Description:

Emergency protection of pipelines and equipment intended to prevent accidents due to hydraulic vibration and shock loads, as well as forced oscillations and resonance phenomena in pipelines.

 


State of the problem:

In the process of operation of pipeline systems for various purposes inevitably arise intense wave (pressure fluctuation, hammering) and vibratory processes that lead to the occurrence of variables in time of the stresses in the walls of pipelines and the emergence, over time, fatigue and corrosion-fatigue cracks in areas of weld joints or any subtle defects, which are stress concentrators (scratches, burrs, etc).

All of these factors are usually not accounted for when designing piping systems. In addition, in the regulations of many industries, including housing and utilities, does not only limit the pressure pulsation, but also restrictions on vibration.

Therefore, one of the major challenges in ensuring reliable, economic and trouble-free operation of pipeline systems is the prevention and elimination of pressure fluctuations and associated vibrations of piping, fittings and equipmentarising mainly as a result of periodic character of pumping units. Upon occurrence of resonance phenomena due to coincidence or proximity of the natural frequencies of the pipeline with the driving frequency and amplitude of pressure pulsations and vibrations can multiply and lead to the disclosure of flanged joints, rupture of welded joints, leakage of transported products into the environment with serious economic and environmental consequences.

According to experts, the causes of rupture of pipelines are:

60% of cases – hammering, pressure drop and vibration

25% – corrosion processes,

15% – natural phenomena and force majeure.

 

The advantages of the devices for emergency protection of pipelines:

– reduction of the accident rate of pipelines and equipment by 85%,

increase lifetime of pipelines in 1,5 – 2 times,

– damping of the wave and vibration processes in 5-10 times

performance: less than 0.005 seconds

– no loss of working medium,

environmentally friendly,

– no additional hydrodynamic resistance,

energy independence,

– small size,

does not require maintenance during operation,

– easy to install.

 

Application:

Extraction and transportation of oil and gas, energy, industry, housing and communal services.
