Abstract

A pipe section, especially an elbow pipe section, is cast to have an internal heat insulation lining so that the pipe section can withstand temperatures up to about 2500.degree. C. The internal heat insulation is first formed as a hollow casting core of carbon fiber composite material which, after curing, is inserted into a casting mold to function as the casting core which then becomes the internal heat insulation of the pipe section as the result of the casting of the pipe section, whereby the carbon fiber composite material is bonded to the interior surface of the pipe section.
