[MW:1768] Flare purge associated risks - Material for Pilot tip and components exposed to flames

Please take a note of below important note I found:

Dear All,

Though not directly involved with intense process issues, I read with interest the discussion on purge gas options and reference to API-537/ISO 25457 evoked my this writing.

This is inform based on my suggestion, API-537/ISO 25457 in their latest 2008 editions, have included SS-310H as an additional material for Pilot tip and components exposed to flames.

You must consider using SS-310H in lieu of SS-310.  Please review your company's specifications. I am sure it may be age-old SS-310.

SS-310H with tightly controlled carbon (0.04% to 0.10%) as against 0.25% max for SS-310, offers increased temperature resistance, an extra margin of 150 to 200°C over SS-310.

In future, I wish to give more such un-solicited advice, if found useful by members. I enjoy writing to international bodies for improvements to codes and standards. I am rather against writing too much company specific codes and standards.
