The nuclear power plants under construction and under planning in my country are mainly pressurized water reactor nuclear power plants with mature technology and safety. The seamless steel pipes used in the construction of pressurized water reactor nuclear power plants and the manufacture of mechanical equipment can be divided into four categories, namely carbon steel/carbon manganese steel/low alloy steel, chromium-molybdenum steel, stainless steel and nickel-based alloy. Among them, stainless steel seamless pipes are used in key components such as nuclear power plant (coolant) main pipelines, coolant-related primary loop pipelines, steam generator heat transfer pipes and steam drain lines.

High-speed rail and EMU brake devices are equipment used to slow down or stop trains to ensure driving safety. The train brake device consists of an air supply system and automatic brake valve installed on the locomotive, brake machines and basic brake devices installed on the locomotive and vehicle, and brake pipes (also known as brake pipes) that run through the entire train. Air brakes (brakes) rely on compressed air to push brake shoes (understood as brake pads) to press against wheels or brake discs to achieve braking purposes. The entire brake system is filled with compressed air. There is no leakage in the pressure test for 15 minutes.
