A53 pipes convey fluids at low/medium pressures and are also used for mechanical applications. An A53 pipe can be welded, flanged and shaped as necessary, is available in three main types (“F”, i.e. continuos welding/longitudinal furnace butt welded not suited for flanging, “S” seamless hot rolled and cold finished, and “E” ERW).
ASTM A53/ASME SA 53 carbon pipes are available in the size range 1/4 to 30 inches and schedules 10 to 160, both in seamless and welded execution, black and hot-dip galvanized (HDG).
TOLERANCES
1, The tolerances for ASTM A53 – ASME SA53 pipes are:
2, Wall thickness: the thickness of the pipe (“WT”) shall be, at any point, not less than the nominal pipe size minus 12.5% (a wt of NPS -13% would not be, for instance, acceptable) weight per foot: + / – 10%
PIPE END TYPES
1, Pipe schedule below 0.500 inches and schedule STD / XS pipes: plain or beveled ends
2, Pipe schedule above 0.500 inches and schedule XXS: Squared cut plain ends. If pipes are supplied with threaded ends, protection for threads is mandatory for pipes above 4 inches.
