Welded and redrawn tubing in stainless steel, titanium, nickel and zirconium alloys.

Welded and Weldrawn Tubes

Our weldrawn tube manufacturing process begins with cold rolled strip of metal, roll formed into tubular shape and seam welded without the use of any filler material. The as-welded tube is then reduced in size several times through various cold working techniques until reaching the exact size, tolerances, and temper our customers require.
Welded and Weldrawn Operations

Our manufacturing process employs a combination of value-added steps to produce the highest quality tubing that meets the exact specifications supplied by our customers. Tubes can be created in a variety of different sizes and shapes from a wide range of alloys. Process includes:

  • Degreasing/cleaning
  • Annealing
  • Straightening
  • OD belt polishing / grinding
  • ID grit blasting
  • Stamping / labelling
  • Packaging
  • Shipment
  • Forming and welding
  • Pilgering
  • Tube rolling
  • Cold drawing
  • Sink drawing
  • Rod drawing
  • Plug drawing
  • Shaping

Cold Working

After each cold working cycle the tubes are cut, cleaned and heat treated in preparation for the next cold working step. Before reaching final size, our weldrawn products will undergo a minimum of two draw cycles reducing their cross-sectional area by at least 40% after welding.
