90° Elbow Frequently Asked Questions
Q: What is the difference between a short radius and long radius 90° elbow?
A: A short radius 90° elbow has a center-to-end dimension equal to the pipe diameter, making it more compact. The long radius version has a center-to-end dimension 1.5 times the pipe diameter, offering better flow characteristics and reduced pressure drop. The choice depends on space constraints and flow requirements in your system.
Q: How do I select the right material for my 90° elbow application?
A: Material selection depends on several factors: the fluid being transported (corrosive, abrasive, or high-temperature), pressure requirements, environmental conditions, and budget. Stainless steel offers excellent corrosion resistance, carbon steel provides strength for high-pressure applications, while PVC is cost-effective for low-pressure water systems. Consult with our technical team for specific recommendations.
Q: Can 90° elbows be used in high-pressure steam systems?
A: Yes, specially designed 90° elbows rated for high-pressure applications can be used in steam systems. They must meet ASME standards for pressure ratings and should be constructed from materials like forged carbon steel or stainless steel that can withstand high temperatures and pressures. Always verify the pressure-temperature rating chart for your specific elbow model.
