ASTM A193 B7 B7m full thread stud bolt  

    There was once a pressure vessel engineer named Xiao Ming who often struggled to choose the right fastener. In high-temperature and high-pressure environments, ordinary bolts are already unbearable, while those that are resistant to corrosion are not resistant to high pressure. Just when he was worried, he heard about the excellent characteristics of B7 fully threaded bolts.     B7 fully threaded bolt is a type of bolt that is resistant to high temperature and pressure. It can withstand high temperatures up to 500 ℃ and high pressures of 1400 bar (20000 psi), and has strong corrosion resistance. This type of bolt not only meets the American ANSI/ASME standard, but is also commonly used in industries such as petrochemical, sewage treatment, and pump valves. These characteristics of B7 make Xiaoming completely worry free.    Due to the high strength, corrosion resistance, and high temperature and pressure resistance of B7 fully threaded…
