FARROWTESTED tubes have passed t h e most searching test of all, a non-destructive eddy-current test t h a t probes for and detects injurious defects. On a production basis, the magic eye of FARROWTEST looks deep within t h e tube wall, is calibrated t o reject tube with defects as shown in t h e table below. Defects t h a t pass internal fluid or gas pressure tests, which cause a premature failure. FARROWTEST® is offered as a n alternate to other less positive tests a t no increase in cost! Carbon steels produced to ASTM specification A-214; stainless steels to A-249. Both include eddy-current test requirements. As a tube buyer and user, you owe it t o yourself and your company t o get t h e facts firsthand. ELECTRUNITE® Heat Exchanger Tubes are being production tested on FARROWTEST equipment every day. I t is there for you t o see. Additionally, Republic has performed "autopsies" on all types of tube which FARROWTEST has rejected. T h e hidden defects are there for you t o inspect a t our Cleveland mill. Specify FARROWTESTED Republic E L E C T R U N I T E H e a t Exchanger Tubes and get quality you can measure.
