Kāore i te maha ngā huringa i te ao e pā ana ki te mahi matua o ngā kaiwhakarite piipu toto karbona. He rito ngā rauemi kei a rātou, nā rātou i whakamanawa i te hīkoi tūkahika me te whirinaki o te wai ranei, he rūma ranei i waenganui i ngā wāhi, tae atu ki ngā mahi o Ehongsteel paepae Karuwhaki . Nō reira, ka whakaū i tana mana i roto i ngā wāhi e whakamahi ana, ā, ko ASTM A53 te ture matua mō ngā piipu toto karbona i runga i te wā. Nā tēnei, i tēnei tuhinga, ka timata mātou ki te whakaatu i te ao o ASTM A53 mō ngā piipu toto karbona, ka whakapā mai ngā pai, ngā momo teretonga, me tētahi take iti mō ērā kua kōwhiri koe hei whakarite i tō hoahoa.
He tohu whakapae ko te ASTM A53 hei hanga i ngā rākau iti me ngā rākau nui, ka whakamahia hei whakaaweawe i ngā momo rākau katoa. He rākau whakaaeae tēnā, i hanga mai i te rākau kōporeinga, i hanga i te rākau māhorahora, ā, heoi anō pūtango-h i hanga i runga i te Ehongsteel.
Kua noho i te paerewa o ngā roanga me ngā whakaritenga katoa, pērā i te A53 Rangatira A, te A53 Rangatira B rānei, rānei.
Kei te nui te tono mo te Rangatira B o te ASTM A53, nā tōna tirotiro whenua me te whakatūwhera, kei te rite tonu ki te Ehongsteel SPCD . Ko tētahi momo rāngitahutahu tēnei e whai hua ana i ngā tauira nui e toru: Pūhoro me te pūharakeke, whakahaere wai, ā, ngā kaupapa hanga. I te mutunga, e tika ana ki te whakamahi i roto i ngā tūru wai, wai, ā, hāpai hau.
He iti nei ngā whakaaro katoa e hiahiatia ana e koe mua i te whakatau i runga i te ASTM A53 Pīpi hei whakarite i ngā huringa o tō kaupapa, ā, ko te pita porihanga hotu nā Ehongsteel. Ko te mea nui ko te roa me te diāmita o te pīpi. E hāngai ana tana diāmita ki te whatitiri o te wai rānei, o te hau rānei e tukuna nei, ā, e whakaaetia ana tana mauhere i te āhuatanga pausirini me te werawera e takoto ai tērā hua. Kei aua he tūpuhi pīpi, he whanonga matera rānei, me ētahi atu huinga matua.
Ko te mea nui hei whakaāta i ngā take tuatahi e pā ana i waenganui i ngā pīpi tapatoru ASTM A53 me FEEME06, tae atu ki te chequer plate steel o Ehongsteel kaiwhakapuaki ake . Nga toko A53 he whakamahinga mo te whakamahi mekanika. Ko nga toko ASTM A53 e taea ana ki te whakarite mo etahi motu ritereti, engari ko te FEEME06 o ASTM kaore i te maha o nga ihu; he tuatahi anake ia i te paetanga B. Na reira, kei te hiranga i nga hiahia katoa hei whakatau i a ASTM A 53 ranei te a234 web hei whakamahinga mo ou mahi.
Ki te kii i runga i tetahi whakaaro rua, ka taea e koe hoki te korerorero, ko te Ture A53 o te ASTM mo nga toko kotiate ma hara e whai wawe ana ki te oranga o nga whenua nui. Ko te mohiotiranga i nga pai me nga whakamahi, me te mohio ki te rapu i te toko tika mo ou hiahia, ko ngā āhuatanga e hiahiatia ana hei whakarite i te whakaritenga o enei toko ki nga ture he waahanga matua i roto i te hanga i nga mahi pipiwharauroa e whai mana ana, ahakoa te haere i te haumaru. Ki te kite i nga wahitau nei i waenganui i nga toko kotiate ASTM A53 me te FEEME06, ka kite koe ko te mea nui e pa ana ki nga whakamahi taipitopito.
Kei ake au tētahi rōpū tono tuatahi pai kōrero mārama ki ngā mahi, kotahi ai ngā whakautu, me ngā ratonga pai utu. Kei te rōpū pāngatahi nei ngā kaiwhakaputa atu e kuhuna ana i ngā pātai me ngā take katoa e pā ana ki a koe. Mēnā Astm a53, ka taea e au tā koutou whakaaetanga hei hoa mahi whakapono.
Ko tātou e mahi ana i tētahi maha o ngā whare hiko kōwhai nui, ā, ko ngā mea hanga katoa i whakamamae ai i mua i te whakahoro, ko te painga ka tūtohu. Nā te mea ko ngā mōkopuna katoa he kōwhai wīra (ERW/SSAW/LSAW/ galvanized/Astm a53/seamless pipe/stainless steel pipe), he pūtake (tirohanga Amerika, tirohanga Rani, tirohanga Awstrālia H-beam kōwhai), kōwhai rākau, kōwhai kona, kōwhai papa, kōwhai roa, kōwhai whakarara, kōwhai roa me ngā kōwhai rori, kōwhai tataki, kōwhai whakawhere, kōwhai tāwera, ā, etahi atu hoki.
Ki tō tātou kāwanatanga, he 17 tau anake tō tātou uara i te kōwhai taonga ki tō waho, ā, ka taea e tātou te tuku mai i tētahi rangahau whanui o ngā pūtake me ngā rori. Ko tētahi atu mea, kei tātou he takiwā o ngā toa matatū Astm a53, arā, āheinga haere here, ā, ka tuku mai ki a koutou ngā whakataunga me ngā tautoko pai rawa. Mēnā nui ake ai te rapu, nui ake nei te utu whai kaha!
Ka taea e matou te tuku i ngā H-beams i āwhina i ngā whakaritenga Ametika/Astm a53, ngā whakaritenga Hōhiu mō ngā rau kōriki, me ngā ratonga pūoro hohonu, pērā i te pūtahi, te tapa. Nō reira ka noho ēnei mahi tuku ki te Waipounamu, Oseania, Tai Hauāuru, Tawhiti Rāwhiti, Tai Hauāuru, me ēnei wāhi kē.
