The casting technology makes it possible to produce pipes with a diameter of up to 1 metre and a length of up to 6 metres for the needs of housing and utility services, oil and gas production, as well as fire extinguishing. In the near future, it is planned to test a new high-strength alloy developed by RUSAL, which will provide aluminium pipes with the same mechanical strength characteristics as steel and cast-iron pipes.
The price of aluminium pipes is comparable to that of high strength cast iron products. Notably, the weight of aluminium pipes is 3 times less than the weight of cast iron analogues. This ensures a reduction in the cost of transportation and installation of pipelines, which is especially important for difficult access area.
‘Aluminium alloys have better corrosion resistance compared to unalloyed cast irons and steels, as a dense and hard oxide film is formed on the aluminium surface protecting it from destruction. Such advantages allow us to forecast that centrifugally cast aluminium pipes in the near future will become widespread in many industries along with steel and cast iron pipes,’ said Roman Andryushin, Deputy CEO of UC RUSAL for Sales in Russia, the CIS, and China.
In the long run, it is possible to arrange the production of high-strength aluminium centrifugally cast pipes with a capacity of more than 10 thousand tonnes of casting per year at the production facilities of Lipetsk Pipe Company Svobodny Sokol.
Thanks to RUSAL’s pricing policy and the conclusion of long-term contracts with suppliers with a fixed premium for processing in 2021, domestic high-tech aluminium products such as pipes, lighting poles, noise screens, helicopter platforms, cables and other products, previously not produced in the country and imported from abroad, began to be more actively introduced in the domestic market.
