Ngongo Rino Koranu Korekore AISI 4145H
Whakaahuatanga Poto:
Ka tukuna e mātou ngā paipa maitai koranu matao 4145H, he kaha teitei, he pakari rawa, ā, he ātete ki te ngenge. He pai mō te keri hinu me te hau, ngā mīhini taumaha, me ngā ahumahi motuka.
Paipa Kore-Tuitui Rino 4145H:
Ko te Paipa Kore-Tuinga Rino 4145H he paipa rino koranu chromium-molybdenum kaha-teitei e mōhiotia ana mō tōna pakari pai, te ātete ki te kakahu, me te kaha ngenge. I te nuinga o te wā ka tukuna i roto i te āhua kua tineihia me te whakamahana hei whakarei ake i ōna āhuatanga miihini, tae atu ki te kaha kume me te kaha tuku. He whānuitia te whakamahinga o tēnei paipa kore-tuinga i roto i te keri hinu me te hau, ngā mīhini taumaha, me ngā tono motuka, e hiahiatia ana te pakari me te ātete pānga. I hangaia kia rite ki ngā paerewa ASTM A519, ka whakamatautauria ngā paipa kore-tuinga 4145H kia tika ai te kukume matao me te whakamātautau kore-whakangaro hei whakarite i te tika me te pono o ngā āhuatanga i roto i ngā taiao uaua.
