or steam systems, or less than -300F in a cryogenic application. As the pipe heats and cools it moves due to thermal expansion. Pipe flexibility and pipe supports must accommodate this movement. Pipe is attached to equipment, which has a limited capacity to support the pipe.

TIG Welding Introduction - Download PPT. In the TIG welding process the arc is formed between a pointed tungsten electrode and the workpiece in an inert atmosphere of argon or helium. The small intense arc provided by the pointed electrode is ideal for high quality and precision welding. Because the electrode is not consumed during welding, the ...

Cryogenic grinding is the act of cooling or chilling a material and then reducing it into a small particle size. Cryogenic grinding technology can efficiently grind most tough materials and can also facilitate cryogenic recycling of tough composite materials and multi component scrap. The term "cryogenics" originates from Greek word which means creation or production by means of cold.

Welding. The coefficient of thermal expan-sion is an important factor when welding two dissimilar base metals. Large differences in the CTE values of adjacent metals during cooling will induce tensile stress in one metal and com-pressive stress in the other. The metal subject to tensile stress may hot crack during welding…
