Frequently asked questions
What sizes are precision tubes available in?
OD 3 mm to about 127 mm (¼" to 5") typical, wall 0.5 mm to 12 mm; BWG or mm; straight lengths up to about 30 m, U-bent to drawing.
Which specifications cover precision tubes?
The product specification for the grade, with dimensions to the relevant ASME or EN standard.
What are precision tubes used for?
Cold-drawn and annealed or hard temper. Precision tubes are cold-drawn tubes with very tight dimensional tolerances and a high-quality surface for mechanical, automotive, hydraulic-cylinder and instrument applications (for example EN 10305-1 carbon steel or stainless steel to ASTM A269 / A511).
Which materials are precision tubes available in?
Stainless steel, nickel alloys, carbon and alloy steel and non-ferrous metals, depending on the specification. See the material list above.
