Piping materials are the materials used for constructing pipes that transport fluids or gases.

• Piping materials can be metallic or non-metallic.

• Common metallic piping materials include carbon steel, stainless steel, copper, and aluminum.

• Non-metallic piping materials include PVC, CPVC, fiberglass, and HDPE.

• The choice of piping material depends on factors such as the type of fluid or gas being transported, temperature, pr

TIG welding uses a tungsten electrode to create a weld. The current used depends on the material being welded.

• TIG stands for Tungsten Inert Gas welding

• The current used in TIG welding can vary depending on the material thickness and type

• For thin materials, lower currents are typically used, while thicker materials require higher currents

• The current can range from 5 to 400 amps in TIG welding

The power plant can be based on various cycles such as Rankine, Brayton, or combined cycle.

• The Rankine cycle is commonly used in steam power plants.

• The Brayton cycle is used in gas turbine power plants.

• Combined cycle power plants use both Rankine and Brayton cycles.

• The choice of cycle depends on factors such as fuel type, efficiency, and power output requirements.

Gearbox is a mechanical device used to transmit power from one rotating shaft to another.
