Te Mārama ki ngā Rerekētanga i waenganui i ngā Taumata AH36, DH36, me EH36

Te Kaupae Rino	Kaha Hua (MPa)	Kaha Kume (MPa)	Te Pāmahana Whakamātautau Pānga	Te Whakamahinga Noa
AH36	355	490–620	0°C	Ngā hanganga whānui o ngā takere kaipuke me ngā papa
DH36	355	490–620	-20°C	Ngā papaaho o te moana, te whakamatao i te wai moana
EH36	355	490–620	-40°C	Ngā taiao moana Arctic me ngā taiao moana cryogenic

He rite tonu ngā mea e torukaha ā-mīhini, engari ko tā rātoute kaha mimiti pūngao pānga i ngā pāmahana rerekēe tautuhi ana i tō rātou whakarōpūtanga me tō rātou whakamahinga.

Te Hanganga Matū

Tehanganga matūHe tata rite tonu ngā mea o AH36, DH36, me EH36, i hangaia kia kaha ai, kia pai ai te whakarewa, kia ātete hoki ki te waikura.

Te Hanganga Matū Noa (%):

• Waro (C):≤ 0.18

• Manganēhi (Mn):0.90–1.60

• Hiraka (Si):0.10–0.50

• Whēkau (P):≤ 0.035

• Whānariki (S):≤ 0.035

• Niobium (Nb), Vanadium (V), Titanium (Ti):≤ 0.10

Ka whakatikatikahia e ngā huānga whakakoi-iti pērā i te niobium, te vanadium, me te titanium te hanganga o te witi, ka whakarei ake i te kounga o te maitai.te pakari, te ātete ki te ngenge, me te kaha ā-mīhini.

Ngā Āhuatanga Mīhini

AH36, DH36, me EH36he maitai kaha-teitei katoa me te rite tonute kaha whakaputa iti rawa o te 355 MPamete kaha kume mai i te 490 ki te 620 MPa.

Ngā Āhuatanga Mīhini Noa:

• Te Kaha o te Hua:≥ 355 MPa

• Kaha Kume:490–620 MPa

• Te roa (i roto i te 50 mm):≥ 21%

• Te pakeketanga (HB):170–220

Ko te rerekētanga matua i waenganui i a rātou kei roto ipakari pānga, i inehia mā roto i ngā whakamātautau Charpy V-Notch (CVN) i ngā pāmahana rerekē:

• Ka whakamatautauria a AH36 i0°C.

• Ka whakamatautauria a DH36 i-20°C.

• Ka whakamatautauria a EH36 i-40°C.

Ko te iti iho o te pāmahana whakamātautau, ko te nui ake o te kaha o te maitai ki te pupuri i te pakari me te ārai i te pakarukaru i ngā taiao makariri.

Ngā Rerekētanga Matua i waenganui i te AH36, te DH36, me te EH36

1. Te Kaha Pānga

Ko te rerekētanga tino nui i waenga i ngā taumata e toru ko tō rātoute ātete ki te pakarukarui ngā pāmahana rerekē.

• AH36mahi pono i roto ingā āhuarangi ngawari, e tika ana mō ngā kaipuke e mahi ana i raro i ngā āhuatanga moana paerewa.

• DH36e whakarato ana i te pakari pai ake, e pai ai mōngā rohe makariri me ngā papaaho moana.

• EH36ka tukuna he kaha pānga tino pai kingā pāmahana i raro i te kore, pai rawa atu mōNgā kaipuke o te Ātiki, ngā kaikawe LNG, me ngā kaipuke porowhita.

Mā tēnei rerekētanga ka whakamahia ia momo ki ngā wāhi e taea ai te whakarato i te haumaru mōrahi i raro i te ahotea taiao.

2. Awhe Pāmahana Ratonga

• AH36:Hei whakamahi i roto ingā āhuarangi mahana ki te mahana(i runga ake i te 0°C).

• DH36:Mōngā āhuatanga makariri(ki raro ki te -20°C).

• EH36:Mōngā taiao tino makariri(ki raro ki te -40°C).

Ko ngā kaipuke, ko ngā hanganga tai moana rānei e mahi ana i ngā wā hukapapa, i ngā wā porowhita rānei, e whakawhirinaki ana ki te EH36 hei ārai i te ngatata o te hanganga nā te pakarukaru i puta mai i te pāmahana.

3. Taiao Taupānga

Ahakoa he maitai moana ngā momo katoa, he rerekē te whakamahinga i runga i te pānga ki te taiao:

• AH36:Ngā waka takere whānui, ngā kaipuke utanga, me ngā kaipuke kawe papatipu.

• DH36:Ngā papa keri moana, ngā kaipuke tāke e rere ana i te moana nui, me ngā kaipuke i ngā ara wai matao.

• EH36:Ngā waka pakaru hukapapa, ngā kaipuke rangahau porowhita, me ngā papaaho moana hohonu.

4. Te Whakamātautau me te Tiwhikete

Me tutuki i ia taumata ngā paerewa whakamātautau tino pakari kua tautuhia eABS (Tari Tukunga o Amerika)me ētahi atu rōpū whakarōpūtanga. Ko te rerekētanga opāmahana whakamātautau pāngakia noho haumaru ai te mahi a ia momo maitai i roto i tōna taiao e tika ana.
