The invention discloses an anti-freezing gas water heater furnace pipe comprising a furnace pipe body and high-density corrugated pipes, the high-density corrugated pipes are arranged at the corners of copper pipes outside the furnace pipe body, and the high-density corrugated pipes are connected with the copper pipes outside the furnace pipe body in a welded mode. The copper bent pipe at the external corner of an existing water heater furnace pipe is changed into the high-density corrugated pipe, the expansion coefficient of the high-density corrugated pipe is larger than the expansion coefficient of conversion from a water state to an ice state, the problem of frost cracking of the furnace pipe can be effectively solved, and the service life of the furnace pipe is greatly prolonged; the structure improvement is simple, the cost is low, and popularization is convenient. 本发明公开了防冻燃气热水器炉胆。包括炉胆主体和高密度波纹管，所述炉胆主体外部铜管的拐弯处为高密度波纹管，所述高密度波纹管与炉胆主体外部铜管为焊接连接。本发明将现有热水器炉胆外部拐弯处的铜弯管改为高密度波纹管，高密度波纹管的可膨胀系数大于水到冰状态转变的膨胀系数，能够有效解决冻裂炉
