Degaussing steel pipe is a steel pipe that does not have magnetism itself. Because its surface is generally galvanized, it is also called degaussing hot-dip galvanized steel pipe. The appearance of degaussing steel pipe is not much different from that of ordinary hot-dip galvanized steel pipe, but there is a big difference in essence. Galvanized degaussing steel pipe is used as a material for pre-embedded threading in subways, high-speed rail stations, civil air defense construction, and high-voltage substations. It has a wide range of applications. Degaussing steel pipes can effectively prevent signal loss caused by wires and cables passing through pipes.
Degaussing steel pipe can be processed according to the needs of the project and suitable for construction. For example, add welded hydrofoil rings to the straight pipe section, usually the thickness of the waterstop ring is 5-10mm, and it can also be made into bent pipes, which is suitable for use in irregular geographical environments such as hills, river beds, and mountains. If the surface is galvanized, it can increase the corrosion resistance of the steel pipe and prolong the service life. Galvanized degaussing pipes have a wide range of uses, except for pipelines for general low-pressure fluids such as water, gas, and oil. It is also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, oil heaters, condensing coolers, coal distillation oil exchangers for chemical coking equipment, trestle pipe piles, and support pipes for mine tunnels.
Degaussing process of degaussing steel pipe:
1. Simple degaussing: use the "alternating magnetic field" to wrap a coil around the outside of the steel pipe, let the coil pass through the alternating current, and slowly reduce the alternating current (the slower the better), until it is reduced to zero. Degaussing is complete. Degaussing result: The physical properties of the steel pipe will not be changed, but once it encounters an external magnetic field again, the steel pipe will still be magnetized.
2. Complex degaussing: Through the heat treatment process, it can be degaussed more thoroughly. However, after degaussing, the hardness and rigidity of the steel pipe will change. When an external magnetic field is encountered in the future, after the external magnetic field disappears, the steel pipe will basically have no residual magnetism. About the process of degaussing heat treatment: heating to a certain temperature without oxygen, and then slowly cooling down to room temperature in 72 hours.
Degaussing steel pipe characteristics:
1. High pressure bearing, good mechanical properties of steel pipe,
2. Strong chemical corrosion resistance
3. Strong coating adhesion
4. No nodules, no scaling, small fluid resistance
5. Flame retardant, antistatic
6. Various connection methods, convenient for construction
7. No electrical corrosion, low magnetic
8. Wide range of application
