RE: Lowering an existing pipe.
shut off valves
remove the old
install the new and turn valves back on
make sure the new design works
not sure this is adequate material for an entire book, what is your specific question? what kind of line? what kind of service?
RE: Lowering an existing pipe.
design new line
design temporary line
get regulatory approval for temporary line (as it may not meet all design codes and conditions)
install temporary line
test temporary line
switch to temporary line
remove the old line
install new permanent line
test new system
diconnect temporary system
retest new system in final configuration
remove temporary system
