What to Know Regarding Underwater Services

Do you know that water occupies a larger space on the planet than land? Many cities border on rivers, seas, and oceans, and they send goods by water, transport people, lay pipelines under it, and build bridges. All this requires expertise in underwater services, as well as the concreting and repair of structures underwater. Concrete cutting underwater is not an easy process.

Technically, underwater activities cover rock removal, and cutting of concrete and wires. Apart from that, salvaging is also a paramount activity used underwater that can’t be ignored.

Are Underwater Services Still in Use?

If you properly think about the underwater services, you will find it a completely unique phenomenon and very difficult for some people to understand. We know that underwater cutting is associated with ultra-high temperatures and flames.

However, how can that happen in water depths where the water cools everything? In reality, a method for wire cutting underwater was found a long time ago, some centuries back, and has been in use since then. Therefore, it can’t be ignored whatsoever. We can say that it is an imperative activity that must occur.

Methods used in underwater cutting service

There are various methods of wire cutting used underwater. These methods are very different from the ones we usually know. Underwater wire cutting methods are as follows;

1. Electro-oxygen cutting

This is one of the many methods of underwater cutting that is quite economical at depths of up to one hundred meters. The wire that is being cut is heated to a melting temperature using an electric arc. Then a stream of oxygen enters through the electrode, burning the metal part and blowing out the oxides.

This type of underwater cutting is mainly used for cutting ferrous wires, and it also requires stable and high-quality electrical contact with a metal surface. This method has been in use for a long time.

2. Exothermic cutting

Just like electro-oxygen cutting, this method is based on the combustion of a special electrode in oxygen supplied through the electrode itself. In this case, the electrode burns autonomously, and the electric arc is only needed to ignite the electrode.

This technology is perhaps the most common underwater cutting method. The very high combustion temperature of the exothermic electrode allows cutting ferrous metal and concrete, including reinforced concrete structures.

Usually, underwater concrete cutting with hydraulic systems uses the powerful energy generated by the flow of fluid. To create a high-pressure flow, hydraulic oil is used, which is pumped through a flexible hose in a hydraulic pumping station.

Underwater services that comprises of cutting has a high efficiency. The hydraulic systems and tools are very reliable, compact, resistant to low temperatures, and quite easy to operate.

Verdict

Underwater services are in great demand today, as they are a very reliable and effective way in case there are emergencies in water. They are highly demanded these days since many structures are now constructed underwater as compared to ancient times where the world wasn’t evolved.
