Chrome Moly pipe has become a standard in the power generation industry and the petro-chemical industry, not only because of its tensile strength, corrosion resistance and high-temperature strength, but also for its cost-effectiveness. Grades P-11, P-22 - P-91 & P-92 are prevalent grades for the power industry, while P-5 & P-9 are the major refinery processing grades utilized.

· Testing Requirements for seamless A106 Carbon Steel Pipe
o Hydrostatic Testing: Inspection test pressures produce a stress in the pipe wall equal to 60% of specified minimum yield strength (SMYS) at room temperature. Maximum pressures are not to exceed 2,500 psi for NPS 3 and under, and 2,800 psi for the larger sizes. Pressure is maintained for no less than 5 seconds.
o Mechanical Tests:
§ Tensile Test: Either transverse or longitudinal are acceptable for NPS 8 and larger
§ Tensile tests smaller than NPS 8: Longitudinal testing only
§ Flattening Test: NPS 2 and larger
§ Bending Test (cold): NPS 2 and under

6 and larger
200 or less
o Number of Tests: One tensile test per 200 lengths.
· Permissible Variations in Dimension
o Wall thickness: The minimum wall thickness at any point shall not be more than 12.5% under the nominal wall thickness specified.
o Weights per foot: The weight of any individual length shall not vary more than 10% over and 3.5% under that specified. NOTE – NPS 4 and smaller are weighed in lots. Larger sizes are weighted by individualo Outside diameter: Shall not vary from standard specified below at any point.
· Lengths of A106 seamless carbon steel pipe
Lengths of Bangdong Pipeline Tubular Products A106 seamless carbon steel pipe must be specified on order. No [joiners" are permitted unless otherwise specified. If no definite lengths are required, the following practice applies:
o Single random – 16` – 22` (5% may be 12` – 16`)
o Double random – Minimum length is 22`. Minimum average is 35` (5% may be between 16` – 22`)
· Marking Requirements
Rolled, die stamped, or paint stenciled (manufacturer`s option).
o Manufacturer`s name, brand, or trademark
o A106 A, A106 B, or A106 C
o Hydro-static test pressure and/or NDE, or NH if neither is specified
o Size, length, weight per foot (NPS 4 and larger)
o ANSI schedule number or weight class or wall thickness
o Additional [S" if tested supplementary requirements
