Becht Engineering has industry-leading Corrosion and Metallurgical experts most with significant owner-operator experience covering the refining, petrochemical and chemical industries.  We have experts in a wide range of materials including metals, refractories and non-metallics. Becht specialists also include Chief Inspectors who work with the materials team to provide practical inspection advice.  Since our experts typically join us from long-standing careers within owner-operator organizations, we approach corrosion and materials problems from an owner’s perspective.

Becht’s full scope of Corrosion and Metallurgical Consulting includes:

  • Corrosion Control Documents (CCDs)
  • Integrity Operating Windows (IOWs)
  • HTHA Risk Assessments
  • Answer Man Corrosion/ Materials Support
  • Wet H2S cracking issues
  • Corrosion Reviews Supporting Risk Based Inspection (RBI)
  • Troubleshooting
  • Crude Evaluations
  • Support for Fitness for Service (FFS) assessments
  • Brittle Fracture Screening
  • Special Emphasis Programs, Such as Low Si Sulfidation Inspection Programs
  • Root Cause Failure Analysis (RCFA)
  • Expert Witness Support
  • 3rd Party Cold Eye Reviews
  • Training
  • Tiger Scoop Metal  Sampler
  • Site Detailed Mechanical Integrity Procedures
  • Hydroprocessing Reactor Effluent Air Cooler Systems Corrosion Investigation
  • Heater Tube Evaluation
  • NDE, materials properties, monitoring  
  • Emergency on-site support for unexpected shutdowns
  •  Risk-Based Inspection
  • Fire Damage Assessment 

Becht has particular expertise in the areas of HTHA Risk Assessments, Corrosion Control Documents and establishing Integrity Operating Windows. In addition, several clients have benefited from the Answer-Man Materials Support service to help with day-to-day issues.  Below are expansions on Becht's specific expertise:

High Temperature Hydrogen Attack (HTHA) Risk Assessments (Pono Method)

Due to several notable instances of HTHA that have fallen below the existing API 941 Nelson Curves, there is an industry wide focus on identifying at risk equipment and piping and replacing with more resistant alloys as soon as possible. Historically, the Nelson Curves have only considered temperature and the partial pressure of hydrogen in determining whether a piece of equipment is at risk for attack. The Pono method uses several additional real-world factors to adjust for realized operating conditions as well as the material in question’s actual realized properties at preventing HTHA. For more information specific to the Pono Method, please read THIS BLOG.

The Pono method has been accepted and utilized at a number of North American refineries. The method has helped in the prioritization of equipment replacement/upgrade. The simple, down-to-earth approach makes it easy to understand and implement. Feel free to contact for more information.

Corrosion Control Documents (CCDs)

Becht has extensive experience in leading corrosion reviews and preparing CCDs.  Our experts have experience with the different units and deep knowledge of the damage mechanisms at play.  Because of our experiences in owner-operator organizations, we have first-hand experience of both the problems and the solutions. Becht’s corrosion review process has been honed with years of practice to be efficient, cost effective, and provide a comprehensive document that is easy to use and maintain. Additionally, when requested by the client, Becht supplements the review team with process engineering subject matter experts, specific to the unit, to provide additional input to the review process.

Integrity Operating Windows (IOWs)

A key aspect of the CCD and the corrosion review is the establishment of IOWs.  Again, our experts have the hands-on experience and knowledge to establish safe but realistic envelopes as well as the appropriate procedures and responses, should a facility exceed the stated limits.  Our attention to detail and long-term perspective combine to deliver the best possible results. As with Corrosion Control Document preparation, Becht can supplement the team with process engineering subject matter experts.

Tiger Scoop Metal Sampler

The Becht Tiger Scoop is an innovative new tool for obtaining field samples from piping or vessels. Facilities often need to take samples for metallurgical analysis, mechanical testing, or for identifying damage.

In the past, this process has been difficult - requiring maintenance after the fact as well as 3rd party support to procure the sample. The Tiger Scoop is easy to use thus providing a sample in minutes. It can be easily braced into place but has the option for magnetic attachment.  The Tiger Scoop can be used on any inside diameter pipe or vessel greater than 18” and any size outside diameter pipe or vessel.  

The Tiger Scoop provides a quick, clean, continuous cut from start to finish. This, in most circumstances, eliminates the need for bothersome post grinding or weld repair. The Tiger Scoop is pneumatic powered, making it safer to use. Moreover, by eliminating an ignition source, it can be used in conditions previous samplers could not be operated safely.

Tiger Scoop is available for purchase or rent. 

Sampling services, if requested, are supplied by our partner IRISNDT.

Becht Central Engineering Materials Support

Given Becht's broad experiences across industries and materials, many of our experts are considered the "go to" resource in their industries.  This allows us to provide support to facilities without on-site support for materials and corrosion issues.  Whether it’s a quick question of which alloy to use, or whether PWHT is needed, or more complex issue, we standby to help answer questions almost on 24-7 basis by phone and e-mail for our clients that have signed up for this service, which costs nothing.  The client only gets charged when they use it.  

API and NACE and MTI Involvement

Our experts are active in the Codes and Standards Development activities, chairing or vice chairing numerous task groups (API 571, API 939-C, API 970, API 945, NACE SP0296, authoring API 934 (f, g, h) documents and MTI books.  This provides us with direct knowledge of industry issues and background to why the documents have certain recommendations.

Risk-Based Inspection

The API Inspection Codes were originally based on failure prevention and did not consider the consequences of failure or potential damage mechanisms.  Risk-based inspection (RBI) assessments result in an equipment risk ranking based on the probability of failure (a leak occurring) and the consequence associated with that leak.  Applied properly, RBI provides the benefit of increasing operating efficiencies and unit run lengths of process facilities while maintaining or reducing the current level of risk.

Traditional inspection codes and RPs (NBIC, API 510, etc.) give prescriptive or time-based requirements for inspection recommendations.  RBI provides the basis for making informed decisions on inspection frequency, the extent of inspection, and the most suitable type of NDE.  In most processing facilities, a large percent of the total risk for a process unit will be concentrated in a relatively small percentage of the equipment items.  These potential high-risk components may require greater attention through a revised inspection plan.  Focusing on these items can increase the ability to find expected damage while reducing unnecessary inspections on low risk items.

Becht Engineering’s Pono Division is highly experienced in implementation of risk-based inspection programs using multiple methodologies as well as producing corrosion control documents.  Becht has experienced RBI project managers who have managed over 100 RBI projects combined using multiple different methodologies throughout North America. Additionally, we have a large team of industry renowned Metallurgical/Corrosion experts who have over 200 years of combined experience within industry.  Our insight on the link between damage mechanisms and risk-based mechanical integrity makes Becht uniquely qualified for this type of work.
