Abstract

The present invention relates to a bursting insert for installation in a pipeline system for transporting a fluid showing a spontaneous exothermic reaction. The bursting insert comprises a wall which surrounds—at least in part on the outside—a passage volume having the fluid flowing therethrough in a passage direction. A pressure discharge line which is sealed relative to the passage volume with a bursting body extends out of the passage volume. When a predetermined bursting pressure is exceeded, the bursting body can be transferred into a state in which the passage volume and the pressure discharge line are interconnected in fluid-conducting fashion. For an easy mounting of the bursting body, the bursting insert can be designed as a pipeline module which can be installed and dismounted repeatedly in the pipeline system for replacing the bursting body.

Claims (33)

1. A bursting insert for installation in a fluid transporting pipeline or apparatus comprising a wall which at least partially surrounds a passage volume through which fluid flows in a passage direction, the bursting insert comprising a pressure discharge line extending from the passage volume, and a bursting body which seals the pressure discharge line relative to the passage volume and which, when a predetermined bursting pressure is exceeded, is transferable to a state in which the passage volume and the pressure discharge line are interconnected in fluid-conducting relationship, wherein the bursting insert is configured as a pipeline module adapted for repeated installation and removal with respect to the pipeline or apparatus permitting replacement of the bursting body, and wherein the bursting body is mounted from an inside location of the wall.

2. The bursting insert according to claim 1 , wherein the pressure discharge line is defined at least in part as an opening in the wall.

3. The bursting insert according to claim 1 , wherein the bursting body is mounted in an area of the wall surrounding the pressure discharge line.

4. The bursting insert according to claim 1 , wherein the bursting body is larger than a flow cross-section of the pressure discharge line.

5. The bursting insert according to claim 1 , wherein the bursting body and the wall are located at substantially the same distance from a center of the passage volume.

6. The bursting insert according to claim 1 , wherein the bursting body forms part of the wall.

7. The bursting insert according to claim 1 , wherein the bursting body is detachably mounted on an inner surface of the wall.

8. The bursting insert according to claim 1 , wherein the bursting body is substantially disc shaped.

9. The bursting insert according to claim 8 , wherein the bursting body is curved in the passage direction.

10. The bursting insert according to claim 8 , wherein the bursting body has a cross-section generally shaped as a spherical cap.

11. The bursting insert according to claim 8 , wherein the bursting body curves into the pressure discharge line.

12. The bursting insert according to claim 1 , further comprising a central body located in a central area of the passage volume and by which center flow of the fluid is replaced.

13. The bursting insert according to claim 12 , wherein the fluid is a first fluid, and wherein the central body comprises a fluid line through which a second fluid separated from the first fluid can be passed.

14. The bursting insert according to claim 1 , wherein the bursting insert has a length in the passage direction, and wherein the length of the bursting insert is not more than three times a diameter of the bursting body or the pressure discharge line.

15. The bursting insert according to claim 1 , wherein the bursting insert is dividable in a plane extending in a direction transverse to the passage direction.

16. The bursting insert according to claim 1 , wherein the bursting insert comprises a pipe section adapted to surround part of the passage volume of a pipeline member and which can be mounted on the pipeline member in a direction transverse to the passage direction.

17. The bursting insert according to claim 1 , wherein the wall has a portion in an area of the pressure discharge line, and wherein the portion of the wall forms an attachment projecting into the passage volume and on which the bursting body is mounted.

18. The bursting insert according to claim 1 , wherein the passage volume has a flow cross-section, and wherein the flow cross-section is reduced in an area of the bursting body.

19. A bursting insert for installation in a fluid transporting pipeline or apparatus comprising a wall which at least partially surrounds a passage volume through which fluid flows in a passage direction, the bursting insert comprising a pressure discharge line extending from the passage volume, and a bursting body which seals the pressure discharge line relative to the passage volume and which, when a predetermined bursting pressure is exceeded, is transferable to a state in which the passage volume and the pressure discharge line are interconnected in fluid-conducting relationship, wherein the bursting insert is configured as a pipeline module adapted for repeated installation and removal with respect to the pipeline or apparatus permitting replacement of the bursting body, and wherein the wall has a portion in an area of the pressure discharge line, and wherein the portion of the wall forms an attachment projecting into the passage volume and on which the bursting body is mounted.

20. The bursting insert according to claim 19 , wherein the attachment has a substantially planar support surface for the bursting body.

21. The bursting insert according to claim 19 , wherein the passage volume has a flow cross-section, and wherein the flow cross-section in an area of the bursting body is reduced continuously towards the attachment.

22. The bursting insert according to claim 19 , wherein the passage volume has a flow cross-section, and wherein the flow cross-section is reduced in an area of the bursting body.

23. A bursting insert for installation in a fluid transporting pipeline or apparatus comprising a wall which at least partially surrounds a passage volume through which fluid flows in a passage direction, the bursting insert comprising a pressure discharge line extending from the passage volume, and a bursting body which seals the pressure discharge line relative to the passage volume and which, when a predetermined bursting pressure is exceeded, is transferable to a state in which the passage volume and the pressure discharge line are interconnected in fluid-conducting relationship, wherein the bursting insert is configured as a pipeline module adapted for repeated installation and removal with respect to the pipeline or apparatus permitting replacement of the bursting body, and wherein the passage volume has a flow cross-section, and wherein the flow cross-section is reduced in an area of the bursting body.

24. A modular fluid transporting system, comprising:

a pipeline having a wall which at least partially surrounds a passage volume through which fluid flows in a passage direction;

a bursting insert releasably coupled to the pipeline, the bursting insert comprising

a pressure discharge line extending from the passage volume; and

a bursting body which seals the pressure discharge line relative to the passage volume and which, when a predetermined bursting pressure is exceeded, is transferable to a state in which the passage volume and the pressure discharge line are interconnected in fluid-conducting relationship,

wherein the bursting insert is movable with respect to the pipeline to a position in which the bursting body is accessible for replacement by a user from an inside location of the wall.

25. The modular fluid transporting system according to claim 24 , wherein the bursting insert has a passage volume, and wherein the passage volume of the pipeline and the passage volume of the bursting insert in an assembled state pass into one another essentially smoothly.

26. The modular fluid transporting system according to claim 24 , wherein the pipeline is provided with a central body.

27. The modular fluid transporting system according to claim 24 , wherein the pipeline and the bursting insert are provided on their ends situated in the passage direction with correspondingly mating flanges.

28. The modular fluid transporting system according to claim 24 , further comprising a cleaning device connected to the pressure discharge line, and by which waste products of an exothermic reaction of fluid passed through the pressure discharge line can be removed from the fluid.
