Paerewa Paipa ASTM A53: Te Aratohu Whakamahinga Whānui Ko ngā paipa maitai ASTM A53 tētahi o ngā paerewa e whakamahia whānuitia ana mō ngā paipa maitai o te ao i roto i te mara o ngā paipa me te hanga. E toru ngā momo: LSAW, SSAW, me te ERW, engari he rerekē ā rātou tukanga hanga, ā, he rerekē hoki te whakamahinga.
1. Astm A53 LSAPaipa Rino W(Te Whakarewatanga Pewa Ruku Roa)
Ka hangaia te paipa LSAW mā te piko i te pereti maitai ki te roa, kātahi ka whakarewahia, ā, ko te hononga whakarewa kei roto, kei waho hoki o te paipa! He pai ngā paipa LSAW, he maitai kounga teitei, mō ngā mahi hinu me te hau pēhanga teitei. Nā te kaha o ngā whakarewa me ngā pakitara matotoru, he pai ēnei paipa mō ngā paipa hinu me te hau pēhanga teitei, me ngā mahi moana.
2. Astm A53SSAWPaipa Rino(Whakapiripiri Porowhita Rukuhia)
Ka hangaia ngā paipa SSAW mā te whakamahi i te tikanga whakarewa pewa hurihuri. Mā te whakarewa porowhita ka taea te whakaputa hua ohanga, ā, he mea tino pai mō ngā puna wai pēhanga-waenga ki te iti, mō ngā whakamahinga hanganga rānei.
3.Astm A53ERWPaipa Rino(Whakapirihia te Ātete Hiko)
Ka hangaia ngā paipa ERW mā te whakarewa ātete hiko, nō reira he iti noa te porowhita piko e hiahiatia ana mō te piko i roto i te whakaritenga whakarewa, e āhei ai te hanga paipa he iti te diameter me ngā whakarewa tika, he iti noa te utu whakaputa mō ēnei paipa. Ko te nuinga o te wā ka whakamahia i roto i te hanganga mō ngā anga hanga, ngā ngongo miihini, me te kawe wai i te pēhanga iti.
Ko ngā rerekētanga matua e whai ake nei:
Tukanga WhakarewaKo ngā tukanga LSAW/SSAW he whakarewa pewa ruku, ko te ERW he tukanga whakarewa ātete hiko.
Te whānui me te matotoru o te pakitaraHe nui ake te diameter o ngā paipa LSAW me ngā pakitara matotoru ake i ērā o ngā paipa SSAW me ERW.
Te Whakahaere Pēhanga: LSAW > ERW/SSAW.
