Custom TP304 TIG Stainless Steel Welded Tube,304 stainless tubing

Stainless steel strip is roll formed and welded in an inert gas atmosphere. No filler materials are used.

• The tubing is drawn through a die and floating plug or mandrel for initial wall sizing.

• Subsequent draws (with or without floating plugs) occur for final sizing, added strength and ID / surface finish requirements.

• Secondary processes such as straightening or annealing are completed.

The welding is completed in an inert atmosphere (proprietary formula), which minimizes oxidization and any potential added impurities. One of the T.I.G. method's advantages is its forgiving weld zone which allows strip with minor edge imperfections to join evenly during the welding process. Alternate methods with smaller weld zones can be subject to weaknesses in the seam from production setup errors, slight manufacturing process variations or raw strip with manufacturing deviations. Since our method uses no filler material, the chemistry of the selected alloy is consistent throughout the tube.
