A193 B7 Bolts for the Oil and Petrochemical Industry

2025-11-04 09:05:25

In modern industrial applications, A193 B7 bolts, as high-strength fasteners, are widely used in the oil, petrochemical, offshore, and other harsh working environments. Their excellent performance and broad applicability make them an indispensable component in various industrial systems.

Fundamental Characteristics of B7 Bolts

B7 bolts are made from chromium-molybdenum alloy steel and undergo a precisely controlled quenching and tempering heat treatment process. This treatment endows the bolts with excellent strength and heat resistance. Typically, B7 bolts can withstand temperatures up to 500°C, and their tensile strength exceeds 125,000 PSI, far surpassing that of standard carbon steel bolts.

Such a level of tensile strength and temperature resistance makes B7 bolts an ideal choice for high-pressure and high-temperature pipeline and vessel connections.

Applications in the Oil and Petrochemical Industry

In the oil and petrochemical sectors, equipment often operates under high temperature and high pressure conditions—particularly in refineries, natural gas purification plants, and chemical production units. The high strength and heat resistance of B7 bolts enable them to perform reliably under these extreme environments.

They are widely used in the connections of pressure reactors, heat exchangers, and pressure vessels, where they play a critical role in ensuring tight sealing and structural integrity. In addition, B7 bolts are also extensively applied in pipeline flange connections, where their outstanding performance ensures the safe and stable operation of pipeline systems.
