In every processing facility, you have feedstock and product that need to get from point A to point B. Piping is the vehicle that moves these liquids and gasses through a refinery or chemical processing plant. They can be made of steel, cast iron, copper, plastic, or other materials depending on the environment and materials being transported. Segments of pipe are often joined together using either bolted flanges or by welding pipes together. The major difference between piping and pipelines is that pipelines transport materials long distances between separate facilities or for distribution. Piping on the other hand is made to transport gasses and fluids, such as water or chemicals, within a single facility.[1]
There are several standards and recommended practices that apply to piping systems, including but not limited to:

Fixed equipment mechanical integrity (FEMI) failures are not caused by damage mechanisms; rather, they're caused due to failure to create, implement, and maintain adequate management systems to avoid failures. Nearly all failures that have occurred in our industry could have been avoided if these human systems were more robust and sustainable in providing the primary layers of protection for FEMI. |

Once the microwave inspection method was determined to be capable of providing reliable and meaningful inspection results for defects located on the exterior, interior, and interior surfaces of non-metallic components, potential industry applications were identified. Upon investigation, these applications were identified. Upon investigation, these applications proved to be numerous and varied in nature. This is the result of an apparent lack of reliable inspection techniques for many non-metallic components that are rapidly becoming materials of choice in many industries. |

During the past two years, a new High Resolution Gamma Ray Detector Array System to detect and measure small corrosion pits in real-time in the inservice piping in process industries, has been in development. This High Resolution Gamma Ray Detector Array can be substituted in place of the standard detector array in our ThruVU (TVU) system. The first High Resolution detector array has a total width of 1.00" and consists of 76 channels with 0.013" detector pitch. On the other hand, the detector pitch is 0.130" in the standard TVU detector array. So, the new High Resolution detector array can potentially provide a 10x better spatial resolution compared to the TVU standard detector array. |

We have been asked many times by existing and prospective users of PCMS (a computerized, inspection database management system), how many TMLs (Thickness Management Locations) should be installed per piping circuit. These inquiries must be addressed indirectly, because each specific site differs in its operation, mission and objectives. We firmly believe it is up to each site to make choices based upon their own circumstances. When pressed on the issue we have pointed toward a couple of papers published or generated within our User Community. While these provide cookbook methods, they do not encompass all the issues facing the User Group. Based upon the continuing questions in this area we decided to provide a review of the issues. |

This final issue on gusset problems will discuss why gussets are "stiffeners" rather than "strengtheners." The effective load bearing capacity of a member of given strength is based upon how large a cross-sectional area is carrying the load.

Last issue, in keeping with the evaluation that "gussets are stiffeners, not strengtheners," we discussed welding around the ends of the gusset plate instead of just along the sides in order to reduce the stress concentration. A further improvement in the gusset life can be obtained by welding it to a reinforcing plate and/or a fitting instead of directly to the pipe. |

A key to any piping evaluation program is to understand where problems can occur. Vibrating piping can propagate a crack relatively quickly.

For reason of economy, the hot reheat pipework in many US power plants is fabricated from seam-welded low chrome-moly carbon steel spools. Unlike girth butt welds, where the critical weldment microstructures can off-load stress to the stronger parent material, seam welds are subject to the full pressure hoop stress. A number of failures have occurred, some of which have been evidenced by fast fracture over extended lengths of the seam weld with a massive and violent steam release. |
