Trawl float | type 551 | buoyancy 3230g | orange
These floats are mostly used for fishing in deep waters. Because of the strong material the range of purposes is very wide.
Product details:
- 200mm diameter
- 21mm hole diameter
- impact strength 20kg/m
- 3230g buoyancy
- max. working depth 400m
The stated characteristics of the floats are laboratory tested as follows:
Maximum working depth: The pressure corresponding to the stated working depth is applied within a period of 30 minutes and is held for 4 hours at a temperature of 18°C. (1 bar = 10 m water pressure)
Impact strength: In a factory own test procedure at a temperature of 18° C an object with the stated weight is hitting the float from a height of 1,00 m. The float has to withstand this impact.
Buoyancy: The buoyancy is being tested in fresh water. In sea water the buoyancy will be slightly higher.
Quality control: according to ISO 9001.
Laboratory tests have proved that at lower temperatures the floats can withstand a higher pressure while the impact strength is reduced. At higher temperatures this observation is contrary.
