Mechanical / hydraulic

• Dimensions:
  • Overall length (with Nylon End Caps): 1156 mm (45.5 in)
  • Overall length (with Engineered Thermoplastic End Caps): 1158 mm (45.6 in)
  • Diameter (from diagram): 356 mm (14.0 in)
  • Additional dimension (from diagram): 298 mm (11.7 in)
• Weight (approximate):
  • With Nylon End Caps:
    • Dry: 62 kg (136 lbs)
    • Water-filled (shellside): 97 kg (213 lbs)
  • With Engineered Thermoplastic End Caps:
    • Dry: 54 kg (118 lbs)
    • Water-filled (shellside): 89 kg (196 lbs)
• Liquid Flow Guidelines: 16 – 91 m³/hr (70 – 400 gpm)
• Pressure Guidelines (X50 or X40 Fiber):
  • Maximum Shellside LIQUID Working Temperature/Pressure:
    • 5-25°C, 7.2 barg (41-77°F, 105 psig)
    • 50°C, 2.1 barg (122°F, 30 psig)
  • If no vacuum is used, 1.0 barg (15 psig) can be added to pressures above.
  • Maximum Applied Gas Pressure: 4.1 barg at 25°C (60 psig at 77°F)
  • Note: Liquid pressure should always exceed gas pressure. Maximum applied gas pressure is for integrity testing; normal operating pressures are typically lower.
• Flange Connections:
  • Shellside (Liquid Inlet/Outlet):
    • 4 inch class 150 raised face flange per ANSI B16.5
    • 100A 10K raised face flange per JIS B2238
  • Lumenside:
    • 2 inch class 150 raised face flange per ANSI B16.5
    • 50A 10K flat face flange per JIS B2238
