ASTM A333 Grade 6 seamless pipes are applicated for low temperature service.
ASTM A333 Grade 6 Seamless Pipe involved is similar to AISI 4032 low alloy steel.
ASTM A333 Grade 6 is the part of standard covers wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. ASTM A333 Grade 6 alloy pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.
Seamless and Welded Steel Pipe size for Low-Temperature Service:
-
Outer Dimensions: 19.05mm – 114.3mm
-
Wall Thickness: 2.0mm – 14 mm
-
Length: max 16000mm
Application: Seamless and Welded Steel Pipe for Low-Temperature Service.
Steel grade: ASTM A333 Grade 6
Packing:
Bare packing/bundle packing/crate packing/wooden protection at the both sides of tubes and suitably protected for sea-worthly delivery or as requested.
Inspection and Test: Chemical Composition Inspection, Mechanical Properties Test(Tensile Strength,Yield Strength, Elongation, Flaring, Flattening, Bending, Hardness, Impact Test), Surface and Dimension Test,No-destructive Test, Hydrostatic Test.
Surface treatment: Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting.
Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.
