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.
ASTM A333 Grade 6 specification covers seamless and welded steel pipe for low temperature service. ASTM A333 Grade 6 Seamless Pipe 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.
