Why ASTM A350 LF2 Class 1 for Blind Flanges
ASTM A350 LF2 Class 1 is a widely used low-temperature carbon steel grade for flanges and fittings. It offers:
- Good toughness at low and moderate temperatures
- Stable mechanical strength under pressure
- Excellent suitability for oil, gas, and utility pipelines
Combined with hot-dip galvanizing, LF2 blind flanges provide extended service life in outdoor or humid environments.
Hot-Dip Galvanized Blind Flanges for Corrosion Protection
The hot-dip galvanizing process creates a durable zinc layer on the flange surface, helping to:
- Reduce the risk of rust and oxidation
- Improve durability during overseas shipment
- Lower maintenance requirements in service
This makes hot-dip galvanized blind flanges Class 150 an ideal solution for pipeline isolation points in Central Asia and similar regions.
