Abstract

A leakproof and fireproof tubing according to the invention comprises an inner tube for guiding a chemical fluid, a heater surrounding the inner tube, a foil enclosing the inner tube which is already surrounded by the heater, and an outer tube surrounding and coaxial with the inner tube. When chemical fluid leakage or a fire caused by a short circuit in the heater is encountered, the tubing can efficiently prevent the chemical fluid leakage and fire from further extending to the outside atmosphere. In coordination with the use of a sensor, the failure of the tubing can be repaired in a timely manner.
