Failure modes to watch for
Every guide in the Pilkington (NSG) Custom-engineered tin baths up to 60 m long library lists the candidate root causes its procedure rules out. These are the distinct failure modes we've documented so far, a useful starting point if you don't yet know which specific alarm or symptom you're chasing.
Bath seal at the glass entry or exit lip worn or poorly fitted, allowing air ingress
Protective gas (N2/H2) supply pressure drop allowing atmosphere reversal
Top roller seal degraded, creating a gap for air to enter along the roller shaft
Tin bath roof panel joint or expansion joint opened from thermal cycling
Heater element burnout in one zone, leaving a cold streak across the ribbon
Thermocouple failure giving the controller a false low reading and causing overheating in one zone
Tin level below the design value, reducing thermal mass and amplifying local temperature variations
Heater power circuit fault limiting the zone output

How to diagnose bath temperature profile upsets on a Pilkington float glass tin bath
A bath temperature profile upset means one or more heater zones are not delivering the design heat input. Check the heater element continuity and thermocouple calibration before adjusting any setpoint.
How to detect and respond to tin bath atmosphere contamination on a Pilkington float glass tin bath
Oxygen or moisture contamination in the tin bath atmosphere oxidizes the tin surface and creates glass defects. Identify the ingress point and restore the protective gas flow before the tin surface is significantly oxidized.
How to correct top roller alignment faults on a Pilkington float glass tin bath
A top roller alignment fault shifts the ribbon off-center and creates thickness asymmetry. Adjust the offending roller angle in small increments and allow the ribbon to respond over several ribbon lengths.
