Impurities in Ultra-Small Diameter (USD) tubing, such as oil, grease, and other foreign material left over from the manufacturing process, can result in cross-contamination and inaccurate sample readings in chromatography applications. To prevent this, conventional tubing requires additional cleaning prior to installation. But for many end users, figuring out a way to effectively clean stainless-steel tubing in long lengths and with such small diameters is a big challenge.

Here’s how we overcame this issue:

Cleaning In Coil Form

As tube length increases and the inner diameter (ID) decreases, the pressure needed to push any media through coil tubing skyrockets. As a result, standard cleaning methods and equipment aren’t always effective in cleaning high-precision USD tubes.

Our proprietary cleaning methods effectively degrease USD coil tubing several hundred feet long. After a tube is drawn, lubricant on the outer diameters is removed by our degreasing process. The tube is then subjected to high pressures to remove ID lubricants.

In addition, specialized cleaning equipment allows us to process small-diameter tubing in long coils. This ability to clean in coil form significantly reduces the amount of cleaning time required by OEMs and end users who would otherwise have to flush each straight length individually.
