Can polyethylene be used to build structures related to the marine industry ?! The high variety of polyethylene products has made it possible to use these materials in various industries. Due to the low cost and available raw materials, manufacturers make a large part of their products with polyethylene materials. The popularity of polymeric materials in the manufacture of shipping and marine parts is increasing. Follow us to the end of this article to get acquainted with the types of polyethylene marine structures and the advantages and disadvantages of each.
All kinds of polyethylene products
The production and manufacture of products related to the marine industry is very expensive and therefore polymer structures are used as a suitable alternative for the manufacture of various products in the marine industry. In this section, we will discuss some of the most common polyethylene products used in the marine industry.
Floating dock: Wharves are used for mooring ships, boarding or disembarking passengers, unloading cargo, etc. Wharfs fall into different categories depending on the type and material of the hull, and polyethylene floating wharves are one of the newest types of these widely used offshore facilities. Floating berths are floating on the surface of the water without any base or common connections.
Transportation, handling and expansion of polyethylene docks is easily possible due to the modular structure. Floating docks made of polyethylene are suitable options for building seafront promenades such as floating restaurants and coffee shops.
High flexibility and adaptability to floods, wave turbulence, tides, recyclability, easy transport and maintenance, strong against weight and high pressure, resistant to algae and the sun’s ultraviolet rays, high density with the possibility of spreading over sea level The best advantages of floating docks are polymer.
Polyethylene pipe (PE pipe): Pipes made of polyethylene are one of the most widely used products in the marine industry. These pipes are used to transfer fluids from the space inside the river and the sea. Other applications of polyethylene pipes include the transmission of optical fibers into the sea, desalination, as well as the cooling systems of power plants built on the seabed. The design of polyethylene pipes must be done with great precision and high flexibility against strong waves and strong sea currents.
The need to periodically evacuate air from inside the pipe, the possibility of scaling in the long run, etc. are some of the problems of polyethylene pipes used in the marine industry. The connection of polyethylene pipes used in the seabed is done in several ways, including lip welding, flange connection, extrusion welding, and gasket seam connection.
High resistance to corrosion (against seawater), low wear, long life and no leakage in the joints, possibility of fusion and environmental compatibility of marine organisms are the most important advantages of polyethylene pipes. Used on the seabed or river. It is worth noting that marine polyethylene pipes have a high resistance to various weather currents.
Unlike their metal counterparts, these pipes do not rust at all. The possibility of damage to the interior of the pipes by destructive bacteria is almost zero. Pipes made of polyethylene, like other structures of this material, have a high resistance to harmful rays of sunlight. The process of transporting and installing marine polyethylene pipes is very easy due to its high flexibility and low weight. It goes without saying that the cost of maintaining and repairing various types of pipes made of polyethylene is very economical and cost-effective compared to other pipes.
Floating clamps: Floating clamps are spaced and interconnected parts that are used to ensure the strength of all types of vessels active in offshore piping operations. Floating clamps are used in fish farms, rubies, oil and gas industries and many more.
Plastic buoy: Objects restrained by weights and floating at sea level to warn swimmers, ships and other means of sea transport are called buoys. Swimmer buoys (in various forms), inhibitory buoys, waveguide buoys and parametric and guide buoys are among the categories of buoys used in the marine industry. Due to various advantages, some of the buoys are made of polyethylene materials and suitable for use on the seabed.
Fish farming tub: The use of sanitary polyethylene tubs has been well received by Mai farmers in recent years. These bathtubs are produced with excellent quality and generally as a single layer and can be used in the aquaponic integrated system. In addition to the aquaculture process, the use of polyethylene baths is common in other industries.
Rescue ring: Rescue rings are divided into several categories: military, commercial and passenger, and LIFE RING. As the name implies, they are used to rescue people at sea. The capacity to build rescue rings is determined by the type of vessel (vessels that use these rings) and the number of people (people who need a rescue ring).
Fish breeding cages: One of the new and widely used methods in fish farming is the use of fish farming cages. By enclosing seawater, dams, etc. in the water bed, these cages make it possible to raise fish without the need to build a separate space. Fish farms are made with four advantages and are available in four types: fixed, floating, submersible and submersible.
The possibility of construction in different volumes and dimensions, depending on the customer’s order, is one of the advantages of different types of fish breeding cages. Fish cages also need bases made of polyethylene, and in fact the cage bases are located in the subset of fish cages. Light weight, high flexibility, adaptability to salt water and the ability to produce in different colors are the outstanding features of the bases of fish farming cages. It should be noted that it is possible to produce fish cage bases in various dimensions.
