ASTM A53 Gr.BKo tētahi o ngā paerewa paipa maitai i hangaia e te American Society for Testing and Materials (ASTM). E whai ake nei he whakataki taipitopito mō te paipa maitai kore hononga A53 Gr.B:
1. Tirohanga Whānui
Paipa maitai kore hononga ASTM A53 Gr.B. I roto i ngā paerewa paipa maitai i hangaia e te American Society for Testing and Materials (ASTM), e rua ngā taumata o te ASTM A53, ko A me B. Ko te ASTM he huinga paerewa o Amerika. Ko te paerewa Hainamana e rite ana mō te A53A ko GB8163, he mea hanga ki te maitai Nama 10, ā, ko te paerewa Hainamana e rite ana mō te A53B ko GB8163, he mea hanga ki te maitai Nama 20. E whakamahia whānuitia ana mō ngā paipa whānui.
2. Te tukanga hanga
ASTM A53 Gr.BKo te hangarau paipa tuimotu te nuinga o te wā e whakamahia ana i roto i te tukanga hanga. Ko te hangarau paipa tuimotu e pā ana ki te tukanga tukatuka i te pereki hei paipa rino he matotoru pakitara ōrite me ngā mata o roto me waho maeneene mā roto i ngā tukanga pēnei i te poka pereki, te hurihuri, me te whakawhānui i te diameter. Ahakoa e whakaaetia ana e te paerewa ASTM A53 te whakamahi i te hangarau paipa whakarewa hei hanga paipa rino, i roto i te hanga oASTM A53 Gr.B, ko te hangarau paipa tui kore te tikanga whakaputa matua.
3. Ngā Āhuatanga o te Hua
He matotoru te pakitara me te tino tika o te diameter o waho: He tino tika te matotoru o te pakitara me te diameter o waho o te paipa tui ASTM A53 Gr.B, ā, ka taea te whakatutuki i ngā hiahia o ngā hanganga matatini.
Te ātete kaha ki te pēhanga me te ātete ki te waikura:ASTM A53 Gr.BHe ātete teitei te paipa tuimotu ki te pēhanga me te ātete ki te waikura, ā, ka taea te mahi pumau mō te wā roa i roto i ngā taiao uaua.
Whānui te whakamahinga: He pai te paipa ASTM A53 Gr.B tui kore mō ngā pūnaha paipa hei kawe i te hau, te wai me ētahi atu wai, tae atu ki ngā whakamahinga ahumahi, te tuku wai me ngā pūnaha whakamahana.
4. Awhe paerewa
E pā ana te paerewa ASTM A53 GRB ki ngā paipa maitai waro honohono tika (whakarewa) me te kore hononga, e kapi ana i ngā momo diameter o waho, matotoru o te pakitara me ngā tikanga tukatuka. E ai ki ngā whakaritenga tono rerekē, ka taea hoki te whakakanapa, te whakararangi, te pani, me ētahi atu paipa paerewa ASTM A53 GRB hei whakapai ake i tō rātou ātete ki te waikura me te roa o te mahi.
