The View port has received an excellent reception from shipyards, designers and engineers as it guarantees operational reliability and safety, without any downtime normally associated with welding. Seals and protects according to Class A standards, penetrations of steel, stainless steel and copper pipes installed on ships and marine platforms against fire, gas and water.

The Use of the View Port

The View port is beneficial for the shipyards.Now, and thanks to the new certificate of homologation of aluminum structures, not only will be used in decks and steel bulkheads in large vessels and platforms, high-speed ferries, but also catamarans, fast patrol boats and other lightweight aluminum vehicles . With the ability to protect metal tubes up to 222 mm in areas classified as fire resistant A-60 and provide additional protection against water (1 bar) and gas (0.67 bar), the typical application areas where these will be used.

The Benefits

Benefits include cold and potable water lines, fire extinguishing systems and lubrication lines and hydraulic fluid. With the High-quality View ports you can actually expect the best deals available. The options are essential and that is the reason that you will have to be specific on your addressing. Of course this is a very important matter and that is the reason that you will have the proper options waiting now.

Corrosion is the interaction of a metal with an environment that surrounds it, producing the consequent deterioration in its physical and chemical properties. Likewise, it can be said that it is a natural process by which metal is altered and deteriorated through chemical or electrochemical reactions.

Types of corrosion

In the first place, it is necessary to differentiate between corrosion against the environment and contact corrosion.

Regarding corrosion against the environment, to produce it only requires that the aluminum is in contact with oxygen. The speed at which aluminum corrodes , at first, is faster than in the case of steel, due to the greater affinity of oxygen with aluminum, but once the oxide layer on the surface is formed, it acts as a shield, since it is very hard and compact, thus avoiding the progression of oxidation in aluminum. The same would not happen in the steel, since this one would continue advancing until causing the deterioration of the piece.

For this reason, although the oxidation potential of aluminum against the environment is much greater than that of iron, and that is effectively oxidized much earlier, oxidation does not progress inwards as fast as it happens in iron. Such is the protection capacity of these aluminum oxides, that have developed systems of protection -anodized- based on a controlled oxidation of aluminum pieces in order to obtain greater thicknesses of oxide and more compact, to increase its resistance to the weather .
