Pipe support

from Wikipedia, the free encyclopedia
Pipelines with various types of pipeline supports in the Dürnrohr power plant

The pipe support is used to support and guide a pipeline and to absorb and forward forces resulting from pipelines.

A pipe bridge or pipeline bridge is also a pipe support. This design is used to route individual or multiple pipes above ground over greater distances.

conditions

The aim of pipeline planning is to select and position the brackets in such a way that a pipeline remains safely in its position under all circumstances, no damage occurs in the supporting building or the connected apparatus and machines, and the line itself does not cause excessive voltages at any point Takes damage. In most cases, the removal of the stands weight force in the foreground, from the weight of the construction, the weight of the transported medium and optionally the snow load composed. In many cases, forces have to be removed that arise from hindered thermal expansion , reaction forces from deflection and other causes. Apparatus and machine nozzles must be kept free of force. Furthermore, vibrations in pipelines due to wind or earthquake forces must be limited to a permissible level.

In many cases, the pipe supports must allow a certain degree of freedom of movement so that the pipe can expand with changing temperatures .

Components and types

Resilient support for a pipeline in a disused power plant

Pipe supports usually consist of one or more pipe clamps , which in turn are supported on a substructure made of steel construction profiles. In other cases, the pipeline can be hung with pipe hangers . The entire construction from the pipe clamp to the pipe bearing is also referred to as a load chain.

The flexibility of pipelines in the direction of gravity is provided by resilient pipe supports or pipe hangers. These are special spring pots with adjustable spring tension that are inserted between the pipeline and the substructure.

Structurally, the pipe supports are divided into

  • Constant hangers, such as constant supports and constant hangers
  • Spring elements, such as spring hangers, spring supports
  • Dynamically loaded components, such as shock absorbers, articulated struts
  • Pipe-enclosing components, such as horizontal clamps, vertical clamps and tubular brackets
  • Roller bearings, pipe supports
  • Connection elements such as threaded eyelets, threaded brackets, turnbuckles
  • Construction connections, such as traverses , ceiling hangers, support brackets, welding eyelets, tension clamps

Degrees of freedom

Pipe supports are also differentiated according to degrees of freedom.

  • Fixed point holds this point in the line absolutely firmly
  • Loose point allows horizontal sliding in all directions (load transfer)
  • Longitudinal guide allows sliding in the direction of the pipe axis
  • Cross guide stops pushing in the direction of the pipe axis, but movement across it is possible
