Industry experience over the years has consistently shown that pipe stress is one of the most overlooked causes of repeated alignment failure.
Even when laser alignment is achieved within tolerance, pipe loading can:
• Increase bearing and seal failure risk by 30–50%
• Raise vibration levels by 20–40% after startup
• Reduce pump and coupling life by up to 40%
• Cause alignment to drift again within days or weeks
Predictive Maintenance may flag vibration or misalignment but unless pipe stress is released, the correction will not hold.
This short blog explains a real field situation where:
• Flanges were not straight
• Pipe loading prevented alignment correction
• Stress release restored proper alignment and machine stability
