January/February 2001 Inspectioneering JournalBy John Reynolds at Intertek
Part 5 of this article continues to outline the 101 essential elements that need to be in place, and functioning well, to effectively and efficiently, preserve and protect the reliability and integrity of pressure equipment (vessels, exchangers, furnaces, boilers, piping, tanks, relief systems) in the refining, gas processing and petrochemical industry.

The use of contractor inspectors for turnarounds has increased in recent years. Mergers with reductions in staff personnel for major oil and chemical companies have fueled this growth. Still, we hear "horror" stories about problems that occur during turnarounds involving contractor inspectors.

The use of engineering critical assessment (ECA)of "fitness for service", for the evaluation of flaws and local wall thinning in pressure vessels is receiving a lot of attention in the petrochemical and utility industries. A rigorous methodology based on fracture mechanics and accurate flaw sizing can be used to assess the risk of operation of a damaged vessel by predicting the amount of damage that can lead to premature failure.

July/August 2001 Inspectioneering JournalBy Greg Alvarado at Inspectioneering Journal
We've come a long way since my introduction to plant inspection processes in 1975 and certainly since the industrial revolution in the late 1800's. As I recall from history class it was the intent of the wealthy industrialist to make money, plain and simple. Safety and environmental responsibility were not the primary concerns, in some cases not concerns at all! Hence, for safety's sake, terms like "sweatshops" were coined. This was to connote factories and textile mills where human beings, often times young children worked, in poor conditions.

September/October 2001 Inspectioneering JournalBy Greg Alvarado at Inspectioneering Journal
In part 1 we covered: - Evolution of the emergence of advanced NDE - External and internal motivators to develop more effective inspection programs - Risk based approaches - Sources of industry reference materials - Setting the Course - Why Inspect - Metrics for inspection program progress - Role of Risk Based Inspection I will now cover some of the remaining key aspects in assuring healthy evolution of the equipment integrity process.

Follow-Up: Status of the Texas PE Board Initiative on "Guidelines for Minimum Laboratory and Staff Qualifications for Nondestructive Testing Services"May/June 2001 Inspectioneering JournalBy Russel T. Mack at National Association of Inspection Companies (NAIC)
In a previous edition of Inspectioneering Journal, we alerted readers to a proposal to the Texas PE Board that would require NDT inspector certification according to CP-189 (instead of SNT-TC-1A)-which would effectively eliminate limited-scope certifications. The proposal would also require that every inspection service company have on full-time staff-a registered PE who is also an ASNT-certified NDT Level-III.

March/April 2001 Inspectioneering JournalBy Gerrit M. Buchheim, P.E. at Becht Engineering Co., Inc.
With the publication of API RP 579 For Fitness-For-Service and the planned publication of API RP 580 for Risk Based Inspection in 2001, these technologies will find increasing application in maintenance and inspection planning.

July/August 2001 Inspectioneering JournalBy Greg Alvarado at Inspectioneering Journal
Inspectioneering caught up with Dave Wang at the American Petroleum Institute’s (API) Spring 2001 Refining meeting in Atlanta, Georgia. We spent some time, near the pool at a break between meetings, discussing Dave’s background, experiences and the future of NDE from his perspective.

Nondestructive Assessment of Mechanical Property Loss of SA-516-70 Steel due to Hydrogen Induced CrackingSeptember/October 2001 Inspectioneering JournalBy W. David Wang at Shell Global Solutions
Hydrogen-induced cracking is a damage mechanism commonly observed in the petroleum refining industry [1, 2]. The damage appears as laminar cracks and blisters, which can link up in the through-wall direction to form stepwise cracking.

A typical risk based inspection (RBI) analysis should include past inspection results, tempered by confidence in those results. For example, API's (American Petroleum Institute) RBI methodology and software when calculating the likelihood of failure side of the risk equation asks for past inspection histories. This includes dates of past inspections for potential damage mechanisms, the effectiveness of those inspection techniques to find the anticipated damage and amounts of coverage. Via this logic, the program constructs a factor to represent the probable damage population scatter band and multiplies this times the entered corrosion rates, cracking susceptibilities or bulk damage rates.

March/April 2001 Inspectioneering JournalBy Deal Moore at NDE Seals, Inc.
Determination of the mechanical integrity of pipe and equipment in US process industries has evolved from day to day business to federal mandate (OSHA 1901.119) to a part of industry best practice. Insulated pipe and equipment pose specific challenges for the examination effort. This article is an attempt to review the regulations that are driving these efforts and the innovations designed to address these challenges. Understanding both will enhance the value added services offered by the insulation industry.
