Pipe Units: Pipe units include rigging, erecting and aligning of pipe. It is customary to

the case add 20 percent to handling pipe units for elimination of field make-ons and
handling of additional weight.
Cut and Thread Units: Cut and thread units include hand cutting and threading of pipe
two inches and smaller and machine cutting and threading of sizes two and one half
inches and larger.
Make-On Units: Make-on units include making on of screwed type fittings. Ells = two
make-ons, tees = three make-ons, etc.
Butt Welds: Butt welds including lead burning units include circumferntial manual elec-
tric weld and fusing together of lead at joint.
Bolt-Up Units: Bolt-up units include bolting together of flanged connections.
