The utility model relates to a centralizer and particularly relates to a heat insulation pipe centralizer. Fixing grooves are formed in the outer wall of a tubular main body of the centralizer, a centralizing ring is mounted in the fixing groove and is made of a nylon material, a positioning ring screw thread is connected to the outer wall of the tubular main body and fixes the centralizing ring, and the tubular main body is sleeved in from a pipe-collar-free end of a heat insulation pipe and is clamped in a pipe collar at the tail end of the heat insulation pipe. The heat insulation pipe centralizer achieves convenience in mounting and good effects of heat insulation and centralization, and is not broken easily or does not fall off easily. The defects that an existing heat insulation pipe centralizer is broken easily, falls off easily and is not ideal in the effects of heat insulation and centralization are overcome.
