Thief Hatch Inspection

Visual Integrity. Safety First. Production Ready. 

At Quadco, our Thief Hatch Inspection service ensures the safety, compliance, and long-term reliability of your tank battery systems. We perform detailed visual inspections of internal soft goods including gaskets, seals, and latches on thief hatches and tank valves, identifying wear, corrosion, or other failure risks before they become costly problems.

What We Do: 

• Inspect internal soft goods (gaskets, O-rings, seals) for signs of degradation or failure. 
• Evaluate latch mechanisms and alignment to ensure a proper seal. 
• Check for corrosion, cracks, and wear inside and around the hatch. 
• Verify tank valve functionality in coordination with thief hatch condition. 
• Document all findings with recommendations for maintenance or replacement. 

Why It Matters: 

• Environmental Compliance: Reduce emissions and meet regulatory standards by ensuring hatch seals are tight and functioning. 
• Operational Efficiency: Prevent leaks and pressure issues that compromise tank performance. 
• Safety Assurance: Minimize vapor exposure risks for personnel and surrounding communities.
