In modern industrial scenarios, B7 bolts, as high-strength fasteners, are widely used in the oil, petrochemical, offshore shipping, and other harsh working environments. Their excellent performance and broad applicability make them irreplaceable in various industrial applications.

Basic characteristics of B7 bolts: B7 bolts are made from chromium-molybdenum alloy steel and are produced through strict temperature-controlled quenching and tempering processes. This heat treatment endows B7 bolts with superior strength and heat resistance, allowing them to withstand high-temperature environments up to 500°C. The standard tensile strength of B7 bolts is typically above 125,000 PSI, far exceeding that of ordinary carbon steel bolts, ensuring reliable performance under high-pressure conditions. This level of tensile strength and high-temperature adaptability makes B7 bolts an excellent choice for high-pressure and high-temperature pipeline and vessel connections.

In the oil and petrochemical industries, equipment often operates under high temperature and high pressure, especially in refineries, natural gas purification units, and chemical production facilities. The high strength and heat resistance of B7 bolts enable them to effectively cope with these extreme conditions. They serve as critical components to ensure sealing and structural integrity in the connections of high-pressure reactors, heat exchangers, and pressure vessels. At the same time, B7 bolts are also widely used in pipeline flange connections, leveraging their superior performance to ensure stable operation of pipeline systems.
