Hot-dip galvanised steel finned tubes for a large greenhouse heating installation, where humidity and condensate rule out bare steel.
Requirement
The greenhouse operator needed a durable heating pipe that would resist condensation and fertiliser-laden humidity for at least fifteen years, at a cost that made sense across several hectares of growing area.
Solution
| Item | Specification |
|---|---|
| Base tube | Carbon steel, 33.7 mm OD |
| Fin | Carbon steel, 12 mm height, 4 mm pitch |
| Finish | Hot-dip galvanised after finning |
| Quantity | 4,800 m |
Result
The galvanised finish gave the corrosion protection the aluminium fins could not provide in a wet greenhouse, and the wider pitch tolerated the dust and debris typical of a working glasshouse.
