Magnetic pipeline pig!
There are many reasons for using this magnetic pig in the industry:
Easy-to-operate valves
It is convenient for operators to operate magnetic non-invasive pig annunciator detection equipment
Iron filings can be removed from the pipe
Generally, the pig that can operate the valve is in the small-diameter pig
Pigs used to operate valves are usually connected to small-diameter pigs. In the food industry, workers use it to open or close valves in the manufacturing process. They also often appear in the soft drink industry. Because it can open and close the valve. So it is very convenient to switch from one process to another.
And the corresponding magnetic pig annunciator detection equipment can detect the change of the magnetic field. And it can also be looking for changes in the magnetic field for pig operation. Magnets for this purpose can be glued to polyurethane cups on smaller-diameter pigs. Or we can directly install it on the main body of the pig.
The operator shall always consider the design, power, position and direction. They need to provide as high a Gauss / magnetic field as possible. This ensures that its magnetic field is most easily detected. The magnets used for this purpose are usually neodymium iron boron rare earth composite magnets. The characteristic of this kind of magnet is that it can be very small. But its magnetism is very strong. It is important to remember that the magnet is not installed in the main body of the carbon steel pig. Because the carbon steel pig body will cover the magnetic field generated by the magnet. This will minimize its power.
If they are installed on the main body, they shall be installed on the rear vane of the pig. Therefore, it protrudes from the back or is directly installed outside the pig body between the installation flanges.
