Stainless Steel Mechanically Polished Tubing, 2.5 in. OD by 0.065 in. Wall, NW63 & ISO63 flanges

Vacuum buttweld fittings are designed to be used in any vacuum applications where minimizing the number of sealed joints is critical. We sell stainless steel vacuum tubing by the foot, in up to 10 foot sections. A cut service fee of $35.00 applies to tubing cut to the customers required length. We also offer a tube facing service of $35.00 so that the tubing is perfectly flat on the ends for superb fusion TIG welds. This tubing is made of 304 stainless steel and is mechanically polished. This is vacuum grade tubing, which is typically used for welding on NW63 and ISO63 flanges or used in vacuum process lines. This tubing has 2.5 inch outer diameter, 0.065 inch wall thickness, and is mechanically polished.

Applications:

  • Semiconductor wafer fabrication areas for remote installations and below a raised floor
  • Permanent house vacuum lines
  • Vacuum utility lines for vacuum fixtures
  • High temperature lines
  • Burn box exhaust lines

Vacuum Tubing Features:

  • Low outgassing under vacuum
  • Chemically resistant
  • Annealed for consistent leak free welding
  • Minimized corrosion concentration points

General hints for good vacuum welds include:

  • 1. Always start with clean and properly weld prepped components.
  • 2. For internal welds, minimize warping by using only enough heat for 60-75% penetration.
  • 3. For external butt welds, make sure they are 100% penetration with no internal cracks or crevices.
  • 4. Do not weld internally then externally around the entire circumference of the fittings.
  • 5. Make sure there is little or no gap between pieces to be welded.
  • 6. Insure that all surfaces affected by the heat of the weld, especially the vacuum side, are purged properly with inert gas.

Common Specifications:

  • Outer Diameter: 2.5 inch
  • Wall Thickness: 0.065 inches
  • Finish: Mechanically Polished
