3. FAQ: EN 10216-2 10CrMo9-10 Seamless Steel Tubes

(1). What testing is required for compliance?

  • Hydrostatic testing: Verifies leak-tightness.
  • NDT: Ultrasonic or eddy current testing for defects.
  • Mechanical/chemical tests: Validate composition and properties.

(2). What's the Manufacturing Process?

  • Seamless Tube Production:

Hot Extrusion: Heated billets forced through a die to form hollow shells.

Rotary Piercing: Billets rotated and pierced by a mandrel to create seamless tubes.

Cold Drawing: Optional for tighter dimensional tolerances and smoother surfaces.

  • Heat Treatment:

Normalizing: Heated to 890–950°C, air-cooled to refine grain structure.

Tempering: Reheated to 680–730°C, followed by air cooling to balance strength and ductility.

(3). What is the application?

  • Power Plants:

Superheaters/Reheaters: Operate at 540–580°C, 150–250 bar.

Steam Pipelines: Transport high-energy steam to turbines.

  • Petrochemical:

Catalyst Tubes: In reformers, handling hydrogen at 500–600°C.

Heat Exchangers: For hydrocarbon processing.
