Titanium Flange Type and Flange Sealing Surface

    Recently, one of my client inquired titanium flange to me, I asked him flange type but he gave me FF. In fact, FF is sealing surface not flange type. So I think maybe I should put emphasis on titanium products also, not only titanium materials. 

    Then let's learn about the titanium flange information more together.

     1. Flange Type:
        
         1.1 PL FLG - Plate Flange
