Frac Pump Bolts and Nuts

Frac Pump Bolts and Nuts are the core fastening components of fracturing pumps in oil and gas production, designed for working conditions. They are mostly made of high-strength alloy steel, and after heat treatment, the tensile strength can reach more than 1200MPa, which can withstand pulse pressure and severe vibration of up to 100MPa in fracturing operations. ​

This type of fastener adopts a precision thread design, combined with a self-locking structure or anti-loosening coating, which can effectively prevent loosening under high-frequency impact. The bolt head is usually hexagonal or dodecagonal, which is convenient for quick disassembly and assembly in a small space using special tools, shortening equipment maintenance time. ​

In order to adapt to the complex environment underground, some products will also undergo surface anti-corrosion treatment, such as galvanizing, phosphating, or Dacromet coating, which can resist corrosion from sulfur-containing media and extend service life. In terms of assembly accuracy, its tolerance control is strict to ensure a close fit with the fracturing pump cylinder, valve box, and other components to reduce the risk of leakage.​

As the "joint" of the fracturing system, the reliability of Frac Pump Bolts and Nuts is directly related to the safety and efficiency of the operation, and is an indispensable key component in oil and gas extraction equipment. Valve box accessories, various models, are locally stocked and interchangeable.
