The PTFE-lined elbows supplied by Songshang are in 45°and 90°commonly. And we can manufacture 30°and 60°elbows or other degree elbows in specific dimensions required to make sure the perfect flow.
Product specification
The manufacturing process used in the PTFE-lined elbows is molding. Compared with the extrusion method, it is a processing method that is more resistant to positive and negative pressure, high temperature, and strong corrosion.
The flanges on PTFE-lined elbows can be connected in fix-loose/loose-loose/fix-fix.
