Ngā Pūrongo - Ngā Tohu Kurupae H Hanganga Rino: Whakataurite Paerewa ASTM, EN me GB

I roto i te umanga hanga whare me ngā hanganga o te ao, he mea nui kia whiriwhiria ngā rauemi hanganga tika mō te haumaru, te roa o te ora me te whai hua o te utu. Nā te mea he ingoa rongonuiKaiwhakarato H-Rama,Kia mōhio ki ngā paerewa maitai o te ao katoa - Ngā Paerewa o te Ao mō te maitai - ASTM (Amerika), EN (Pākehā), GB (Hainamana) - Me mārama ngā kaihangarau me ngā kaihoko.

Kei roto i tēnei aratohu he whakamārama whānui mō ngā momo maitai e whakamahia whānuitia ana eKurupae H Waro RinoNgā kaihanga puta noa i te ao.

Ngā Paerewa ASTM (Amerika ki te Raki)

Ko te American Society for Testing and Materials (ASTM) te paearu mō te nuinga o ngā kaupapa i te Ao Hauāuru.

Kurupae H ASTM A36Ko te momo "maitai ngawari" e whakamahia whānuitia ana. Mēnā he 36 ksi (250 MPa) te iti rawa, he teitei te kaha whakaputa, ā, he pai te kaha whakarewa me te ngāwari o te whakarewa, ā, koinei tētahi o ngā maitai pai rawa atu mō te hanganga whānui me ngā huihuinga pūtu.

A572 H Kurupae (Taumata 50)He maitai koranu iti kaha teitei (HSLA). Nā te kaha whakaputa teitei ake (50 ksi / 345 MPa) o te kurupae H A572 ki te whakataurite ki te A36, ka taea te whakamahi i ngā wāhanga mama ake mō te kawenga kotahi, ā, ka penapena i te taumaha o te kaupapa whānui.

A992 H KurupaeKo te huarahi kē atu e whakamahia whānuitia ana mō ngā kurupae whānui-flange i te US ka kitea e koe i ēnei rā. He matū ahurei, i hangaia mō te whakarei ake i te kaha whakarewa me te ōwehenga hua-ki-te-kukui whaiti ake mō ngā tono ru whenua.

Ngā Paerewa EN (Ūropi)

Te Paerewa Pākehā (EN 10025 H Kurupae) e whakamahi ana i tētahi tikanga whakaingoa i runga i te kaha hua iti rawa i roto i ngā Megapascals (MPa).

S235JR H KurupaeKo te kounga Pākehā o te A36. Ko tōna kaha whakaputa he 235 MPa. Ko te tohu "JR" i ahu mai i te mea kua whakamatautauria te maitai ki te pānga i te pāmahana rūma (20°C).

S275JR H KurupaeHe maitai hanganga waenga (kaha hua = 275 MPa). He mea whakamahi noa i roto i te hanga piriti me ngā anga taputapu taumaha.

S355JR H KurupaeKo te Kurupae Rino Kaha Teitei S355JR te momo kurupae kaha teitei e whakamahia whānuitia ana i roto i te rārangi EN. Me te kaha whakaputa o te 355 MPa, koinei hoki te rauemi whiriwhiri mō ngā whare teitei me ngā hanganga tai moana, he mea nui te ōwehenga taumaha ki te kaha.

Ngā Paerewa o te UK (Haina)

I te mea ko Haina tonu te kaihanga nui rawa atu o te ao, he maha ngāmaitai waroNgā Kaiwhakarato H-Rārangiwhai i te paerewa GB/T 11263.

Kurupae H Q235He rite ki te S235JR me te A36. Ko te tohu "Q" i te Q235 e tohu ana i te pūwāhi hua, ko te 235 e tohu ana i te kaha i roto i te MPa. He mea whakamahi noa hoki i roto i ngā whare tuarua me ngā pourewa waea.

Q355 H KurupaeKo te whakakapi i te momo Q345 tawhito, koinei te mea tino kaha mō ngā hanganga Hainamana. E mōhiotia ana ko te S355JR ōrite, e whakamahia whānuitia ana i roto i ngā whare maitai kua oti te hanga (PEB) me ngā whare ahumahi nunui.

He aha te mea nui ki te whiriwhiri i te kaiwhakarato rama H tika

Hei whakatere i ēnei paerewa, me whai hoa mahi koe me te tohungatanga ki te tiwhikete whakawhiti-rohe.Ngā Kaihanga H-Rārangikei te tuku inaianei i ngā Tiwhikete Whakamātautau Mira (MTC) e tohu ana i te "Tiwhikete Takirua;" ka taea te tiwhikete i tētahi kurupae mō te S355JR me te Q355 i te wā kotahi.

Ahakoa kei Mexico tō whare putunga, kei Philippines rānei tō piriti, mā te whiriwhiri i te momo tika mō te mahi ka marino te ngākau i te mōhio ka pakari te hanganga o te mahi, ā, ka whakamahia pai hoki e koe tō tahua rauemi.
