Product Details
Constant Spring Hanger | Constant Force Spring Pipe Hanger
Constant spring hanger, constant force pipe hanger, spring support hanger, industrial constant spring support, pipeline spring hanger
Product Overview
Constant Spring Hanger is a specialized load-bearing pipeline suspension device designed to solve vertical displacement problems of high-temperature and high-pressure piping systems. Different from rigid pipe brackets and fixed supports, this constant force spring hanger provides nearly unchanged supporting load during pipeline thermal expansion, cold contraction and vertical displacement. It effectively eliminates pipeline stress concentration, prevents pipeline deformation, joint leakage and equipment damage caused by load fluctuation. Manufactured strictly in accordance with international industrial standards, our constant spring hangers feature stable constant force performance, high structural precision and long service life. They are widely applied in thermal power plants, petrochemical industry, heating engineering, nuclear power and large industrial piping systems, serving as indispensable safety supporting components for flexible displacement pipelines.
What Is a Constant Spring Hanger?
A constant spring hanger is an engineered pipe support that uses a helical coil spring combined with a geometrically shaped cam (or bell crank lever mechanism) to offset the spring's natural load variation. As the pipe moves vertically due to thermal expansion or contraction and the spring deflects, the cam rotates about a main pivot point, changing its mechanical advantage to compensate for the spring's variable resistance.The result is a nearly constant output force across the entire travel range
Why Constant Spring Hangers Are Required
Constant spring hangers are specified in pipe stress analysis whenever.
The vertical thermal movement at a support point exceeds the capacity of a variable spring hanger
The load variation of a variable spring would exceed 25% (the MSS SP-58 limit)
The support is located near critical equipment nozzles—turbines, compressors, reactors—where load consistency is required
The pipe operates at high temperature (above 350°C / 660°F) and undergoes large vertical displacement
Thermal displacement exceeds approximately 50 mm
The piping system is critical to plant operation
Applications
• Power Generation Plants – Main steam lines, high-energy piping, boiler feed water systems.
• Petrochemical & Refineries – Reactors, reformers, heater outlet lines, high-temperature process piping
