Checking gasket requirements — material, size, thickness, pressure/temperature rating, and application. Inspection — checking incoming gaskets for dimensions, surface defects, damage, and correct material. Installation — cleaning the flange surfaces, positioning the gasket correctly, and tightening bolts in the proper sequence and torque. Leak checking — inspecting joints during or after operation for leakage. Maintenance/replacement — removing old gaskets, cleaning the mating surfaces, and installing new ones when required. Documentation — recording gasket type, replacement date, inspection results, and any leakage or failure. Troubleshooting — investigating problems such as gasket leakage, compression damage, blowout, or incorrect installation.
