Eliminates multi-component flange kits and field assembly errors.
Hydrostatically and electrically tested to 1.5× pressure.
Built for long service life in demanding environments.
Prevents electrochemical corrosion from impressed external currents.
Available from ½” to 150” nominal pipe size, manufactured to ANSI, ASME, API, DIN, ASTM, BS, UNI, and NACE standards. Each unit undergoes hydrostatic, dielectric, insulation resistance, NDE (UT & MT), and dimensional verification to ensure compliance and operational safety.
