ASTM A106 A53 Gr.B A179 20G Paipa Uamea Kabone Su'esu'e Ma'alili Toso Uamea Su'e
Fa'amatalaga Puupuu:
20G paipa uʻamea seamless o se uʻamea fausaga maualuga carbon, mea fauvela, le anotusi carbon o le 0.17-0.24%, malosi tensile o 410Mpa, fua o le 230-250Mpa.O la matou gaosiga autu o le sila, e mafai ona matou tuʻuina atu le 20G Seamless paipa ma le maualuga ma le tau faʻatauvaʻa.Lenei e fa'ailoa atu ia te oe le matou 20G paipa fa'a'au'au fa'avae vaila'au ma mea fa'ainisinia.
O mea uma matou te faia o lo'o fa'aaofia i taimi uma i la matou fa'aupuga " Fa'atau muamua, Fa'alagolago muamua, tu'uina atu i totonu o le afifiina o mea'ai ma le puipuiga o le si'osi'omaga mo le ASTM A106 A53 Gr.B A179 20G Seamless Carbon Steel Pipe Cold Drawn Seamless Steel Pipe, Matou te faʻafeiloaʻi ma le faʻamaoni tagata faʻatau mai fafo e faʻatatau i lau felagolagomaʻi umi ma le atinaʻeina foi.
Pau lava le mea matou te faia o loʻo aʻafia ai i taimi uma i la matou faʻaupuga " Faʻatau muamua, Faʻalagolago muamua, tuuto i totonu o le afifiina o meaʻai ma le puipuiga o le siosiomaga moSaina 20G Seamless Steel Paipa, O loʻo i ai a matou faʻatauga faʻapitoa ma faʻamalosi, ma le tele o lala, faʻafeiloaʻi a matou tagata faʻatau.O lo'o matou su'eina ni faiga fa'apa'aga fa'apisinisi mo se taimi umi, ma fa'amautinoa o le a fa'amanuiaina e le au fa'atau oloa i le taimi pu'upu'u ma le umi.
