Manufacturing stainless steel tubing for over 40 years How It's Made

To understand our process, read on below.

Process

Slitting

  • Performed by approved suppliers
  • Strict specifications ensure repeatability.
  • Coils supplied in long lengths

Process

Forming & Welding

Forming And Laser Welding

  • Precision roll forming mills create uniform product.
  • Defect detection is integrated into the process.
  • The strip is welded into coils in a continuous process.

Process

Plugging

Plugging

  • This process fine-tunes wall thickness to tight tolerances.
  • The floating plug smooths the finish of the ID.
  • The surface finish is determined by the percent of plugging versus sinking.
  • This is the primary technology used in Brite Draw and Matte products.

Process

Sinking

Sinking

  • The tubing’s outside diameter is reduced through a series of dies.
  • Reduction causes cold work, which increases tensile strength.
  • This is the primary technology used in K-Form products.

Process

Heat Treating

  • Heat treating tailors custom material properties.
  • Annealing relieves stress and allows for more reduction.
  • The coils are heat treated inline.

Process

Centerless Grinding

Centerless Grinding

  • This equipment can hold tight OD tolerances.
  • Grinding removes wall thickness for high OD/wall ratio designs.

Process

Straigtening

Straightening

  • A rotary straightener balances internal stress to remove coil cast.
  • Parts are visually inspected after straightening.

Process

Cutting

Cutting

We offer multiple cutting styles:

  • Shear – crimped end
  • Score break – 70-90% open
  • Electrolytic – 100% open, burr free, slight edge break
  • Laser – 100% open, burr free, sharp edge
  • Some parts can be tumbled to break edges.

Process

Cleaning

Cleaning

We offer different cleaning methods for different cutting styles:

  • Shear or score break – OD wipe
  • Electrolytic – ultrasonic: degreaser, brightened, DI flush
  • Laser – degreased, pickled, rinsed

Process

Packaging

  • Latex-free handling and packaging are available.
  • Packaging options suit different product configurations.

Final Inspection and Testing

Inspection

  • Quality and metallurgical analysis are conducted.
  • Physical properties: UTS, YS, %EL, hardness and surface finish
  • C=0, AQL sampling plan

Process

Fiber Optic Filled Tubing

  • Optical fibers are encapsulated in metal tubing.
  • Tubing provides strong, leak-free protection for optical fibers.
  • Fiber optic tubing is shipped on large spools to cable companies.
