Utu Pai mo te Hot Rolled API Casing Carbon Alloy Steel Seamless Round Pipe mo te Kohua
Whakaahuatanga Poto:
20G putorino maitai tui ko te waro hanganga maitai teitei, rauemi kōhua, te ihirangi waro o 0.17-0.24%, kaha tensile o 410Mpa, ira tuku 230-250Mpa.Ko ta matou hanga matua o te maitai, ka taea e matou te whakarato 20G Seamless pipe me te kounga teitei me te utu whakataetae.I konei hei whakamohio ki a koe ki a maatau paipa 20G paipa koretake nga ahuatanga matū me nga taonga miihini.
I whakatapua ki te whakahaere kounga me te kamupene kaihoko whakaaro nui, kei te watea a maatau kaimahi mohio ki te korero mo o whakaritenga me te tino pai ki nga kaihoko mo te utu pai mo te Hot Rolled API Casing Carbon Alloy Steel Seamless Round Pipe mo te Boiler, I runga i te kounga teitei me te utu hoko whakataetae , ko matou te rangatira o te maakete o naianei, kia mohio koe kaua e tatari ki te whakapiri mai ki a maatau ma te waea pūkoro, imeera ranei, mena kei te pirangi koe ki tetahi o a maatau hua.
I whakatapua ki te whakahaere kounga me te kamupene kaihoko whakaaro nui, kei te waatea nga mema o nga kaimahi mohio ki te korero mo o korero me te whakarite kia tino koa nga kaihoko.Haina Paipa Korekore me te Paipa Maamaa Alloy, Ka whakapau kaha tonu matou ki te maakete me te whakawhanaketanga hua me te hanga i tetahi ratonga pai ki to taatau kaihoko ki te hanga i te wa kei te heke mai.Kia mohio koe ki te whakapiri mai ki a matou i tenei ra ki te mohio me pehea e mahi tahi ai matou.
