ASTM A333 Grade 1 Seamless Pipe

Date:2018-07-31    View:986      Tag:ASTM A333 Grade 1 Seamless Pipe
ASMT A333 1 seamless and welded pipes should be treated to control their microstructure. Tensile test, impact test, hydrostatic test and non-destructive electrical test shall be carried out according to the prescribed requirements. ASTM A333 1 is part of the standard covering wall seamless and welded carbon and alloy steel tubes, designed for low temperature use. ASTM A333 1 grade alloy pipe should be manufactured by seamless or welding process without filler metal in welding operation. Seamless and welded steel tubes 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 1

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.
