Generally ASTM A320 Grade L7, B7, and similar high-strength alloy steel fasteners. It is preferred to increase connection safety in cold environments.
Because it is manufactured from annealed alloy steel and undergoes special heat treatment high impact resistance They win. This ensures that connections work without cracking even at low temperatures such as -50°C.
Energy, chemical, natural gas, LNG facilities, pipelines, and pressurized tanks It is used in critical areas that require low temperatures and high security.
