Examples of important Pressure Piping QA/QC documents

This document introduces some of the important QA/QC documents that are typically used in the industry. The aim is to explain their definition and purpose and also point out different types of information they provide to the reader.


List of Important Piping QC Documents


<!--[if !supportLists]-->·        <!--[endif]-->Inspection Test Plan (ITP)

<!--[if !supportLists]-->·        <!--[endif]-->Request for Information (RFI) /Non-Conformance Report (NCR)

<!--[if !supportLists]-->·        <!--[endif]-->Welder Qualifications

<!--[if !supportLists]-->·        <!--[endif]-->NDE Procedures/Qualifications/Results/Log

<!--[if !supportLists]-->·        <!--[endif]-->Weld Procedures(WPS/PQR),Weld Map/Weld Log

<!--[if !supportLists]-->·        <!--[endif]-->Pressure Test Procedures/Records

<!--[if !supportLists]-->·        <!--[endif]-->Calibration Records

<!--[if !supportLists]-->·        <!--[endif]-->Torque Procedures/Records/Maps

<!--[if !supportLists]-->·        <!--[endif]-->Material Test Report (MTR)

<!--[if !supportLists]-->·        <!--[endif]-->Line Designation Table (LDT)

<!--[if !supportLists]-->·        <!--[endif]-->P&IDs/As-built drawings

<!--[if !supportLists]-->·        <!--[endif]-->Punch Lists


Inspection Test Plan (ITP):


<!--[if !supportLists]-->·        <!--[endif]-->List of logical progression steps for inspections and tests

<!--[if !supportLists]-->·        <!--[endif]-->Must be approved by owner prior to start of construction.

<!--[if !supportLists]-->·        <!--[endif]-->Typically includes witness, review, hold, etc. points.

<!--[if !supportLists]-->·        <!--[endif]-->Signed by Contractor, Owner and ABSA if applicable


Material Test Report (MTR)


<!--[if !supportLists]-->·        <!--[endif]-->MTR certifies:

<!--[if !supportLists]-->·        <!--[endif]-->ASTM standards,

<!--[if !supportLists]-->·        <!--[endif]-->Applicable dimensions,

<!--[if !supportLists]-->·        <!--[endif]-->Physical and chemical specifications.

<!--[if !supportLists]-->·        <!--[endif]-->Provides material traceability through heat numbers

<!--[if !supportLists]-->·        <!--[endif]-->Tracking must be done upon receiving and during construction to ensure  right components are used

<!--[if !supportLists]-->·        <!--[endif]-->MTR can be useful for failure investigations


Line Designation Table (LDT)


<!--[if !supportLists]-->·        <!--[endif]-->Shows piping parameters such as line class, design pressure and temperature, test pressure, material, percent of NDE, etc.

<!--[if !supportLists]-->·        <!--[endif]-->Lists all the lines in the project and is a valuable and quick reference for QC activities


Piping Materials Classification


<!--[if !supportLists]-->·        <!--[endif]-->Indicates line class and associated service, material, corrosion allowance and design parameters limitations for that class

<!--[if !supportLists]-->·        <!--[endif]-->Lists description and rating of pipe, flanges, fittings, valves, etc. based on size of the item

<!--[if !supportLists]-->·        <!--[endif]-->Must be traceable to Bill of Material and LDT

Weld Map


<!--[if !supportLists]-->·        <!--[endif]-->Weld map shows welded joints, joint number and welder ID on an isometric drawing. It can include date, repair or cut-out and NDE information such as RT or MT report number.







Weld/NDE log


<!--[if !supportLists]-->·        <!--[endif]-->Lists welding procedures. heat numbers, drawing numbers, size, etc. 

<!--[if !supportLists]-->·        <!--[endif]-->Weld log and weld map need to correlate and be traceable with supporting documentation.

Welding Procedure Specification (WPS)


<!--[if !supportLists]-->·        <!--[endif]-->Provides direction for making sound welds

<!--[if !supportLists]-->·        <!--[endif]-->Shall be implemented to obtain required mechanical properties (Strength, hardness, etc.)


Torque Sheet


<!--[if !supportLists]-->·        <!--[endif]-->Documents torqueing of flanges

<!--[if !supportLists]-->·        <!--[endif]-->Specifies fit-up checklist and torque values required

<!--[if !supportLists]-->·        <!--[endif]-->States torqueing method and tool’s calibration information

<!--[if !supportLists]-->·        <!--[endif]-->Identifies flange and gasket ratings



Pressure test report


<!--[if !supportLists]-->·        <!--[endif]-->States code of construction, type of test and line information

<!--[if !supportLists]-->·        <!--[endif]-->Specifies test pressure and duration of hold time

<!--[if !supportLists]-->·        <!--[endif]-->shows gage calibration information and test medium

Shahin Shardi

Professional Bio of Shahin Shardi, P.Eng.
Materials Engineer
Welding and Pressure Equipment Inspector, QA/QC Specialist

Shahin Shardi is a Materials Engineer with experience in integrity management, inspection of pressure equipment, quality control/assurance of large scale oil and gas projects and welding inspection.
He stared his career in trades which helped him understand fundamentals of operation of a construction site and execution of large scale projects. This invaluable experience provided him with boots on the ground perspective of requirements of running a successful project and job site.  After obtaining an engineering degree from university of British Columbia, he started a career in asset integrity management for oil and gas facilities and inspection of pressure equipment in Alberta, Canada. He has been involved with numerus maintenance shutdowns at various facilities providing engineering support to the maintenance, operations and project personnel regarding selection, repair, maintenance, troubleshooting and long term reliability of equipment. In addition he has extensive experience in area of quality control and assurance of new construction activities in oil and gas industry. He has performed Owner’s Inspector and welding inspector roles in this area.
Shahin has extensively applied industry codes of constructions such as ASME Pressure Vessel Code (ASME VIII), Welding (ASME IX), Process Piping (ASME B31.3), Pipe Flanges (ASME B16.5) and various pressure equipment codes and standards. Familiarity with NDT techniques like magnetic particle, liquid penetrant, eddy current, ultrasonic and digital radiography is another valuable knowledge base gained during various projects.
Some of his industry certificates are CWB Level 2 Certified Welding Inspector, API 510 Pressure Vessel Inspector, Alberta ABSA In-Service Pressure Vessel Inspector and Saskatchewan TSASK Pressure Equipment Inspector. Shahin is a professional member of Association of Professional Engineers and Geoscientists of Alberta
