Abstract:
A thermal insulation system for cladding a fluid-cooled pipe comprising:a. a plurality of studs welded directly to an exterior surface of a length of pipe to be insulated;b. a plurality of preformed insulative refractory members adapted to cover a majority of a circumference of the pipe, each refractory member having an elongated aperture completely therethrough through which one of said studs may be received;c. a plurality of removable fasteners engaging said studs so that said apertured refractory members are secured to said length of pipe and so that said apertured refractory members may slide parallel to a longitudinal axis of the pipe when said removable fasteners are loosened from said studs disposed through the apertures; andd. a plurality of refractory members which interlock with one another and which do not have apertures therethrough secured between the apertured refractory members thereby to cover a majority of the pipe surface, each of said interlocking refractory members without an aperture featuring an ""H"" shape so as to engage and disengage neighboring refractory members above and below by sliding parallel to the longitudinal axis of the pipe so that said refractory members without apertures may be removed without removing any fasteners from said studs.
