The Alternative to Replacement
Fatigue failure is the limiting factor for most welded steel structures. Instead of costly component replacement, Syntegris applies Pneumatic Impact Treatment (PIT) to introduce beneficial compressive stresses, extending the fatigue life of your asset by up to 10x.
Pneumatic Impact Treatment (HFMI)
On-Site Weld Improvement Service
Technical Application
Scope of ServiceWe provide a turnkey service that includes equipment rental, qualified operators, and QA/QC documentation.
- Crack Arrest: Treatment of existing micro-cracks to stop propagation.
- Weld Geometry Improvement: Smoothing the weld toe transition to reduce stress concentration factors (SCF).
- Residual Stress Engineering: Inducing compressive stress up to 2mm depth.
- Speed: High treatment speed (approx. 30cm/min) minimizes downtime.
Engineering Validation
Simulation-Based Integrity Assessment
Fatigue Analysis (FEA)
Proof of ConceptBefore we touch the steel, we verify the results digitally. Using SDC Verifier, we calculate the current utilization factor and simulate the life extension gained from PIT.
We certify our calculations against:
- DNV-RP-C203
- Eurocode 3
- IIW Recommendations

Required Data
Our engineering team reviews every request to ensure feasibility. Please have the following information ready if possible:
Type (e.g., Crane, Bridge, Jacket) and Material Grade (e.g., S355).
Approximate length of welds to be treated (in meters).
Is rope access required? Is the site onshore or offshore?
Preventive treatment vs. Repair of detected cracks.
