n: also called kelly hose or rotary hose. See rotary hose.

n: see drilling hose.

n: a steel-reinforced, flexible hose that is installed between the standpipe and the swivel or top drive. It conducts drilling mud from the standpipe to the swivel or top drive. Also called the kelly hose or the mud hose.

the connection from the mud pump to the stand pipe. Also called the mud hose or kelly hose.

n: a vertical pipe rising along the side of the derrick or mast, which joins the discharge line leading from the mud pump to the rotary hose and through which mud is pumped into the hole.

n: A rigid metal conduit that provides the high-pressure pathway for drilling mud to travel approximately one-third of the way up the derrick, where it connects to a flexible high-pressure hose (kelly hose). Many large rigs are fitted with dual standpipes so

the pipe in the derrick that delivers mud to the kelly hose.
