The Deadly Cost of Wrong Steel in Permafrost Let’s cut through the ice: standard carbon steel coils crack like glass at -50°C. A 2024 Arctic Engineering Report revealed 63% of pipeline leaks occur within 5 years of installation. I learned this brutally during a Siberian gas project where A36 steel welds failed at -45°C, delaying […]
