Yangzhou Tianshun Pipeline Technology Co., Ltd., founded in 2012, has focused on the manufacturing of pipeline support products for 14 years, with products serving more than 40 countries around the world. Standing Constant Spring Support is a product specially designed for working conditions where there is no lifting space above the pipeline and bottom support is required. It is placed on steel beams, concrete foundations or support platforms through the base, providing constant upward supporting force for pipelines, and perfectly solving the pipeline displacement compensation problem in space-constrained scenarios.
In practical engineering, many pipelines cannot adopt top suspension solutions and must use bottom support:
▶ Bottom layer pipelines in pipe galleries: No steel structure beams available for suspension above the lowest layer pipelines
▶ Pipelines on top of equipment: Pipelines directly arranged above equipment, no lifting points above
▶ Pipelines in concrete trenches: Pipelines in pipe trenches with narrow top space
▶ Large-diameter pipelines: Pipelines above DN800, excessively long suspension rods are prone to instability
▶ Vibration-sensitive pipelines: Pump inlet and outlet pipelines, bottom support has better stability than suspension
▶ Retrofit projects: Existing steel structures cannot add new lifting points, only support from foundation is available
In these scenarios, Standing Constant Spring Support is the only feasible constant force support solution.

Standing Constant Spring Support adopts a vertical box structure, mainly composed of the following parts:
Base plate: Wide bottom plate to disperse load and ensure stability
Spring box: Built-in constant force spring mechanism, vertically arranged
Support top plate: Connected with pipeline pipe support, height can be fine-tuned
Displacement indicator: Visualized on the side for easy observation
Locking device: Locks spring during transportation and installation
Vertical spring arrangement, overall height 40% lower than suspension type of the same specification
Suitable for space with limited floor height such as pipe trenches and equipment rooms
Shorter specifications customizable for special working conditions
Base area 3 times larger than suspension type, low center of gravity
Not easy to overturn under pipeline horizontal thrust
No suspension rod swinging problem under vibration working conditions
Ground installation, no high-altitude operation required
Directly place on the foundation, fix after leveling
Adjustment bolt on the top, operable while standing on the ground
No need to dismantle pipelines for maintenance and replacement, directly pull out spring assembly
Especially suitable for working conditions with upward thermal displacement of pipelines
Also adaptable to downward displacement, just install reversely
Lateral displacement does not affect constant force performance

Application Scenario |
Working Condition Characteristics |
Why Choose Standing Type |
|
Bottom layer pipelines in pipe galleries |
Lowest layer pipelines, no steel beams above |
Can only support upward from pipe gallery floor |
|
Pump inlet and outlet pipelines |
Large vibration, sensitive to thrust |
Stable bottom support, reduces vibration transmission |
|
Pipelines on top of heat exchangers |
Arranged above equipment shell |
No lifting points on equipment top, direct support |
|
Pipelines in pipe trenches |
Concrete pipe trenches, narrow space |
Insufficient top space, suspension impossible |
|
Large-diameter steam pipelines |
Above DN800, heavy weight |
Excessively long suspension rod prone to instability |
|
Retrofit project pipelines |
Existing steel structures cannot be drilled |
Utilize existing concrete foundation for support |
|
Compressor pipelines |
Vibration caused by pulsating flow |
Rigid support + constant force compensation, good vibration damping effect |
1. Check whether product model is consistent with design drawings
2. Check whether locking device is intact and whether there is looseness during transportation
3. Check base flatness, correction required if deformation exceeds 2mm
1.Foundation leveling: Levelness error of support foundation surface ≤2mm/m
2.Positioning and fixing: Place Standing Constant Spring Support in position, weld or bolt fix the base to the foundation
3.Pipeline connection: Connect pipeline pipe support with bracket top plate, reserve cold-state displacement
4.Load setting: Adjust top bolt according to design requirements, align indicator plate with cold-state position
5.Unlock: Remove transportation locking bolts after installation
6.Inspection and confirmation: Confirm indicator can move freely without jamming
