Paerewa Ahu:ASTM A6 / A6M.
Ngā Roa e Wātea ana:20 putu (6.1m), 40 putu (12.2m), he roa rānei kua whakaritea hei whakapai ake i te utaina o ngā ipu.
Te Maimoatanga Mata:Pango (Tae-ake), Pania ki te Parai, Pania ki te Tuku Wera rānei (ASTM A123).
Tiwhikete:Kua whakaratohia te Tiwhikete Whakamātautau Mira Katoa (MTC) e ai ki te EN 10204 3.1.
Ngā Tohungatanga ā-Rohe:E arotahi ana ki te mākete o Amerika, me ōna peka motuhake i te Hononga o Amerika me Guatemala.
Kaha Tino Pai:Ko te kaha whakaputa iti rawa o ngā kōtaha A36 he 36,000 psi (250 MPa), e whakarato ana i te pai o te hanganga nui atu i ngā kōtaha A36 paerewa.
Te Whakahaere Whai Hua:Tukunga tika mai i te tatau ki te tatau me te takai moana kua oti te whakarite kia kore ai e makuku me te waikura i te wā e kawe ana.
Ngā Kurupae me ngā PouKo ngā huānga hanga rakau me te poti noa ka pāngia e ētahi kawenga māmā ki te taumaha.
Ngā Anga Tautoko: Ngā anga e pupuri ana i ngā taputapu, ngā paipa, ngā rauemi, me ētahi atu.
Ngā Rerewē KāraniHe reri hei whakamahi me ngā kerēne haereere o ngā mahi māmā ki te mahi waenga.
Ngā Tautoko Piriti: Ngā pae here, ngā tautoko rānei mō ngā piriti he iti ngā whāwhātanga.
1. Tākai Ngaio
Takai Haumaru: Whitiki rino kaha me te parepare taha hei tiaki i te hurihanga o te flange.
Ārai i te Waikura: Kua takaihia te hua kua oti ki roto i ngā putea kirihou/whatu ā-wai me ngā putea whakamaroke ā-roto hei mimiti i te makuku.
Te whai i te katoa: kua tohua ia paihere ki te tohu whakarewa ātete-huarere Tau Wera, Tau (Gr.50) me te Rahi.

Q1: He aha te maitai ASTM A36?
A: He maitai ngawari hanganga waro-iti o Amerika Te Raki e whakamahia whānuitia ana, he tino ngāwari ki te whakarewa, ki te hanga me te pakari, he maitai whānui mō ngā mahi hanga me ngā mahi ahumahi.
P2: Te rerekētanga i waenga i te hongere-C me te hongere-MC?
A: He whāiti ngā āputa o roto o ngā hongere-C paerewa me ngā inenga paerewa Amerikana pumau. Ko ngā hongere MC (rerekē) he whānui āputa kua whakaritea me te matotoru o te whatu tukutuku mō ngā anga motuhake me ngā tono taura arawhata. E rua ngā mea e wātea ana i te taumata ASTM A36.
Q3: Ngā rahinga paerewa o ngā hongere A36?
A: E whakahaeretia ana e te paerewa ASTM A6, ko te hohonutanga kei waenga i te 3-inihi (C3) me te 15-inihi (C15). Ngā ture tohu rahi: te hohonutanga + te taumaha mō ia putu (hei tauira, C3×4.1, C8×11.5).
P4: Ka taea te whakarewa i te maitai ASTM A36?
Āe. He tino pai te āhua o te whakarewa. E tika ana ngā tikanga whakarewa noa (SMAW, GMAW, whakarewa oxyacetylene), kāore he whakamahana-mua, whakamahana-muri rānei e hiahiatia ana mō ngā matotoru paerewa.
Q5: Ka taea te whakakikorua i ngā hongere-U A36?
Āe. Nā te mea he ngāwari te waikura o te maitai waro, ko te whakapūmau wera (ASTM A123) te maimoatanga mata matua mō te ātete ki te waikura i ngā taiao o waho me te moana.
Q6: Me pēhea te pānui i te MTC maitai A36?
A: E toru ngā manatoko matua e hipokina ana e te Paerewa EN 10204 3.1 MTC: 1. Te hanganga matū (C, Mn, P, S, Si); 2. Ngā āhuatanga miihini: te kaha hua ≥36 ksi, te kaha kume 58–80 ksi, te roa ≥20%; 3. Te whai i te hua mā te tau wera ōrite.
Q7: Ngā roa paerewa kaweake?
A: Haunga te roa o te paerewa o Amerika, 20 putu/40 putu, ko ngā rahi kaweake matua ko te 5.8m/11.8m mō te uta ipu paerewa. Kei te wātea hoki te ratonga tapahi ritenga.
P8: Ngā whakamahinga noa o ngā hongere A36?
A: E whakamahia whānuitia ana i roto i ngā anga hanga, ngā tuanui, ngā wāhanga piriti, ngā arai huarahi, ngā wakatō taraka, ngā turanga miihini, ngā taputapu ahuwhenua me ngā pūnaha whakairinga pūngao rā.
