How much will it expand in being heated from 32 F.? 3. Make a rough sketch design for a 6" Armstrong hydraulic joint, pressure 800 lbs. per sq. inch; give the principal dimensions. 1 When this occurs, there is always the possibility of the stress being increased in the internal layers, owing to the presence of the pressure water, and rupture of the press may happen at a pressure sensibly below the one it was designed for. A slight leakage will often take-up (or rust-up) after a few days by rusting of the pores. This is usually the bottom end of the cylinders. Sketching Exercises. 4. Sketch in fairly good proportion three examples of cast-iron flanged joints for steam pipes. 5. Show by sketches three examples of how copper steam pipes are fitted with gun-metal flanges. 0. Show by sketches (a) a mild-steel solid drawn pipe with cast-steel flanges; (6) a welded iron pipo with riveted flunges. 7. Show by neat sketches the following joints used for tubing: ordinary socket, Perkin's, I'erkin's joint with copper washer, and Emery's joint for connecting a steel tube to a gun-metal nozzle. 8. Sketch the following: boiler tube and ferrule, boiler stay-tube with backnuts, boiler tube with Admiralty ferrule. What is about the ordinary diameter and thickness of the last-mentioned tube? 9. Show by sketches the usual form of union joint. Under what conditions of working are these joints used? 10. Sketch three different expansion joints suitable for steam pipes, and say which you would prefer, and why. 11. Sketch an ordinary spigot and socket joint suitable for a cast-iron water pipe. Why is this type of joint most suitable for...
