Many tube mills offer a low cost alternative to seamless
tube by producing a welded tube and then cold drawing over
the weld. For coiled tube, some mills join shorter lengths
together with orbital welds in an attempt to approach our
length capability.
Although it may look similar to the untrained
eye, the changes in the microstructure as a result of welding
cannot be overcome by subsequent cold working and heat treating.
In fact, this method can mask flaws in the weld seam resulting
in failures under pressure or premature corrosion.
Camdel
Metals offers a "True Seamless" product
with no welds at any point in the manufacturing process.
The integrity of the tube and its resistance to corrosion
are superior to any welded or welded/drawn tube.
The true
seamless nature of our product applies to all tubing produced
in coil or straight length form.
