Horizontal Constant Spring Support

In many industrial sites, limited space above pipelines makes it impossible to install vertical constant spring supports. Meanwhile, some pipelines require support from the side or below, and traditional support methods struggle to meet constant force requirements under large displacements. The Horizontal Constant Spring Support is a dedicated product designed specifically to solve these problems. It is installed horizontally below or beside pipelines, providing stable supporting force throughout the entire working stroke with a load variation rate controlled within 5%.

Working Principle and Structural Features

The horizontal constant spring support operates based on the moment balance principle. When the pipeline undergoes vertical displacement, the elastic force of the spring is converted into a constant output force through a precision linkage and cam mechanism. Unlike vertical supports, its spring assembly is arranged horizontally, resulting in a lower center of gravity and more stable operation, making it particularly suitable for large-load and large-displacement pipeline systems.

The standard Horizontal Constant Spring Support adopts an integrated welded frame structure, with main components including:

▶  Horizontally arranged cylindrical helical spring assembly

▶  High-precision moment balance linkage system

▶  Side-mounted load adjustment mechanism

▶  Dual-stroke limit device

▶  Visual displacement indicator

▶  Bottom mounting base

Frequently Asked Questions (FAQ)

Q: Can horizontal constant spring supports be installed on steel structures?

A: Yes. We provide multiple mounting base forms to adapt to concrete foundations, steel structure beams and equipment platforms. For large-load models, we will provide foundation design recommendations to ensure installation strength meets requirements.

Q: Can your Horizontal Constant Spring Support be used in low-temperature environments?

A: Yes. We offer special low-temperature models that adopt 304 or 316L stainless steel materials and have passed low-temperature impact tests. They can operate normally at temperatures as low as -196℃ and are suitable for cryogenic pipeline systems such as LNG and ethylene.

Q: What is the delivery time for your products?

A: The delivery time for standard models is 30-45 days, and for customized models it is 45-60 days depending on complexity. For urgent orders, we can arrange expedited production with the shortest delivery time of 20 days.
