Abstract

A sampling tube bundle includes a tube bundle body and a joint assembly. The tube bundle body includes a gas sampling tube for transmitting sampling gas; a metal woven layer wrapping an outer circumference of the gas sampling tube; a heating pad comprising a heat tracing cable wrapping an outer circumference of the metal woven layer, for heating the sampling gas in the gas sampling tube; a flame resistant tape wound around an outer circumference of the of the heating pad; a plurality of signal transmission lines circumferentially spaced apart from one another are arranged outside the flame resistant tape; and a sheath located outside the signal transmission line. The joint assembly is arranged on an end of the tube bundle body, for connecting to an analysis device or a sampling device.
