Why pipe supports need half round pad design
In marine engineering, corrosion of pipeline supports is generally prevented by preventing accumulation of water
Benefits:
1. Avoid contact of stagnant water with the pipe surface, especially the anti-corrosion coating is very afraid of water
2. It is not conducive to check the corrosion of the pipeline support, especially the visual inspection and non-destructive inspection.
3. Metal-to-metal contact is prone to electrical corrosion (even if the material is the same)
4. Due to the semicircular structure design, the contact area between the bracket and the pipe can be reduced to a minimum. Eliminate cracks in the pipeline coating.
But on the market, all round rods are bought and cut with a jig. They have the following disadvantages
1. A round rod material is slightly less resistant to pressure, especially chinese round rods. Even if Japan and other imported round bars are
2. Cutting is easy to cause uneven cutting and easy to bend
inject with POM+ glass fiber is used for leakage corrosion, its compressive strength far exceeds that of peers
