At Flexilatina de Colombia, with more than 15 years of experience in industrial sealing solutions under our DINASEAL® brand, we have identified that a large proportion of leaks, unscheduled stops and premature failures are not due to packaging defects, but to an incorrect selection compared to the actual operating condition.
Choosing “similar” packaging or solely based on price is one of the most costly mistakes in the industry. Below, we present the most frequent mistakes when selecting industrial packaging and how to avoid them using solid technical criteria.
- Select packaging only by nominal pressure
Common mistake:
- Choose the gasket solely based on the class of the flange, without evaluating the temperature and its interaction with pressure.
Consequence:
- Accelerated degradation of the material, loss of sealing and eventual leakage of the process fluid.
How to avoid it:
- Evaluates the pressure vs temperature curve simultaneously.
- Consider operating peaks, starts and stops.
- Use manufacturer’s technical sheets and recommendations, not just generic tables.
- Do not consider the chemical compatibility of the fluid
Common mistake:
- Install standard gaskets in different materials without validating their chemical compatibility with the process fluid.
Consequence:
- Chemical attack, swelling, embrittlement or partial dissolution of the packaging.
How to avoid it:
- Check chemical compatibility between the fluid and the packaging.
- Take into account contaminants, traces and process variations.
- Consult material-specific chemical matrices.
- Use the same packaging for all applications
Common mistake:
- Standardize a single type of packaging “for everything” for logistical ease.
Consequence:
- Unnecessary overdesign in some lines and critical flaws in others.
How to avoid it:
- Adjust the type of packaging according to the operational risk and the real conditions of each stage of the process.
- Get advice from specialized technical personnel who recommend the best alternative.
- Ignore the surface condition and rigidity of the flange
Common mistake:
- Select the packaging without considering the surface finish and type of flange
Consequence:
- Persistent leaks even with correct torque and good tightening procedure.
How to avoid it:
- Check the recommended surface finish for each packaging.
- Consider metallic or semi-metallic gaskets on rigid flanges.
- Avoid soft gaskets in high-responsibility systems that require high clamping loads.
- Choose the packaging without considering the installation method
Common mistake:
- Select a gasket that is suitable in theory, but impossible to seal with the available torque or the procedure applied in the field.
Consequence:
- Forced installations, packaging damage or poor sealing.
How to avoid it:
- Ensures that the gasket is compatible with the achievable torque.
- Relates packing, bolts, lubrication and tightening procedure.
- Follows good practices given by ASME PCC-1.
- Prioritize cost reduction when choosing packaging
Common mistake:
- Choose the most economical packaging without evaluating its impact on maintenance, unscheduled stops and safety
Consequence:
- Increase in operating expenses, recurring leaks and operational risk.
How to avoid it:
- Correctly selected packaging reduces stops and rework.
- Reliability is always more profitable than constant replacement.
- Do not prioritize cost over product quality.
