TongFengflex manufactures unique tubing that is relied on in numerous industries. The tubing is produced by helical coiling of a cold-rolled metal strip onto a spindle, with the helical coils being linked with each other by means of a special type of strip profile. Basic materials for the strip are stainless steel. However, other metals are also available.
Applications:Instrumentation tubing is used by manufacturers of various industries, such as Process & Control Instrumentation, Measuring & Controlling Devices, Analytical Instruments, Medical Instruments and many others with specific applications including temperature measuring, wiring conduit or armor cable and protective casing.
Instrumentation tubing is made in two configurations, or constructions, commonly called SquareLok and InterLok, and is often abbreviated as SL and FI.
Technical Data: SquareLok Style (SL)
SquareLok tubing is produced from a continuous metal strip, and is held in position by locking one leg of one profile over the leg of the adjacent profile.
