8. FAQ: Professional FAQ on Tube punching

Q1: What materials can be processed through Tube punching?
A: Common materials include carbon steel (ASTM A179/A513), stainless steel (304, 316L), copper, and aluminum. Selection depends on mechanical property, corrosion requirements, and end-use. All comply with global material certifications (e.g., EN 10217, ISO 9443).

Q2: What accuracy and tolerances are achievable?
A: State-of-the-art tube punching achieves hole position tolerance of ±0.05 to 0.1mm, as required in heat exchangers, automotive and process equipment, following ISO 2768-f/H standards.

Q3: Which standards regulate tube punching products?
A: Key standards include ISO 9001 (quality management), ANSI B46.1 (surface texture), EN 10217 (pressure tubing), and customer-specific criteria. Factory audits (e.g., SGS) and certified QC are best practice.

Q4: What is the typical surface roughness and finishing for punched tubes?
A: Standard finishes are Ra ≤ 0.8~1.6μm (smooth, clean edge, suitable for sealing, non-clogging). Advanced options: passivation (for corrosion), powder-coating, or sandblasting per project needs.

Q5: How to ensure minimal deformation and edge burr?
A: Using optimized die geometry and post-punching deburr machines, burr height is reduced to ≤ 0.05mm. Tool design and punching force are calculated for wall thickness and material type, per EN 10305 pipe standards.

Q6: What about installation and welding standards for tube-punched components?
A: Installation relies on accurate hole reproducibility and minimal distortion. For pressure systems, compliance with ASME B31.
