AH36 vs DH36 vs EH36: Ko tēhea te momo pai rawa atu mō tāu kaupapa hanga kaipuke?

Tau	Te Kaha o te Hua	Kaha Kume	Te Pāmahana Whakamātautau Pānga	Te Whakamahinga Noa
AH36	≥ 355 MPa	490 ki te 620 MPa	0°C	Ngā āhuarangi ngawari me ngā āhuarangi taurite
DH36	≥ 355 MPa	490 ki te 620 MPa	-20°C	Ngā rohe makariri me ngā hanganga taumaha
EH36	≥ 355 MPa	490 ki te 620 MPa	-40°C	Ngā rohe Ātiki, ngā waka akomanga hukapapa

Ahakoa he rite te kaha o ngā momo e toru, ko te EH36 te mea tino pakari, ā, muri iho ko te DH36, kātahi ko te AH36.

Ngā Āhuatanga Matū Ngā Āhuatanga Rite me Ngā Rerekētanga

Ka pā te hanganga matū ki te kaha whakarewa, te ātete ki te waikura, me te pakari. Ko ngā momo e toru e whai ake nei:

• Te ihirangi waro whakahaeretia

• Manganese mō te kaha

• Hiraka mō te pumau

• Ngā huānga moroiti-koranu pērā i te Nb, Ti, V rānei hei whakamahine i te witi

Heoi, he kaha ake ngā mana whakahaere o te EH36 me te DH36, ā, ka hiahiatia pea he koranu tāpiri hei whakatutuki i ngā paerewa pānga pāmahana-iti.

He aha te Hiranga o te Pakari Pānga i roto i te Hanganga Moana

Ngā wheako o ngā kaipuke me ngā hanganga tai moana:

• Te pānga o te ngaru

• Ngā piki me ngā heke o te pāmahana

• Te whakarerekētanga o te anga

• Te wiri

• Utaina hihiri

Mā te pakari i ngā pāmahana iti ka kore te maitai e pakarukaru. Koinei tētahi o ngā take e tino whakahaere ana ngā rōpū whakarōpū i ngā whakaritenga AH36, DH36, me EH36 i ngā rohe hanganga matua.

Ngā Whakamahinga o ngā Pereti Rino AH36, DH36, me EH36

Ngā Taupānga AH36

E whakamahia whānuitia ana te AH36 i roto i:

• Ngā hanganga papa

• Ngā Hanganga Matua

• Ngā waka āhuarangi māmā ki te āhuarangi ngāwari

• Ngā wāhi pupuri utanga

• Ngā wāhanga kaipuke i runga ake i te raina wai

He tino pai te kaha me te āheinga whakarewa, ā, he pai mō te hanga kaipuke whānui.

Ngā Taupānga DH36

He pai rawa te DH36 mō:

• Ngā waka e mahi ana i ngā rohe makariri

• Ngā wāhanga hanganga e hiahia ana kia pakari teitei

• Ngā papa o runga me ngā ārai i ngā āhuarangi waenga-whānui

• Ngā kaipuke tautoko o waho

• Ngā turanga taumaha

He maha ngā wā ka tohua te DH36 i roto i ngā tuhi a te rōpū whakarōpūtanga mō ngā rohe tino nui.

Ngā Taupānga EH36

Kua whiriwhiria a EH36 mō ngā taiao moana tino uaua:

• Ngā Kaipahū Hukapapa

• Ngā kaipuke o te akomanga Arctic me te polar

• Ngā papaaho moana i roto i ngā āhuarangi hukapapa

• Ngā waka tūnga hihiri

• Ngā pūnaha FPSO me ngā pūnaha raro moana

• Ngā wāhi hanganga pānga nui e tata ana ki te ihu o te waka

He tino pai te mahi a EH36 i raro i te makariri nui me te ahotea nui.

AH36 vs DH36 vs EH36: Ko tēhea te mea pai mō tāu kaupapa

Ko te kounga maitai pai rawa atu e whakawhirinaki ana ki te taiao mahi, ngā whakaritenga hanganga, me ngā ture a te hapori whakarōpū.

Kōwhiria te AH36 mēnā

• Ka mahi te kaipuke i roto i ngā wai māhana, i ngā wai ngawari rānei

• Kāore ngā wāhanga hanganga e pāngia e te makariri nui

• Ko te kaupapa e arotahi ana ki te hangahanga utu-whai hua

• Kāore te tono i te tino hira mō te pakari i te pāmahana iti

Kōwhiria te DH36 mēnā

• Ka taea e te kaipuke te mahi i roto i ngā āhuarangi makariri

• He nui ake te pakari o ngā wāhanga i te AH36

• Kei te hanga waka koe i ngā rohe waenga-whānui, i ngā waka taiao-whakauru rānei

• He nui ake ngā kawenga hanganga, kei roto rānei i ngā wāhi tairongo

Kōwhiria a EH36 mēnā

• Ka whakahaerehia te kaipuke i roto i ngā wai Arctic

• Ko te mahi e hiahiatia ana mō te kaupapa he tino iti te pāmahana.

• Kei te hanga waka koe mō te akomanga hukapapa, mō te takutai moana, mō te moana hohonu rānei

• E whakaatu ana ngā tuhi a te rōpū whakarōpū i ngā rauemi E-grade

Ko te EH36 te mea tino pai mō te haumaru i roto i te hangarau moana i te makariri.

Ngā Whakaritenga a te Rōpū Whakarōpū

Me whakamanahia ngā māka katoa e ngā rōpū pēnei i:

• ABS

• LR

• Te Tari Whakahaere Hauora (DNV)

• BV

• CCS

Ko ngā whakaritenga noa ko:

• Tātaritanga matū

• Ngā whakamātautau kume

• Ngā whakamātautau pānga Charpy

• Whakamātautau Ultrasonic

• Manatoko maimoatanga wera

• Te whai i te aru me te tā

Ko EH36 te mea e tino tirotirohia ana nā te mea he uaua te mahi i te pāmahana iti.

Te Maimoatanga Wera me te Tukatuka

Ka taea te tuku i ngā pereti taumata-moana penei:

• Kua hurihia

• Kua Whakaōritea

• Whakahaere-hurihurihia

• TMCP tukatukahia e te wera-mīhini

E whakamahia whānuitia ana te TMCP mō te DH36 me te EH36 nā te mea ka whakarei ake i te kaha me te pakari, me te pupuri tonu i te āheinga whakarewa me te whakaiti i te hiahia mō ngā wāhanga matotoru.

Whakataurite i te Āheinga Whakarewa

He pai te āheinga whakarewa o ngā momo e toru, engari me āta whakahaere te EH36 i:

• Whakauru wera

• Ngā āhuatanga whakamahana-mua

• Ngā pāmahana i waenganui i ngā ara

Nā te kaha ake o te hanganga o te koranu me ngā whakaritenga pakari teitei ake i puta ai tēnei.

Ngā Whakaaro mō te Utu

I te nuinga o te wā:

• Ko te AH36 te mea tino ohanga

• He utu tika te DH36

• Ko te EH36 te mea tino utu nui nā te mea he kaha ake ngā whakaritenga mō te pakari me te kaha ake o ngā whakaritenga mō te tiwhikete.

Mā te whiriwhiri i te māka tika ka āwhina i te whakapai ake i te utu o te kaupapa me te kore e whakararu i te haumaru.

Ngā Wero Noa i te Kōwhiringa Māka

1. Te Hē o te Whakaritenga i waenganui i ngā Whakaritenga Tuhi me te Hokonga

Ko ētahi tuhi me whakamahi i te E-grade, engari ka hē te hoko rauemi A-grade a ngā wāhi hanga kaipuke.
Otinga: Tirohia anō ngā ture a te rōpū whakarōpū i mua i te tono.

2. Whakakapinga Hē

Kāore e whakaaetia te whakakapi i te EH36 ki te AH36 i ngā rohe makariri.
Otinga: Me whai i te whakarōpūtanga pakari kia tino tika.

3. Ngā tuhinga kāore i oti

Ka whakakorehia te MTC, ngā tuhinga whakamātautau rānei mēnā ka ngaro.
Otinga: Hokona mai i ngā kaiwhakarato pono pēnei i asakysteelme te whai i te katoa me te tiwhikete.

4. Te Kore o te Whakamātautau Pāmahana-Iti

Ka pekehia e ētahi mira ngā whakamātautau -20°C, -40°C rānei mēnā kāore i te tohua.
Otinga: Me whakarite kia mārama te whakamārama i ngā whakaritenga pāmahana pānga.
