Should professional-grade fully threaded studs be used for both toxic and flammable media? Is this requirement too high? In reality, none of them are installed with such standardization, right?
For the connection of toxic and flammable media, safe and reliable threaded studs must be selected to ensure the reliability and safety of the connection. Choosing professional-grade fully threaded studs can better meet this requirement. Although in practice there may be some cases where installation is not carried out to such standard levels, this does not mean that it is correct to neglect safety issues. Therefore, we should still adhere to the relevant regulations and standards as much as possible to ensure the safety of operations. .
This is a standard requirement. In practice, none does anything other than this. Bolts cost so little – why take such a risk?
Why are threaded studs safer?
Who says that in reality there isn’t anyone who does this? Nonsense! Is it a matter of money?
In the old flange standards, as well as in the selection criteria for piping components used in the petrochemical industry, only the pressure rating and temperature are specified for choosing bolts and nuts; the hazard level of the medium is not taken into account. As a result, some people still use double-headed bolts for flange connections in pipelines carrying toxic or flammable media； However, the new flange standards do not allow this; it is recommended to use fully threaded bolts in accordance with the new flange standards ；
