3.2 Construction. The cylinders shall be true of form and shall be stable when in an
upright position. The footrings shall be attached by welding and shall have a minimum of two
ventilation holes and two drainage holes equally spaced around the base of the cylinder and shall
be of the same outside diameter as that of the cylinder wall.
3.3 Cylinder processing.
3.3.1 Internal surfaces. The internal surfaces of drawn cylinders, prior to necking, shall
be free of mill scale, burrs, oxidation products, and all foreign matter. When required, only iron-
based abrasives shall be used to remove unstable surfaces or oxidation products from the
cylinder wall. Metal discoloration, rust bloom, and fixed scale shall not be considered criteria
for cylinder rejection.
3.3.2 Cylinder cleaning. After necking, drilling, threading and deburring, the cylinders
shall be cleared of loose particles by vacuum or by inverting the cylinder and using a compressed
air sweep (see 6.3). The cylinder shall be flushed with hot fluids when necessary to remove
grease, oil, and fat from processing. Chemicals that will react with anhydrous ammonia shall not
be used.
3.3.3 Cylinder drying. Internal cylinder moisture, from processing or hydrostatic testing,
shall be removed by inverting and steaming the surfaces until hot to the touch, followed by
drying with filtered air having a dew point of less that 30 °F (-1 °C). In lieu of filtered air, drying
by suction of ambient air through the cylinder is allowed. Closure shall be carried out
immediately to limit atmospheric interchange.
