Matou te taumafai mo le tulaga lelei, lagolago i tagata faʻatau ", faʻamoemoe e avea ma 'au galulue faʻatasi ma faʻatautaia pisinisi mo le aufaigaluega, faʻatau oloa ma tagata faʻatau, iloa le taua o faʻasoa ma faʻaauau pea le maketiina mo le Carbon Steel Seamless Tube/Pipe, E le gata i lea, o le matou kamupani e pipii i tulaga maualuga ma tau taugofie, ma matou tuʻuina atu foʻi kamupani OEM sili i le tele o taʻutaʻua taʻutaʻua faʻatauvaʻa maketi i le lalolagi atoa, ua matou faʻalauiloaina le taʻiala o le fausiaina o ituaiga ma faʻafouina le agaga o le "auʻaunaga faʻaletagata ma le faʻamaoni", faʻatasi ai ma se faʻamoemoe e maua le faʻalauiloaina o le lalolagi. ma atinae gafataulimaina.
ASTM A106 GR. B paipa u'amea seamless e lelei le faatinoga o le uelo. Ona o le maualalo o le C anotusi, e masani lava e leai se fausaga faʻamaʻa ogaoga ona o le uelo, ma o le sooga faʻapipiʻi e lelei le palasitika ma le faigata. O le fa'agasologa uma o le uelo e mafai ona maua fa'amalieina so'o fa'atasi e aunoa ma ni faiga fa'atekonolosi fa'apitoa.
ASTM A106 GR. B ma le 20 # e tutusa i le tuufaatasiga o vailaʻau ma mea faʻainisinia ma e masani ona suitulaga le tasi i le isi, ae o loʻo iai eseesega, aemaise lava i le faʻaaogaina o manaʻoga faʻalautele. o GB8163 20 # uamea paipa e -19 ℃, ao ASMR B31.3 stipulates o le vevela talafeagai aupito maualalo o A106 GR. B uamea paipa e -29 ℃, ma o loʻo i ai le tulaga o le leai o se aʻafiaga o suʻega. E ui lava o loʻo i ai eseesega i le faʻatulagaina o mamanu, o le mafuaaga loloto o le eseesega i le tulaga pulea o le Mn content. , ae o le tagata faʻatau e tatau ona nofouta i nei eseesega ma logoina le gaosiga o manaʻoga i le taimi o le faʻatau, a le o lea e ono tulaʻi mai faʻafitauli i lalo ole manaʻoga sili atu.
