Forged Storz couplings are superior to cast ones, as they exhibit higher strength, no air inclusions, and greater reliability. The Fire-Bird Ltd advises against the use of cast couplings due to the risk of brittle fracture and low strength values, and recommends exclusively forged coupling parts for safety reasons.
Differences in detail
- Strength:Forged parts are significantly stronger than cast parts.
- Air inclusions:The casting process can lead to air inclusions, which are not present in forged parts.
- Safety:The low strength values of cast couplings pose the risk of dangerous brittle fractures, which is why forged parts are considered safer.
Conclusion
For safety reasons and due to the significantly better mechanical properties, forged Storz coupling parts should always be preferred.
