Steel Coil Reinforced Tubing

• The most common braid/coil material is 304V stainless steel. Both round and flat wires are available. Common wire sizes:
Round wire 0.0010" to 0.0020"
Flat wire 0.0005" x 0.0025" and larger

• "PIC" count = per inch crosses (Braid)
"WPI" count = wraps per inch (Coil)

• Higher PIC counts improve flexibility, while a lower
PIC count increases longitudinal stiffness.

• The PIC count can be varied within a specific length to provide variable flexibility. This can also be achieved via selective laser removal of OD layers.

• Selective laser removal of Polyimide top-layers increases flexibility and helps in secondary processes & assembly.

• Coil reinforced designs offer better overall flexibility.

• Axial reinforcement provides added tensile strength and minimized elongation.

• Band swaging
