Abstract
An insulated pipe is disclosed comprising a fiber felt batt or first layer secured to the pipe inner surface with studs protruding therethrough this first layer, a high temperature resistant metal shield mounted on the studs and contiguous to the first layer, and a metal grating reinforced erosion resistant castable refractory mounted over all and attached to the tops of the studs for providing an efficient, high temperature and shock resistant, internally insulated pipe.
Claims14
A high temperature and shock resistant insulated pipe for transporting high velocity gas or fluidized solids comprising,
- a. a pipe having an inner surface,
- b. a batt of fiber felt secured to said pipe inner surface,
- c. a high temperature resistant metal shield mounted contiguous with the inner surface of said fiber felt batt and secured to the pipe inner surface, and
- d. an erosion resistant and metal reinforced castable refractory mounted contiguous with the inner surface of said high temperature resistant metal shield and secured to the pipe inner surface for providing a high temperature resistant and high mechanical strength insulated pipe.
A high temperature and mechanical strength insulated pipe comprising,
- a. pipe means having an inner surface,
- b. fiber felt batt means for said pipe means inner surface,
- c. high temperature resistant metal shield means contiguous with the inner surface of said fiber felt batt means, and
- d. erosion resistant castable refractory means contiguous with the inner surface of said high temperature resistant metal shield means for providing a high temperature resistant and high mechanical strength insulated pipe.
