VDN is the world’s largest provider of compressor pulsation and vibration services. Working with VDN results in:
- Superior reliability and smoother operations
- Reduced vibration problems and lower maintenance costs
- Responsive design and field support
This comprehensive chart outlines the required scope and options per API 618 and GMRC High Speed Compressor Guideline.
The scope applies to new (or modified) compressors. For problems with existing compressors, contact our field troubleshooting group.
Design requirement for Reciprocating Compressors
Pulsation forces in the piping system can be up to 10,000 lbf (44,500 N), causing piping failures.
For an explanation of pulsation forces and other dynamic forces on a reciprocating compressor, see our training video:
