Inspection, Evaluation and Repair of Process Plant Equipment and Connected Piping

Overview:

Introduction:

Petroleum refineries, petrochemical, and process plants have hundreds of pieces of equipment and thousands of meters of piping that handle hazardous and corrosive fluids and operate a wide range of temperatures and pressures. Plant integrity and reliability can only be achieved if this equipment and connected piping are designed properly and they remain fit for continued service between scheduled turnarounds.

The design and fabrication of process equipment and piping systems are carried out by industry codes and standards. Fabrication and welding processes are subjected to defined examinations and inspections to ensure that any deficiencies found are resolved to meet the acceptance criteria of the respective codes.

Once the new equipment and piping are put in service, they get exposed to the process fluids and start to undergo deterioration such as corrosion at various rates depending on the materials of construction and service conditions. It is therefore essential to know their current condition and the degradation rate so that appropriate repairs and maintenance can be carried out on time to prevent failures. Effective inspection and evaluation of the inspection data are vital for this purpose. The integrity of the plant cannot be achieved without effective inspection.

Regular and reliable inspections are an integral part of any effective industrial plant maintenance program. The success of such a program relies greatly on the Non-Destructive Inspection (NDT or NDE or NDI) techniques used. Non-destructive inspection (NDT) techniques detect flaws that can cause potential failure in the future. This way, NDT provides information on the integrity of the pipeline as well as a measure of its current safety margin. Hence, it is important to understand the scope and limitations of the common and advanced NDE tools that are available to maximize the effectiveness of each of the scheduled inspection activities.

Furthermore, in today’s competitive environment plant operators need to reduce maintenance costs by minimizing downtime. Effective inspection contributes significantly to this objective

Conference Objectives:

At the end of this conference the participants will be able to:

  • Understand the damage and degradation mechanisms that affect process equipment and piping and progressively adversely affect their condition and fitness for continued service.
  • Understand that effective inspection is the backbone of plant integrity and that it has a significant impact on EHS and the financial performance of the company
  • Increase the awareness of industry codes and best practices related to inspection, repair, and alteration of process equipment and piping including ASME BPVC and various API codes, standards, and recommended practices.
  • Provide a sound and concise coverage of fitness-for-service assessment methodologies and API/ASME FFS standards to enable making run/repair/replace decisions about the damaged equipment/piping
  • Cover the main industry codes and practices for repairs and alterations to achieve business focused repairs and lower maintenance costs
