BSF
1 / 5
Maintains high strength even below -60℃, preventing brittle fracture. Suitable for liquefied natural gas pumps, liquid nitrogen pumps, and similar equipment.
Carbon steel or alloy steel with a body-centered cubic crystal structure can have hardness and impact performance optimized through tempering heat treatment.
Stainless steel fasteners possess both corrosion resistance and excellent mechanical properties in low-temperature environments.
Wind turbine bolts are designed to withstand multi-axis stress and dynamic loads while avoiding brittle fracture at low temperatures.
The low-friction coefficient design facilitates easy installation and disassembly in low-temperature environments, reducing operational complexity and downtime.
Rocket fuel storage tanks, liquid hydrogen/liquid oxygen pipeline connections. Wind tunnel models employ low-temperature locking devices that enhance connection stability through the thermal contraction effect.
LNG storage tanks, transport ships, and pipeline flange connections (working temperatures as low as -162°C). Liquid nitrogen/liquid helium storage equipment.
Cryogenic support structures of superconducting magnets (such as those in MRI equipment). Cryogenic thermostats of quantum computers operating close to absolute zero.
Fixed shelves for ultra-low temperature cold storage (-80°C). Liquid nitrogen quick-freezing equipment conveyor belt fasteners for industrial food processing.
