What is Trust Force?
The trust force is actually the reaction force that comes from the passage of the fluid. In fact, this force can be expressed as the product of the effective surface of the blues by the pressure of the passing fluid. This force is very important in the design of the accordion joints. Therefore, if a pipeline system designer wants to use the accordion connection in a direction, he or she must calculate this force accurately and make the necessary arrangements to prevent the problem from occurring.
A flexible accordion connector is known as the best tool for attracting the movement of pipelines. These movements can be caused by changes in temperature and vibration rate. Whether or not there is an accordion in the pathway, there may be a trust force in it and this cannot be ignored. When this force is applied to the pipe, the blues are drawn towards it. Anchor can be used to avoid such an issue.
In many cases, the force of the trust is greater than the spring coefficient of the connection. To get to know this force better, you need to assume that the two sides of the connection are closed. In this case, if you apply force from inside the connection in an outward direction, the connection tends to be drawn to the force. What would you do to repel this power?
To repel this force, the pipeline designer must tighten the elbow of the changing or end of the pipe using a fixer or anchor. If the anchor is not possible, you can use appropriate accordion fittings that work to adjust the pressure.Of course, this is true if you have chosen a simple accordion connection for your route. In more complex situations, tools such as the use of harnesses, guardrail rings, joints and … Used. It is worth noting that the thrust force is applied to the connection before the tube moves (caused by temperature changes).
