When the pressure in the inner pressure of 210 is too large, the pipe member 2 〇 ruptures, and the damper device 218 can be a rupture piece. When the pressure is too large, the rupture piece can be unbearably and automatically cracked, thereby reducing the inside of the pipe member 21〇. pressure. The heating device 220 is used to continuously heat the pipe member 21〇 until the temperature of the official wall outside the pipe member 210 is maintained at a first operating temperature (about C)', since the internal volume of the official member 210 is constant, the inside of the tubular member 21 is The pressure will increase with the increase of the internal temperature. At the first operating temperature, the internal pressure of the official member 210 will be maintained at a first operating pressure (about 1200 psi), due to the temperature of the tube wall outside the tube 210. Slightly higher than the inner tube wall temperature _ degree 'and the internal pressure of the tube 210 will be higher than its external pressure (normal pressure is 14.7 psi), so the tube wall will be subjected to stress within the tube 210 to generate axial cracks.
