Definition
  1. Noun:
    • A series of tubes (joined by screwed collars) that connect a drilling platform to the drilling bit; rotates the bit and supplies drilling mud: A "drilling pipe" is a long, connected assembly of tubular steel sections used in the process of drilling a well. Its primary functions are to transmit rotational force from the surface to the drill bit at the bottom of the hole and to serve as a conduit for circulating drilling fluid (mud) down to the bit and back up to the surface.

  • "drilling pipe failure": Refers to a mechanical breakdown, such as a twist-off or burst, in the pipe string.

Synonyms
