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.

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.

Heat Treatment
Product is supplied in the normalized, 1500 f and air cooled, condition. It may be quenched and tempered by heating to 1475 F, quench in circulating water and then temper by re-heating to 1100 F and rapid air cooling.

Forging
Product is supplied in pipe form and not normally forged from that shape.

Hot Working
Hot working may be done qt 2000 F down to 1600 F if need be. Do not hot work below 1550 F and immediately following hot working cool in a controlled atmosphere furnace from a temperature above 1550 F.

Cold Working
Cold working may be done by conventional methods.

Annealing
Anneal, or normalize, at 1600 F and air cool.
