Ngā Pūrongo - ASTM A992 vs A572 vs A283 vs A913: Ngā Rerekētanga Matua o ngā Wāhanga Rino Hanganga

I ēnei rā, he mea nui te whiriwhiri i te kounga tika o te maitai mō te hanganga pai, te hanga, me te utu whānui o te kaupapa i roto i te umanga hanga. E ai ki ngā paerewa o Amerika, e whā ngā momo noa omaitai hanganga ASTM A992, A572, A283 me te A913He rerekē ngā taumata mahi me ngā whakaritenga kaupapa o ia maitai.

te rōpū hanga hanganga maitai o te kingi (2)

Ngā Rerekētanga Rauemi me ngā Rerekētanga Mīhini

ASTM A992
Kāwai: Rino hanganga kaha-teitei, iti-koranu (HSLA)
Te ahotea iti rawa: 345 MPa (50 ksi) te kaha hua
Āhuatanga: He tino whakahaeretia te hanganga o ngā "kaihanga whakarewa me ngā mea whakapau whakarewa e pā ana ki te ahotea" kia pai ai te hanga me te pakari.
Āhua Matua: I hangaia mō te flange whānui o te rōra wera (kurupae W/H).
Ko te A992 te maitai kaha-teitei paerewa i Amerika Te Raki mō te hanganga anga whare.

Ngā Māka: 42, 50, 55, 60, 65
Taumata kaha: Nui atu i te maitai waro noa.
Tukunga: Pereti, koki, awaawa, kurupae me ētahi atu
Ka taea te whakarewa i ngā kōeke iti (Kōeke 42, 50) mā te whakamahi i ngā tikanga whakarewa noa, engari me whakamahi i ngā tikanga whakarewa motuhake, i ngā whakamātautau tāpiri rānei pērā i te PWHT mō ngā kōeke o runga (Kōeke 65).

ASTM A283
Momo: maitai hanganga waro (maitai ngawari)
Ngā Māka: ABCD = E wātea ana
Kaha: He ngoikore ake i te A572 me te A992
Ka taea te kī he rite ki te hanga me te whakarewa i tētahi arewhana pēpi mō te utu o tētahi arewhana pakeke.
Ko te ASTM A283 whānui anake te mea e whakamahia ana me ngā hanganga kore-tino nui.

ASTM A913
Momo: Rino iti-koranu kaha-teitei mā te tikanga QST (whakamātao me te whakamahana-ake)
Ngā Māka: 50, 65, 70 = Kei te wātea
Āhuatanga: He kaha nui, he pakari tino pai, he pai hoki te whakarewa i roto i te maitai tino kaha.
Puka Matua mō ngā kurupae whānui matotoru me te taumaha
Ko te A913 te mea e whakamahia nuitia ana i ngā wāhi e tika ana mō te kaha teitei me ngā wāhanga hiroki i roto i ngā hanganga maitai nunui, teitei hoki.

Ngā Rerekētanga Taupānga

ASTM A992
Ngā whare rino arumoni me ngā whare
Ngā anga mō ngā whare teitei me ngā whare waenga
Ngā whare ahumahi me ngā whare tohatoha
Take: Ka taea te whakawhirinaki atu ki tēnei mea me te ngāwari ki te whakarewa, ā, ka taea hoki te whakamahi ki te tinana o te motuka.

ASTM A572
Ngā Piriti
Ngā wheketere
Ngā pourewa me ngā whakaurunga pūngao
Ngā papa taumaha
Take: Ka taea e ngā kaihoahoa te arotau i te taurite i waenga i te kaha me te utu mā te whakamahi i ngā momo maha.

ASTM A283
Ngā whare iti-teitei
Ngā whare rino māmā me ngā awheawhe
Ngā pāmu me ngā hanganga rangitahi
Ngā wāhanga kore-tino nui
Take: He iti te utu, he ngāwari hoki te kawe rauemi, engari he iti te kaha ki te kawe.

ASTM A913
Ngā whare teitei
Ngā piriti roa
Ngā papa tākaro me ngā whare hokohoko
Ngā kaupapa ahumahi taumaha
Take: Ka taea te whakatutuki i ngā mema angiangi ake me ngā whānui roa ake mā te kaha nui rawa.

Te Manakohanga Mākete me te Rohe

Hanganga Rino ASTM A992E wātea ana i te Hononga o Amerika me Kānata, te Waenganui Rawhiti, te Tonga-mā-rāwhiti o Āhia mō te Anga Hanga.

Hanganga Rino ASTM A572He mea pai ake i ngā rohe o Amerika me ngā rohe e aro nui ana ki ngā hanganga pēnei i ngā piriti me ngā hanganga taumaha.

Hanganga Rino ASTM A283E whakamahia whānuitia ana i ngā whenua o te ao tuatoru mō ngā hanganga ohanga me ngā hanganga māmā.

Hanganga Rino ASTM A913Ko te nuinga o te wā e whakamahia ana i ngā whenua whakawhanake me ngā kaupapa nui pēnei i te USA, Europe, Middle East, East Asia.

Ngā Whakaaro Utu me te Ōhanga

A283He iti te utu, he iti hoki te kounga

A992He utu taurite, he pai te taurite o te kaha me te ngāwari o te hanga

A572: Kei te kounga te utu

A913Ko te utu teitei rawa mō ia waeine, engari ko te kaha teitei ka whakaiti i te taumaha katoa o te maitai

Ka taea e ngā maitai kaha-teitei te whakaiti i ngā utu katoa o te kaupapa mā te whakaiti i ngā rahinga rauemi, te kawe me te tāutanga.

Te Hanga me te Whakarewa

A283He ngāwari ki te tapahi me te whakarewa

A992: I hangaia kia whakarewahia mō ngā hanganga

A572Ka taea te whakarewa, engari me kaha ake te whakahaere mō ngā taumata teitei ake

A913He tikanga auaha e āhei ai te kaha whakarewa pai i ngā taumata kaha tino teitei.

Whakarāpopototanga me te Whakataurite

Paerewa	Taumata Kaha	Te Whakamahinga Noa	Taumata Utu	Ngā Mākete Wera
ASTM A992	Teitei	Ngā whare, ngā anga	Waenga	USA, Waenganui Rawhiti, Āhia ki te Tonga-mā-rāwhiti
ASTM A572	Waenga-Teitei	Ngā piriti, ngā tipu	Waenga-Teitei	Amerika, Ngā rohe hanganga
ASTM A283	Iti	Ngā hanganga mārama	Iti	Āwherika, Āhia ki te Tonga, Amerika Waenganui
ASTM A913	Tino Teitei	Ngā whare teitei, ngā kaupapa nunui	Teitei	USA, Ūropi, Waenganui Rawhiti, Āhia ki te Rawhiti

E whā ngā taumata mahi a te ASTM A283, A992, A572 me te A913 mō te maitai hanganga. Ko te A283 te mea e tika ana mō te ōhanga, ko te A992 te anga hanga whare, he maha ngā kōwhiringa kaha e tukuna ana e te A572 mō ngā hanganga, ā, ko te A913 te uara pai rawa atu mō ngā tono hanganga taumaha me te kounga teitei. Nā te kaha haere o ngā kaupapa hangahanga, kei te neke haere te nuinga ki ngā maitai hanganga kaha ake i te mākete o te ao.
