EXPANSION JOINT

The definition of expansion joint is one of several types of connections that are often used in piping installations. Its role is very important, especially to reduce the vibration caused by the pump.

Function Of Expansion Joint

Expansion joints are used to prevent vibration and pressure. So what are the other functions and advantages of this tool?

1. Reducing the pressure or contraction arising from the condition of the passing liquid or gas

2. Reducing vibrations that occur in pipe joints through which liquids or gases pass

3. Reducing the occurrence of noise

4. Reducing the occurrence of fractures or leaks due to shifting between pipes

5. Easy to install or apply.

Material Composition Of Expansion Joint

To optimal performance, one thing that is no less important is the selection of the right material, as well as this tool. Materials or materials used to manufacture Expansion Joints are usually in the form of:

1. Iron (Iron): iron is a good heat conductor. Therefore, it is not surprising that iron is often used as a manufacturing material that is commonly used to make this connection. Starting from cast iron to high straight metal alloy cast iron, many are used for large valve pipes. However, one of the drawbacks of cast iron is that it cannot withstand temperatures over 4500 F.

2. Steel (Steel): For high-strength pipe materials, steel is the right material. The reason is, steel raw materials can perfectly flow high pressure and temperature.

3. Stainless Steel: Unlike ordinary steel, stainless steel is known as the best anti-corrosive or anti-rust material so that it is more durable. Stainless steel is also the best conductor for low temperatures.

4. Brass (Brass): Typically, brass joints are used for temperatures below 4500 F and pressures less than 250 psi

5. Bronze (Bronze): If the temperature is greater than 5500 F, then this material is very suitable for use. Apart from being intended for high temperatures, bronze is also excellent for withstanding pressures greater than 330 psi

6. Fiber: If you often see expansion joints that are often installed to complement architectural needs, usually the type of connection that is installed for architectural needs is made of fiber.

7. Rubber (Rubber): Used as a connection with elasticity to reduce very large vibrations and for low pressure
