Abstract
The invention relates to a fluororesin tube. More specifically, the invention provides a fluororesin tubular member that has low gas permeability. The fluororesin tubular member of the present invention uses a fluororesin as a starting material and is stretched in the axial direction and heat set once molding has been performed. Gas permeability may accordingly be reduced as compared to tubular bodies obtained merely by means of the molding of a fluororesin; therefore, if the tubular member is used as a material for chemical supply lines or other pipework that requires a fluororesin tube, it is possible to prevent gas from leaking and condensation from forming on the piping surface.
