A delayed coker heater was studied after just 5.5 years of service to predict remaining life. Results indicated significant metallurgical degradation.

A look at a few ways that firetubes can fail, including heat-related, cracking-related, and corrosion-related, and practical considerations to prevent problems.

The key to maintaining safe and reliable operations of a coker unit is healthy heater radiant tubes. Here’s a look at the technology and methods available.

One effective way to monitor tube metal temperature is via internal oxide scale thickness measurement, especially for superheater and reheater tubes.

A proven methodology is required to measure accurate temperatures in a repeatable process to capture the full capability of IR thermometry.

Companies have developed detailed programs for managing wide range of assets. However, unsustainability negatively impacts effectiveness of these programs. Reach out to us on how we can address sustainability through digital transformation.

Leveraging and combining the correct inspection tools on complex problems can yield the best overall data and understanding of actual conditions.

This article presents two case studies that show how having a holistic approach, along with the right technology and experience, is essential to identifying smaller damage mechanisms like fretting in fired heater coils.

In order to thrive, companies need to maintain top-tier optimization and run equipment safely, reliably, and aggressively. Leveraging highly accurate thermography is one piece of the puzzle to help with these shifts.

Universally, smart or intelligent pigging is now a standard practice for the inspection of fired heater and serpentine boiler coils. Understanding this technology can greatly assist with maintenance planning and the prevention of unexpected failures.

Learn how you can safeguard integrity, reliability, instrumentation safety, and more.

This article addresses two failure events where inadequate attention to thermal fatigue led to premature equipment failure while specifying guidelines to help prevent such failures that can be a part of a plant's inspection and maintenance programs.

This article presents two cases studies demonstrating how properly conducting baseline fired heater tube inspection aids in early discovery and correction of defects, avoiding unexpected in-service failures, and more.

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...

Over the last six months, Inspectioneering has released a plethora of interesting and educational content that has been read more than 150,000 times online. In case you missed it, here's a recap.

Introducing the IGS Tube Tech rover system, the next generation in autonomous cleaning technology, capable of removing more than 90% of fouling and restoring your fired heater convection sections to their original design thermal efficiency.

This article provides an overview of the key components in establishing IOWs, the levels of IOW limits, and the basic principles and application of API Recommended Practice 584 to achieve reliable fired heater performance.

Infrared (IR) thermometry has been used for over forty years to monitor tube metal temperatures in refining and chemical furnaces. Recently, IR thermometry has been criticized in the industry for delivering inaccurate readings; however, this is...

In-service equipment failures present a considerable challenge to reliability engineers. This article presents a case study of a convection tube failure in a furnace and the analyses that were performed to understand the root cause and determine the...

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.

Achieving fired heater reliability in conjunction with meeting performance standards can be a challenging feat. Performance is a measure of the degree to which the fired heater is in an operable condition at any given time.

The following interview with Rich Roberts provides answers to some of the questions our readers have about small, specially designed pigs carrying NDE technologies that can inspect nearly every area of a tube from the coils interior surface.

Refineries and chemical plants own and operate numerous process heaters (e.g. gas reformers, CCRs, etc.) as part of the standard assets throughout the facilities. Many heater coil configuration designs are flanged at both ends; however, there are...

Industrial furnaces are used extensively throughout the entire oil and gas industry, as well as other process industries such as pulp and paper, metals and mining, chemical, and petrochemical. An industrial furnace, or direct fired heater, is a...

Various fired heater designs in refineries and chemical plants contain common headers (e.g. Arbor coil configurations, CCRs, etc.) as part of their overall serpentine coil design. Accessing the interior of individual coils through the common header...

Part 1 included a review of current tube inspection practices in convection and radiant sections of heaters/furnaces in the refining and chemical industries. The authors also presented a new inspection device combining laser image mapping of the...
