1. Te Whānuitanga me te Whakarōpūtanga

Tukanga Hanga: E pā ana ki ngā paipa maitai kua whakarewaina pērā i te whakarewa ātete hiko (ERW) me te whakarewa pewa ruku (SAW).

Whakarōpūtanga: Kua whakarōpūtia ki te Akomanga A (taumata taketake) me te Akomanga B (taumata matatau) i runga i te kaha o te tirotiro. Ko te P355NH ka tukuna i te nuinga o te wā hei Akomanga B.

2. Ngā Tikanga Tukunga Whānui

Kounga Mata: Kāore he hapa pēnei i te ngatata me te piko. Ka whakaaetia te iti o te unahi waikura (kāore e pā ki te tirotiro).

Tohu: Me tohu ia paipa maitai ki te tau paerewa, te taumata maitai (P355NH), te rahi, te tau oumu, me ētahi atu (EN 10217-1).

Ngā taipitopito tukanga matua o te paipa maitai P355NH

1. Te whakahaere i te tukanga welding (EN 10217-3)

Paipa maitai ERW:

Me whai maimoatanga wera ipurangi i muri i te whakarewa auau-tiketike (whakamahana whakapūmau ki te 550 ~ 600℃me te whakamatao puhoi).

Te whakahaere i te tuitui whakarewa:≤10% te matotoru o te pakitara (kia kore ai e hanumi kāore i oti). 

Paipa maitai SAW: 

Whakarewa maha-waea (2~4 waea), whakauru wera≤35 kJ/cm (hei ārai i te whakakorikori o te kakano HAZ). 

1. Ngā whakaritenga mō te whakamahana (EN 10217-3 + EN 10028-3)

Tukanga	ngā tawhā	Kaupapa
Te Whakaōrite (N)	910±10℃×1.5min/mm, whakamatao hau	Whakamahingahia ngā kakano ki te taumata ASTM 6~8
Te whakamahana i te ahotea (SR)	580~620℃×2min/mm, whakamatao oumu (≤200℃/h)	Whakakorehia te ahotea toenga whakarewa

3. Nga whakamatautau kore kino (EN 10217-1 + EN 10217-3)

Whakamātautau UT:

Te aro nui:ΦKōhao papatahi 3.2mm (EN ISO 10893-3). 

Taupoki: 100% whakarewa + rauemi matua 10mm i ngā taha e rua. 

Whakamātautau pēhanga wai: 

Pēhanga whakamātautau = 2×te pēhanga mahi e whakaaetia ana (iti rawa 20MPa, te pupuri pēhanga≥15 hēkona).

Ngā whakaritenga tāpiri mō ngā tono motuhake

1. Te pakari o te pānga pāmahana iti (-50℃)

Ngā tikanga whakaaetanga tāpiri:

Pūngao pānga≥60J (toharite), tauira kotahi≥45J (EN ISO 148-1). 

Whakamahia te tukanga tango-hauora whakahiato Al+Ti hei whakaiti i te nui o te hāora (≤(30ppm). 

2. Kaha ātete pāmahana teitei (300℃)

Whakamātautau tāpiri:

Te kaha pakaru ngoki 10^5 hāora≥150 MPa (ISO 204).

Raraunga kume pāmahana teitei (Rp0.2@300℃≥300 MPa) e hiahiatia ana.

3. Ngā whakaritenga ātete ki te waikura

Tukanga kōwhiringa:

Ko te pupuhi o te pakitara o roto (Sa 2.5 taumata, EN ISO 8501-1).

Kua pania te pakitara o waho ki te koranu Zn-Al (150g/m²(( ...

Ngā Tuhinga Kounga me te Tiwhikete (EN 10217-1)

Tiwhikete Tirotiro:

Tiwhikete EN 10204 3.1 (tirotiro-ā-tangata a te wheketere maitai) Tiwhikete 3.2 rānei (tiwhikete tuatoru).

Me whakauru atu ki roto: te hanganga matū, ngā āhuatanga hangarau, ngā hua NDT, te pihi maimoatanga wera.

Tohu motuhake:

Ko ngā paipa pāmahana iti kua tohua ki te "LT" (-50℃). 

Ko ngā paipa pāmahana teitei kua tohua ki te "HT" (+300℃).

Ngā raruraru me ngā otinga noa

Te Āhuatanga Raru	Tātari Take	Ngā Otinga (I runga i ngā Paerewa)
Kāore i te rawaka te kaha pānga o te whakarewas	ngā witi HAZ matotoru	whakarerekētia te whakauru wera whakarewa≤25 kJ/cm (EN 1011-2)
Te turuturu whakamātautau waipēhi	Ngā tawhā mīhini whakatika hē	Arotakenga anō a UT i te wāhanga paipa katoa + tirotironga ira-X ā-rohe (EN ISO 10893-5)
