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:

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:
- 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.
- Use a fixed device. It is easy to operate and has high efficiency.
- Demagnetization. Reduce residual magnetism in the inspected workpiece so that it can be processed or used normally.
- After magnetic particle inspection, residual magnetic levitation on the surface is removed and dried.Our QAs are all certified through strict examinations.

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

3. Roll-Up Doors
Sometimes referred to as overhead doors, they are welded to the container walls, are usually rolled up from the bottom, can be locked, are easy to maneuver and are relatively lightweight.
Applicable environment: Used to store large objects or equipment
Features: Save space, easy to operate

4. Glass door
Sliding glass doors are the same height and width as double-width personnel doors, but they are made of durable glass with a vinyl frame. These doors come with safety locks to protect the interior, although they shouldn't be considered as secure or durable as the alternative doors mentioned above, since they are transparent.
Applicable environment: Office, storefront |shop or living space.
Features: Create better lighting for the interior in accordance with the environment, and the design is more fashionable

5. Combination door
For containers with larger space or special needs, it is usually also considered to design multiple channels
