Bekaert SL8040Xb

Summary

Product identification

• Model: BEKAERT Model SL8040Xb Pressure Vessel
• Intended use: Continuous use as housing for membrane filtration elements to purify typical brackish waters.
• Accommodates: Any make of eight-inch nominal diameter spiral-wound elements, as well as many hollow fibre elements.
• Element interface hardware: Supplied with the vessel.
• ASME standards: Designed to meet the standards of the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code, Section X. ASME Code stamping available at additional cost.
• Model Numbering Scheme: AA XX XX X P where:
  • AA: Model (e.g., SL denotes Side-ported)
  • XX: Membrane diameter (80 = 8”, 40 = 4”, 25 = 2.5”)
  • XX: Membrane length in inches
  • X: Number of membranes
  • P: Pressure identification (h=1200 psi, a=1000 psi, m=600 psi, b=400 psi, f=250 psi)
  • Example: SL8040Xb indicates a side-ported vessel for 8" diameter, 40" length membranes, X number of membranes, and a 400 psi pressure rating.
