Turbine casing flanges are sometimes provided with a system of joint grooving to __________.

🔍 Key Concepts

• Steam turbine casing construction and how upper and lower halves are joined • Purpose of grooves, serrations, or joint grooving in high‑pressure flanged joints • How steam sealing and pressure containment are achieved at casing joints

💭 Think About

• Think about what happens at the split line of a high‑pressure turbine casing if there is any leakage path between the two halves. • Consider whether grooving at the joint would tend to improve alignment, sealing, or clamping force—and how it would do that physically. • Ask yourself which option matches the typical function of multiple small grooves or serrations in pressure-containing machinery joints.

✅ Before You Answer

• Verify how labyrinth seals normally look and where they are usually installed on a turbine (rotor vs casing joint). • Consider whether flange bolting or grooving is primarily responsible for contact pressure between casing halves. • Recall whether alignment of casing halves is usually achieved by dowel pins, fit surfaces, or grooves in the joint face.
