Container weld inspections are crucial to ensure structural integrity and safety. Among the non-destructive testing methods available, Magnetic Particle Inspection (MPI) stands out. This technique utilizes magnetic powders to reveal defects and discontinuities in ferromagnetic materials without causing any damage.
 
The process of MPI involves magnetizing the ferromagnetic workpiece, which leads to localized distortions in the magnetic field lines when discontinuities are present. This results in a leakage magnetic field that attracts magnetic powders applied to the surface. When appropriately illuminated, these powders form visible indications, allowing for the identification of location, size, shape, and severity of any defects.
 
For effective flaw detection, TLS employs black magnetic paste during MPI. This specific approach boasts high sensitivity in detecting even the smallest surface imperfections. The procedure comprises the following steps:

1. Application of Magnetic Levitation: A slow and controlled application of magnetic levitation over the workpiece prevents the washing away of magnetic imprints.
2. Utilization of Fixed Devices: Implementing fixed devices streamlines the process, ensuring ease of operation and high efficiency.
3. Demagnetization: This step reduces residual magnetism in the inspected workpiece, enabling subsequent processing or normal usage.
4. Removal and Drying: After the magnetic particle inspection, any residual magnetic levitation on the surface is removed and dried.

 
All our Quality Assurance personnel undergo rigorous certification examinations. At TLS, we uphold an unwavering commitment to product quality, delivering only after thorough confirmation that our offerings align with stringent quality inspection standards.

During the video inspection of explosion-proof pressure containers, several critical aspects are thoroughly examined to ensure their safety and compliance with regulations. The inspection process includes the following key areas:

• 1. Visual inspection

Including the inspection of the positive pressure explosion-proof control system and various major accessories for installation. At the same time, it is also necessary to check the details of the sealing of the positive pressure container and whether the labels are in place. We will check them one by one according to the customer's configuration

• 2. Insulation resistance test
• 3. Functional check

Positive pressure explosion-proof containers usually have 3 modes：Automatic mode, Bypass mode, Manual mode.
Check the functions of all modes, and the functional tests of all modes will be carried out one by one according to the regulations on the FAT file.
Automatic mode: normal use in hazardous areas
Bypass mode: can only be used in safe area
Manual mode: for emergency use only
In "bypass mode" and "manual mode", the explosion-proof fan can be started manually only when the air inlet and outlet valves are fully opened; when the air valve is not fully opened, the manual switch of the explosion-proof fan is invalid.

Positive pressure containers are essential safety equipment used in industries operating in explosive environments. Before these containers are shipped, several crucial preparations and tests are conducted to ensure their quality and functionality. This article provides insights into the pre-shipment preparations for positive pressure containers, giving you a better understanding of the measures taken to ensure a safe and reliable product.

• Visual Inspection and Quality Checks:

One of the initial steps in preparing positive pressure containers for shipment involves a comprehensive visual inspection and quality checks. Engineers and quality inspectors meticulously examine the container's external appearance, equipment fittings, and signage. They verify that the container meets design specifications, adheres to safety standards, and fulfills customer requirements. This meticulous inspection guarantees the container's overall quality and reliability.

• Functional Testing of Critical Systems:

Before shipping, positive pressure containers undergo thorough functional testing of their critical systems. Engineers and technicians evaluate the performance of essential components, such as the CPFG control system, temperature sensors, smoke detectors, Manual Call Points (MCP), Emergency Shutdown (ESD) buttons, pressure differential gauges, fire dampers, and fans. This rigorous testing ensures that all systems operate as intended, creating a controlled and safe environment within the container.

• Customization to Meet Specific Needs:

Positive pressure containers are often customized to meet the specific needs of different industries and customers. As part of the pre-shipment preparations, customization is done to fulfill these unique requirements. This may involve incorporating additional safety features, modifying equipment placements, or adapting the container's functionality. By tailoring the container to meet specific needs, it ensures optimal safety and operational efficiency for the end user.

• Documentation and Compliance:

Another important aspect of pre-shipment preparations is ensuring proper documentation and compliance. Engineers and quality inspectors verify that all necessary documentation, including certifications, test reports, and compliance with industry regulations, is in order. This ensures that the container meets the required standards and can be safely transported and installed at its destination.

• Final Checks and Packaging:

Before the positive pressure container is shipped, a final round of checks is conducted to ensure that everything is in order. This includes verifying that all equipment is securely fastened, labels and markings are clear and accurate, and any necessary protective measures are in place to prevent damage during transit. The container is then carefully packaged to ensure it arrives at its destination in optimal condition.

The design and construction of offshore containers, as well as their lifting equipment, are subject to strict regulations and standards to ensure their safety and reliability in the challenging operating environment of offshore oil rigs. The DNV 2.7-1 and EN 12079 standards set out the requirements for the design, manufacture, testing, and certification of offshore containers, including their top corner piece structure and lifting equipment.
 
To ensure that these containers are safe and reliable, a series of tests are conducted. These tests include:
 
1. All Point Lifting Test: This test involves placing a weight of 2.5R-T inside the container and measuring the deformation of the bottom frame while the container is lifted at all four corners for 5 minutes. After 5 minutes, the deformation of the bottom frame is measured.

2. Two-Point Lifting Test: In this test, the weight inside the container is reduced to 1.5R-T, and the deformation of the bottom frame is measured.

3. Fork Pocket Lifting Test (if applicable): If the container has fork pockets, this test involves adjusting the weight inside the container to 1.6R-T and measuring the deformation of the bottom frame while fixing the fork arm with angle pieces or jacking up the container and standing still for 5 minutes. For small containers, the container is directly lifted with a forklift and held still for 5 minutes, after which the data is recorded.

4. Vertical Impact Test: For this test, the weight inside the container is adjusted to the R-T state.To lift a container, appropriate shackles and wire rope slings should be installed on all four lifting points according to the design requirements specified in the drawing. The lifting point of the wire rope should be adjusted to ensure that the container is at a certain slope. When lifting the container, it should be unloaded quickly between the hook of the crane and the wire rope, and the container should be pulled by the rope to prevent it from swinging randomly. Once the container is lifted to the cement surface, adjust the tilt angle of the bottom side beam of the box by 5 degrees. The highest point of the bottom frame should not be higher than the lowest point by more than 400 mm. Make sure that the lowest point of the bottom frame is at least 5 cm away from the ground to operate the quick shackle, allowing the container to free fall. After the test is completed, inspect all structural parts of the container for any cracks or damage.
 
The main purpose of the tests is to examine the impact of the lifting and placing of containers at sea to ensure that the cabinet can withstand the damage caused by the impact. 

Unlike ordinary dry cargo containers, which are primarily used for land transportation, offshore containers are specialized containers used on offshore oil rigs;  Therefore, there is a well-established set of European standards for their design and manufacture, including DNV 2.7-1 and EN 12079.
Marine containers are mainly used on marine drilling platforms, where the operating environment is demanding and frequent hoisting is required, which places high requirements on container hoisting equipment.
All four corners of the top of the container have a top corner piece structure. The top corner piece structure consists of a standard container top corner piece, a lifting lug, and a reinforcing piece.
The uplifted ears are located on the inner side of the top horn, adjacent to it, and are arranged and fixed to it. The four-point or two-point lifting of a container can be performed by means of a hoist, and therefore there is a higher strength requirement on the hoist itself as well as on the top of the box in which the hoist is mounted. The lifted lug material must have low-temperature shock resistance properties.
The reinforcing piece consists of a bottom plate for the lifting lug, and a coaming plate arranged on three sides of the bottom plate of the lifting lug. The setting of the coaming plate not only strengthens the lifting ear area but also protects the lifting ear.
When lifted, a special sling is used, the shackles are passed through the eye holes and locked firmly, then the sling is lifted through the main ring of the sling.

Compared with the design durability of C5-H of 15-25 years, the corresponding dry film thickness of C5-VH is 320μm, and the design life of C5-VH is over 25 years. 
Specific parameters are as follows: 

• Shop primer (pretreatment) 10 μm 
• Epoxy zinc primer (secondary primer) 100 μm 
• Epoxy intermediate coating 150 μm 
• Polyurethane finish 60 μm
