    The ASME PCC continues to meet four times per year during ASME Code Week. The last meeting was on December 9, 1996. Over 50 members and visitors were in attendance. At that meeting, both subcommittees (Flaw Evaluation S/C and Inspection Planning S/C) continued to work on drafting detailed outlines of what each S/C expected to cover in its respective document.

    Damage of carbon steel pressure vessels due to various in-service damage mechanisms continues to be a serious concern in the refining and petrochemical industries. A survey conducted in 1990 by the NACE T-8-16 Work Group to determine the nature and extent of cracking problems in wet H2S refinery environments showed that there was insufficient information reported about the type of cracking found to correlate cracking incidence with cracking mechanisms. Most of the inspections for cracking reported were detected during internal inspection using Wet Fluorescent Magnetic Particle Testing (WFMPT). As a result, it was concluded that in addition to the service related cracks reported, a number of "cracks" detected were the result of original fabrication, repair or alteration of the pressure vessels.

    In the Jan/Feb issue of the IJ, I mentioned how important the Management of Change (MOC) process is when it comes to maintaining safe, leak-free piping systems; stating that we in the inspection business cannot do it alone; that is, we taint the integrity of piping systems without a lot of help from operating personnel and operations support engineers.

    Shortly after World War II, the FRP industry expanded rapidly into many areas. Chemical tanks were first fabricated in the 1950s. A comprehensive standard was needed and in 1969 a consensus standard was issued by the National Bureau of Standards: NBS PS 15-69 "Custom Contact-Molded Reinforced-Polyester Chemical-Resistant Process Equipment."

    If you perform any type of inspection, plan or prioritize inspection, replacement or design of equipment in HF service you may be interested in the following NACE international resource, NACE Technical Committee report 5A171, "Materials for Receiving, Handling, and Storing Hydrofluoric Acid."

    At recent meetings with refinery groups, a tool that is typically used during the design and construction of refinery units was presented. Then, brainstorming took place on ways this tool could be used in the refineries for day-to-day operation, maintenance, and other activities.

    Engineering, Procurement and Construction (EP&C) companies have a monumental task to maintain accurate NDE records on major new construction projects. Fluor Daniel has developed and put in use over the last several years a database program for tracking pipe welds and the NDE associated with them.

    Back before I became a consultant in 1962, I was employed by TransCo. My boss had a number of very descriptive expressions for commonly encountered problem conditions with reciprocating compressors. One of them that I have always appreciated over the previous 30 plus years was his term for pendulum action of a large unsupported mass on the end of a vibrating pipe. He called it "a billiard ball on the end of a fly rod." You avid fishermen will appreciate that one.

    Continuing with the theme "a billiard ball on the end of a fly rod," this month we will look at one alternative to mounting a heavy block valve on a small diameter nipple in vibrating conditions. A popular situation is where the purpose of the branch is to feed process control metering, which is generally located some distance from the product flow line.

    In a past issue, we discussed one solution to the instrument line block valve pendulum problem. This was where the valve assembly can be mounted remotely from the vibrating product line, such as at-grade. This issue covers two possibilities where the valves need to remain close to the vibrating line.

    This is the second in a series of articles on piping inspection. In the last article, I enumerated four inspection issues that I believe contribute to inadequate piping mechanical integrity in the hydrocarbon process industry.

    It's probably more important to those of us who don't have a brain tumor. Unfortunately, it's precisely because piping inspection is not neurosurgery that it's often done poorly, which can lead to significant impacts on process unit reliability, or worse, a catastrophic event, where people can get hurt.

    This is the fourth in a series of articles on piping inspection that I'm writing for the Journal. One of the previous ones dealt with improving thickness data taking accuracy with digital ultrasonic methods. This article is a "sister article" that deals with improving the accuracy of profile radiographic inspection techniques, also called isotope radiography, wall shots, or tangential radiographic inspection.

    Regulatory requirements such as OSHA 1910, industry codes and practices coupled with an international drive for more cost-effective preventative maintenance are leading the industry toward data information management systems to assist in organizing and prioritizing preventive maintenance strategies. This shift coincides with the movement toward a risk-based inspection approach to plant condition management. This approach ranks units or individual equipment according to criticality or risk, allowing inspection efforts to be focused where they can have the greatest effect in risk reduction. There are a number of points to bear in mind when planning to implement a plant condition management system.

    This task though tedious and exasperating is a key part of the operation. Plant personnel often find ingenious uses and filing systems for key data such as UW 1 forms. The more remote the plant site is, the more extraordinary the hiding places. In addition, the adage "garbage in = garbage out" keenly applies. To avoid this concern, it is vital to quality assurance check the data prior to input.

    The API Commitment on Refinery Equipment (CRE) has chartered a task group to develop an API recommended practice (RP 580), which will detail all the vital aspects of Risk-Based Inspection. This standard will not detail or propose any one specific RBI procedure, but will detail all the important aspects, issues and concerns that a valid RBI procedure could and/or should consider.

    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 of internal pressure and through-wall thermal stresses generated by operational transients. The typical composition for alloys for reforming service is 25/20 Cr/Ni with the generic reference HK40.

    AIM systems should ensure that the your facility’s MI software is accurately performing the calculations needed to calculate minimum thickness, long/short term corrosion rates and remaining life used to predict future inspection intervals. They should evaluate your MI software’s basic design and corrosion monitoring variables.

    Case 1: Fuel Gas to Boilers in boiler house: in 1992 two flanges were installed for installation of knock blinds. No degassing was completed. Both welds were radiographed and noted as acceptable. Case 2: Alky Unit Flare Header: No degassing completed in 1993 on multiple tie-ins. All of these tie-ins were radiographed and noted as acceptable. Case 3: Alky Unit flare Header: No degassing completed in 1993 on multiple tie-ins, all of these tie-ins were radiographed and noted as acceptable.

    The amount of serious questions regarding the various technology options for implementing an effective RBI program is growing by leaps and bounds. I, for one, have seen many forms of what various organizations refer to as RBI. Remember that there are to the Risk equation, i.e. likelihood or probability of failure and consequence of failure. The effectiveness of the RBI tool is highly dependent upon algorithm design, especially parametric considerations and their relative effect on one another and your objectives.

    AWS, in conjunction with the Edison Welding Institute and The Welding Institute, are offering a program for the certification of NDE operators. The certification follows the operators. Areas for certification are PT (penetrant testing), MT (magnetic particle testing), UT (ultrasonic testing), and RI (radiographic interpretation).
