Gaskets, Bolting & Sealing
Flanged joints are only as reliable as their gaskets and bolting. We supply ring-type joint gaskets to API 6A and ASME B16.20, spiral-wound and kammprofile gaskets, flange insulation kits for cathodic protection, and stud bolts and nuts with PTFE, zinc-nickel or Xylan coatings, including sour-service bolting with controlled hardness.

Gaskets, Bolting & Sealing: FAQs
What is the difference between R, RX and BX ring gaskets?
R rings are oval or octagonal gaskets for ASME and API 6B flanges. RX rings are pressure-energized versions of R rings used in API 6B flanges up to 5,000 psi. BX rings are pressure-energized gaskets for API 6BX flanges from 2,000 to 20,000 psi, where flange faces make contact.
Which bolting is used for sour or low-temperature service?
ASTM A193 B7M / A194 2HM (hardness limited to 22 HRC) is used where bolts are exposed to H2S. ASTM A320 L7 / A194 Gr 7 is used for low-temperature service, and A193 B7 / A194 2H is the general-purpose grade.
