Yuri Gagarin State Technical University of Saratov (SSTU) has presented a new method that can increase the durability of gas distribution networks. The university's scientists have proposed using polyethylene reinforced pipes that can withstand high operational loads and ensure the reliability of pipelines for up to 50 years. The solution allows reducing costs by 25-30%.
Scientific research conducted at SSTU has confirmed the advantages of polyethylene pipes compared to steel counterparts. Internal pressure, temperature deformations, and external influences were tested during the trials. The researchers were able to establish optimal design characteristics to ensure durability.
The study showed that reinforced polymer pipes withstand high operational loads. Calculations, field and laboratory tests made it possible to determine the optimal design parameters, ensuring the durability of pipelines over a horizon of up to 50.
In addition, the use of polyethylene pipes has environmental benefits. A 40% reduction in carbon dioxide emissions compared to steel pipes is achieved by eliminating welding, reducing the amount of earthworks, and reducing energy consumption during production.
