Refinery Seamless Carbon Steel Pipe A333 Grade 3 Pressure Vessel
Application
ASTM A333 Grade 3 is the part of standard covers wall seamless and
welded carbon and alloy steel pipe intended for use at low
temperatures. ASTM A333 Grade 3 alloy pipe shall be made by the
seamless or welding process with the addition of no filler metal in
the welding operation.
