Product Q&A
Q:What is the density of the polyethylene pinch buoy?
A:
The density of the foam-filled polyethylene pinch buoy should generally be about 35 kg/m3.
Q:What are the tensile strength requirements?
A:
The tensile strength should be about 0.2MPA, ensuring the material is slightly elastic, not sticky or brittle.
Q:How are the pipes connected?
A:
The area where the concave and convex surface is within 30 degrees can be directly connected. Pipes are connected by bolts through flanges.
Q:What is the efficiency improvement compared to steel pipes?
A:
The inner wall is smooth with an extremely small friction coefficient, making the conveying efficiency 20%-30% higher than that of steel pipes.
Q:Is the buoy resistant to UV and corrosion?
A:
Yes, the pipe material has strong corrosion-resistance, anti-ultraviolet, and anti-aging properties.
