Max WovoX (a WovoLiner® Product) is an ultra-flexible, extensible liner uniquely bonded to a seamless impermeable PU coating. The circular-knitted construction of polyester and elastomeric yarns make it ideal for transitioning several diameters and lining around multiple bends up to 90°.
TECHNICAL DATA:
Coating: PU
Carrying Material: Seamless PE circular-knitted felt with
elastomeric yarns
Installation: Inversion and Pull-In-Place
Recommended Curing Method: Ambient, heat or LED light cure
Resin Compatibility: MaxPox®, VertiPox® Epoxy Resin Systems
and MaxLight® UV Resin Systems (or approved equal)
DIAMETER RANGE:
2″ – 8″ stock diameters
2” expands to 3”, 3″ expands to 4″, 4″expands to 6″, 6″ expands to
8″, 8″ expands to 10″
THICKNESS RANGE:
2.5 mm & 3.5 mm
AVAILABLE MANUFACTURER LENGTHS:
164′ and 328′ stock lengths (+/-)
Custom longer lengths available.
APPLICATIONS:
• Open-End (Blindshot) with Calibration Tube
• Close-End
• Pull-in-Place
• Transitioning sizes / change in several diameters
• Multiple bends up to 90°
INSTALLATION:
Refer to Field Installation Sheet for resin calculations
Vacuum: -0.4 bar
Calibration Roller recommended gap setting: Thickness of liner x 2 + 1 mm for standard, thickness of liner x 2 + 2 mm for transitions
Installation air pressure: 5 to 6 psi (may need additional pressure to invert around bends).
Curing pressure: 6 to 8 psi. Consult with MaxLiner regarding dimensional changes and curing methods.
Heat curing: 120-185°F without CalTube, must use CalTube when steam curing.
Vacuum level shall meet or slightly exceed inversion and curing pressure. Always use a vacuum with proper vacuum gauge and regulator.
Always use a guide tube to contain unsupported liners from radial expansion.
STORAGE/HANDLING: Avoid extremes of temperature • Freezing may cause the coating structure to degrade locally, especially areas where the coating is in tension or compression – at bends and edges, and immediately adjacent to seam welds. • Recommended storage temperature 40°F – 95°F. • Shelf life at this temperature: in excess of 1 year. Avoid extremes of humidity • Very high relative humidity (especially at high temperature such as tropical countries) will accelerate the degradation, consequently reducing the shelf life. • Recommended storage humidity 25% rh – 65% rh. • Shelf life at 65%, 95°F: in excess of 1 year. Avoid prolonged wet storage As with high humidity, the coating is more susceptible to degradation at higher temperatures, and even further susceptible if pH of liquid in contact is significantly above or below 45°F. Wet storage is not recommended. Avoid direct sunlight Prolonged exposure to the sun’s ultraviolet light will accelerate the degradation of the coating. Store away from direct sunlight, preferably in dark conditions. Mechanical damage should be avoided • Ensure that liner is not placed directly onto grit or gravel floor – sweep and cover floor first. • Ensure personnel are instructed not to walk on or smoke around the liner. • Handle with care and ensure safe transport at all times • Ensure any rollers are clean, and the liner is not in contact with any sharp edges or snags anywhere during use. Chemical attack Avoid prolonged contact with solvents and chemicals
