STEEL PIPES
Read more...Conveying fluids has always been an element of primary importance and  a subject of study for mankind.
The great aqueducts built by the Romans still today bear witness to the importance that has always been given to water supply, essential to the development of human civilization, and it must also be remembered that such works must be lasting in time and that the functionality of the water system is of utmost importance.
Today the technologies made available by hydraulic engineering allow the solution of any problem concerning the transport and distribution of fluids, whether they are in liquid or gas form, thanks to the use of materials with mechanical properties that can satisfy increasingly difficult and demanding working conditions, often variable over the lifetime of the pipeline.
Of the different materials that might be used in the construction of pipelines conveying fluids, steel is definitely the most commonly used, thanks to the high performance it can guarantee even when working conditions are extreme as well as persistent.
The production processes and the technologies used in the most up-to-date steelworks ensure a product of the highest quality, and guarantee the uniformity of the mechanical and metallurgic characteristics throughout the whole width of the coils used in the lamination plants.

HIGH PRESSURE API 5L PIPES

Read more...As of October 2008, the 44th Edition of the API 5L has gone into effect. This norm distinguishes two different levels of the product (product specification level) defined PSL1 and PSL2, which differ one another by the quality of the specifics required; in fact, PSL2 requires a higher quality level compared to PSL1. In general, the pipes supplied following this norm can be welded with or without filler metal, or without welding. As in the last edition of this norm, the welding process must be followed by a normalization process of the welded area and thermally altered, obligatory beginning from steel grade X42 for the level PSL1, and obligatory for all the steel grades for the level PSL2.

PRE-INSULATED PIPES
The continuous research for new technologies, aiming to contain global electricity consumption, has brought to experiment and create fluid transportation systems which are always more efficient and that aim to gain higher levels of performance.
RIVECO GENARALSIDER S.P.A. has developed technologies for internally lining steel pipes with polyurethan foam in order to guarantee high performance for fluid transportation in district heating systems and/or for combustibles to produce energy.

PREINSULATED PIPES FOR DISTRICT HEATING

Read more...The never-ending research for new technologies, aimed to solutions for energy saving, to the achievement of higher efficiencies and better pollution control on a worldwide level, have led to the testing  and construction of district heating and district cooling networks in place of localized boilers and A.C. units. These systems need transport networks for fluids  to be increasingly effective and specifically aimed to avoid energy losses.
Riveco Generalsider have developped technologies for insulating steel pipes using polyurethane foams, which can ensure high yields in the transport of fluids for district heating/cooling systems and conveying fuels for energy production.
One of Riveco Generalsider’s most important reference, which is worth mentioning, is the pre-insulation of the Val D’Agri oil pipeline, the largest project ever made in Italy, which involved the companies in the production of hundreds of kilometres of rigid polyurethane foam insulation.

POLYETHYLENE PIPES


RIVECO GENERALSIDER S.P.A. uses high level quality polyethylene for all its pipe, supplied by qualified producers externally or produced internally. Testing is performed, through systematic procedures, in conformity to the specific required. The pipes are built using the most modern plant structures, with a heat extrusion method, in agreement with the most important national and international norms, such as, UNI EN 1555, UNI ISO 4437, UNI EN 12201, etc., or according to Clients’ specifications, also in respect to the norms D.M. 24/11/84, and D.M. 11/99) and the Rules and Regulations of the Italian Institute of Plastics (IIP).
