Re: [MW:34960] PQR AWS D1.1

Dear,

Certainly, according to AWS D1.1, the qualification of Procedure Qualification Record (PQR) for pipes is indeed possible. The relevant clause in AWS D1.1 that addresses this is typically Clause 3, "Qualification." This clause outlines the requirements and procedures for qualifying welding procedures, including those for pipes.

To qualify a PQR for pipe welding under AWS D1.1, you would need to follow the guidelines outlined in Clause 3, which includes considerations for thickness, diameter, and testing requirements.

Here's a summary of what AWS D1.1 typically requires for qualifying pipe PQRs:

Thickness Range: Specify the range of pipe thicknesses for which you intend to qualify the procedure. AWS D1.1 usually provides guidelines for the minimum and maximum thicknesses that can be included in the qualification.
Diameter Range: Similar to thickness, specify the range of pipe diameters for which you intend to qualify the procedure. This may vary based on project requirements and industry standards.
Testing Requirements: AWS D1.1 typically specifies the testing requirements for qualifying welding procedures. This may include various non-destructive testing (NDT) methods such as ultrasonic testing (UT), radiographic testing (RT), magnetic particle testing (MT), or dye penetrant testing (PT), depending on the specific welding process and material.

To provide specific qualification ranges for thickness, diameter, and testing, it's important to refer directly to the AWS D1.1 code for the most up-to-date and accurate information. Additionally, consulting with a qualified welding engineer or inspector can help ensure that the qualification process aligns with the requirements of AWS D1.1 and any other applicable codes and standards.

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

Hi, You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this. Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime. Again, these simulated no. Of cycles shall be specified in MTC. The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case). One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example. In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change. Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
