Description

spring loaded pipe supports are key components in pipe support systems, providing cushioning and support against pipe displacement and load fluctuations, ensuring safe and stable operation of the system. A support spring assembly is a spring device mounted on a support with a pre-set initial load and deformation characteristics. It primarily supports the pipe, adapting to displacement and load fluctuations caused by factors such as temperature changes and pressure fluctuations through elastic deformation, ensuring stable and reliable support under various operating conditions.

PRODUCT PARAMETERS

Load range	Typically covers a range from 0.5 kN to 150 kN.
Displacement range	Standard travel range: 30 mm to 300 mm, customizable.
Operating temperature	Standard operating environment: -20℃ to +400℃; high temperatures require special materials.
Load deviation	Variable force type depends on spring stiffness; constant force type is typically ≤ 6%.
Spring component material	Spring steel (such as 60Si2MnA), stainless steel (such as 304, 316)
Structural component materials	Carbon steel (Q235B + coating) or stainless steel
Surface treatment	Carbon steel parts: sandblasting and rust removal followed by epoxy coating; Stainless steel parts: passivation treatment

STRUCTURAL COMPONENTS

● The spring is the core component, typically made of highly elastic materials such as spring steel. The spring type, specifications, and parameters are designed and selected based on the pipe's load and displacement requirements to provide the appropriate support force and elastic deformation range.

● The housing protects the spring from corrosion and damage from dust, moisture, corrosive substances, and other external factors. It also serves as a guide, limiting the spring's deformation direction and ensuring proper operation.

● The adjustment device, typically consisting of a screw and nut, adjusts the spring's initial compression, enabling precise adjustment of the initial load of the support spring assembly to suit the design requirements of different pipe systems. Connecting components, such as hangers, bolts, and nuts, are used to connect the bracket setting spring assembly to the pipe and bracket, ensuring that the assembly can be securely installed in the predetermined position and transferring the load of the pipe to the bracket.

APPLICATION AREAS

Energy and Power

Dense high-pressure steam and feedwater pipelines in power plant boiler rooms and turbine halls.

Petrochemical Industry

Intersecting process pipelines and flare pipelines above large plant areas.

District Heating

Heating main lines requiring vertical displacement control in thermal pipe corridors.

Industrial Facilities

Factories with numerous thermal displacement pipelines, such as paper mills and metallurgical workshops.

Ships and Offshore Platforms

Pipeline systems with compact spaces and sensitive structural dynamic responses.

DESIGN, INSTALLATION, AND MAINTENANCE HIGHLIGHTS

Design Highlights

Selection and arrangement must be based on complete pipeline stress analysis.

The hanger's own offset value (pre-compression or pre-tension) must be considered.

For long pipelines, it should be arranged in conjunction with guide supports and fixed supports.

Installation Highlights

Installation must be performed according to the design elevation and offset value.

All transportation locking devices must be released before pipeline system pressure testing and purging.

The rotating device of the constant force hanger should be in a vertical position.

Maintenance Highlights

Regular inspections should be conducted to observe whether the load displacement scale pointer is at the predetermined hot state position.

Check if the hanger rod is vertical and if there is any abnormal deformation or corrosion of the components.

Generally, it is a maintenance-free design, but in extreme environments or critical areas, professional inspections can be performed periodically.

FAQ

Q: How to ensure even load distribution when multiple spring hangers are used to support a long pipeline?

A: Precise pipeline stress analysis and professional selection are required. We will calculate and match the spring stiffness (variable force type) or design constant force points for each support point based on the different displacements and loads at each support point, avoiding overload or underload at individual points.

Q: If the hanger spring fails, will the pipeline suddenly fall? What safety design features are there?

A: Standard products have a built-in mechanical load safety device. When the spring breaks unexpectedly, the internal stopper will immediately lock, transferring the load to the rigid structure, preventing the pipeline from falling uncontrollably and providing safety protection for the system.

Q: Can the hanger rod be arbitrarily lengthened or shortened?

A: No. The hanger rod is a load-bearing component, and its length, diameter, and connection method are all designed and calculated. Any non-standard modifications must be confirmed by our engineers; otherwise, it will alter the system's rigidity, affect the hanger's performance, and pose safety risks.
