Heat Treatment Requirements:

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

Normalizing per ASTM A333 Standard Specification for Seamless and Welded Steel Pipe 

 

Quenched and Tempered per A 333/A 333M - 05

 

Testing:

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.

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

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

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.

Hydrostatic Test

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.
