Manufacturing process and quality control
The core of titanium tube manufacturing lies in addressing the challenges posed by titanium's high chemical reactivity, low thermal conductivity, and susceptibility to oxidation.
Melting: Vacuum induction/electron beam melting, with strict control of impurities (carbon, nitrogen, hydrogen) to ensure purity and toughness.
Molding:
Seamless tube: ingot casting → high-temperature piercing / extrusion → multi-pass cold drawing → intermediate annealing (to eliminate stress and prevent cracking).
Welded pipe: steel strip coiling → TIG welding or laser beam welding (LBW) → weld seam leveling.
Finishing and inspection:
Non-destructive testing: Eddy current testing (ET) for detecting weld seams and surface defects; Ultrasonic testing (UT) for detecting internal porosity.
Hydrostatic/airtight test: Ensure no leakage.
Straightness control: Ensure installation accuracy.
