Abstract
A method for forming an insulated pipe resistant to high temperatures and great shock forces comprises basically, forming a batt of fiber felt to the inner surface of the pipe, securing a high temperature resistant metal shield over the inner surface of the fiber felt batt, and forming an erosion resistant castable refractory over the inner surface of the high temperature resistant metal shield.

A method for making a pipe high temperature and shock resistant for resisting vibrations due to passage therein of high velocity gas or fluidized solids at elevated temperatures comprising the steps of,
- a. forming a batt of fiber felt to the inner surface of a pipe,
- b. securing a high temperature resistant metal shield over the inner surface of the fiber felt batt in the pipe, and
- c. forming an erosion resistant castable refractory over the inner surface of the high temperature resistant metal shield for forming a high temperature resistant and high mechanical strength insulation in the pipe.
A method for forming a high temperature, shock resistant pipe comprising the steps of,
- a. fastening a batt of fiber felt to the inner surface of a pipe,
- b. positioning a shield of high temperature resistant metal over the inner surface of the batt of fiber felt, and
- c. fixedly securing an erosion resistant castable refractory in the pipe over the thin sheet of high temperature resistant metal for forming a high temperature, shock resistant pipe.
