The invention discloses a pierce preventing pup joint for a choke manifold, which is applied to the technical field of drilling and is characterized in that a lining alloy bushing is embedded in a central hole in the inlet end of a pup joint shell; a connecting flange at the outlet end of the pup joint shell is connected with a flange plate through shell connection by using a stud, an alloy head is fixed at the inner side of a central hole of the flange plate, and the outlet end of the alloy head is fixed in the central hole of the flange plate; and the outlet end of the alloy head is provided with a central hole, the other end of the alloy head is hemispherical, and the outer wall of the alloy head is provided with an axial through hole communicated with the central hole. The pierce preventing pup joint has the effects of improving the erosion resistance of the choke manifold, reducing the erosion and piercing probabilities of the choke manifold and avoiding inducing well control safety accidents such as natural gas leakage and the like and has important functions for ensuring the success of well control work and realizing the well control safety.
