Thermally insulating half-pipe system for pipe reveals, apparatus and containers with hot media

The invention relates to a heat-insulating support system for vertical and horizontal high-temperature pipelines, in particular for pipe clamps, fixed and sliding bearings, etc. as well as apparatus and containers with hot media using ceramic molded bodies,

A variety of structural solutions are known for the storage and fastening of pipelines, including high-temperature pipelines. Depending on the specific application, the safety and durability of such fastenings is ensured by the use of cast steel and mostly high-alloy special steels in order to absorb the temperatures and mechanical loads that occur.

Such fastening devices are adequately described, for example, in DE-OS 34 21 326, DE-OS 38 17 015, DE-OS 38 17 059, DE-OS 40 39260, DE-OS 41 23 390 and DE-OS 42 31 663. What all known solutions have in common is that the use of cast steel or high-alloy steels when used on high-temperature pipelines results in considerable costs in the manufacture of such fastening devices and their service life is limited when low-alloy steels are used.

The invention is therefore based on the object of creating the possibility of achieving cost-effective production and a long service life when using normal structural steels by equipping such fastening means for high-temperature pipelines and containers with heat-resistant materials.

This problem is solved by defining the characterising features of the main claim.

Further embodiments of the invention are characterized in the subclaims.

The advantage of the invention is that when using the holding system according to the invention, the use of unalloyed materials with high load-bearing capacity, low dead weight and

low cost. Furthermore, the constant accessibility of the supporting structure allows for a status check at any time as well as the detection and removal of any damage, so that operational safety is significantly increased.

Further advantages are that the uninterrupted thermal insulation prevents considerable energy loss and the undesirable heating of the environment, and the selected use of ceramic or fireclay molded bodies creates an electrical separation between media-carrying pipes, devices and containers and their supports or bearings, without which stray currents in particular can lead to short-term corrosion damage and the formation of holes.

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

Example

The invention will be explained in more detail below using two exemplary embodiments. The accompanying drawings show

Fig. 1 and 2 a support system for horizontal pipelines Fig. 3 and 4 a support system for vertical pipelines.

At the support point of the part to be supported, a covering or intermediate layer 1 made of a thin heat-resistant metal is arranged to protect the pipe wall and to distribute the load, onto which a separating layer made of trapezoidal insulating blocks 2 made of a heat-resistant ceramic or fireclay, arranged in semicircular rings, is mounted by means of an external support band 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 that are easy to control occur and, on the other hand, all standardized pipe dimensions are covered by one size.

The same insulating blocks 2 can be used for vertical pipelines, which are then loaded on the end faces. The operating load is transferred from the ring 4 attached to the pipe to the separating layer 5 and the outer ring 6.

Similarly, the separation of supports for apparatus and containers is carried out using such insulating blocks, whereby their arrangement and shape can be adapted to the specific conditions of the individual case.

All features presented in the description, the following claims and the drawings can be significant both individually and in any combination with one another.
