ATTACHED MEMORANDUM
1. INTRODUCTION. Pipes and tubings can be prepared into many varied shapes
and forms. The ability of the mechanic to prepare a pipe layout that will not leak
and is safe to use will prevent many valuable pieces of equipment from being
inoperable.
2.
STEEL PIPE AND FITTINGS.
a. General. Pipe is used to distribute hot and cold water, for steam and hot
water systems, gas and air piping systems, and vent installations. Most pipe in
use today is steel pipe. It is furnished plain (black) or galvanized (coated with
zinc), normally in 21-foot lengths, threaded or unthreaded, and in sizes (nominal
inside diameter) of 1/8 inch and larger. In most sizes it is available in three
weights or strengths: standard, extra strong, and double extra strong. Iron pipe
may rust making it undesirable for most military use.
