Long pipelines

ELINSUBCA, brings experience and knowledge in the installation of pipes Submarines High Density Polyethylene (HDPE) with the support of the prestigious Norwegian factory Pipelife, to supply pipes in Long mode Tranches in large diameters different projects be developed on the Atlantic coast of Latin American and Caribbean.

The manufacture of pipes, solid wall is made up of 2,500 mm diameter, through direct the ocean thanks to the strategic location of the plant Pipelife Norge AS at the seaside continuous extrusion. The pipe sections are prepared in lengths up to 550 m, sealing the ends with standing flanges to be towed and delivered to their final destination where they will be installed by the contractor.

The towing method is executed directly by the factory, to be effective and safe, with more than 50 years of experience running several large projects around the world. This system provides great advantages in reducing time and costs of implementing projects Emissaries, Tomas and Aqueducts Submarines.

In the range of services offered ELINSUBCA, it is the engineering, procurement and installation of pipes for transporting liquids and accessories, valves and special components. To address the multiple operating conditions in industrial use, ELINSUBCA works with different pipe materials including found HDPE (High Density Polyethylene) and PP (polypropylene).

Materials HDPE (High Density Polyethylene) and PP (polypropylene) are especially important in this area. Its high resistance to chemicals, its wide range of high temperature applications and easy installation are just some of the main advantages of these plastic.

Within the specialty of ELINSUBCA in installing underwater pipelines and the installation of pipes for industrial systems, the large variety of different components that comprise it, allow selection of materials, plus a wide range of diameters and lengths through different techniques by thermal fusion welding such as butt fusion, socket or electrofusion, which are particularly suitable for construction of plants.

Industrial applications

The application fields to which we are dedicated encompasses a virtually unlimited range for the following installations:

• Petrochemical industry.
• Desalination systems.
• Water treatment systems.
• Mining industry.
• Thermal power stations.
• Irrigation systems.
• Process wáter.
• Cooling system.
• Fire Systems.
• Aquaculture farms.
• Aqueducts drinking wáter.
• Sewage wastewater networks.
• Among others.

 

In most industrial processes exist liquids and gases, cold and heat, increasing the field of application of these materials, ranging from water pipes cooling piping in plants, pressurized systems to transport media to pipes for elimination of contaminated waste water, waste gas and piping systems in the construction of equipment and containers.

The experience has been obtained in HDPE piping installation in cooling systems, at lower temperatures, offers advantages in heat conduction, reducing the condensation of the liquid and therefore energy losses. Comparisons have been established along with steel pipes in terms of thermal capacity and HDPE offers advantages, however, it is advisable to use insulation and “jackets” for decreasing heat losses.

The success of a project Emissary, or Aqueduct Collection Underwater depend primarily on the construction methods should be designed according to geographical conditions, local resources and existing environmental regulations. Knowing in advance how the installation of the pipeline will take place both on land and at sea; his lying, release, transport, subsidence and positioning on the seabed, ensure efficient engineering design and successful execution in work under the parameters: Scope, Time, Cost, Quality, Resources, Risk, Procurement, Safety, Health and Health.

 

Constructive Design Methodology

ELINSUBCA you design your constructive methodology in the terrestrial and maritime part and evaluates the most suitable alternative implementation, mainly considering local resources and environmental regulations. Based on the extensive technical experience executing works of submarine pipelines in High Density Polyethylene (HDPE) designed the construction methods under criteria: Scope, Time, Cost, Quality, Resources, Risk, Procurement, Safety, Hygiene and Health We can intervene in all stages of the project or particularly required in order to define the most appropriate solution from the environmental point of economic, technical and stage designs cONSTRUCTIVE METHODOLOGY ELINSUBCA appropriate considering the following aspects :
