Fa'aaliga:
O le tau o loʻo i luga e mo le 6M paipa uʻamea umi.
2.5-inisi i le 12-inisi 5.8-mita tumau umi e fa'atuputeleina i le 100 yuan i le tone, ae o isi e tumau e le suia.
E le gata i lea, o le umi e tatau ona fuafua eseese.
O le tau o loʻo i luga e aofia ai le vali uliuli, pulou palasitika i pito uma e lua, faʻapipiʻi faʻapipiʻi uʻamea hexagonal, tau iunite tau lafoga i Tianjin Port; ≤1-1/2″ pito mafolafola, ≥2″ pito fa'ailo (30-35°).
I le faaopoopo atu i tulaga o loʻo i luga, e mafai foi ona tatou gaosia paipa uʻamea e leai ni faʻataʻitaʻiga o tulaga eseese e tusa ai ma tulaga JIS Iapani, BS British standards, EN European standards ma manaoga o tagata faatau, ma o le tau e mafai ona faʻatalanoa. Faʻafeiloaʻi ma le faamaoni tagata fou ma tuai e galulue faʻatasi ma la matou kamupani!
