PIPE & TUBE
Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid.
Generally, industrial piping engineering has three major subfields:
Piping material
Piping design
Stress analysis
The material with which a pipe is manufactured often forms as the basis for choosing any pipe. Materials that are used for manufacturing pipes include:
- Carbon steel.
- Low temperature service carbon steel
- Stainless steel
- Nonferrous metals, e.g. cupro-nickel
- Nonmetallic, e.g. tempered glass
There are certain standard codes that need to be followed while designing or manufacturing any piping system. Organizations that promulgate piping standards include:
ASME - The American Society of Mechanical Engineers - B31 series
ASTM - American Society for Testing and Materials
API - American Petroleum Institute
ANSI - American National Standards Institute
