  • Method and apparatus for applying foam insulation to pipe
    Patent number: 4094715
    Abstract: A method of applying foamed insulation to pipe is contemplated by the present invention. The pipe is moved longitudinally while being rotated about its longitudinal axis. A sprayable, foamable liquid is directed onto the surface of the pipe from a stationary location and is allowed to partially rise before a protective outer jacket is wrapped around the rising foam. The wrapping step includes application of sufficient pressure to the foam to increase the final density thereof, at the outer surface, by from 10% to 25% above the density if the foam was allowed to rise uninhibited.
