"Paipa Koranu Rino HTASTM A335 GR P22- SCH 80. Ko te "ASME B36.10 PLAIN ENDS (QUANTITIES UNIT: M)" he huinga whakatakotoranga hangarau e whakaahua ana i ngā paipa maitai koranu. Me tātari takitahi tātou:

PAIPA KORANU RINO HT:
Ko te tikanga o te "PAIPA" he paipa, ā, ko te tikanga o te "RINO KONU" he maitai konumohe. Ko te maitai konumohe he maitai kei roto i tētahi, neke atu rānei o ngā huānga konumohe (pērā i te chromium, te molybdenum, te tungsten, me ētahi atu) ā, he tino pai ngā āhuatanga pērā i te ātete ki te pāmahana teitei, te ātete ki te waikura me te kaha.

Ko te kupu "HT" e pā ana ki ngā whakaritenga pāmahana teitei, e tohu ana he pai tēnei maitai paipa mō ngā taiao pāmahana teitei.

ASTM A335 GR P22:
He whakaahuatanga tēnei mō te paerewa me te kounga o ngā rauemi paipa.

ASTM A335He paerewa tēnei nā te American Society for Testing and Materials (ASTM) i whakawhanake mō ngā paipa maitai koranu kore hononga, inā koa mō ngā taiao pāmahana teitei me te pēhanga teitei.
Ko te GR P22 te taumata rauemi motuhake i raro i tēnei paerewa, ko te "P22" te tohu mō te hanganga matū me ngā whakaritenga mahi o te rauemi paipa. Ko te maitai koranu P22 he maha ngā huānga chromium (Cr) me te molybdenum (Mo), he kaha pāmahana teitei me te ātete ki te waikura, ā, he pai mō ngā taiao pāmahana teitei.
SCH 80:
E pā ana tēnei ki te matotoru o te pakitara o te paipa, ā, ko "SCH" te whakarāpopototanga o "Schedule".

Ko te tikanga o te SCH 80 he matotoru te pakitara o te paipa, ā, ka taea e ia te tu atu i te pēhanga nui o roto. Mō ngā paipa SCH 80, he nui ake te matotoru o tōna pakitara i roto i ngā paipa he rite te diameter, ka taea ai te whakanui ake i tōna kaha ki te pupuri i te pēhanga me te ātete ki te pānga.
ASME B36.10:
He paerewa tēnei i whakawhanakehia e te American Society of Mechanical Engineers (ASME) e tohu ana i te rahi, te āhua, te manawanui, te taumaha me ētahi atu whakaritenga o ngā paipa maitai. Ko te B36.10 e aro ana ki te diameter o waho, te matotoru o te pakitara me ētahi atu tawhā o ngā paipa kore hononga maitai waro me te maitai koranu, me ngā paipa whakarewa hei whakarite i te paerewa me te ōritetanga o ngā hua paipa.

NGĀ MUTUNGA MAHINGA:
Ko te "Plain Ends" e pā ana ki ngā paipa kāore he pito miihini, kāore hoki he pito hononga, he mata tapahi maeneene te nuinga. Ki te whakatauritea ki ngā paipa he hononga miro, he hononga flanged rānei, ka whakamahia ngā paipa pito noa i ngā mahi e hiahiatia ana he hononga whakarewa.

NGĀ RAHI WĀHANGA: M:
E tohu ana tēnei ko te waeine ine mō te hua ko "mita", arā, ko te nui o te paipa ka inehia i roto i ngā mita, ehara i te mea he wahi, he waeine rānei.

Ko te paipa e whakaahuatia ana i roto i tēnei whakaahuatanga he paipa maitai koranu pāmahana-teitei e tutuki ana i te paerewa ASTM A335 GR P22, ko te matotoru o te pakitara he SCH 80, ā, e tutuki ana i te paerewa rahi ASME B36.10. He papatahi ngā pito o te paipa (kāore he miro, he here rānei), ka inehia te roa i roto i ngā mita, ā, he pai mō ngā pūnaha paipa i roto i ngā taiao pāmahana-teitei, pēhanga me te waikura.
