Stainless steel capillary for fiber optic

To whom it may concern,

I’m writing you to kindly ask you some information about your stainless steel capillary tubes.

We are looking for capillary tubes with the following specifications:

• Outside diameter = 1 mm ÷ 1,2 mm
• Inside diameter = 0,7 mm ÷ 0,8 mm
• Length = 3700 mm  ÷ 4000 mm (not less then 3600 mm);
• Frictionless and cleaned inside as much as possible. Do you have some specification about that (processes, internal roughness etc.)?
• Material: stainless steel 316L or 314 or Inconel alloy if available
• Material state: hard

We read that you provide products for fiber optic industry, do you have some reference for fiber optic applications in harsh environment (such as high temperature, oxidative environments etc…)?

What type of packaging do you use (rolled or bar)?

For any additional information don’t hesitate to contact me.

Thank you in advance.

Best regards,

Massimo
