The medium is in the liquid phase, the temperature is much lower than the standard boiling point, and it does not fall into that category.
Now it’s necessary to check whether there is a gas phase space during the operation, to see if the second condition is met
It depends on whether it remains filled with water throughout operation and whether there is any gas space
It is also necessary to consider whether an FV operating condition occurs during equipment use
No, it does not meet the regulatory requirements for media that are gases, liquefied gases, or liquids whose maximum operating temperature is equal to or higher than their standard boiling point”
16Mn and 10 as specified in GB9948-2013 – both work well! All require -20 impact!
Thank you, but the purchasing department has said that in the market, pipes of type GB8163 20# are still the most common; pipes of types GB9948 10# and 16Mn need to be ordered specially. I was wondering if this is indeed the case – we have been using GB8163 20# pipes all along#
