SYSTEM AND METHOD FOR USING BENT PIPES IN HIGH-PURITY FLUID HANDLING SYSTEMS

摘要

A novel method for bending tubes suitable for use in high-purity fluid handling systems includes selecting a tube made from a material having a grain-size number of at least 5, and forming a bend in the tube with a bend radius of greater than 1.5 times the diameter of the tube. Tubes bent according to the present invention are incorporated into high- purity systems as supply lines, product lines, and vacuum forelines, without the need for post - bend heat treatment or polishing.
