Stainless steel tubing. Quality. Customized to the core.
Tube welding and forming depends on the grade and application specifications. At Teshima, we use TIG Welding System, a process ideal for small diameter tube fabrication. Steel sheets enter a welding machine where they are coiled and welded. When the steel sheets enter the machine, they are formed to a coil. These coils are then welded at the seam to form a tube. The standard material used in stainless steel is 304, 304L, 316 & 316L. Teshima Corp., has plans to increase capability of materials being used in future.
Welding Process
Drawing Process
Floating/Drawing process of pulling a metal bar, rod, or wire through the hole of a die to alter its finish, shape, size, and/or mechanical properties. This tube drawing technique reduces the outer diameter, inner diameter, and wall thickness of the tube. The integrity of the surface of the tube is maintained, ideal for stainless steel tubes.
Annealing
Annealing is the process of heating metal above re-crystallization and cooling back to room temperature. When metal is formed to shape, the molecular bonds tighten, making the metal stiff. To restore ductility, the metal is processed through annealing machines. At Teshima International Corp., we specialize in the annealing of stainless steel. With ten annealing machines in our factory, orders are processed quickly and efficiently.
Tube Sinking is a drawing process that shrinks tubes to a smaller diameter. In this drawing method a tube is processed through a die without a mandrel inserted. With a mandrel, good inner surface quality is not guaranteed. The outer surface integrity is determined by the die angle. The die used gives a standard surface. A tube can be shrunk down to a significant value of its original size. Tube sinking is perfect for jobs where cost is critical.
