Outer Pipe Shell
**************************************************************************
NOTE: For the outer shell, carbon steel is most
common; stainless steel will considerably limit
suppliers. Flanged joining, Class 150 or 300, is

vapors to permeate and become trapped between the
liner and the shell. Therefore, venting via weep
holes in the outer shell or venting flange collars
(note that a single manufacturer has a patent on
venting collars) are required to avoid gas
accumulation. These are not required for
nonpermeable liners such as PVDC. The use of
thermoplastics with aggressive chemicals may result
in a lower maximum operating temperature than that
rated for an unlined pipe composed of the same
material.

NICKEL AND NICKEL ALLOYS PIPING SYSTEMS
**************************************************************************
NOTE: The preferred method for joining nickel and
nickel alloy pipe is welding due to cost of
flanges. In all cases, only Schedules 40S and 80S
can be threaded due to wall thickness. Flanges
should be used when attaching nickel pipe to pumps,
process vessels, and other equipment that requires
removal periodically. Generally, for temperatures
up to 115 degrees C 240 degrees F, and normal
pressures encountered, the chloroprene gasket
specified is appropriate for most "dilute" process
liquids, water and sludge services. However, other
liquids may require other, more suitable gasket
materials.
