Sway Strut Hydraulic Snubber
Sway Strut : This is a device that restrains movement in a specific direction but allows movement in other directions it is designed to accommodate angular piping movements thanks to its integrated spherical bearing.

Variable Spring Hanger Constant Spring Hanger
- Variable Spring Hanger : It features a design that compresses a spring inside a cylinder and is called as a variable spring hanger because the spring's reaction force changes according to the movement of pipe position the pipe moves to upward or downward due to thermal expension. It is used at a place having small amount of thermal displacement and has advantages of simple structure and low price.
- Constant Spring Hanger : This is same as the variable spring hanger, but has a feature that the reaction size of spring is constant even though the pipe moves up and down via a specially designed mechanism.. Explaining briefly, it is called as a constant spring hanger because when the same weighted materials are place on both sides of a scale, the balance is maintained. The constant spring hanger is used at main lines where there is minimal stress change.
