3. Mechanical Properties (Room Temperature)

4. Dimensional Specifications

• Outside Diameter (OD): 12.7 mm (0.5") to 114.3 mm (4.5") (standard). Custom sizes up to 127 mm (5") available.

• Wall Thickness: 1.65 mm (0.065") to 12.7 mm (0.5"), per ASME B36.10M.

• Length: Random (6-12m) or fixed lengths; ends plain, beveled, or threaded.

• Tolerances:

  • OD: ±0.8% (hot-finished), ±0.5% (cold-drawn).

  • Wall Thickness: +20%/-0% (ASME B36.10M).

5. Key Applications

• Power Generation: Water walls, risers, and downcomers in coal-fired boilers.

• Heat Exchangers: Shell-and-tube configurations for steam/water systems.

• Industrial Heating: Convection banks in process heaters.

• Retrofits: Replacement tubes for aging infrastructure.

6. Testing & Certification

• Mandatory Tests:

  • Hydrostatic Test: Pressurized to 70 bar (1,015 psi) or per customer specs.

  • NDT: Ultrasonic (UT) or eddy current (ET) testing for defects.

  • Flattening Test: For cold-drawn tubes to check ductility.

• Certification: Mill Test Certificate (EN 10204/3.1 or 3.2) with heat analysis and mechanical test results.
