The Castiglioni S.r.l. company prides itself on more than 30 years of experience in the field of stainless steel capillary-tubes without soldering.
The company represents for all its customers the best result of the most advanced tecnology of the last years.
For this reason we have succeded to achieve an excellent finishing and a great precision in our drawings thanks to the high quality of our steels and thanks to the specialization acquired through continuous experience and studying.
The qualitative level we have reached allows us to supply a wide variety of stainless tubes having the following features:
 a perfect linearity and uniformity of thickness,
inside surfaces with an average ruggedness of Ra 0.6,
outside diameters gauged and polished with small tolerance,
gratest resistence to inner pressure and electronic control of each tube.
All the stainless capillary-tubes are realized through cold-drawing and, traditionally, they are offered in straight bars without being heated. On request we can make supplementary treatments of annealing and solubilizing.
