-316L Kowiri tiraHe pai ake te ātete ki te waikura o tēnei momo rino kore waikura iti-waro o te 316, ā, he maha ngā wā ka whakamahia i roto i ngā taiao tino waikura. Nā te iti o te ihirangi waro, he tino pai mō ngā tono whakawhiti wera.
- 321 Kowiri tiraNā te nui o te titanium i tāpirihia, he tino ātete te maitai kore waikura 321 ki te waikura intergranular, ā, he pai mō ngā tono e pā ana ki ngā pāmahana teitei.
Ko tētahi atu mea nui hei whakaaroaro māu i te wā e whiriwhiri ana i ngā paipa kowiri tira moana ko te rahi me te matotoru o te pakitara o te paipa. Ko te rahi o te ngongo ka whakawhirinaki ki te whakamahinga motuhake me te rere e hiahiatia ana. Me āta whiriwhiri te matotoru o te pakitara kia tu atu ai i ngā pēhanga me ngā āhuatanga ka pā ki te paipa.
Hei tāpiritanga, he mea nui te ātete ki te wera o ngā paipa, inā koa mō ngā whakamahinga moana e pā ana ki ngā whakawhiti wera. Me hanga ngā ngongo whakawhiti wera kowiri tira ki ngā rauemi e kaha ana ki te tu atu i ngā pāmahana teitei me te kore e whakararu i tōna hanganga.
Hei whakamutunga, mō ngā whakamahinga moana e pā ana ki ngā āhuatanga cryogenic, he mea nui kia whiriwhiria ngā ngongo kowiri tira e mau tonu ana te pakari me te ngāwari ahakoa i roto i ngā āhuatanga tino makariri. Ko ngā ngongo kowiri tira pakari cryogenic kua hangaia kia mau tonu tōna kaha i roto i ngā pāmahana i raro i te kore, kia pai ai te mahi me te haumaru.
Mō te whiriwhiri paipa kowiri tira moana, e whakahīhī ana a Shandong zhongao steel Co., Ltd. ki te tuku i tētahi kōwhiringa whānui e tutuki ana i ngā paerewa ahumahi teitei rawa atu. Kua whiriwhiria marietia ā rātou paipa kowiri tira moana kia pai ai te ātete ki te waikura, te roa me te pono mō ngā momo mahi moana.
