80U30

Summary

Product identification

The CodeLine 80U30 Fiberglass RO Pressure Vessel is designed for continuous, long-term use as a housing for reverse osmosis membrane elements. It is intended for desalting typical brackish waters at pressures up to 300 psi. The vessel accommodates any make of eight-inch nominal diameter spiral-wound element, with appropriate interfacing hardware furnished.

The CodeLine 80U30 is designed in accordance with the engineering standards of the Boiler and Pressure Vessel Code of the American Society of Mechanical Engineers (ASME) Code.

Precautions

• DO read, understand and follow all instructions; failure to take every precaution will void warranty and may result in vessel failure.
• DO mount the shell on horizontal members at span “S” using compliant vessel supports furnished; shim saddles if required. Tighten hold down straps just snug.
• DO align and center side ports with the manifold header. Correct causes of misalignment in a row of vessels connected to the same header.
• DO use flexible type grooved-end pipe couplings, Victaulic® Style 77 or equal, at side ports; allow full, 0.125 inch gap between port and piping, and position piping to maximize flexibility of connection.
• DO provide flexibility in, and support for piping manifolds so that vessel can grow in length under pressure without undue restraint; provide additional flexible joints in large pipes leading to manifold header.
• DO provide overpressure protection for vessel set at not more than 105% of design pressure.
• DO inspect end closures regularly; replace components that have deteriorated and correct causes of corrosion.
• DO lubricate seals sparingly, using nonpetroleum based lubricants, i.e. Parker Super O-lube®, Glycerin or suitable silicone based lubricants.
• DO NOT work on any component until first verifying that pressure is relieved from vessel.
• DO NOT make rigid piping connections to ports or clamp vessel in any way that resists growth of fiberglass shell under pressure (∆DIA = 0.015 in. (0.4mm) and ∆L = 0.2 in. (6mm) for a length code –8 vessel).
• DO NOT hang piping manifolds from ports or use vessel in any way to support other components.
• DO NOT tighten Permeate Port connection more than one turn past hand tight.
• DO NOT operate vessel without connecting both Permeate Ports internally to complete set of elements or otherwise plug ports internally so that external piping connection is not subjected to feed pressure.
• DO NOT install Spacer on downstream end of vessel.
• DO NOT operate vessel without Thrust Cone installed downstream.
• DO NOT pressurize vessel until double-checking to verify that the Locking Ring is in place and fully seated.
• DO NOT operate vessel at pressure and temperature in excess of its rating.
• DO NOT operate vessel with permeate pressure in excess of 125 psi at 190°F (0.86 MPa at 88PP0 PPC).
• DO NOT tolerate leaks or allow end closures to be routinely wetted in any way.
• DO NOT operate outside the pH range 3-10.
