Controlled Bolting Services for Industrial Turnarounds
Why Controlled Bolting Matters During Turnarounds
Bolted joints hold critical systems together. But inconsistent torque, skipped sequences, or worn tools can lead to leaks, vibration issues, or premature gasket failure after startup.
Controlled bolting uses defined bolting procedures, calibrated tools, and trained technicians to apply the precise load to every fastener—whether it’s a refinery flange, pressure vessel manway, or turbine casing. Industrial Bolting brings on-site bolting and tensioning crews directly to your jobsite, along with technical support that keeps shutdown work moving safely and efficiently.
Industry guidance from ASME PCC-1 emphasizes controlled tightening methods to improve gasket performance and reduce leakage risk. OSHA also requires proper bolting practices and documented procedures when working on pressurized or hazardous systems. These standards aren’t paperwork exercises—they protect uptime, safety, and your bottom line.
A Simple Turnaround Bolting Checklist
Before your shutdown begins, make sure you have:- A joint list with torque or tension specifications
- Verified bolt sizes and material grades
- Defined tightening sequences for critical flanges
- Calibrated torque or tensioning tools
- Staged tooling and spare accessories on site
- A trained crew familiar with your safety requirements
What Can Go Wrong During Turnaround Bolting
- Reusing bolts or gaskets without verification
- Missing or outdated torque calibration certificates
- Crews are tightening “by feel” instead of procedure
