There are three types of hoses for this use:
• Delivery hose with no spiral and abrasion resistat (from ship to land).
• Suction (full vacuum, -1.0 Bar) and delivery hose spiraled and coated flanges (under the water surface).
• Elinda hose normally made in short lengths and big sizes, with rings (for a maximum flexibility) and rubber flanges.
This kind of hoses are used for:
• Dredging (suction and delivery) of lakes, in the sea and for mining.
• In alternative for DELTA in case of heavy duty (high pull resistance and therefore chemical connection).
• Compounds like DELTA.
