Building services is a volume market where the engineering is well understood and the value is in getting the right product to site quickly. Vibration isolation and riser expansion are the two duties.
Applications and the products that suit them
| Application | Product |
|---|---|
| Chiller and pump connections | Braided corrugated hose in 304L, vibration isolation |
| Chilled water riser expansion | Axial expansion joint or Lateral / universal joint |
| Hot water and heating circuits | Braided corrugated hose in 304L |
| Cooling tower connections | Braided corrugated hose in 316L — treated water carries chlorides |
| AHU and fan coil connections | Braided corrugated hose small bore, braided |
| Boiler and calorifier connections | Braided corrugated hose in 304L |
| Generator exhaust connections | Interlock hose in 321 |
Specification notes for this sector
- 304L is normally adequate; 316L on cooling tower and treated-water circuits
- Vibration isolation assemblies must be installed slack, never taut
- Riser expansion needs guides as well as a joint
What to send with an enquiry
Bore, medium, pressure, temperature, movement and both end connections. The reasoning for each is on how to specify an assembly.
