1.Long service life
Longer life reduces maintenance effort and costs.
| Piping Type | SUS pipe | SGP tube | STPG tube |
|---|---|---|---|
| Service life | 40 years | 30 years | 30 years |
2. Low pressure loss allows for reduction in piping diameter
Even if the outer diameter is the same, the inner diameter of the SUS pipe is larger due to the difference in wall thickness.
| Piping Type | SUS pipe (100Su) | STPG pipe (100A) |
|---|---|---|
| 400L/min | 0.55m | 0.94m |
3. Reduction of load on the main structure
By reducing the load on the main structure, the burden on the building can also be reduced.
| Piping Type | SUS pipe (100Su) | SGP pipe (100A) | STPG pipe (100A) |
|---|---|---|---|
| specific gravity | 7.93 | 7.9 | 7.9 |
| Piping weight | 5.59kg/m | 12.2kg/ｍ | 16.0kg/m |
| Joint Weight | 1.49kg/m | 3.13kg/m | 4.12kg/m |
| Equipment piping (4m) 1 joint | 23.85kg | 51.93kg | 68.12kg |
| Equipment load (4m) | 23.85kg (pipe weight) + 38.20kg (water weight) = 62.05kg/4m (equipment weight) | 51.93kg (pipe weight) + 34.82kg (water weight)= 86.75kg/4m (equipment weight) | 68.12kg (pipe weight) + 32.86kg (water weight)= 100.98kg/4m (equipment weight) |
4. Lightweight processed pipes for efficient construction
Piping weight comparison (example)
| When SGP pipe is set to 100 | Weight reduction tips | |
|---|---|---|
| Water-discharging sprinkler equipment at a shopping mall |  | Caliber 150A→125Su |
| Water spray equipment at a certain factory |  | Caliber 200A→150Su |
| A certain complex facility ndoor fire hydrant and fire fighting hydrant |  | Uses both ndoor fire hydrant and fire fighting hydrant |
5. Environmentally friendly with significant reduction in carbon dioxide emissions
Carbon dioxide emissions from the production and processing of piping can be reduced by 21% to 45%.
| Piping Type | SUS pipe (100Su) | STPG pipe (100A) |
|---|---|---|
| carbon dioxide emissions | 15.00 | 23.81 |
