Mō ngā mahi hanga whare me ngā hanganga, he mea nui te whiriwhiri rauemi hei whakarite i te haumaru, te pakari, me te mahi. Ko tētahi rauemi e tino whakautehia ana i roto i te umanga ko ASTM A252 Rino Tau 3. He mea tino nui tēnei whakatakotoranga mō te hanga i ngā puranga paipa e whakamahia ana i roto i ngā turanga hohonu, ā, he mea nui ēnei mō ngā kaupapa hanga maha.
Ko te ASTM A252 he paerewa whakatakotoranga i whakawhanakehia e te American Society for Testing and Materials (ASTM) e whakamārama ana i ngā whakaritenga mō te whakarewa me te hononga-kore.paipa maitaingā pou. Ko te taumata 3 te taumata kaha teitei rawa atu i roto i tēnei whakatakotoranga, me te kaha whakaputa iti rawa o te 50,000 psi (345 MPa). Nā tēnei ka tino pai mō ngā tono e hiahia ana ki te kaha kawe kawenga nui me te ātete ki te whakarerekētanga.
Ko tētahi o ngā painga matua o te ASTM A252 Grade 3 ko tōna āheinga whakarewa pai rawa atu, e āhei ai te hanga me te tāutanga whai hua. Kei roto i te hanganga matū o tēnei maitai ngā huānga pēnei i te waro, te konupūmā, me te silicon, e whai wāhi ana ki tōna kaha me tōna pakari. Hei tāpiri, ka taea e te rauemi te tu atu ki ngā āhuatanga taiao uaua, e pai ai mō te whakamahi i roto i te moana me ētahi atu taiao wero.
Ina hoki, he maha ngā wā ka whakamahia te ASTM A252 Grade 3 i roto i te hanganga o ngā piriti, ngā whare, me ētahi atu kaupapa hanganga e hiahia ana ki ngā turanga hohonu. Ko tōna kaha ki te tautoko i ngā kawenga taumaha me te pupuri tonu i te hanganga pai he mea nui ki te roa o te ora me te haumaru o ēnei hanganga.
Hei whakarāpopototanga,ASTM A252 Tau 3He rauemi matua te maitai mō te umanga hanga, e whakarato ana i te kaha me te pakari e hiahiatia ana mō ngā tono turanga hohonu. Mā te mārama ki ōna āhuatanga me ōna painga ka āwhina i ngā kaihangarau me ngā kaimahi kirimana ki te whakatau whai whakaaro i te wā e whiriwhiri ana i ngā rauemi mō ā rātou kaupapa, ā, ka hua ake he hanganga haumaru ake, he hanganga pono ake.
