Visual inspection and non-destructive testing are commonly used to inspect container welds. Magnetic particle inspection is one of the types of non-destructive testing. Magnetic particle inspection is a method of observing defects using magnetic powders as a display medium. After the ferromagnetic material workpiece is magnetized, as the existence of discontinuity, the magnetic field lines on the surface and near the surface of the workpiece are locally distorted to generate a leakage magnetic field, which adsorbs the magnetic powder applied on the surface of the workpiece and forms a visible magnetic field under suitable illumination，and the location, size, shape, and severity of the discontinuities are shown.

TLS normally uses black magnetic paste for flaw detection. This method has high sensitivity to detect small defects on the surface of the workpiece. The steps are:

1. Pour and spray the magnetic levitation over the workpiece to be examined, and the flow rate of the levitation should be slow to prevent the magnetic imprints from being washed away.
2. Use a fixed device. It is easy to operate and has high efficiency.
3. Demagnetization. Reduce residual magnetism in the inspected workpiece so that it can be processed or used normally.
4. After magnetic particle inspection, residual magnetic levitation on the surface is removed and dried.Our QAs are all certified through strict examinations.

TLS attaches great importance to the quality of products and will only deliver products to customers after confirming that the products meet the quality inspection standards.

Containers are no longer a traditional transport tool that can only be used to carry goods. More and more container types are known to us. In order to meet the needs of different container types, the correct selection of doors has also become an important step in the design process.
 
Before choosing, please answer the following questions：
What does this container need to be used for?
Do large-sized items need to be placed in the container?
Are containers used as offices or homes?
Do we need to go inside the container frequently?
 
5 Basic Types of Container Doors for Your Reference
1. Cargo door
"Original" doors for shipping containers. Usually installed at the end of the container. These heavy duty doors are weatherproof and very secure. They open outward, and the secure cam and locking system are robustly designed to deter theft and reduce the risk of damage from inclement weather and other environmental threats.
Applicable environment：Large objects need to be easily placed in the container
Features: Affordable, no modification or installation required.

2. Personnel door
Use in case of storing smaller items or as a laboratory, office, house etc. They are usually installed on the end face of the container and have good sealing performance. According to the different use environments, there are doors that meet the level of B30 and A60.
Applicable environment: It is frequently used for easy entry and exit of people, (movable office building, portable office station, laboratory shipping container)
Features: Easy to use, various styles and standards to choose from

The design of any container building should be tailored to the specific needs of each project.

For the functions of sea containers, such as transporting refrigerated, living or working, etc., it is necessary to carry out modifications to meet the requirements of thermal insulation and fire protection of the container.  Normally, the sea land containers provided by TLS can comply with the A60 standard.
Classification society standard A60 level specific requirements:

1. Steel or equivalent material, the thickness is 4.5±0.5mm.
2. Appropriate anti-flexion reinforcement, where the distance between the aggregates should be about 600 mm.
3. Made of approved non-combustible materials, so that within 60 minutes, the average temperature rise of the backside does not exceed 140℃, and the temperature rise of any point on the backside does not exceed 180℃.

What type of refractory material is A60 fireproof?
The material is required to have a certain rigidity and fire resistance for more than 1 hour, during which time the integrity is maintained to prevent the passage of smoke and flame.
Rock wool and ceramic fiber wool are two different materials, both of which can be used as insulation materials for A60 fire protection but must be approved by the relevant classification society.

As early as the 1950s, the motor center was widely used by the automotive industry to control manufacturing, and many industrial motor companies used motor control center to install directly and other equipment at the location center. Although many motor control centers（MCCs） are located directly on the factory floor, there are additional benefits to having the motor control center located in the shell of a shipping container.

• Protect the motor control center, which can improve it to a certain extent and prolong the service life of the internal equipment of the motor under the condition of no interference and operation under the temperature, and improve the operation efficiency of the whole system.​
• The outer shell of the shipping container is more convenient for transportation and transfer, and the installation is convenient and fast, which provides possibility for temporary call or emergency replacement.​
• The traditional work of MCC system and maintenance is simplified. The containerized motor control center usually carries out integrated control on the assembled equipment. The monitoring and regulation of the system also improves the efficiency of daily maintenance and use.​
• Because of the protection from the shell, motor control center for the environment becomes less demanding, TLS provide containerization motor control center housing can be according to your requirements designed to conform to the DNV2.7-1, A60 fire, IECEx | ATEX explosion-proof, can be used in ZONE1 | ZONE2 environmental standards.

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.

Energy storage containers are portable energy storage devices that are often used for power backup. Thermal dissipation in energy storage batteries is a key factor in determining their performance, safety and lifetime. In order to maintain the temperature in the container at the normal operating temperature of the battery, the main heat dissipation structures of current energy storage container can be classified into two categories: air cooling and liquid cooling.

• The air-cooled system uses air as a cooling medium and uses convective heat exchange to reduce the temperature of the battery. The air-cooled system has the advantage of being simple in construction, easy to maintain and low in cost.  The disadvantage is that air has a low specific heat capacity and a very low thermal conductivity, which makes air cooling typically used in applications with low heat production rates.
• Liquid cooling systems use liquid as a cooling medium and carry away the heat generated by the battery through convective heat exchange. Its structural form: one or more bent water pipes buried within an enclosure wall. When in use, connect the inlet and outlet of the pipe to an external circulating water supply system. The circulating water supply system sends cold water to the pipes and flows through them.  The cold water flowing along the pipe absorbs the heat from the wall, which is dissipated by the battery. And then the cold water heats up, and the heated water returns from the outlet of the pipe to the circulating water supply system.

How do you choose between air and liquid cooling? The choice of power storage temperature control technology is the result of a comprehensive consideration of factors such as safety, economy, battery pack design, and the environment in which it is located, rather than a simple consideration of cooling performance.

Large-scale power storage technology is the key technology for smart grid, new energy generation and grid connection, power load shifting and valley filling. Lithium-ion batteries have been widely used in many fields due to their high energy density, low self-discharge rate, smooth discharge voltage, long cycle life and other advantages, and the application of lithium batteries in large-scale power storage systems will become an inevitable trend in technology development. In order to ensure the efficient and safe application of lithium-ion solar battery storage (Battery Energy Storage System, BESS), all components of the system must be integrated and optimized, and managed and controlled in a reasonable and effective manner.
 
The battery management technology and system integration technology of energy storage systems can be developed to improve the safety, reliability and service life of the battery system and promote the popularization and application of large-scale power storage. The key technologies include:
(1) advanced battery management technology ;
(2) temperature monitoring and management technology;
(3) state of health (SOH) monitoring technology;
(4) system integration technology.
