Diver umbilical with pneumo & gas hose and cable
A diver umbilical with pneumo and gas hose and cable is a bundle of hoses and cables that connects a commercial diver's helmet to the surface control panel. The umbilical typically consists of three main parts:
- Pneumo hose: This hose allows the surface team to provide the diver with air pressure information, such as depth, time, and decompression stops.
- Gas hose: This hose supplies the diver with breathing gas, usually a mixture of air and helium or oxygen.
- Cable: This electrical cable transmits audio and video signals from the diver's microphone and camera to the surface.
This buoyancy umbilical tube is made of a 6.3mm inner diameter sounding pipe, a 8.3mm inner diameter main air pipe and a special underwater reinforced four core shielded telephone line, which are wound into a Fried Dough Twists shape. Both ends of the umbilical cord are equipped with connectors, which can be directly connected with the diving mask, diving telephone and air distribution panel. The special underwater four-core shielded telephone cable has been specially strengthened and has enough breaking force (more than 400 kg). Its good bending performance prevents the belt from excessive bending and knotting. The D-shaped ring at the underwater end is equipped with a two-stage quick hook. The breaking force of the main gas pipe is greater than 500kg, the working pressure is 500psi, the bursting pressure is 4000psi, the load capacity of the joint is greater than 90kg, and the weight per 100 meters of water is - 4kg.
It is formed by winding a main pipe with an inner diameter of 8.3mm and a special four core shielded telephone line for underwater reinforcement into a Fried Dough Twists shape. The two ends of the umbilical cord can be connected with the diving mask and the diving telephone. The water end can be connected with air source and diving telephone, the underwater end can be connected with diving mask, and the D-shaped ring at the underwater end is equipped with a quick hook. The special underwater four-core shielded telephone line is specially strengthened and has enough breaking force greater than 400kg, which can be used as a safety rope to pull the diver out of the water at a critical moment. The trachea has good flexibility, which can prevent the umbilical cord from excessive bending and knotting. The breaking force of the main trachea is more than 500kg, the working pressure is 500psi, the bursting pressure is more than 4000psi, and the weight of water is - 1kg per 100m.
