Generate Powerful Savings with Coupling Recertification

Ensure your power equipment stays in peak operating condition and minimize the costs of unplanned downtime, replacement parts and emergency labor with coupling recertification.



Applications and Industries
ethylene plants
oil and gas
petrochemical plant
refinery


Why Recertify?

1800 RPM
 

Recertification is performed on high performance couplings, typically those with API 671 specifications, rotating at 1,800 RPM or higher.


90 Percent
 

Nearly all couplings taken out of service can be recertified, which plant operators with significant cost savings compared to purchasing new couplings.


50 percent
 

Recertification results in couplings that are like new—for about half the cost.


60 percent
 

Recertification lead times are 60% less normal lead times for a new coupling, which enables plant operators to minimize unplanned downtime and keep production on schedule.



Six Steps to Recertification
 

Number 1
 

Couplings are disassembled and glass bead cleaned to remove surface corrosion and other surface anomalies.

 
Number 2
 

A complete mechanical and metallurgical evaluation is performed to ensure all major components meet original specifications and are suitable for continued service.

 
Number 3
 

Disc packs (where applicable) and all hardware to include bolts, nuts, washers and shims are replaced.

 
Number 4
 

As needed, components can be manufactured to replace those deemed unserviceable or require upgrade.

 
Number 5
 

Couplings are then reassembled and re-balanced in accordance with the OEM specifications.

 
Number 6
 

Custom preservation packaging for long-term storage.



What Recertification Does

Recertification brings the coupling back to like-new condition from damage that may have occurred during operation — including conditions that may not be visible with the naked eye. Factors that contribute to coupling wear include:






increased output demand

Damage identified during recertification can also be an early indicator of more significant problems in other equipment:


Disc pack fretting could result from resonant torsional frequency.


Cracks in the outer disc may signal that the coupling is operating under excessive misalignment.


Equipment misalignment resulting from foundation settling in aging facilities.



Unlock the Value of Coupling Recertification

By incorporating coupling recertification into maintenance plans for high-performance couplings, plant operators can be ensured peace of mind while taking a proactive approach to protect their businesses from operational disruptions and losses.
