ASME PCC-2 is a post-construction code that provides comprehensive guidelines for the repair and alteration of pressure equipment and piping, covering both welded repairs and mechanical repairs. For the safety of both the system and the personnel involved in its repair and maintenance, it’s important to adhere to the guidelines laid out in the code. […]
The Importance of a Good Plot Plan in an Industrial Plant In the design and operation of an industrial plant, one of the most critical elements is the creation of a good plot plan. A plot plan refers to the detailed, scaled representation of the physical layout of the plant’s components. It serves as a […]
API 570 establishes requirements to maintain the safety and integrity of piping systems already in service. This code is not a substitute that replaces the original design code used for the development of the piping systems. It defines in-service inspection procedures, line condition monitoring, repair, and maintenance, ensuring accurate and timely evaluations to ensure operation […]
Let’s consider, for example, a fully pressurized pressure vessel with a load applied on the nozzle as shown in the picture. This load creates a bending stress (secondary stress) at the nozzle-to-head juncture. In the left-hand side of the nozzle, this load creates a tension strain value ε1 (see below), somewhat beyond the yield strain […]
In industry, ensuring the safety, durability, and efficiency of systems is crucial, and pressure testing plays a vital role in achieving this. They are essential for verifying the structural integrity and sealing capacity of piping systems and equipment under pressure. The process involves subjecting a component or system to a pressure greater than its normal […]
The ASME B31 committee is responsible for codes and standards that cover design, materials, manufacturing, assembly, erection, quality control, inspection, testing, as well as operation and maintenance of piping systems under pressure. Until a few years ago, there was no specific section within this committee for hydrogen piping systems. B31.3 – Process Piping and B31.8 […]
