Piping and Bottle Restraints

Problem:

A major problem that gas transmission and petrochemical companies are facing is piping fatigue and failure caused by vibration.

High frequency (ultrasonic and hypersonic) gas pulsations that occur at natural gas transmission line compressor stations cause metal fatigue in the piping and valves. Problems also arise from "water-hammer" type shock impulses that occur. Excessive vibration therefore constitutes a great threat to the safety and reliability of gas compression and liquid pump systems.

The vibrations not only cause rupture of piping, but also stud and bolt branch piping breakages, header and manifold breakages, and unwanted noise.

Solution:

To eliminate excessive vibration and design a safe and reliable piping system, a properly designed mechanical restraint is required.

The application of Fabreeka® Preformed Fabric Pad within these mechanical restraints can provide:

• increased damping of piping vibrations
• increased thermal flexibility
• reduction of unwanted noise

It also prevents:

• corrosion caused by metal-to-metal contact
• high stress points
• fretting
• galvanic action
• non-uniform clamp contact pressure.
