Metal sealing ring is a kind of the sealing materials. It can be used in FRP pipes, cable protection pipes, coal mine drainage pipes, etc.
This type of sealing ring is also used in a wide range of industries, such as petroleum , Metallurgy, papermaking, etc. When using the sealing ring, it is necessary to pay attention not to use it for an extended period of time, or to install it forcibly. The following is a detailed introduction for everyone.

1. The use of metal sealing ring
1. It can be used as seal products in FRP pipes, FRP sand pipes, FRP top pipes, cable protection pipes, flue gas desulfurization pipes, coal mine drainage pipes, and power plant desulfurization and dust removal pipes.
2. The sealing in municipal water supply and drainage pipelines.
3. All kinds of process pipeline sealing, such as petroleum, chemical industry, metallurgy, papermaking, sewage, sea water, food brewing and beverage processing, and medicine.
4. The water pipeline in the sewage collection and transportation pipeline sealing.
5. The sealing of drinking water transportation trunk pipelines and water distribution pipes.
6. The sealing in the oil field water injection pipe.

2. Safety precautions for metal sealing ring
1. Prevent overdue use. The service life of rubber seals for dynamic seals is generally 3000～5000h, and new seal rings should be replaced in time.
2. Avoid using old sealing rings. When using a new sealing ring, check its surface carefully to ensure that there are no defects such as small holes, protrusions, cracks and grooves, and have sufficient elasticity before using it.
3. When replacing the sealing ring, check the groove of the sealing ring strictly, remove the dirt, and polish the bottom of the groove.
4. Don't install the wrong direction and damage the lips. If there are scars above 50μm on the lips, it may cause obvious oil leakage.
5. Prevent forced installation. Do not use a hammer to knock in, but use a special tool to press the sealing ring into the seat hole first, and then use a simple cylinder to protect the lip through the spline. Before installation, apply some lubricating oil to the lips to facilitate installation and prevent burns during initial operation. Cleaning should be carefully.
6. The size of the replacement seal should be consistent. It is necessary to strictly follow the requirements of the instructions, and select the same size of the sealing ring, otherwise the tightness and other requirements cannot be guaranteed.
7. When installing, you should strictly clean all parts of the opened hydraulic system first, and it is best to use special tools to prevent fingers from being scratched by sharp metal edges.
8. In order to prevent damage and cause oil leakage, it must be operated in accordance with the regulations, and at the same time, the machine cannot be overloaded for a long time or run in a relatively harsh environment.
