Pipes for fluids, oil and gas

distribution, with a production ranging from Ø 20 to 400mm and pressures ranging from PN 6 to PN 25, according to UNI EN 1555, UNI EN 12201 and UNI ISO 4437. Pre-insulated pipes for district heating/ cooling systems and transportation of hot fuels for energy production: the combination of producing steel and HDPE pipes for conveying fluids, HDPE pipes for the sleeves and the foaming equipment makes Riveco GeneralSider a fully integrated producer of pre-insulated pipes. The company’s glass fibre fabrics are used as a mechanical reinforcement for asphalt and coaltar coatings, rock-shield protection and as anti-shearing enhancement for gloss surface coatings (such as FBE or paints) prior to concrete overweighting. The company provides full service and is also able to distribute glass fibre felt. In the second production unit (Larino, Campobasso, Italy), all kinds of anticorrosion coatings and linings for pipes up to 64" are applied: epoxy paint, PE, PP, FBE, concrete overweighting and sacrificial anodes application for offshore pipelines, rock-shield mechanical protection, polyurethane foam insulation for district heating projects and related services, and pipe-in-pipe for oil and gas applications. The company states that its most important achievement has been the accomplishment of the Greenstream Project: polyurethane coating, epoxy lining, concrete overweighting and anodes applications of a 520km long sub-sea line linking Melittah gas refinery on the Libyan Coast to Gela Terminal in the Italian coast, also known as the Libyan Gas Transmission System. Riveco had already coated and concrete overweighted a large part of the Transmediterranean pipeline conveying Algerian gas to the Italian coast from Tunisia. LGTS is the largest and most important energy project carried out in the Mediterranean, and a milestone in the worldwide energy industry. It holds the record for the deepest sea pipe lay in the Mediterranean. The company has also completed the concrete overweighting and anode application of 30km of 32" pipes linking a revamped ship acting as a floating storage and regasification terminal to the national gas distribution network onshore, and has erected a fully equipped plant at Livorno port in order to perform the job.

RIVECO GeneralSider SpA is an industrial group focused on supplying products and services to companies involved in conveying fluids, transporting energy fuels (oil and gas), and to infrastructure industries. Production is carried out at two industrial sites with a combined area of 96,000m 2 . The first production unit (Chieti, Italy) manufactures longitudinally welded carbon

steel pipes for both distribution and transport of fluids such as crude oil, gas, water and oxygen at low, medium and high pressure, in the range from 88.9 to 406.4mm (3" to 16"). The pipes are manufactured in compliance with most relevant international standards. The unit also manufactures extruded high density polyethylene (HDPE) pipes in PE 80 and PE 100, for methane and water
