Gasification technology has emerged in oil and gas due to the high combustion energy of Syngas and less environmental concerns than flue gas. This article discusses proper inspection and corrosion monitoring techniques for gasification units.

This is the second of a two-part column on “Creep.” This second part discusses the approach to creep assessment in plant equipment.

This is the first of a two-part column on “Creep”. It presents an engineering overview of the phenomena, answers the question: “What is Creep?”, and provides readers with foundational knowledge for evaluating and managing remaining...

API 579-1 is a complex document covering several different types of equipment that may contain flaws or damage. Due to its complexity, this article condenses it into six things you need to know.

Fired heaters are among the most critical equipment in refineries and chemical plants. This article provides an overview of what a fired heater tube mechanical integrity program should include.

Traditional, paper-based inspection processes can prevent plants from being as effective as they can be. By digitalizing your mechanical integrity process and data with MISTRAS Digital®, plants have realized up to 75% gains in IDMS data entry and...

This article summarizes a recent finite element analysis (FEA)-based study that employs creep simulation techniques to investigate the elevated temperature response of piping with peaked longitudinal weld seams.

Avoiding cracking under pressure when managing high-energy piping systems is common subject matter in the power industry. Just as high-energy piping can give way to pressure, stress and fatigue, so can the people in charge of operating them when...

Fired furnaces in the petrochemical and refining industry are critical pieces of equipment that can have a major impact on process unit safety, reliability, and economics. They are complex pieces of equipment, where tubes and other pressure boundary...

Metals will slowly deform under stress and higher temperatures by the mechanism known as creep. The amount of creep deformation that will be experienced is highly dependent upon the level of stress, level of temperature and material properties....

Steam reformers are an integral part of ammonia, methanol, hydrogen, and gas process plants around the world. THey are one of the highest cost, both in capital and maintenance, pieces of equipment in the plant. Typically, reformers contain several...

Reformer catalyst tubes are commonly manufactured from high strength, creep and corrosion resistant alloys. They are relatively thick walled and are usually produced by centrifugal casting. Their lives are limited by creep, driven by a combination...
