PERIODICAL CHECKS
24 hours after the first commissioning, check the connections to the pipe and especially
ensure the flange bolts are tightened to the correct torque. Inspect the valve every year by
verifying its wear and replacing any damaged parts.
Periodically verify any phenomena of internal and/or external corrosion and/or erosion as
they may significantly damage the pressurized parts by locally reducing the thickness and
as a consequence the safety degree.
