ASTM A192 ASME SA192 Seamless Carbon Steel Boiler Tube For Heat
Exchanger
ASTM A192, identical with ASME SA-192, is the standard
specification covering minimum-wall-thickness seamless carbon steel
boiler and superheater tubes for high pressure service. The tubing
sizes and thicknesses usually furnished to ASTM A192 are 1/2″ to 7″
[12.7 mm to 177.8 mm] outside diameter and 0.085″ to 1.000″ [2.2 mm
to 25.4 mm], inclusive, in minimum wall thickness. Tubing having
other dimensions may be furnished, provided such tubes comply with
all other requirements of this specification.
Seamless cold-drawn tube for tubular heat exchangers, condensers,
and similar heat transfer apparatus.This pipe shall be made by the
cold drawn process
Application: For high, middle, low pressure boiler and pressure purpose
