Re: [MW:30730] BASE METAL THIKNESS FOR PQR

THANKS MASTER FROM YOUR ADVISE NOW ITS CLEAR 100/100 AS U MENTION BEFORE FROM YOUR EMAILS

Le jeudi 9 avril 2020 13:05:04 UTC+2, gerr...@yahoo.com a écrit :

Instead of being confused, first you should know what is your Job.

Then the design Code ASME B 31.4 or ASME B31.8

Snap shot provided below for you to decide.

See below requirement and snap shot of ASME B 31.8

Thanks & Regards

IM CONFUSED , NORMALLY WHAT I SHOULD TO USE ASME 9 OR API 1104

Le jeudi 9 avril 2020 07:02:56 UTC+2, gerr...@yahoo.com a écrit :
By below mail was based on API 1104 Code which considers yield strength as essential variable.

From your below mail I understand you are using ASME Sec.IX (correct me of I am wrong).

Acc to ASME Sec.IX one PQR is sufficient for API 5L X60 - X65 as they both fall under P1 Gr.2.

Acc to ASME Sec.IX thickness range qualified is 1.5mm to 15.84mm

tnx for your reply

So its mean that i should prepare two different Test coupon or what

and for the maximum thikness of base metal from QW 451.1 THEY MENTION THAT T QUALIFIED X 2 ITS MEAN 7.92 X2 = 15.84 mm

Le mercredi 8 avril 2020 13:52:38 UTC+2, gerr...@yahoo.com a écrit :
Considering Pipeline, API 1104 code was considered for below.

1. One PQR for X60 material
2. Another PQR for X65 material to be qualified'

If you qualify PQR on 6 inch wall thickness 7.92 mm then it qualifies from wall thickness 4.8mm to 19.1mm and no Limitation on Diameter

Thanks & Regards

Hello

i want to prepare a WPS for pipeline work with base metal API 5L X60 - X65 SMAW

for the test coupon i want to use 6" with thickness = 7.92 mm

want to know the minimum and maximum range for size and thickness used for the PQR

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...
