Successfully managing heat inputs

As the years have gone by, our company has had the privilege of serving a myriad of different industries in meeting their tubing requirements. Using the likes of tube swaging, in addition to a number of other manipulation techniques, we have the means to fulfil a selection of customer specifications. Excellent for when you need a smooth, circular finish, our swaging abilities are ones that you can rely upon.

In terms of managing heat input and cooling, and by extension corrosion resistance and distortion, the welding process plays a substantial role. Traditionally, TIG welding is employed for welding stainless steel piping and tubes, and to this day, remains the principal solution for intensely high purity applications on tubes at or lower than 6-inch diameters and schedule 10 wall thicknesses. For high purity food-grade stainless steels, the favoured approach is an autogenous TIG square butt weld.

The capability to merge tubes without adding on any filler metals aids in maintaining minute heat levels and terminates any chemistry shifts, which could be introduced by the materials. This strategy usually works on any tubes that are thinner than 1/8 inches thick. As the tubing becomes thicker, in the schedule 10 to 40 scale, it then becomes mandatory to bevel the tube and attach filler metals. Tubes with tinier diameters that possess thicker walls also exist, like a 2-inch diameter schedule 80 for example. With these models, TIG is still a viable option, as changing to a wire process isn’t too practical.

At Multiform Tubes, our tube swaging makes it so that the interior of the tube is altered to another shape while the circular composition of the exterior stays the same. Additionally, this technique can also work wonders at both increasing and decreasing the tube’s diameter, enabling it to perform a host of unique functions.
