ASTM A355 P22 Steel Pipe Mechanical Tests Specified



A335 is often called chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel as well as the elastic limit, resistance to wear, impact qualities, and hardenability.

The range of ASTM A335 P22 pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practice.

The different mechanical test requirements for pipes, namely, transverse or longitudinal tension test, flattening test, and hardness or bend test are presented.Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.
Surface treatment of ASTM A355 P22 Steel Pipe :
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.
Sizes of  P22 Steel Pipe 
NPS 1/4'' to NPS 48'' 
Wall Thickness - Schedules 40 through 160, STD, XS, XXS. 
Unscheduled heavy wall pipe thicknesses available up to 4 inches.
