The constant effort spring support is an industrial-grade component integrating precision mechanics and reliable structural design. Its robust steel shell houses a spring assembly and constant-force mechanism made of spring steel. When pipelines expand upward due to heat, the mechanism activates to maintain constant force through a lever system, preventing sagging. During cooling and contraction, the mechanism reverses direction to sustain consistent suspension force, eliminating tensile stress on pipelines. With dustproof and corrosion-resistant capabilities, this device ensures long-term stable operation in complex environments like power plants and chemical facilities, serving as a critical connector for flexible pipeline design and rigid safety.
