High temperature resistant tubes are described, which are useful as heat insulators for thermocouples. The tubes are made of spirally wound, refractory cements reinforced with non-woven webs of ceramic fibers. The tubes are advantageous in that by the method of their manufacture, they are free of significant proportions of organic binders and adhesives which may be volatilized at high temperatures, releasing gases.
