What is a Thermoplastic Tank Inspection?
Our thermoplastic tank inspections encompass a comprehensive approach that adheres to industry best practices and regulatory requirements, including COMAH and PUWER regulations. We conduct our inspections in line with EEMUA 225, SAFed IMG02c, and PM 86 Guidance, ensuring the integrity of your tanks.
Thermoplastic tanks are made of materials that are resistant to corrosion and chemicals, but they can still develop cracks or other damage over time. We employ advanced non-destructive testing (NDT) techniques, such as ultrasonic thickness testing (UT), water-based fluorescent dye penetrant crack detection, and spark testing (AC or DC holiday testing), to identify potential defects and damage that may not be visible to the naked eye.

Key benefits
Ensuring safety
Regular inspections can help to identify any potential problems before they lead to leaks or other safety hazards.
Extending service life
Thermoplastic tanks can last for many years, but they will eventually need to be replaced. Regular inspections can help to identify any signs of aging or wear and tear, so that repairs can be made to extend the tank's service life.
Compliancy
In some industries, such as the chemical and oil and gas industries, there are regulatory requirements for inspecting thermoplastic tanks. Regular inspections can help to ensure that your tanks are compliant with these requirements.
