Offshore engineering faces harsh environments characterized by salt spray, humidity, and high corrosion levels. These severe conditions pose great challenges to fasteners. After special coating treatment, B7 bolts gain enhanced corrosion resistance, allowing them to withstand seawater and salt spray. On offshore drilling platforms, marine transport vessels, and floating production facilities (such as FPSOs), B7 bolts are used to secure critical structural components, ensuring equipment stability and safety. Moreover, under conditions that require frequent inspection and maintenance, these bolts perform exceptionally well — their high strength and fatigue resistance reduce both maintenance frequency and difficulty.

Flange and piping systems rely on fasteners to maintain sealing integrity and safety under high loads. B7 bolts are therefore the ideal choice for various flange connections. Their outstanding durability ensures long service life and reliable operation of flange joints within piping systems. In addition, the wide range of B7 bolt sizes and shapes allows them to fit different flange specifications, providing flexibility in engineering design and equipment maintenance.

B7 bolts are not only widely used in the oil, petrochemical, and offshore engineering industries but also play a vital role in other industrial sectors. In heavy machinery manufacturing, wind turbine assembly, and nuclear power equipment, the high strength and reliability of B7 bolts create endless possibilities. Because they can withstand long-term vibration and stress, B7 bolts have be
