Ngā Hononga Paipa Rino me te Kowiri tira Buttweld
Ko ngā hononga paipa Buttweld he tuke roa te radius, he whakaiti porowhita, he whakaiti āhuarangi me ngā Tī me ētahi atu. He wāhanga nui o te pūnaha paipa ahumahi ngā hononga maitai kore waikura me te maitai waro kua whakarewahia hei whakarerekē i te ahunga, hei wehe i te peka, hei hono ā-mīhini rānei i ngā taputapu ki te pūnaha. Ka hokona ngā hononga Buttweld i roto i ngā rahi paipa ingoa me te rārangi paipa kua tohua. Ko ngā ine me ngā manawanui o te hononga BW kua tautuhia e ai ki te paerewa ASME B16.9.
He maha ngā painga o ngā hononga paipa whakapiri-tua pērā i te maitai waro me te maitai kore-waikura ki te whakataurite ki ngā hononga miro me ngā hononga whakapiri-tua. Ko ngā mea o muri ake nei e wātea ana tae atu ki te 4-inihi te rahi ingoa, ko ngā hononga whakapiri-tua kei te wātea i ngā rahi mai i te ½” ki te 72”. Ko ētahi o ngā painga o ngā hononga whakapiri-tua ko;
He kaha ake te hononga mā te hononga whakarewa
Ka whakanui ake te hanganga whakarewa tonu i te kaha o te pūnaha paipa
Mā ngā hononga whakarewa-putanga me ngā whakaritenga paipa e rite ana, ka rere pai te rere o roto i te paipa. Mā te whakarewatanga uru katoa me te whakaurunga tika o te Tuke LR 90, te Whakaiti, te Whakaiti Kōtahi me ētahi atu, ka taea te whakawhiti mārire mā te hononga paipa kua whakarewaina.
He pito piko ngā pito o ngā hononga paipa whakapiripiri katoa e ai ki te paerewa ASME B16.25. Mā tēnei ka taea te hanga i te hononga whakapiripiri katoa, me te kore e hiahiatia he whakaritenga tāpiri mō te hononga whakapiripiri.
Ko ngā hononga paipa whakarewa-puku e wātea ana i roto i te maitai waro, te maitai kore waikura, te koranu nikara, te konumohe me ngā rauemi hua teitei. Kei te wātea ngā hononga paipa maitai waro whakarewa-puku hua teitei i roto i te A234-WPB, A234-WPC, A420-WPL6, Y-52, Y-60, Y-65, Y-70. Kua whakamahanahia ngā hononga paipa WPL6 katoa, ā, he hototahi ki te NACE MR0157 me te NACE MR0103.
