(57) Abstract Topic Freezing the poly butene tube at the cold area in winter seasonPrevention and 10,001, the poly butene tube the field where it breaks with freezingIt regards the insulative tube which can make conjunction and exchange repair simple. Solutions With the polyethylene resin material and the like the wholeInside the sheath tube 33 which possesses the flexibiility which provides the irregularity section of bellows conditionIn the section, with the synthetic resin material and the especially poly butene resin material formationThe flowing water tube 31 which it does outside the Interpolation sequence and aforementioned sheath tube 33, flowIn order to prevent freezing the siphon self control die heater belt 37The heater tube 38 which was formed the Interpolation with the synthetic resin material which it passesTo be located, in the peripheral face of the said heater tube and the aforementioned sheath tube,The adiabatic tube 3 which was formed with foaming resin material such as polyurethaneCanning 9, it is formed.
