ASTM A333 Grade 6 Seamless Pipe
ASTM A333 Grade 6 Seamless Pipe
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.
This specification covers seamless and welded steel pipe for low temperature service. The Grade 6 alloy steel involved is similar to AISI 4032 low alloy steel. 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.
