LGF-PA66 in cold climates: minimum operating temperature?

PA66 is rated for continuous service from −40 °C to +80 °C, and the LGF-PA66 is engineered for outdo

PA66 is rated for continuous service from −40 °C to +80 °C, and the LGF-PA66 is engineered for outdoor winters in northern China. The glass-fibre-reinforced composite keeps good impact toughness at −40 °C with no brittle-fracture risk, and its low thermal contraction keeps flange seals reliable.

Compared with metal bodies, PA66 conducts heat far more slowly, so under identical insulation the media inside the measuring tube freezes less easily. Field reference: LGF-PA66 units installed above ground in Heilongjiang and Inner Mongolia rural water supply projects run normally through winter.

Two notes: below −40 °C, or whenever the media may freeze, add insulation wrapping or heat tracing; liner and seal temperature ratings must match the body — confirm the configuration with our technical team for extreme conditions.
