PRODUCTS DETAIL SHOW

1. Face
Can be raised face(RF), full face(FF), Ring joint(RTJ) , Groove, Tongue, or customized.

2.Bevel end as per ANSI B16.25

3.CNC fine finished.
Face finish: The finish on the face of flange is measured as an Arithmetical Average Roughness Height(AARH). The finish is determined by the standard used. For example, ANSI B16.5 specifies face finishes within a range 125AARH-500AARH(3.2Ra to 12.5Ra). Other finishes are available on requst, for example 1.6 Ra max,1.6/3.2 Ra, 3.2/6.3Ra or 6.3/12.5Ra. The range 3.2/6.3Ra is most common.
