Engineering / Technical Testing

Various Testing by our Well-experienced Engineers and Technicians
WCS offers engineering and technical validation services to ensure all applications meet international standards such as ASME PCC-2. From pressure retention tests to surface preparation validation, our team collaborates with clients to ensure safe, cost-effective solutions. Whether it’s a one-off repair or a long-term infrastructure plan, our support helps maximize compliance, reliability, and operational performance.

i. Pull-Off Adhesion Test (Dolly Test)

Validating Coating Integrity with Precision

WCS performs standardized pull-off adhesion testing (also known as dolly testing) to assess the bond strength of applied coatings, wraps, and repair materials. This test involves applying a controlled tensile force to a dolly glued onto the coated surface, measuring how well the system adheres to the substrate.

  • Ensures surface preparation quality
  • Verifies the effectiveness of VAM composite applications
  • Compliant with international standards (ASTM D4541 / ISO 4624)
  • Reduces risks of coating failure and delamination

Whether for pipeline repairs or structural reinforcement, pull-off testing is a critical part of our quality assurance process—ensuring long-term performance and reliability in high-stakes environments.

ii. Hydrostatic Pressure Test (Hydrotest)

Proving Repair Strength Under Pressure

At WCS, we perform hydrostatic pressure testing (hydrotest) to validate the strength and sealing capability of our composite repair systems. By injecting pressurized water into the repaired pipeline or component, this test simulates real operating conditions—ensuring the system can withstand the required pressure levels safely.

  • Confirms the integrity of composite repairs
  • Verifies leak-tightness and mechanical strength
  • Ensures compliance with pressure class specifications
  • Provides assurance before system recommissioning

Safety is our priority. Every hydrotest is conducted under strict safety protocols—ensuring personnel and asset protection during high-pressure validation. With WCS, you can operate with confidence, knowing your repair has passed the toughest test.

iii. Hardness Test (Durometer)

Verifying Material Cure and Structural Integrity

At WCS, we conduct hardness testing using a durometer (Shore D scale) to evaluate the surface hardness of cured composite materials. This test ensures that materials such as epoxies and reinforced systems have properly cured and meet mechanical strength requirements.

  • Uses Shore D scale for high-strength composite materials
  • Verifies full cure and surface integrity before service
  • Assesses resistance to indentation and surface wear
  • Ensures quality control and repair reliability
  • Non-destructive, fast, and field-deployable

Our engineers typically use a trusted, calibrated and accurate tool for field hardness evaluation. By integrating hardness testing into our QA workflow, we deliver dependable repairs that meet industry and safety standards – ensuring your asset is ready for operation.

iv. Dry & Wet Film Thickness Test

Ensuring Optimal Coating Performance

At WCS, we perform both Wet Film Thickness (WFT) and Dry Film Thickness (DFT) tests to ensure coating systems are applied within the specified range—delivering long-term protection and performance in aggressive environments.

Wet Film Thickness (WFT)

  • Measured immediately after coating application
  • Helps applicators apply the correct thickness in real time
  • Prevents under- or over-application
  • Uses wet film combs or gauges

Dry Film Thickness (DFT)

  • Measured after the coating has cured
  • Verifies that the coating meets the specification
  • Critical for corrosion protection, chemical resistance, and mechanical strength
  • Non-destructive testing using magnetic or eddy current gauges (e.g., Elcometer, PosiTector)
