For the gas buffer tank designed and manufactured by our company (with a maximum operating pressure of 2 MPa, an operating temperature of 45°C, and a working medium composed of 8% CO2, 39% H2, 28% CO, 22% N2, etc., and a volume of 20 m3), can commercial-grade flange bolts be used?

The medium is a flammable and explosive gas; for safety reasons, it’s better to use a combination of high-strength bolts and nuts

Bolts cannot be used at this time; instead, double-headed studs should be used, and those of commercial grade will work as well. Of course, it's better to use a dedicated-grade one.

Agree with the person above – the mechanical properties of those studs are much better than those of bolts
