Saint Ferrer® LS Series

The Saint Ferrer® ASME listed low strength components. The LS series is suitable for many ASME B31.1 Non-Boiler External Piping (NBEP) locations with ASME B16.5 flanges and most AWWA applications.

Saint Ferrer® LS-CRES Series

The Saint Ferrer® LS-CRES series is for the piping professional wanting ASME listed low strength stainless steel components. The LS-CRES series is suitable for many ASME B31.1 Non-Boiler External Piping (NBEP) locations with ASME B16.5 flanges. Limitations apply for use in AWWA applications.

Saint Ferrer® HS Series

The HS series is for the piping professional who wants to maximize the properties of all components in the bolted flanged joint to create and maintain the tightest joint. The HS Series contains ASME listed high strength materials. This series is widely used in the power and process piping industries. The HS series is suitable for many ASME B31.1 NBEP/BEP locations with ASME B16.5 flanges. Limitations apply for use in AWWA applications.

Saint Ferrer® SS Series

The Saint Ferrer® SS series contains nonlisted but allowed by strength definition.  Unlike the LS-CRES Series, these commercially available stainless steel bolts are, by specification, not required to be carbide solution treated. Carbide solution treatment extends the corrosion resistance life of stainless materials.  When used in an ASME B31.1 Non Boiler External Piping (NBEP) or Boiler External Piping (BEP), owner approval and documented analysis by an experienced piping designer is required.

Saint Ferrer® PVC Series

The Saint Ferrer® PVC Series contains low carbon zinc plated bolting designed to fit with thick PVC Flanges. Double washers are included to protect the flange from bolt and nut face indentation during installation.  This series is not governed by ASME rules for piping construction.
