Ngā Paerewa ASTM mō te Paipa Rino Waro
Kua whakawhanakehia e te American Society for Testing and Materials (ASTM) he maha ngā paerewa mō ngā paipa maitai waro, e whakamārama ana i te rahi, te āhua, te hanganga matū, ngā āhuatanga hangarau me ētahi atu whakaritenga hangarau o ngā paipa maitai. Ko ngā paerewa ASTM e whai ake nei mō ngā paipa maitai waro:
1. Ngā Paipa Rino Waro Kore Tuitui
ASTM A53: E pā ana ki ngā mea pango me te kore hononga i whakarewahia,ngā paipa maitai whakarewa wera-tuku, e whakamahia whānuitia ana mō ngā kaupapa hanganga, ngā pūnaha paipa, me ētahi atu. E toru ngā taumata o tēnei paerewa: A, B, me C e ai ki te matotoru o te pakitara.
ASTM A106: He paipa maitai waro kore-tuitui e tika ana mō te mahi pāmahana teitei, kua wehea ki te Wāhanga A, B, me te C, e whakamahia ana i roto i ngā paipa tuku hinu, hau māori me ngā ahumahi matū.
ASTM A519: E pā ana ki ngā pae maitai waro tui kore tino tika me ngā paipa mō te miihini, me ngā whakaritenga manawanui ā-ahu tino pakari.
2. Ngā Paipa Rino Waro i Whakarewahia
ASTM A500: E pā ana ki ngā tapawhā whakarewa matao me te tapawhā kore hononga,tapawhā riteme ētahi atu paipa maitai hanganga āhua, e whakamahia whānuitia ana i roto i ngā hanganga whare.
ASTM A501: E pā ana ki ngā paipa maitai hanganga tapawhā, tapawhā hāngai me ētahi atu āhua kua hurihia ki te wera me te kore hononga.
ASTM A513: E pā ana ki te hikongā paipa maitai porowhita kua whakarewaina, e whakamahia whānuitia ana mō ngā mahi miihini me ngā mahi hanganga.
3. Ngā paipa maitai waro mō ngā kohua me ngā whakamahana nui
ASTM A179: E pā ana ki ngā paipa kōhua maitai waro-iti e tōia ana i te matao, e tika ana mō ngā tono mamaoa pēhanga teitei.
ASTM A210: E pā ana ki ngā paipa pūwero maitai waro kore hononga, e whā ngā taumata: A1, A1P, A2, me te A2P, e whakamahia ana mō ngā pūwero pēhanga reo me te pēhanga iti.
ASTM A335: E pā ana ki ngā paipa ratonga pāmahana-tiketike maitai koranu ferritic kore hononga, kua wehea kia maha ngā momo, pēnei i te P1, P5, me ētahi atu, e tika ana mō ngā paipa pāmahana-tiketike i roto i ngā ahumahi petrochemical me te hiko.
4. Ngā paipa maitai waro mō ngā puna hinu me te hau
ASTM A252: E pā ana ki te pewa tuitui porowhita i raro i te waingā paipa maitai kua whakarewainamō ngā pou, e whakamahia whānuitia ana i roto i te hanganga papaaho tai.
ASTM A506: E pā ana ki ngā paipa maitai hanganga iti-koranu kaha-teitei, e tika ana mō te hanga taputapu mara hinu me te hau.
ASTM A672: E pā ana ki ngā paipa maitai silicon waro konupora kaha teitei, e tika ana mō ngā tono e hiahia ana kia kaha ake.
API Spec 5LAhakoa ehara i te paerewa ASTM, he paerewa e whakaaetia ana e te ao mō ngā paipa rino mō ngā paipa hinu me te hau, e kapi ana i ngā momo paipa rino waro maha.
5. Ngā paipa maitai waro mō ngā kaupapa motuhake
ASTM A312: E pā ana ki ngā paipa kore-waikura me ngā paipa whakarewa. Ahakoa he mea hanga mō te kowiri tira te nuinga, kei roto hoki ētahi whakaritenga maitai waro.
ASTM A795: E pā ana ki ngā pereki maitai waro me te maitai koranu, ngā pereki porowhita me ā rātou hua i hangaia mā te maka me te hanga tonu, e tika ana mō ngā mara ahumahi motuhake.
Me pēhea te whiriwhiri i te paerewa ASTM tika
Ko te whiriwhiri i te paerewa ASTM tika e whakawhirinaki ana ki ngā whakaritenga tono motuhake:
Taiao whakamahi: Whakaarohia ngā āhuatanga pēnei i te pāmahana whakahaere, ngā āhuatanga pēhanga, me te noho mai o ngā mea waikura.
Ngā āhuatanga hangarau: Whakatauhia te kaha tuku iti rawa e hiahiatia ana, te kaha kume me ētahi atu tohu matua.
Te tika o ngā āhuatanga: Mō ētahi mahi miihini, mahi huihuinga rānei, me whai tikanga whakahaere kia tino tika te whānui o waho me te matotoru o te pakitara.
Te maimoatanga mata: Ahakoa e hiahiatia ana te whakawairakau wera, te peita me ētahi atu momo maimoatanga ārai-waikura.
