2.Wall Thickness:2.0mm-60mm

3.Lengths: Lengths required shall be specified on order.If no definite lengths required, following practice applies:

Single Random — 17′ ~ 24′ lengths

Double Random — 36′ ~ 44′ lengths

Heat Treatment Requirements: 

All seamless and welded pipe shall be treated to control their microstructure by the following methods:

1.Normalizing per ASTM A333 Standard Specification for Seamless and Welded Steel Pipe for Low Temperature Service section 4.2.1.1; section 4.2.1.2 or section 4.2.1.3

2.Quenched and Tempered per A 333/A 333M – 05 section 4.2.2.1

3.Double Normalized and Tempered per A 333/A 333M – 05 section 4.2.2.2

Delivery:

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.

1.For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot.

2.For small lots, at least one pipe shall be tested.

3.For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe.

4.Hydrostatic Test

5. Impact Test One notched bar impact test, consisting of breaking three specimens shall be made from each heat represtented in a heat-treatment load on specimens taken from the finished pipe.

 

Surface treatment: 

Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting.

Required Markings on Each Length (On Tags attached to each Bundle in case of Bundled Pipe):

Markings will adhere to prescribed specifications in A 999/A999M and be: Rolled, Stamped, or Stenciled (Mfrs. Option)
