U-shaped sealing strip
U-shaped sealing strip is a special shape of sealing material, usually made of rubber, silicone or fluororubber. Its cross section is "U" shaped, with good sealing performance and elasticity, and can be used to fill or seal gaps of different shapes or sizes to prevent liquid or gas leakage. U-shaped sealing strip is suitable for various mechanical equipment, automobiles, ships and other fields.
specification
Material: Common materials include nitrile rubber (NBR) fluororubber (FKM) silicone (VMQ) etc.
Size: Usually specified in terms of width height and thickness but can be customized based on specific needs.
Cross-sectional shape: "U" shape
Color: usually black gray white etc. can also be customized according to customer needs.
The quality control of U-shaped sealing strips usually includes raw material inspection, production process control, finished product inspection and performance testing. Through strict quality control, ensure that the sealing strips have good sealing performance, durability and stability.
U-shaped sealing strips are widely used in the following fields:
Mechanical equipment: used to fill or seal the joints of pipes, bearings, valves and other equipment to prevent liquid or gas leakage.
Automotive industry: used for sealing of automobile engines, transmission systems and other parts to ensure the normal operation of various parts of the car.
Shipbuilding industry: used for sealing of ship equipment to ensure the safe navigation of ships.
Clean the installation surface: Make sure the installation surface is clean, dry, free of oil and dust.
Apply lubricant: Before installing the U-shaped sealing strip, you can apply lubricant appropriately to reduce friction and facilitate installation.
Appropriate heating: For U-shaped sealing strips with higher hardness, you can heat them appropriately before installation to increase their softness and facilitate installation.
Storage: U-shaped sealing strips should be stored in a cool, dry and ventilated place, avoiding direct sunlight and high temperature environment.
Avoid contact with chemicals: Avoid long-term contact of U-shaped sealing strips with oils, solvents and other chemicals to avoid affecting their performance.
Packaging: Usually plastic bags, cartons or boxes are used to protect the sealing strips from contamination or damage.
Transportation: Transportation by land, sea or air to ensure that the product is not damaged during transportation.
1. How to choose the right material for U-shaped sealing strips?
- The choice of material should be determined according to the specific working environment and requirements. For example, NBR is suitable for general industrial occasions, FKM is suitable for high temperature and chemically corrosive environments, and silicone is suitable for high temperature and food-grade applications.
2. What is the temperature resistance range of U-shaped sealing strips?
- The temperature resistance range of U-shaped sealing strips of different materials is slightly different, usually between -40°C and +200°C.
3. How to check the sealing effect after the U-shaped sealing strip is installed?
- After installation, the sealing effect can be checked by applying some water or oil to the seal and observing whether there is leakage.
4. Can the U-shaped sealing strip be reused?
- Generally, the U-shaped sealing strip can be reused, but when removing and reinstalling it, you should carefully check whether there is any damage on its surface to ensure the sealing effect.
