DE19504790C2 - Thermal insulation bracket system for vertical and horizontal high-temperature pipes - Google Patents

Description

The invention relates to a heat-insulating mounting system for vertical and horizontal high-temperature pipes, especially for pipe clamps, fixed and sliding bearings, etc. under Use of ceramic moldings.

For storage and fastening of pipes, also for High temperature pipelines are a variety of constructive Known solutions. According to the respective application will the safety and durability of such fasteners through the use of cast steel and mostly high-alloy Special steels guaranteed to the occurring temperatures and absorb mechanical loads.

Such fasteners are such. B. from DE-OS 34 21 326, DE-OS 38 17 015, DE-OS 38 17 059, DE-OS 40 39 260, DE-OS 41 23 390 and DE-OS 42 31 663 are sufficiently described. Everyone common solutions is that through the use of Cast steel or high-alloy steels when used High temperature pipelines add a significant cost the manufacture of such fasteners occurs and their service life is limited when using low-alloy steels are.

DE-PS 9 24 117 is a pipe clamp for suspensions, Plain bearings and fixed points for steam lines known between the load-bearing clamp and the pipe wall contains segmental mass, the spaces with Asbestos deposits are filled out. The rigidity of the chosen Enclosure in a U shape requires an uncontrolled Displacement of the insulating liner and a Load transfer via max. two points or lines with no predictable forces, so this clamp shape for High temperature piping is no longer used.

Furthermore, DE-OS 38 08 140 describes a multi-part Pipe clamp with assembled ring halves from one Thermal insulation, in the screwed metal bracket halves are foamed. Except for doubts about the Possible use of foamed thermal insulation material High temperature piping affects the required  exact fit of the required bypass groove disadvantageous for the Manufacturing process of the overall system.

The invention is therefore based on the object Equipment of such fasteners for vertical and horizontal high temperature piping with heat resistant Materials within the supporting system create a cost-effective when using normal structural steels Manufacturing and to achieve a long service life.

This task is done by defining the distinctive Features of the claims solved.

The advantage of the invention is that when using the bracket system according to the invention the use of unalloyed Materials with high load capacity, low weight and low cost is enabled. Furthermore allowed the always available accessibility of the supporting structure status monitoring and detection at all times Eliminate any damage so that operational safety is significantly increased.

Other advantages are that by not interrupted insulation a considerable loss of energy and the undesirable heating of the environment is avoided and through the chosen use of ceramic or Chamotte molded bodies an electrical separation between media-carrying pipelines, apparatus and containers and whose brackets or bearings are made without the particular Stray currents for short-term corrosion damage and Can lead to hole formation.

Further advantages and advantageous configurations of the invention can be found in the following exemplary embodiments.

The invention is based on two Exemplary embodiments are explained in more detail. In the associated Show drawings

Fig. 1 and 2, a support system for horizontal pipes,

FIGS. 3 and 4, a support system for vertical pipes.

On a vertically laid high-temperature pipeline, a separating layer made of trapezoidal insulating blocks 2 is assembled from a heat-resistant ceramic or chamotte at the support point of the part to be carried by means of an external carrier tape 3 . The shape and size of the trapezoidal insulating blocks 2 made of a pressure-resistant and heat-insulating ceramic can be selected so that, on the one hand, only compressive stresses occur and, on the other hand, all standard pipe dimensions can be detected with one size and the operating load of a ring 4 attached to the pipe on the separating layer 5 and the outer ring 6 is transferable.

For horizontal high-temperature pipelines, a covering or intermediate layer 1 made of a thin, heat-resistant metal is arranged at the point of support to protect the pipeline wall and for load distribution, onto which a separating layer 5 made of trapezoidal insulating blocks 2 made of semicircles is made of a heat-resistant ceramic or chamotte by means of an external carrier tape 3 mounted, so that on the one hand only compressive stresses occur and on the other hand all standard pipe dimensions can be recorded with one size.

The separation of supports for apparatus and Containers by means of such insulating blocks, with their Arrangement and design to the specific conditions are adaptable to the individual case.
