A technique for installing and replacing, if necessary, readily bendable electrical heat-tracing cable on and insulating a network of installed pipes including straight sections, straight joints, and elbow sections is disclosed herein. In accordance with this technique, initially provided heat-tracing cable is installed in individual continuous sections along the length of and adjacent to the straight pipe sections, joints and elbow sections. Routing guides are placed over and/or under lengthwise surfaces of at least those segments of the heat-tracing cable adjacent to the joints and elbows and retained in place along with the cable itself. With the cable and routing guides so retained, a layer of thermal insulation is placed over the network of pipes as well as the cable and routing guides so that opposite ends of individual cable sections are readily accessible for connection with the source of electrical power or a section of replacement cable.
A method of installing readily bendable electrical heat-tracing cable on and insulating a network of already installed pipes including straight sections of pipes, straight joints, and elbow sections, said method comprising the steps of:
A heating and insulating arrangement for a network of previously installed pipes including straight sections of pipes, straight joints and elbow sections, said arrangement comprising:
In a heating and insulating arrangement for a network of installed pipes including straight pipe sections, segments or electrical heat-tracing cable directly adjacent to said pipe sections, channel assemblies positioned over but not under the lengthwise surfaces of said cable segments, and thermal insulation over said pipe sections, heat-tracing cable segments and channel members, the improvement comprising means forming part of said channel assemblies for pressing the adjacent cable segments directly against their respective pipe sections, said channel assemblies including channel members and wherein said pressing means including resilient spring members between a surface of said channel member and the outer lengthwise surfaces of the cable segments under said members.
A method of installing and replacing readily bendable electrical heat-tracing cable on and insulating a network of already installed pipes including straight sections of pipes, straight joints, and elbow sections, said method comprising the steps of:
In a heating and insulating arrangement for a network of installed pipes including straight pipe sections, segments of electrical heat-tracing cable directly adjacent to said pipe sections, channel assemblies positioned over but not under the lengthwise surfaces of said cable segments, and thermal insulation over said pipe sections, heat-tracing cable segments and channel members, the improvement comprising means forming part of said channel assemblies for pressing the adjacent cable segments directly against their respective pipe sections, said channel assemblies including channel members which are generally U-shaped and said pressing means including resilient material within said channel members above the outer lengthwise surface of the cable segments under said members.
In a heating and insulation arrangement for a network of installed pipes including straight pipe sections, segments of electrical heat-tracing cable directly adjacent to said pipe sections, channel assemblies positioned over but not under said lengthwise surfaces of said cable segments, and thermal insulation over said pipe sections, heat-tracing cable segments and channel members, the improvement comprising means forming part of said channel assemblies for pressing the adjacent cable segments directly against their respective pipe sections, said assemblies including channel members, each having an integrally formed lengthwise section thereof in engagement with an adjacent cable segment and serving as said pressing means.
In a heating and insulating arrangement for a network of installed pipes including straight pipe sections, segments of electrical heat-tracing cable adjacent to said pipe sections, guide assemblies positioned at least over the lengthwise surfaces of said cable segments, the improvement comprising means forming part of said guide assemblies for directly engaging the adjacent cable segments and pressing the engaged segments in the direction of their respective pipe sections, said guide assemblies being configured to have closed cross sections such that a section of each guide assembly is disposed between an adjacent cable segment and pipe section and such that the adjacent cable segment is pressed against the adjacent section of the associates guide assembly.
A method of installing a readily bendable electrical heat-tracing cable on and insulating a network of already installed pipes including straight sections of pipes, straight joints, and elbow sections, said method comprising the steps of:
A heating and insulating arrangement for a network of pipes including straight sections of pipes, straight joints, and elbows, said arrangement comprising:
