ASTM A519 4140 Paipa Fa'ama'a'a mo le Silini Hydraulic
Fa'atomuaga o le Oloa
Auaunaga fa'apitoa
O le JINYO o se fale gaosi oloa fa'aonaponei ma matou te fa'aaogaina tekinolosi gaosiga fa'aonaponei ma faiga fa'atonutonu lelei e fa'amautinoa ai o paipa ta'itasi ua fa'ama'aina e ausia a matou tulaga fa'atonuina lelei. Mai le filifiliga o meafaitino e o'o atu i le asiasiga mulimuli, matou te tautino atu e tu'uina atu paipa ua fa'ama'aina e sili atu i mea e fa'amoemoeina e a matou tagata fa'atau.
O lo'o iai i le JINYO se atina'e atoatoa ma se 'au fa'apitoa, ma e le gata i le tu'uina atu o paipa fa'amama lapopo'a masani, e mafai fo'i ona fa'apitoa paipa fa'ama'a'a. O a matou tautua fa'apitoa e aofia ai vaega uma mai le mamanu, gaosiga e o'o atu i le fa'agasologaina o mea, ma e mafai ona matou tu'uina atu ni fofo fa'apitoa e tusa ai ma mana'oga patino o tagata fa'atau. I se aotelega, o a matou paipa ua fa'ama'aina e fetaui lelei mo fa'aoga o le hydraulic cylinder ma ua matou tuuto atu e tu'uina atu i tagata fa'atau vaega autu e maualuga le sa'o ma le fa'atuatuaina o faiga hydraulic.
