Spring and lever-cam linkage in a fabricated steel frame — the constant support pattern piping engineers have specified for decades. Supplied hanger-suspended or base-mounted, with load adjustment and travel scale; every unit is bench-tested and locked at the cold position before dispatch.
| Item | Range / Detail |
|---|---|
| Design practice | MSS SP-58; project specs on request |
| Mechanism | Lever-cam linkage (conventional pattern) |
| Load deviation | ≤6% per standard |
| Travel | 25–300 mm typical |
| Testing | Load-travel bench test per unit |
Simple rule: if the specification says "constant support, ≤6%", this series does the job economically. If the line is truly critical — main steam, reheat, near turbine nozzles — or the plant wants lateral damping in the same device, step up to our MA-Series (main & auxiliary spring) constant hangers with bench-verified ≤3% deviation. We quote both side by side on request.
The lever-type is the conventional linkage pattern used industry-wide: load deviation within the 6% that MSS SP-58 allows, at an economical price. The MA-Series uses a main and auxiliary spring mechanism that holds deviation within 3% and adds lateral damping — specified for critical lines. We build both and can quote them side by side.
Hot load, total vertical travel with direction, pipe size and temperature, and the arrangement — hanger-suspended or base-mounted. A hanger schedule or marked-up isometric is ideal; we size each unit and return a data sheet per tag.
Yes — each unit passes a load-travel bench test and ships locked at the cold position with hydrotest stops and transport locks fitted.
Primer finish as standard on the fabricated frame, with epoxy systems or hot-dip galvanizing to project specification for coastal and outdoor environments.
A bench test report and data sheet per unit, inspection reports, material certificates on request, and full export packing documents.
