3.Technical Performance of the product:

 

 

 

4.dimension:

 

 

 

5. Characteristics:

 

1) reasonable structure,good elasticity,large range of compensation pipeline and little counterforce to the brackets of pipeline.

 

2) shock absorption and noise decrese, heat and dust insulation

 

3) the displacement can be deflected to prevent damage caused by subsidence of connected brackets and equipment base.

 

4) it is convenience to installation and maintenance

 

5) good resistance to milling, heat, aging and corrosion

 

6) little resistance and little weight, each performance is better than the compensation device of other materials

 

7)the temperature range of media is wide: -40~-300°C
