FIRE-PROTECTING PIPE CONNECTOR, FIRE-PROTECTING PIPE CONNECTION, AND PIPE SYSTEM

摘要

Disclosed is a fire-protecting pipe connector for pipes made especially of fire-resistant material. Said fire-protecting pipe connector comprises a connection piece (30) made of an elastic material that can be connected to the first end piece in a tightly sealing manner, a connection piece (32) made of an elastic material, an intermediate piece (60) which is sealingly connected to the first and the second connection piece therebetween and is made of a material that is resistant to a medium conducted by the pipes when the material is not affected by heat generated by a fire while being non-rigid under the effect of heat generated by a fire, a support (84) which is made of a material that expands under the effect of heat generated by a fire and forms a fire-resistant, rigid member, and a support collar (120) made of a heat-conducting fire-resistant material.
