[MODULE 11 PART 1] ASME PCC-2 (2018) - API 570 STUDY GUIDE - Introduction

 ASME PCC-2–2018

Repair of Pressure Equipment and Piping

INRODUCTION

Another code is added for the exam of API 570 Piping Inspector Exam. This code will be effected from the February 2023 exam window.

Even though it is not needed, we will have a look at the scope of the standard. This will give a general idea about why the standard is generated and where we can apply this standard.

SCOPE

1. This is a standard not a code.
2. This standard covers the methods for repair of equipment, piping, pipelines, and associated ancillary equipment
3. This standard is applicable to Equipment and piping within the scope of ASME Pressure Technology - Codes and Standards includes piping (including pipelines) and piping components (such as valves), boilers, pressure vessels (including heat exchangers), and storage tanks.
4. These repair methods include relevant design, fabrication, examination, and testing practices and may be temporary or permanent, depending on the circumstances.
5. Inspection and flaw evaluation methods are not covered in this Standard

From the above we can understand that this is not a stand alone standard. When an inspection has detected a flaw, the repair can be done based on this standard. 

It is important to note that the standard is applicable for In Service Equipment only.

This standard is organized as 5 parts. In that we have to study,

Part 2 : covers repair methods and techniques that include the use of welding, brazing, soldering, or other methods involving metal deposit.

Article 201: Butt-Welded Insert Plates in Pressure Components

Article 206: Full Encirclement Steel Reinforcing Sleeves for Piping

Article 209: Alternatives to Postweld Heat Treatment

Article 210: In-Service Welding on to Carbon Steel Pressure Components or Pipelines

Mandatory Appendix 210-I : In-Service Welding Procedure/Welder Performance Qualification Setup

Article 211: Weld Buildup, Weld Overlay, and Clad Restoration

Article 212: Fillet Welded Patches

Part 3 : covers mechanical repairs, with or without sealant, such as bolted clamps or fixtures and includes all repair methods not covered in Part 2 or Part 4.

Article 304: Flaw Excavation and Weld Repair

Mandatory Appendix 304-I : Metal Removal Process

Article 305: Flange Repair and Conversion

Article 306: Mechanical Clamp Repair

Part 5 : covers examination and testing methods and techniques.

Article 501: Pressure and Tightness of Piping and Equipment

Mandatory Appendix 501-I : Pressure/Leak Testing

Mandatory Appendix 501-II : Stored Energy Calculations for Pneumatic Pressure Test

Mandatory Appendix 501-III : Safe Distance Calculations for Pneumatic Pressure Test

Mandatory Appendix 501-IV : Risk Evaluation Considerations for Pneumatic Pressure Test

Article 502: Nondestructive Examination in Lieu of Pressure Testing for Repairs and Alternations

Mandatory Appendix 502-I : Comparison of Selected NDE Methods

Only the above mentioned sections from PCC-2 are included on the exam

In the body of knowledge it is written that "The examination will cover each referenced Article and its Appendices" so the Mandatory appendix of the articles are also to be studied. So we have to study 210-I, 304-I, 501-I,II,III,IV and 502-I.

 It is to be noted that many of the topics covered here are mentioned in the API 570 and ASME B 31.3 also. So we will try to do a comparative study so that it will be easy to remember the points in each of the standard/code.

We will cover each Part and its mandatory appendix from the next blog of this series.
