HIGH PERFORMANCE COPPER PRODUCTS

Mueller Industries has tested andvalidated its Streamline COPPER tube and COPPER fittings for an operating pressure of 700PSI. The following information willgive an insight on the testing and qualifications of Streamline PERFORMANCE COPPER PRODUCTS The problem with using a proportional limit todesignate an allowable stress for COPPER isthat COPPER , unlike steel, does not have aproportional limit. Therefore any attempt togenerate an allowable stress using some % offset is misleading and inaccurate. The problem with assuming wall thickness isdirectly proportional to the operating and burstpressure of a COPPER tube or fitting is that it totallyignores the grain size and grain cleanliness ofthe cast and hard drawn tube.

7 ENGINEERED TESTING FOR VALIDATION Each test served a specific purpose but it is the collective result that provides the ultimate confidence in the strength
