Description

A pipe clamp device for pipeline vibration reduction

technical field

Background technique

At present, in the pipelines conveying fluid medium, especially the high-pressure pipelines connected with moving equipment, such as the inlet and outlet pipelines of multi-stage reciprocating compressors, the stress situation is complicated. Working under variable loads may cause fatigue damage in light cases, or cause accidents such as pipeline leakage and explosion in severe cases.

The main function of the pipe clamp is to provide constraints and increase the rigidity of the system. Its size is mainly determined by the size of the pipe, the medium to be transported and the load. The principle is that the structure should be as simple as possible and the weight should be as light as possible under the premise of meeting the load capacity, so as to facilitate processing, handling and installation. , the pipe clamp in the pipeline must have sufficient strength. Except for the rigid connection of the limiting pipe clamp, the pipe clamp used in other occasions also requires a buffer structure to bear alternating loads. Most of the pipe clamps in the prior art solutions only increase the structural stiffness, and cannot effectively control the stiffness value, or realize stiffness control in one direction at most, and cannot play a role in piping systems that vibrate more violently in multiple directions. Good vibration damping effect.
