FAQ Section
What is the difference between short radius and long radius 90 degree elbows?
Short radius 90 degree elbows have a center-to-face dimension of 1.0 x pipe diameter, while long radius elbows measure 1.5 x pipe diameter. Long radius elbows provide smoother flow with less pressure drop, making them ideal for high-pressure systems. Short radius elbows are used where space constraints exist.
How do I select the right material for my 90 degree elbow?
Material selection depends on your application requirements: stainless steel offers corrosion resistance for chemical processing, brass provides excellent thermal conductivity for HVAC systems, PVC is cost-effective for low-pressure water systems, and carbon steel delivers strength for high-pressure industrial applications.

Can 90 degree elbows be used for high-temperature applications?
Yes, but material selection is crucial. For temperatures above 400°F (204°C), we recommend stainless steel or carbon steel elbows with appropriate wall thickness. Always verify the maximum temperature rating for your specific material and consult our engineers for extreme temperature applications exceeding 1000°F (538°C).
