Before a TLS special container is delivered, it undergoes a comprehensive series of tests to guarantee its structural integrity, safety, and functionality. These meticulous inspections ensure that potential issues are identified and resolved early, minimizing risks during operation. Below is an in-depth overview of these essential tests:

1. Welding Test
Purpose:The welding test is critical for ensuring the structural stability of the container. It verifies the quality and strength of all welded joints, detecting defects such as cracks, porosity, or weak connections that might compromise the container’s reliability.
Testing Methods

• Visual Inspection: Examine weld seams for surface defects like unevenness, undercuts, or spatter.
• Non-Destructive Testing (NDT): Use advanced techniques such as ultrasonic, X-ray, or magnetic particle testing to identify internal defects.
• Strength Test: Apply pressure or load to assess the welds' load-bearing capacity.

Operation Stage

• Conduct immediately after completing the welding process.
• Address any defects identified before assembly to avoid further complications or costly rework.

2. Lifting Test
Purpose:The lifting test ensures the container can handle the designed load and additional stresses during lifting and transportation. It evaluates the strength and stability of lifting points and the overall structure.
Testing Methods

• Load Test: Simulate lifting scenarios by applying loads exceeding the rated capacity.
• Lifting Point Check: Verify the strength and integrity of lifting ears and points to meet international standards.
• Dynamic Testing: Assess the container's response to conditions like sudden movements or uneven loads, ensuring stability.

Operation Stage

• Perform this test after completing structural welding and assembly but before applying surface treatments.

3. Watertightness Test
Purpose:The watertightness test is essential to confirm the container’s resistance to water intrusion. This ensures the container can protect its cargo from environmental factors such as rain, snow, or humidity.
Testing Methods

• Rain Test: Use high-pressure water jets or simulate heavy rainfall to check for leaks.
• Seal Check: Focus on critical areas like door seals, welded seams, and joints to ensure they meet water resistance standards.

Operation Stage

• Conduct after installing door seals and completing welding but prior to surface treatments. This stage allows easier identification and repair of any leakage points.

4. Paint Test
Purpose:The paint test ensures the durability and visual quality of the container’s surface coating. It evaluates the paint’s adhesion, resistance to corrosion, and overall appearance under various environmental conditions.
Testing Methods

• Visual Inspection: Check for uniformity in the coating, ensuring it is free of bubbles, cracks, or peeling.
• Adhesion Test: Utilize cross-cut or pull-off methods to verify the paint’s bond to the container surface.
• Film Thickness Measurement: Measure the film thickness of the paint on the surface of the container using an electronic coating thickness gauge or a magnetic coating thickness gauge to determine the quality of the paint.

Operation Stage

• Perform this test after completing the painting process to validate the container’s visual and protective qualities.

Recommended test sequence

• Welding test → watertightness test (preliminary) → lifting test → surface treatment and painting → watertightness test (final)
• After passing all final tests, product acceptance and preparation for delivery.

Conclusion:

Each of these tests plays a vital role in ensuring the quality and reliability of TLS special containers. By addressing potential issues at the appropriate stages of production, manufacturers achieve:

• Enhanced Safety: Mitigate risks of structural failures, safeguarding personnel and cargo.
• Increased Durability: Ensure the container can withstand challenging environments and prolonged use.
• Operational Efficiency: Minimize downtime and repair costs by resolving issues before delivery.
• Compliance with Standards: Guarantee adherence to international quality and safety regulations.

Through these rigorous testing processes, TLS ensures that its special containers meet the highest standards of performance and reliability, providing customers with products they can trust for their most demanding applications.
