What are piping classes?
Piping class or Pipe Class is a document that specifies the type of the components such as a type of pipe, schedule, material, flange ratings, branch types, valve types and valve trim material, gasket, and all the other components specific requirements to be used for different fluids under different operating …
What are piping systems used for?
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.
What is piping and why is it important?
A piping system is crucial to any process plant; hence it needs to be designed with precision and care. The efficiency of a plant highly depends on its ability to transport fluid through the pipes to various equipment that function collectively.
How are pipes classified based on wall thickness and material?
Pipe is normally designated by a ‘Nominal Pipe Size’ (NPS) based upon the ID (inside diameter) of the most common wall thickness while the tube is designated by the measured OD (outside diameter).
What is pipe class and schedule?
“Schedule” PVC pipe is an older style of labeling pipe based on the standard dimensions of ductile iron and steel pipe ie. “Class” pipe is a different labeling system. Rather than categorization by wall thickness, the “class” designation rates the internal pressure that the pipe can take instead.
What is the grade of pipe?
3.2. 1.2 Grades of steel used
| Pipe grade and yield strength | Pipe wall thickness required (in.) | MAWP (psi) |
|---|---|---|
| Grade B (35,000 psi) | 0.337 | 3774 |
| Grade X-42 (42,000 psi) | 0.237 | 3185 |
| Grade X-46 (46,000 psi) | 0.219 | 3219 |
| Grade X-52 (52,000 psi) | 0.188 | 3120 |
What are the two main purposes of a piping system?
Piping systems are used to transport all known liquid or gaseous fluids, for pasty materials or pulp and for fluids in suspension, covering the whole range of pressure and temperature used in industrial applications.
Which code is used for process piping?
B31.3 Process
Learn how to design safe process piping systems that meet the international standard – American Society of Mechanical Engineers B31. 3 Process Piping Code. The American Society of Mechanical Engineers’ (ASME) B31. 3 Process Piping Code is considered to be the international standard for piping in processing plants.
What is the difference between pipeline and piping?
The pipeline is series of straight pipe welded together over a long distance. For example, the West-East Pipeline in China is 8,200 KMs longs. Piping is a complex network of pipe & fittings within the defined boundaries of the plant.
What are the different types of pipes commonly used?
Different Types of Pipes.
- Cast Iron Pipe:
- Galvanized Iron Pipe (G.I).
- Wrought Iron Pipe.
- Steel Pipe.
- Copper Pipe.
- Plastic Pipe.
- Asbestos Cement Pipe.
- Concrete Pipe.
How is a pipe class included in a piping specification?
Pipe class is part of the Piping specification. Shortcode is used to cover all the information applicable to the given pipe class. This pipe class is also included in the line number so that field construction engineer can easily identify the material required. Check the link for the example of a piping class specification.
What do you need to know about piping material?
It summarizes the piping material requirements for pipe, fittings, flanges, valves, and all other piping components for each specific pipe class as applicable to specific fluid service. The piping classes apply to bulk piping components and do not cover specialty items identified on engineering data sheets.
What is the piping material selection guide for Process Systems?
The Piping Material Selection Guide for Process Systems, as the title states, is a guide for the piping engineer who is faced with the challenge of choosing the correct piping materials of construction. The list of codes and standards in ASME B31.3 that apply to process plant design is huge, and it is impossible to cover them all in one book.
What is the role of a piping material engineer?
A piping material engineer’s role is driven by codes, standards, technical data, and catalogued information. When asked a questionIbelievethat,ifpossible,theanswershouldbesupportedwitha copy from the relevant source of information. This allows recipients to file the information, makes them more confident, and protects the piping material engineer.
