ABSTRACT:
An expansion joint having a working element of polytetrafluoroethylene is protected from fire by jacketing with an enclosure of refractory material. The jacket has openings through which pipe passes to and from the joint. A gland is inserted within the openings around the pipe for closing most of the gap therebetween while affording sufficient freedom of movement not to interfere with motion of the joint. Each gland is formed from a metal ring, channel shaped, coated on all surfaces with an intumescent material which expands in a fire to seal all remaining gaps between the pipe and the encircling opening in the jacket whereby hot gases are barred from passage. Alternatively, where radial movement is not required, the intumescent material may be coated directly on the refractory material around the opening surrounding the pipe. The principles of the gland and the use of the intumescent material may be applied wherever a fire stop and a thermal barrier are required in the space between two relatively movable non-combustible elements.
