What is a compact constant spring support?
A compact constant spring support packages the load-supporting spring and compensation mechanism within a restrained installation envelope. The product is specified by its load and travel schedule, together with its mounting and connection arrangement.
Key dimensions and installation fit
A constant effort unit must be selected by design load, total movement, mounting type and available space together. Horizontal suspension and compact floor support are different arrangements. Obtain the selected unit’s load/travel curve, setting schedule and acceptance test requirements; another maker’s catalogue range is not a JINYI capacity. Compare related configurations: horizontal constant spring hanger, base mounted spring support.
How to specify the compact constant spring support
Define the available space as well as operating load and displacement. Check connection alignment, access to the travel indicator and adjustment points, and the required cold or installed setting. A smaller housing is not proof of a lower or higher capacity.
Select a constant support from the combined design load, total travel, direction of movement and mounting arrangement. State cold and hot settings and allow travel reserve. Housing dimensions and rod or base connections follow the selected model; they cannot be inferred from the product photograph.

Sizes and dimensional requirements
Use the named standard for standardized interfaces and the controlled drawing for custom dimensions. Confirm units, diameter datums, minimum finished thickness and any mating-component requirements. A catalogue dimension is not a universal tolerance, capacity or pressure rating.
Dimensions and tolerance schedule
| Individually toleranced features | Limits and datum system on the approved drawing |
|---|---|
| General tolerances | Standard, edition and class apply only when specified |
| Constant-effort acceptance | Agreed load variation over the complete working travel |

Materials, inspection and documentation
Request a setting schedule and a load-versus-travel test record for the ordered support. Identify the cold/hot positions and travel stops. Keep installation locking devices in the specified position until the piping commissioning sequence allows release. Check the movement indicator and complete load path after installation.
State the exact material designation and supplied condition, the controlled drawing revision and the required inspection reports before ordering. Separate material certification from dimensional checks and functional or pressure testing. Agree the acceptance limits for the ordered component and identify any additional witnessing, marking or packing requirements. Use the pipe support and casing manufacturing guidance to confirm fabrication and inspection requirements.
Installation and handling guidance
Keep the support identification matched to the piping support tag. Inspect the installed position, indicator and locks before commissioning. Retain clearance for the full planned movement and preserve access needed for inspection after insulation or nearby equipment is installed.
Where the compact constant spring support is used
- Thermally moving pipework. Supporting lines where a controlled supporting force is required over travel.
- Equipment connections. Limiting changing reactions through the support design.
- Power and process plants. Project-selected assemblies with documented cold and hot settings.
How to order a compact constant spring support
Send the required configuration, material, quantity, destination and controlled drawing to JINYI. Identify changed dimensions, mating components, operating conditions and inspection scope. For a repeat order, include the previous approved revision and state any changes. The final quotation defines the supplied geometry, documentation, price and delivery terms.

Compact Constant Spring Support selection and quotation checklist
The compact constant-load arrangement is selected by load, movement and envelope. Check the available height and connection position rather than treating it as a variable spring support. Use the photographed product form to identify the arrangement, then use the controlled drawing to define what will be supplied. Similar-looking components can have different end details, load paths or maintenance requirements.
Compact Constant Spring Support dimensions and tolerances
The first comparison for this compact constant spring support is installation height and working travel. Mark the dimensions that control mating, alignment and installation space on the enquiry drawing. Give units for every value and identify the datum from which it is measured. If a dimension is critical, specify its individual tolerance and measurement method rather than relying on a general tolerance note.
A constant effort unit must be selected by design load, total movement, mounting type and available space together. Horizontal suspension and compact floor support are different arrangements. Obtain the selected unit’s load/travel curve, setting schedule and acceptance test requirements; another maker’s catalogue range is not a JINYI capacity. Review the selection schedule together with the final drawing and inspection requirements.
Prepare the material and interface information
For a compact constant spring support enquiry, identify the required material designation and supplied condition. Describe the mating components, attachment method and environment. Include the operating temperature and any relevant pressure, movement or structural load. These inputs should describe the actual installation, including changes between normal operation, start-up and maintenance where applicable.
Specify coatings, surface finish and marking separately from the base material. If traceability is needed, identify the record required and how it must correspond to the delivered component. Agree whether inspection covers dimensions, material documentation, welds or functional testing; these are different checks with different acceptance criteria.
Custom compact constant spring support quotation
Attach the latest drawing revision, required quantity and delivery destination when contacting JINYI. Highlight departures from the illustrated arrangement, including changed dimensions, connections, finish and packing. For repeat orders, reference the approved configuration and list changes explicitly so an earlier drawing is not assumed to remain current.
Compare quotations using the same geometry, grade, supplied condition, unit of supply and inspection scope. A piece, a segment and a complete assembly can represent different quantities. Confirm quantity discounts and delivery terms with the final quotation.
Compare related component arrangements

Questions to resolve before ordering
Which dimensions need checking first?
Start with installation height and working travel and the mating or mounting detail. Check nominal designations against measured dimensions, then review the installation envelope. Photographs help identify the form; the drawing provides the dimensional basis for acceptance.
What should the quotation include?
A compact constant spring support quotation should identify the configuration, drawing revision, material, quantity, price basis and agreed inspection records. Keep these details together with the approved order so receiving inspection can compare the delivered product with the specified component.
