ASTM A335 Alloy Alloy Pipe e se nang seamless

Tlhaloso e Khutšoanyane:

ASTM A335 hangata e bitsoa chrome moly pipe ka lebaka la lik'hemik'hale tse nang le Molybdenum (Mo) le Chromium (Cr).Molybdenum e eketsa matla a tšepe 'me Chromium (kapa chrome) ke karolo ea bohlokoa ea tšepe e sa hloekang.Pipe ea tšepe ea chrome moly alloy e etsa hore e be e loketseng ho sebelisoa lifemeng tsa motlakase, lihloekisi, lifeme tsa lik'hemik'hale tsa peterole, le lits'ebeletso tsa masimo a oli moo maro le likhase li tsamaisoang ka mocheso o phahameng haholo le likhatello.
