Product Description:
Constant Load Spring Support is engineered to solve one of the most critical challenges in pipeline systems: maintaining stable load control when vertical displacement occurs. Unlike variable spring supports, where load changes proportionally with displacement, a constant spring support uses a precisely designed cam or lever mechanism to ensure that the load variation remains within a very narrow range, typically less than ±5%.
This performance is essential for pipelines operating under high temperature, high pressure, or complex stress conditions. Excessive load variation can introduce unwanted stress into the piping system, leading to nozzle overload, excessive deformation, or even long-term fatigue damage. By maintaining nearly constant support force, the constant spring support effectively protects pipelines and connected equipment such as pumps, compressors, and pressure vessels.
Manufactured using high-strength structural steel and high-quality alloy springs, the constant spring support offers excellent mechanical stability and durability. Each unit is designed based on actual operating load, hot and cold conditions, and required travel range. Precise calculation and strict quality control ensure accurate load performance throughout the entire operating cycle.
The structure is compact yet robust, allowing for easy installation and adjustment on site. Load indicators and travel scales are clearly marked, enabling engineers to visually verify correct positioning during installation and operation. This not only simplifies commissioning but also reduces inspection and maintenance time over the service life of the system.
With more than two decades of experience in pipe support design and manufacturing, our constant spring supports have been widely applied in petrochemical, LNG, chemical, and power generation projects. They comply with international engineering practices and can be customized to meet specific project standards, load ranges, and environmental conditions.
Main Structure
Industrial Application
A Constant Load Spring Support is a mechanical pipe support device designed to maintain an almost constant supporting force throughout the vertical movement of a pipeline. It is widely used in piping systems where thermal expansion or contraction causes significant displacement, such as in petrochemical plants, power stations, refineries, and high-temperature process units.
Advantage
Symmetrical design ensures direct flow of forces through axis of symmetry.
Favourable power-weight ratios for reduced installation loads.
Arranged by load groups and travel ranges to simplify selection (modular system).
Consistent functional behaviour due to high-quality corrosion protection and maintenance-free, chemically nickel-plated finishes.
Readily adaptable to the installation situation due to suitable designs and standardised accessories.
Double load-tube guiding of constant supports for transmission of side loads.
Secure connection of load chains due to load- and connection-compatible modular components.
fAQ
1. When should a constant spring support be used instead of a variable spring support?
A constant spring support is recommended when pipeline vertical movement is large and load variation must be strictly controlled to avoid excessive stress.
2. What is the typical load variation of a constant spring support?
The load variation is usually controlled within ±5%, ensuring stable support force throughout the full travel range.
3. Can constant spring supports be customized for specific projects?
Yes. Load, travel, connection type, and standards can all be customized based on project requirements.
