Length: 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 |
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

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.
