Types of Valves in Piping oleh Gustavo Cinca

Types of Valves in Piping
Types of Valves - Tables to estimate man-hours of assembly.
This publication describes the types of traditional valves used in piping systems. The book includes, as a supplement, tables with records of man-hours required for the assembly of threaded, flange, butt welded and wafer valves. Valves are expensive mechanical devices that control the flow and pressure within a system or process and are essential components in any piping system that carries fluids. In this manuscript the main characteristics of the most used valves and the man-hours required for their assembly are indicated.
