HOW DO SNUBBER SUPPORTS WORK IN DYNAMIC CONDITIONS

⬆️ Snubbers are activated when either a threshold acceleration (hydraulic snubbers) or threshold velocity (mechanical snubbers) is reached. At that point, the snubber is activated either via a valve system (hydraulic snubbers) or spring loaded mechanical stop (mechanical snubbers) to lock in position and act as a restraint device to prevent further movement of the pipeline.

Momentum Technologies provides a high frequency tuned mass damper; the Momentum TMD. It is a state-of-the-art product for mitigating resonance vibration above 20Hz. These unique characteristics makes the Momentum TMD very suitable for solving vibration problems in small bore gas piping and machinery piping.

Momentum TMD – INSTALLATION

The Momentum TMD is clamped to the pipe or structure to be damped, with the integrated clamp included in the delivery. The mounting can be made during operation and no hot work is needed for the installation. The Momentum TMD is free hanging and do not need any support or other foundation.

The mono-clamp design enables the damper to be fitted to pipes at various locations, for example close to bends. Momentum Technologies do also provide customized clamp or attachement solutions, for example brackets suitable for installation at valve flanges.

ADVANCED PIPE STRESS ANALYSIS for black carbon reactors

Piping designers traditionally route piping by layout, process, flow constraints (such as pressure drop) and other constraints but often do not take vibratory service into consideration. Pipe stresses are often not sufficiently considered while routing and supporting dynamics piping systems, especially when providing adequate flexibility to absorb thermal expansion/contraction of pipes. Upon completion of this analysis, Compression Dynamics will present you with proper modifications to bring piping systems into API or ASME codes.

In order to properly design a piping system, the engineer must understand both a system's behavior under potential loadings, as well as the regulatory requirements imposed upon it by the governing codes.

A pipe rack with elevated risers and expansion loops. Red pipe in the middle is the full system. Top and bottom pipes in blue are details. Motions are shown below.

Motion of pipes in the pipe rack with elevated risers. Attention is paid to optimizing the design of the loop while keeping motions and loads in the rest of the system within limits.

A tower with a guided flexible pipe connection. The guided connection allows the flexibility required in the nozzle while limiting the loads applied to the vessel nozzle. Modelling the flexibility of the nozzle and accounting for the different possible temperatures of the piping system and tower is required for successful analysis.

Stress analysis of a pump skid from storage towers to dual pumps. The temperature distribution of the piping varies depending on which pump or pumps are running. Here the pipes leading to the operating pump are hotter than the standby pipes. Multiple load cases are required to ensure the piping design is acceptable.
