Routine Visual Inspections: For grooved fittings used in above-ground piping, a visual inspection is recommended every quarter; for those in buried piping, an annual inspection is advised.
Critical Component Checks:Key components-such as connection points and sealing gaskets-should undergo specialized inspections every 3 to 6 months to prevent seal failure.
Adjustments for Special Conditions: Maintenance intervals should be shortened and inspection frequency increased for grooved fittings used in corrosive environments or high-pressure operating conditions.
Under normal operating conditions, properly maintained grooved fittings can operate reliably for decades without the need for frequent parts replacement.
