The stainless steel tube optical unit is manufacturered by laser welding-drawing at gas protecting technique, the line possesses of drawing process and on-line eddy-current detection which play an importance of detects screen to get rid of dummy welding, leak welding etc.
The stainless steel tube with inner plastic sheath optical unit is manufactured by ideally combining the well-rounded optical fiber second coating craftwork with the advanced laser welding sttel tube technique. It could effectively protect fibers from burr and sawtooth etc. and precisely control the fibers excess length, and increase the horizontal fluid penetration characteristic of stainless steel tube.
The al-covered stainless stee tube optical unit is manufactured by ideally combining the advanced laser welding steel tube technique with continual extrusion & cladding Al tube technology. It could effectively increase the elctric characteristics such as short-circuit current and lighting, and evidently increase corrosion and crush resistance.
