Instead of cuttingthreads into the ends of this tubing, thethreading is built onto tlie ends of thenew tubing, tluis increasing its capacityto withstand pressure. In this connec-tion, while a 10-gauge, 3;{.-pound pipe istested at a water pressure of 600 pounds,the 20-gauge is tested at 3,000 poundswater pressure. Mr, Lloyd asserts thathis lighter tubing will stand greater pres-sure than the heavier grades now machine as demonstrated saves about90 per cent, in labor in the production, andreduces the total cost of prfjduction byabout 50 per cent. feet of the tulic stock.
