Bekaert OI8040Xh

Summary

Product identification

The BEKAERT Model OI8040Xh Pressure Vessel is designed for continuous use as housing for membrane filtration elements. It accommodates any make of eight-inch nominal diameter spiral-wound element, as well as many hollow fibre elements. The element interface hardware for the specified element is supplied with the vessel.

The Model OI8040Xh has been designed to meet the standards of the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code, Section X. At an additional cost, vessels can be inspected during fabrication by an ASME Authorized Inspector and Code stamped.

Identification Code Breakdown:

• The model numbering uses the following structure: AA XX XX X
  • 1: Model of the Vessel (OI, SL, BK)
  • 2: Diameter of the membrane (80 = 8”, 40 = 4”, 25 = 2,5”)
  • 3: Length of the membrane in inches
  • 4: Number of membranes (represented by 'X' in OI8040Xh)
  • 5: Pressure identifications: h (1200 psi), a (1000 psi), m (600 psi), b (400 psi), f (250 psi)
• Example: OI80403m is a vessel, OI (end-ported), used to house 3 membranes of 8” in diameter, 40” in length and operating under a pressure of 600 psi.
• The OI8040Xh model signifies 1200 psi / END PORT.

Standard Specifications:

• Standard membrane length: 40"
• Standard membrane diameter: 8"

Materials of Construction:

• Shell: Glass fibre - epoxy resin (Roving-Epoxy)
• Head components:
  • Bearing plate: Hard Anodized Al 6061T6 or 6082 T6
  • Feed port: St. Steel S32750 or 31254SMO (SA 312. Designation UNS: S31254 or SA790; UNS S32750)
  • Other components including outlet adapter, sealing plate, port nut, port retainer set, securing ring, strap, saddle, locking ring set, thrust ring, head lock grove, O-rings, securing screws, and head seal are also specified in the datasheet. See the official PDF for a complete bill of materials.

Operating limits

• DESIGN PRESSURE AT 120 °F (50°C): 1200 PSI
• MINIMUM OPERATING TEMP.: 20°F (-7°C)
• MAXIMUM OPERATING TEMP.: 120°F (50°C)
• OPERATING pH RANGE: 3-11
• CLEANING pH RANGE: 2-12 (less than 30 minutes)
• FACTORY TEST PRESSURE: 1800 PSI
• BURST PRESSURE: 7200 PSI
• Permeate port pressure: Do not operate over 125 psi. Permeate pressure in excess of 125 psi must be approved by the factory prior to operation.
• This vessel is not designed for vacuum conditions.

Feed water

• Intended Use: To purify typical brackish waters.
• Application: SEAWATER
• FEEDWATERS TDS: ≤10,000 ppm MAX

Mechanical / hydraulic

• The filament-wound reinforced plastic shell of this vessel must be allowed to expand under pressure.
• The vessel dimensions vary by the number of membranes it houses. Vessels designed for 7 and 8 membranes are supplied with 3 supports. See the official PDF for exact tabulated values and detailed drawings.
• Required installation flexibility:
  • ∆DIA = 0.012 in. (0.3 mm)
  • ∆L = 0.15 in. (4 mm) for a length code 8 vessel.
• Connections: Use flexible type groove-end pipe couplings, such as Victaulic™ style 75 or equivalent fittings at each port. Allow a full 0.125 gap between each port/manifold connection.
• The Thrust Ring must be installed downstream.
• Do not over tighten the Permeate Port connection (more than one turn past hand tight will damage the port).
