A plastic expansion plug is a plastic fastener which consists of a plastic tube and a screw, it has the characteristics of good elasticity, high tensile strength, impact resistance, no cracking, strong hardness, no rust, and high elasticity, they need to be fastened with screws.
Material: Plastic parts are crafted from HDPE (typically made by injection molding high-density polyethylene).
Screw: Countersunk self-tapping screws, round head self-tapping screws, large flat head self-tapping screws, hexagonal external and internal self-tapping screws, double-ended screws, etc.
Application industries of plastic wall plugs:
Also called expandable plastic plugs, they are vital components used in a wide range of industries and fields. These flexible expansion plugs play a critical role in accommodating thermal expansion, vibration, movement, and misalignment in piping systems. Let's explore the diverse applications of expanding plugs across different sectors.
- Oil and Gas Industry
In the oil and gas industry, wall plugs are extensively employed for pipeline systems. They allow for thermal expansion and contraction caused by temperature fluctuations in the pipelines. Expansion plugs ensure the integrity and safety of the system while minimizing the risk of leakage or structural damage.
- Home Decoration
Wall plugs can be used in hollow wall, ceiling, splint, sheet for fixing the wall.
- Power Generation
Wall Plugs can be used in thermal power plants, nuclear facilities, and renewable energy installations heavily rely on expansion joints to absorb thermal movements and vibrations. They help compensate for the expansion and contraction of pipelines, ducts, and chimneys, ensuring efficient operation and reducing the possibility of equipment failure.
- Chemical Processing
Wall plugs are found in various chemical processing units, including refineries, petrochemical plants, and pharmaceutical facilities. These joints accommodate the thermal stresses and vibrations generated by chemical reactions and processes, thus safeguarding the integrity of the piping systems and equipment.
- Automotive Industry
Plastic expandable plugs are applied in automotive exhaust systems, which experience high temperatures and continuous vibrations. These joints help absorb the thermal expansion and vibrations, reducing stress on the system and improving overall performance.
