<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Bending electropolished tubing can be acceptable as long as one is careful in the process, and keeps the bending radius to no less than 10x the tubing diameter.
Electropolishing tubing leaves the internal surfaces of the tubing more brittle, and a hard bend of less than 10x the tubing diameter can cause microfractures in the surface. These microfractures can cause particles to break off the internal surfaces and become
entrained in the gas stream.<o:p></o:p></span></p>

Hi tom,<br>
<br>
A local company here can bend coaxial tubing. They quoted me 4800$ for the 2 lines BCl3 and SiCl4.<br>
<br>
What do you think of bending ? They told me the 1/4 wasn’t kinked at all.<br>
