Good opportunities

A l’époque au niveau des bureaux d’études de la SNTF et notamment celui des anciens ateliers du Hamma il y avait une structure qui était chargée de l’intégration nationale … structure qui a malheureusement disparue … SNTF gagnerait à créer une structure au niveau centrale qui doit piloter et créer les conditions de nature à développer l’industrie ferroviaire avec des partenaires nationaux publics ou privés (comme ENCC, Ferrovial, etc…) et des partenaires étrangers détenteurs de technologies … ces partenariats créeront les conditions favorables pour tisser un véritable réseau de sous traitants garantissant la disponibilité de la piece de rechange (notamment les pièces stratégiques et de consommations courantes) condition sine qua none pour assurer une maintenance de qualité … une disponibilité , une fiabilité et la durabilité du matériel … Plus important encore …l’autonomie nécessaire pour réduire autant que possible l’importation de la PR et la dépendance de l’étranger …! #SNTF #Transport #Ferroviaire #XMT #HamidOUAR #Adjoutdjamel https://lnkd.in/dnNMHDCi

****************************************************** UNIQUE FEATURES OF SWRO PLANTS UMM AL HOUL EXPANSION SWRO PLANT - QATAR A VERY UNIQUE DESIGN OF SW SUPPLY ******************************************************** The construction of intake for the RO expansion was a very significant constraint for implementing project due to the new environmental permits required for the construction, and the project execution schedule which could jeopardize financially the new infrastructure development. The Power and existing Desalination Plants intake did not have enough capacity to provide the seawater supply required for the RO expansion Plant (30,000 m3/h) with the level of redundancy required for reliable design. The Power Plant intake consists of eight (8) cooling water pumps with one (1) common spare for providing a seawater flowrate of 930,000 m3/day for each of the four condenser lines. The EPC Contractor ACCIONAA developed an innovative proposal for supplying 30,000 m3/h from the cooling water headers to feed the RO expansion Plant and balancing the seawater subtraction flow with the brine reinjection from the two (2) RO Plants. The total mass balance resulted in 20% of the cooling water flow being RO brine and an increment in the salinity of the cooling water to the condensers of 15%, the condenser vendor´s warranty was updated with the new salinity. The slight increase of temperature in cooling water lines due to the brine reinjection did not impact on the design of the existing cooling system. Alternative operational scenarios were studied, control valves and flowmeters were installed on the brine pumps discharge and an overflow of total capacity was required in the brine pit to cope with all the production scenarios of the power plant and variations in sea water temperature.

Une excellence de la production industrielle Algèrienne qui mérite d'ètre saluée et d'etre prise en exemple de gestion saine d'une entreprise publique. Oui, il est possible d'avoir une production industrielle de qualité en Algérie

Thick wall steel pipes have various applications in different industries due to their strength and durability. Some of the common applications of thick wall steel pipes include: 1. Oil and gas industry: Thick wall steel pipes are extensively used in the oil and gas industry for transporting oil, gas, and other fluids over long distances. These pipes can withstand high pressure and are resistant to corrosion, making them suitable for the demanding conditions of the industry. 2. Construction industry: Thick wall steel pipes are used in construction projects for structural purposes. They are commonly used in the construction of buildings, bridges, and other infrastructure. The high strength and load-bearing capacity of these pipes make them ideal for supporting heavy loads and providing stability. 3. Water supply and drainage systems: Thick wall steel pipes are widely used in water supply and drainage systems. They can handle high water pressure and are resistant to corrosion, ensuring the safe and efficient transport of water. These pipes are also used for sewage disposal and wastewater treatment. 4. Mechanical and engineering applications: Thick wall steel pipes find applications in various mechanical and engineering industries. They are used in the manufacturing of machinery, equipment, and components that require high strength and reliability. These pipes are also used in the automotive industry for manufacturing exhaust systems and chassis components. 5. Power generation: Thick wall steel pipes are used in power generation plants, including thermal power plants and nuclear power plants. They are used for transporting steam, water, and other fluids in the power generation process. These pipes can withstand high temperatures and pressures, ensuring the efficient operation of power plants. 6. Mining industry: Thick wall steel pipes are used in the mining industry for various applications. They are used for transporting minerals, slurry, and other materials in mining operations. These pipes are also used for ventilation systems in underground mines. 7. Offshore and marine industry: Thick wall steel pipes are used in offshore and marine applications, such as oil rigs, offshore platforms, and shipbuilding. These pipes are designed to withstand harsh marine environments, including saltwater corrosion and high pressure. More information,pls visit:www.hgsteelpipe.com Email:sales@hydrograndsteel.com
