Pipefitterとは 意味・読み方・使い方

A pipefitter (also called steamfitter) is a tradesman who lays out, assembles, fabricates, maintains and repairs mechanical piping systems. Pipefitters usually go through a mix of apprentice and trade school training. Journeyman pipefitters/steamfitters deal with industrial process piping and heating/cooling systems. Typical industrial process pipe is under high pressure, which requires metals such as carbon steel, stainless steel, and many different alloy metals fused together through precisely cutting, threading, grooving, bending and welding, whereas a plumber concentrates on piping systems for heating/cooling as well as utility liquids potable water, sewage, drains, etc. in the industrial/commercial/institutional or residential atmosphere operating at lower pressures. Utility piping typically consists of copper, PVC, CPVC, polyethylene, and galvanized pipe which is typically glued, soldered, or threaded. Other types of piping systems include steam, ventilation, hydraulics, chemicals or fuel.
