Abstract

Fire protection of pipe joints and valves in a pipeline is provided by two socket halves situated tightly against each other and against the pipe line and surrounding the joint, valve, or such. The socket halves are made from perforated stainless steel plate and have a fire insulation of heat expanding epoxy material on the inside, outside, or on both sides. One of the edges of the socket halves situated against each other comprises an internal cover plate with fire insulation which covers the joint between the two halves and prevents penetration of hot gases into the internal of the socket halves.
