tight joints, a gasket is usually inserted between-the contact faces of the flanges. The flange bolts then draw the faces up so tight that the'-gasket deforms into-the face imperfections and thereby provides a tight joint.
' Gaskets are made of numerous materials, such as cork,'paper, fiber, asbestos, metal (iron, steel, copper, etc.), and combinations of metal and some soft material. The proper gasket .material touse depends upon, the service of the pipe. The material-should not .be detrimentally affected by the chemical and thermal conditions of the fluid being carried.

VALVES
Valves are made with the same end connections as fittings. A brief description of each type follows.
fl*' FJanged Ends: Made in sizes from % in. up. Used whenever line fittings are nke" and if frequent removal is contemplated. Flanged valves facilitate installa
tion when large sizes are used. co *fi Screwed Ends: Most common type end. Can be used for all pressures. Usually
tinned to smaller size because of difficulty in making large screwed joints. . Welding Ends: Available in steel oniy. Generally employed for high tempera-
6 high pressure work. Difficult to disassemble in a welded line. This type in-
