ASTM A333 Grade 6, Seamless Steel Pipe for Low-Temperature Service
|
|
| |
ASTM A333 Standard covers seamless and welded steel pipe for low temperature service. The Grade 6 steel involved is similar to AISI 4032 low alloy steel. ASTM A333 Grade 6 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
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.
