The boat buoyancy tube has U-shaped form. The tube is separated by
means of inner elastic partitions into 3 chambers of a similar volume, each
being provided with an air fill valve.
The air fill valve is intended for:
— filling the compartment with air from a standart pump or filling system
and maintaining pressure in the tube for prolonged time,
— adjustable drop of pressure in compartment.
The air fill valve is designed as a tab-type non-return valve and consists
of the following components (Fig. 3):
— housing (1);
— cup (2) with strap (3);
— washer with gasket (4);
— nut (5);
— spindle (6) with spring (7) and cup diaphragm (8).
Also there are the following elements fitted on the tube (Fig. 1):
— doubled rubbing strake;
— safety handles;
— bow step-plate with navigation lights;
— tube polyester ends with two antiskid steps each.
The sequence of filling the pipe with air:
1. Fill one of the compartments with air to a pressure of approximately 0.1
bar.
2. Fill the other compartments sequentially with air to a pressure of
approximately 0.1 bar(1.45psi).
3. Only after that, bring the air pressure in each tube compartment to the
nominal (0.15 bar/2.2psi).
BUOYANCY TUBE.
The rated pressure value is 0.15 bar (2.2 psi).
If the tube pressure more than nominal, deflate the tube slightly. Boat exploitation with
board pressure more than nominal decreases boat service life.
Do not use compressors and/or other types of inflating equipments not approved by the
boat builder.
Check the tube pressure before every navigation.
