Grade P92 P91 Hot Rolled Structural Steel Pipe / Tubing Heavy Wall
Thickness
TIPTOP is providing ASTM A335 P92 alloy steel seamless pipes, which
are mainly used for high-temperature service. P92 pipe a kind of
chrome moly pipes listed in ASTM A335, a standard in power
generation and petrochemical industry. TIPTOP supply a full range
of A335 chrome moly pipes.
Designated as UNS K92460, ASTM A335 P92 is also known as 9Cr-2W
alloy steel. Its equivalent includes ASTM A213 T92, ASME SA335 P92,
ASME SA213 T92, as well as EN standard X10CrWMoVNb9-2. The Grade
P92 are generally furnished as seamless pipes, tubes, or fittings.
