ABSTRACT:
A method of forming a heat resistant gas transfer line. The line includes a metal outer shell, a tubular inner liner formed of a plurality of prefired refractory rings joined together by shiplap joints having expansion gaps, and an intermediate liner including bubble alumina concrete filling the annular space between the inner liner and the outer shell. The method includes placing on the inside lower surface of the outershell a plurality of bubble alumina concrete forms capable of supporting the refractory rings in the desired location within the outer shell, securing decomposable rings to the refractory rings in the area where the shiplap joints are to be so that a suitable expansion gap will be provided in the shiplap joints when the combustible rings are destroyed, assembling the refractory rings having the decomposable rings secured thereon on the concrete forms to form the tubular inner liner, filling in the annular area ebtween the inner liner and the outer shell with bubble alumina castable, curing the castable to form bubble alumina concrete, and destroying the decomposable ring by combustion.
