Introduction In piping design, selecting the correct pipe thickness is one of the most fundamental engineering tasks. Pipe thickness directly affects pressure containment, mechanical strength, corrosion life, safety, and project cost. In Oil and Gas Piping, chemical plants, refineries, and power plants, pipe thickness is not chosen arbitrarily. It is calculated using ASME B31 codes, … Read more
Introduction In piping design and piping engineering, correct identification of every pipeline is extremely important. In large plants such as oil & gas facilities, chemical plants, refineries, and power plants, thousands of pipelines carry different fluids under different pressures and temperatures. To manage this complexity, piping engineers use a Line Designation system, also known as … Read more
In any process plant, pipes are more than just hollow tubes carrying fluid. They are pressure-containing components expected to work safely for 20, 25, sometimes 40 years. During that life, corrosion is not a possibility — it is a certainty.That is where corrosion allowance comes in. As a piping engineer, understanding corrosion allowance is one … Read more
When you first step into a plant site or start reading piping drawings, everything may look confusing—pipes going everywhere, strange symbols on drawings, and many unfamiliar names. Over time, you realize that a piping system is not just pipes. It is a collection of piping components, each with a specific role. Understanding piping components is … Read more
When someone starts learning piping engineering, one of the first and most important topics they must understand is piping materials. In real plants, most piping problems do not happen because of poor drawings, but because of wrong material selection. Over the years, I have seen leaks, cracks, corrosion failures, and even shutdowns—all linked back to … Read more
If you are new to piping engineering, or even if you are working in the field for a few years, you will often hear terms like NPS, DN, and Schedule. Many beginners get confused and sometimes even experienced engineers mix these terms during discussions. I will explain NPS, DN, and Pipe Schedule in a very … Read more
Introduction piping engineering practice, the terms piping and pipeline are often used incorrectly. However, from a design, code, and safety point of view, piping and pipeline are two different systems. Understanding this difference is essential for correct engineering decisions. What Is Piping? Piping is an engineered system used to transport fluids inside a plant or … Read more
