Seamless annealed copper tubing for industrial applications
Annealed copper tubing is soft-state copper — it has been heat-treated after drawing to restore the ductility that the drawing process removes. The result is a tube that bends cleanly without cracking and forms to shape on site without needing a specialist tube bender for lighter gauges.
The seamless construction matters in hydraulic and instrumentation applications. A seam is a potential weak point; seamless tube has consistent wall thickness and no longitudinal joint to fatigue under cyclic pressure loading.
Applications range from low-pressure instrument sensing lines and gauge connections to higher-pressure hydraulic control circuits. The tube is compatible with standard compression fittings across common ODs — 6mm, 8mm, 10mm and 15mm are the most frequently specified in industrial work.
Cutting to length on site is straightforward with a pipe cutter; a clean square cut is necessary to seat correctly in a compression fitting. Avoid using a hacksaw unless you can deburr the cut end completely — any swarf left inside the tube will cause problems downstream.
Available in coil or straight lengths depending on the quantity required.
Frequently Asked Questions
What does annealed mean in copper tubing?
Annealed means the tube has been heat-treated after drawing to restore its flexibility. The drawing process used to form the tube work-hardens the copper; annealing reverses that hardness, making the tube soft enough to bend and form without cracking.
What is the difference between seamless and welded copper tube?
Seamless tube is drawn through a die from a solid billet — there is no join in the wall. Welded tube is formed from strip and has a longitudinal seam. Seamless is the standard for hydraulic and instrumentation lines where consistent wall thickness and pressure integrity are needed.
What compression fitting sizes suit this copper tubing?
Standard sizes are 6mm, 8mm, 10mm and 15mm OD, which match the most common compression fitting sizes in UK industrial and instrumentation work. Always size by tube OD, not bore.
