There are several advantages, and one concern to be aware of, when using thin wall stainless tubing, depending upon your applications. For instance, this type of tubing does help improve fluid flow rates any time you are working with a variety of liquids. Because the inside diameter is slightly larger than regular wall, fluids are able to pass faster from one end to the other. Delivery rates can be adjusted using different approaches, including reducing the amount of pressure placed on the fluid, or using a longer section of tubing.
Another advantage to using thin wall stainless tubing is it makes it much easier to pass viscous materials through the tubing. Any type of material which is sticky, thick, or greasy may get clogged or stuck in regular walled tubing. But, again, because the inner diameter is larger, these materials are able to be moved through the tubing easier and help avoid them from becoming clogged.
The main concern you need to know about has to do with bending the tubing to a desired angle. Because the wall is thinner than regular walled tubing, extra care has to be taken to prevent breaking or crimping the tubing. Often, it is recommended for this type of secondary finishing operation to use regular wall tubing in the desired inner diameter opening by switching to a different gauge size. In the event you must use a thin wall and require it bent, just remember it can take longer to complete this process, as special care is needed to maintain the integrity of the tubing.
