Inflatable Pipe Floats Buoys

Recently, we designed one kind new arc-shaped pipe float buoys. This type pipe float buoys can connect with the pipe closer to get more buoyancy in the shallow water condition. We can make pipe float buoys according to the different diameter pipe. The buoyancy is from 1ton to 10ton each unit. Arch-shaped pipe floater has three lifting webbing sling. So pipe laying float can be strapped to the pipeline to reduce [...]
