Matter regarding flame arrestor breather valves
Thread Content
Dear teachers, we are planning to issue a tender for a batch of storage tank vent valves. The data sheet provided by the design institute specifies that they should be flame-arresting vent valves. May I ask the teacher: Does this breathing valve already come equipped with a flame arrester, so there is no need to purchase one separately? Is that so? Thank you!
Breather valves with built-in flame arrestors are available for purchase
A flame-arresting vent valve indicates that it already has flame-arresting functionality, so there is no need to purchase a separate flame arrester.
Yes, a flame-arresting breathing valve is a breathing valve that comes equipped with a flame arrester. When specifying the requirements for such purchases, in addition to meeting the relevant process requirements, the flame arrester built into the breathing valve must also comply with relevant standards and specifications and pass corresponding flame-arresting tests: For flame and blast arrestment, stainless steel should be preferred as the material for the flame arrester, and it must meet the test requirements specified in current international standards such as ISO16852 and national standards such as GBT 13347; third-party test verification documents must be provided, and the pressure drop should not exceed 0.3 kPa.
