Roxar Retrievable WLC Holders and Coupons are installed in high pressure 2#8221; hydraulic or mechanical access fittings. Coupons are pre-weighed prior to installation in the flow and - after an exposure period - cleaned and weighed again. From measured weight loss, accurate corrosion rates are calculated and deposits, bacteria and corrosion data collected, effectively combatting the dangers of corrosion.
