Duplex paipa u'amea u'amea ua amata ona sili atu ma sili atu ona taatele. Ona o lona tetee sili atu i le chloride stress corrosion ta'e, maualuga le vevela conductivity, ma le maualalo coefficient o le faalauteleina vevela, duplex tubing uʻamea uamea o loʻo ofoina atu e le tele uʻamea uʻamea uʻamea.
Wuxi Cepheus o se tasi o taʻutaʻua gaosi oloa ma faʻatau oloa uʻamea. Duplex paipa stainless o se tasi o oloa tele i Wuxi Cepheus.
Duplex paipa uamea e mafai ona vaevaeina i ni ituaiga se lua: seamless ma uelo paipa uamea. Wuxi Cepheus e mafai ona gaosia paipa duplex uamea stainless i S31500, S31803, S32205, S32304, S32520, S32550, S32750, S32760, ma isi.
Duplex paipa uamea e masani ona su'esu'eina i le lautele 10mm i le 762mm. O le mafiafia o le puipui o le duplex stainless tube matou te gaosia o le 0.5-50mm.
