AISI 304 Bright Annealed Stainless Steel Precision Instrumentation Tube

Our AISI 304 Bright Annealed Stainless Steel Precision Instrumentation Tube is manufactured to ultra-tight dimensional tolerances for critical hydraulic, pneumatic, and analytical instrumentation applications where precision and reliability are non-negotiable.

Key Features

  • Ultra-Tight Tolerances: OD tolerance ±0.05mm and wall thickness tolerance ±0.02mm ensure consistent flow characteristics and perfect fitting compatibility.
  • Small Diameter Specialization: From 3mm to 25.4mm OD, covering the full range of instrumentation tubing requirements.
  • Bright Annealed Surface: Heat treatment in controlled atmosphere produces a bright, clean, oxide-free surface ideal for sensitive fluid and gas handling.
  • Cold Drawn Precision: Cold drawing process achieves superior dimensional accuracy, surface finish, and mechanical properties compared to standard welded pipe.
  • Coil Supply Option: Small diameters (3mm-12mm) available in continuous coil form for automated processing and reduced joint requirements.

Applications

Essential for hydraulic control systems, pneumatic instrumentation lines, capillary tubes in analytical equipment, chromatography systems, medical device tubing, precision flow measurement, and high-pressure sensing lines in process control industries.

Quality Assurance

Manufactured to ASTM A269 and EN 10305-1 precision standards. Each batch includes laser micrometer dimensional inspection reports, eddy current testing, and surface roughness measurements. Full material traceability with heat number marking on every tube.
