Case Study: SÄKAPHEN Lining of Pipework
SÄKAPHEN Si14E Lining of Meter Prover Spools
Meter Prover Manufacturer
Scope of Work
Internal Lining of Meter Prover Pipework
The Meter Prover Spools were grit blasted internally to a cleanliness standard of Sa3 in accordance with ISO 8501-1:2007 with an average surface profile of 40 to 60 microns. The lining is applied from solution in a series of thin layers, with an air dry period between coats and a low temperature stoving to assist solvent release and part polymerise the resin. Conventionally, 25-40 microns are applied at each coating application.
When the lining has attained the specified thickness and continuity, the final cure is completed by placing the component in the stoving oven and raising the temperature to 200°C. The exact duration and the rate of temperature rise will depend on the mass and wall thickness of the construction. The lining is tested for thickness, continuity and cure when cool.
One of the SÄKAPHEN range of thermal hardening SÄKAPHEN Resins, SÄKAPHEN Si14E is an unfilled Phenol Formaldehyde resin lining applied to pipework, heat exchangers, condensers, storage tanks, meter provers, pumps, turbines, fans and other metal fabrications operating at temperatures up to 180°C in certain cases.
