Product Q&A

Q:What is the density of the polyethylene pinch buoy?

The density of the foam-filled polyethylene pinch buoy should generally be about 35 kg/m3.

Q:How does the conveying efficiency compare to steel pipes?

Due to the extremely small friction coefficient of the smooth inner wall, the conveying efficiency is 20%-30% higher than that of steel pipes.

Q:Is the buoy flexible and durable?

Yes, it is light in weight, highly flexible, and elastic. It can be bent in water and squeezed without breaking, ensuring strong anti-wind and wave effects.

Q:What are the connection methods for the pipes?

Pipes are directly connected by bolts through flanges. The area where the concave and convex surface is within 30 degrees can be directly connected.

Q:Does the product support customization?

Yes, OEM and ODM services are available for this product.
