Pipe supports
From the variable spring support to the −196 °C cryogenic support: we calculate, manufacture and test every support at our Madrid plant, to your specification and with full traceability.
Exploded view
Scroll through the exploded view. Every component answers to a calculation and a test: that is how we guarantee the load carried by your piping is exactly the one in the project.
Loading sequence…
Carbon steel, SA 2½ shot-blasted, paint system to specification
Individually calibrated on the bench: spring rate verified against the drawing
With a visible travel scale for in-service inspection
Threaded components with 3.1 material certificates
Precompressed and locked at the project's installation load

The range
Every family follows the PIHASA 147A catalogue and can be built to client standards. Download the datasheet for each one, or ask our engineering team to help you select it.
Series A–H · individually calibrated
They absorb the vertical displacement of the pipe while keeping the load within the admissible deviation. Series A–H with different travels and load ranges, calibrated and locked at the factory.
Deviation ≤ 6 % over the full travel
A virtually constant load across the entire travel: the solution when displacement is large and the admissible load deviation is small. Available in base-mounted or hanging configurations.
Components per catalogue 147A
Rods, turnbuckles, clamps, lugs and hanging structures for lines without significant vertical displacement. The foundation of any well-engineered support arrangement.
Designed to stress loads
Stops, guides and anchors that control the line's degrees of freedom: they direct thermal expansion exactly where the flexibility analysis needs it.
Fig. 2136 quadruple shoe and family
Sliding and resting supports for pipe racks and horizontal lines. With or without slide plate, insulated or in direct contact.
Snubbers · seismic applications
They allow slow thermal movement and lock against dynamic events: water hammer, seismic activity, safety valve discharge. Essential protection in process and nuclear plants.
PTFE µ ≤ 0.1 · self-lubricating
They reduce friction at sliding supports down to design values (µ ≤ 0.1), lowering loads on structures and equipment nozzles.
Up to +600 °C
Pre-insulated supports for hot lines: they break the thermal bridge while maintaining load capacity, without degrading the line's insulation.
Down to −196 °C · PUF / resins
For LNG and liquefied gases down to −196 °C: high-density PUF cores, laminated wood or resins, calculated against both load and thermal bridging.
Built to client standards
When the standard range isn't enough, we build to your drawings or client standards: high-tonnage supports, singular geometries, special materials. Engineering and workshop under one roof.
Engineering
We integrate our work with your stress office: starting from your isometrics and loads, we propose the optimal selection for every support and deliver complete documentation —drawings, calculations, material certificates and the quality dossier—.
