Abstract: A conduit, specifically a hot-blast main for a blast furnace, is supported on a vessel specifically a hot-blast stove, into which it is connected by a branch, by means of at least one vertical support member and a framework mounted on the vessel and carrying the support member. The framework includes a strut or tie element extending from the end of the support member to the point of connection of the conduit branch into the furnace. The support member, which may be a rod hinged to the framework, may suspend the conduit from above or support it from below. This construction is simple and provides support for the conduit without problems due to vertical movement caused by thermal expansion of the point of connection into the vessel.
