ASTM A199M-89 

Seamless Cold Drawn Intermediate Alloy Steel Heat Exchanger and Condenser Tubes

This standard is issued snder the fixed designatioa A 199/A 199M ; the number immediately following the designation indicates the year of original adpton or , in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This specification covedrs several grades of minimum-wall-thickness, chromium-molybdenum and chromium-molybdenum-silicon, seamless, cold-drawn, intermediate alloy steel tubes for heat exchangers, condensers, and similar heat transfer apparatus.

1.2 The tubing sizes usually furnished to this specification are 1/8 to 3 in. [3.2 to 76.2 mm) in outside diameter. Tubing having other dimensions may be furnished provided such tubes comply with all other requirements of this spedification.

1.3 Mechanical property requirements do not apply to tubing smaller than 1/8 in [3.2 mm] in inside diameter or 0.015 in [0.4mm] in thickness. 

1.4 The values stated in either inch-pound units or SO units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therfore, each system must ve used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.

Note-The above table gives the computed minimum eiongation values for each 1/32-in. [0.8 mm] decrease in wall thickness. Where the wall thickness lies between two vallues shown above. the minimum elongation value shall be detemined by the following equation: For all Grades except T91:E =48t + 15.00 [E = 1.87t + 15.00]
For Grade T91: E = 32t + 10.00

where:
E = elongation in 2 in.or 50 mm, %, and
t = actual thickness of spectimen, in.
B Calculated elongation requirements shall be rounded to the nearest whole number.
