ASTM A53Ko te paerewa ko te American Society for Testing and Materials. Ka hipokina e te paerewa ngā momo rahi me ngā matotoru o ngā paipa, ā, ka pā ki ngā pūnaha paipa e whakamahia ana hei kawe i ngā hau, ngā wai me ētahi atu wai. Ko ngā paipa paerewa ASTM A53 e whakamahia whānuitia ana i roto i ngā wāhi ahumahi me ngā wāhi miihini, tae atu ki te ahumahi hanga mō te tuku wai, te whakamahana me ngā pūnaha hauhautanga.

E ai kiASTM A53e ai ki te paerewa, ka taea te wehewehe i ngā paipa kia rua ngā momo: Momo F me te Momo E. Ko te Momo F he paipa tuimotu, ā, ko te Momo E he paipa hiko whakarewa. Me whakamahana ngā momo paipa e rua kia tutuki ai ngā āhuatanga miihini me te hanganga matū i ngā whakaritenga paerewa. Hei tāpiri, me tutuki ngā whakaritenga mata o te paipa ki ngā whakaritenga o te paerewa ASTM A530/A530M kia pai ai tōna āhua.

Ko ngā whakaritenga hanganga matū mō ngā paipa paerewa ASTM A53 koia ēnei: ​​kaua e neke ake i te 0.30% te nui o te waro, kaua e neke ake i te 1.20% te nui o te konupora, kaua e neke ake i te 0.05% te nui o te whānariki, kaua e neke ake i te 0.045% te nui o te konupora, kaua e neke ake i te 0.40% te nui o te konukōmiuma, ā, kaua e neke ake i te 0.40% te nui o te nikara, kaua hoki e neke ake i te 0.40% te nui o te parahi. Mā ēnei here hanganga matū ka mau te kaha, te pakari me te ātete ki te waikura o te paipa.

Mō ngā āhuatanga ā-pūkaha, e hiahiatia ana e te paerewa ASTM A53 kia kaua e iti iho i te 330MPa me te 205MPa te kaha kume me te kaha tuku o ngā paipa. Hei tāpiri, he whakaritenga anō hoki mō te tere whakaroa o te paipa kia kore ai e pakaru, e rerekē rānei te āhua i te wā e whakamahia ana.

Haunga te hanganga matū me ngā āhuatanga miihini, kei roto hoki i te paerewa ASTM A53 ngā ture taipitopito mō te rahi me te kounga o te āhua o ngā paipa. Kei waenga i te 1/8 inihi ki te 26 inihi te rahi o ngā paipa, me ngā momo whiringa matotoru pakitara. Ko te kounga o te āhua o te paipa me whai mata maeneene, kāore he waikura, he pakaru, he hapa rānei kia kore ai e turuturu, e pakaru rānei i te wā e tāuta ana, e whakamahia ana rānei.

I te nuinga o te wā, he paerewa nui te paerewa ASTM A53 mō ngā paipa maitai waro. E kapi ana i ngā whakaritenga mō te hanganga matū, ngā āhuatanga miihini, ngā rahi me te kounga āhua o ngā paipa. Mā ngā paipa i hangaia kia rite ki tēnei paerewa ka taea te whakarite i te kounga pumau me te mahi pono, ā, he pai hoki mō ngā pūnaha paipa i roto i ngā momo ahumahi me ngā mahi hanga. He mea nui te whakatakotoranga me te whakatinanatanga o ngā paerewa ASTM A53 hei whakarite i te mahi haumaru o ngā paipa me te whakatairanga i te kounga o te hanganga kaupapa.
