S is the allowable stress in (psi) So, what does Schedule 80 means?.

To simplify the piping thickness indication system ASME (American Society of Mechanical Engineers) committee has developed a “Schedule Number” system based on modified Barlow’s wall thickness formula. This is the standard method to define the thickness of pipe in the process plants. The unit of wall thickness measurement for a pipe is “ Schedule“. For example, 4″ pipe is simply mean as DN 100 4. Here you have to note that DN is the way to indicate pipe size in “mm”. What is pipe DN (Diameter Nominal)?ĭN or Diameter Nominal is an International indication and also the European equivalent of NPS to indicate pipe size. NB is just an American way to refer to pipe size.

Basically, there is no difference between NB and NOS. NPS is a frequently used term for referring to the size of a pipe. NOTE: This is to note that after 14″ pipe size, its outer diameter and NPS have the same value. Generally Pipes for any pipe system to be used as per design and Piping standard codes.

There are some terms related to pipes that are important to know by all piping engineers. Used of different metal pipe are designed as per pressure and fluid flowing through it.

Typically metal pipe is made of Steel or Iron such as Carbon steel, Stainless steel, galvanized steel, ductile iron, brass, and alloy steel. Pipes are made out of Metals, Ceramics, Plastics, concrete, and fiberglass. Pipes can be defined as: “ A metallic or non-metallic cylinder used to convey fluids or transmit fluid pressure.” A pipe is normally a tubular section but its shape is not restricted to a circle. The main part of any piping system is Pipes which are used to convey materials. More to Read: An Overview on Different type of piping drawing used in Piping Project Construction What is Pipe? Equipment, eg: Pumps, Vessels, Heat exchanger, Ejector etc.Instruments, eg: Pressure indicator, Temperature indicator, Flowmeter etc.Valves, eg: Gate valve, Globe valve, Ball Valve, Butterfly valve, control valve etc.Elbow, Tee, Reducers, Flanges, couplings etc. Piping also contains many different types of components like: Interconnected Pipes subjected to the same set or sets of design to fulfill the purpose of fluid transportation using different flow control and measurement methods. Generally, most people are familiar with plumbing as it constitutes water transportation in every home.
