ECTFE Lining Inspection Using Buckleys PST-100 and Vacuum Robot – A Safe, Accurate, and Confined Space-Free Solution

Invert Robotics successfully conducted the first-ever remote spark test inspection of ECTFE (Ethylene Chlorotrifluoroethylene) plastic lining in a fibreglass reinforced polyester (FRP) tank. The project used a Buckleys PST-100 – 230V A/C spark tester mounted on their proprietary vacuum robot, allowing high-precision inspection of weld seams and full surface coverage, especially in harsh chemical environments like zeolite production.

Confined Space-Free Inspection – Safe, Fast, and Reliable

Instead of exposing personnel to confined space entry, the vacuum robot followed a pre-programmed inspection route, spark testing all weld seams to detect potential leaks or defects in the ECTFE lining.

• Equipment Used: Buckleys PST-100, 230V – voltage adjusted according to liner thickness.

• HD Camera Monitoring: Live monitoring of the test probe to detect sparks at defect sites.

• Custom 3D-Printed Mount: Specially designed for stability and test accuracy on curved surfaces.

Optimizing ECTFE Lining and Welding With High-Performance Tools

To ensure the integrity of ECTFE welds and long-term chemical resistance, we recommend using the following professional plastic welding tools:

1. Weldplast S1 F – Extrusion Welder by Leister (Switzerland)

• Designed for welding ECTFE, PVDF, HDPE, PP in tanks, confined spaces, and plant maintenance.

• Lightweight, high-output, with intelligent digital controls.

• Trusted by top technical lining contractors in Vietnam.

2. Penweld 505-A & Airstream 100 Hand Welding Kit

• Ideal for sheet welding, patch repairs, and small component welding using ECTFE.

• Adjustable temperature and airflow for flexible control.

• Compatible with specialized ECTFE welding nozzles for high-strength joints.

Why Use Buckleys PST-100 for Spark Testing and Weldplast Tools for ECTFE Welding?

• Early defect detection – Prevents chemical leaks and equipment failure.

• Minimized downtime and maintenance cost – No disassembly or human entry required.

• Complies with industrial safety and environmental standards.

• Maximizes service life and chemical resistance of ECTFE linings.
