Understanding ASME Code for piping

ASME

An overview of the ASME (American Society of Mechanical Engineers) Codes and Standards which are commonly used by Engineers to design piping systems, be it oil and gas or pulp & paper or chemical plants or anything that uses the ASME Code and Standards.

If you look at a chemical plant, an oil refinery or an LNG plant, you will definitely see the pipes lined up interconnected between vessels, towers, pumps and others. Likened to pasta plus giant metal spaghetti scattered.

For someone who works as a pipe engineer or piping engineer, a good appearance is not the goal of a pipe layout design, but there is a beauty and satisfaction in seeing the rows of pipes.

Of course, there are many things that the piping engineer must pay attention to when designing. The scope of a piping engineer is not only pipes, but also includes other pipe components such as elbow fittings, reducers, flanges, valves, steam traps, strainers and many more.

ASME B31
The code used for design and construction purposes for pressure piping systems is ASME B31. Code ASME B31 Pressure Piping covers piping systems having operating pressures ranging from vacuum to high pressure. ASME B31 Code is not a book that provides detailed information about a job. However, the ASME code B31 only provides guidance on the minimum requirements for pipe fitting as intended.

ASME Code B31 consists of a number of independent “sections” and is also published separately. However, everything remains under the auspices and direction of the ASME Committee B31 Code for Pressure Piping. It is the duty and responsibility of the project owner or “owner” to decide which parts of the Code to use on their project. However, there are several things to consider in determining which part of the code to use, namely:

  1. Limitations of the Code part / section
  2. Legal requirements where it will be used
  3. Possible other codes and standards that must also be met.
