Plastic Steel Elbow FAQ Section
What makes Plastic Steel Elbow different from standard PVC or metal elbows?
Plastic Steel Elbow combines the best properties of both materials. The inner plastic layer provides excellent chemical resistance and smooth flow characteristics, while the outer steel layer offers superior structural strength and impact resistance. This hybrid design outperforms standard PVC in mechanical strength and surpasses metal elbows in corrosion resistance.
What is the maximum pressure rating for Plastic Steel Elbow at elevated temperatures?
The pressure rating decreases with temperature elevation. At 73°F (23°C), Plastic Steel Elbow is rated for 150 PSI. At 140°F (60°C), the rating drops to 100 PSI, and at the maximum operating temperature of 220°F (104°C), the pressure rating is 50 PSI. Always consult our pressure/temperature charts for specific applications.
Can Plastic Steel Elbow be used for potable water systems?
Yes, our Plastic Steel Elbow is certified to NSF/ANSI 61 standards for potable water applications. The inner PVDF layer is FDA-compliant and doesn't leach harmful chemicals. However, we recommend flushing the system before first use and following all local plumbing codes for drinking water systems.
