DN150 blue aluminum alloy compressed air pipe system in FSTpipe China brand

why use a clamp connection? you will see our connection for 50-200mm is a clamp connection. actually, FSTpipe was using put in fit connection in the past, while some feedback are given from engineers, they said it is not easy to install at a high height, and if anyone did not install it properly, there will be a risk of take-off after compressed. It is risky, we test and test, check and check. finally, we changed, from 50mm to 200mm. After this change, our engineers and customers never complain again about this. All love this design.
