Installation Requirements For Pipe Expansion Joints In Heat Pipes

Jan. 28, 2019

Pipe Dismantling Joints are widely used in heat pipes and are also very stable on many high temperature pipes. Loosen the platen bolts before installation, lengthen the pipe expansion joints to the installation length, and then tighten the bolts diagonally. Do not bias.

Pipe expansion joints are widely used in heat pipes and are also very stable on many high temperature pipes, because the compensation pipes are displaced due to thermal expansion and contraction. So, do you know the installation requirements and design requirements for the thermal Metal Expansion Joint ?

1. Loosen the pressure plate bolt before installation, lengthen the pipe expansion joint to the installation length, and then tighten the bolt diagonally. Do not bias it.

2. It should be installed between the two fixed brackets on the straight section of the pipeline. In order to ensure the normal expansion and contraction of the retractor and prevent pull-out, there should be no guide brackets and gears.

3. The heat pipe expansion joint is made of high quality steel, and the use temperature is 150 °C-300 °C. The pressure of the heat pipe retractor is 1.0 MPa and 1.6 MPa.

4. Before installing the heat pipe retractor, loosen the platen bolts, pull the thermo-vibrator to the installation length, and then tighten the platen bolts diagonally. Do not pressurize and then connect the products at both ends.

5. The heat pipe retractor should be installed between the two fixed brackets on the straight line of the pipe to prevent pulling.
