i tukuna e Womic (800-1,000 tana ia) mō ngā marama e waru. I tukuna ngā paipa mai i Shanghai ki Hamad Port (Doha), kātahi ka haria ki te taraka mō te 45km ki te wāhi i tū ai te papa tākaro. Nā ngā here COVID-19, kāore i taea e ngā kaitirotiro o Womic te haere. I whakaritea e mātou he tirotiro tirotiro mamao mā te whāngai ataata ora (TÜV ipurangi). I tangohia katoatia ngā 3,480 tana mai i tawhiti.
● Te pakari o te pānga mō te pāmahana iti pea o te taiao– Ahakoa he wera a Qatar, ka taea e te pō te heke ki te 10°C i te takurua, ā, ka kitea te hanganga o te tuanui. E hiahiatia ana te pānga Charpy i te 0°C (27J min) mō te EN 10219 S355JRH. I tutuki i a Womic te 80-120J, he nui ake i te whakaritenga. I whakaurua ngā pūrongo whakamātautau ki te mōkihi CE DoP.
●Hua:I whakatuwheratia te Papa Tākaro o Al Wakrah i te tau 2022, ā, e ono ngā whakataetae Ipu o te Ao i tū ai. Kua whakanuia whānuitia te hanganga o te tuanui rino mō tōna hoahoa huatau. I kōrero te kaiwhakatū (he kaihanga rino matua o Ūropi) kāore he hapa whakarewa i te wā i whakatūria ai. I tino pai te uru o ngā paipa LSAW katoa ki te papaanga, kāore he mahi anō. I whiwhi a Womic Steel i tētahi reta mihi mai i te kaiwhakatū matua mō te "tino tika o te āhua me te whakaoti whakarewa." Kei te mahi tonu te papa tākaro hei wāhi hākinakina me ngā huihuinga maha-whakamahinga.
