RE: [MW:31232] Combination of PQRs

Kiran,

As I said before, HIC Testing is not MANDATED by ASME Sec-IX or any API, NACE specification. Does the project specification call for HIC testing during PQR qualification stage?  HIC testing is typically mandated for raw materials , e.g. plates, pipe, line pipes etc. Look at NACE TM-0284 . What's the component pressure vessel or  line pipe?

If your organization has done HIC testing  on PQR  coupons, you may use this result as a supplementary information over and above the PQR qualified with PWHT. Combination of PQR is allowed in ASME Sec-IX

Hope it clarifies you doubt. Also please scan and share your project requirements?

 

Thanks.

Dear Sir,

 

Thanks for your response.

 

Sorry I am not able to understand your answer.

 

You mean that PQR can be separately included, there will be no issues right. 

 

I will explain to you in detail.

 

I have one WPS and with two PQR's.

 

one PQR with PWHT and second PQR we prepared an additional test coupon for the HIC test only.

 

And HIC  PQR has tested accordingly NACE MR 103 , API(RP-582), and NACE TM -0284, but in PQR we have not conducted mechanical, PWHT, and other tests.

 

If we have two PQR , so according to ASME Sec.IX we have to combine both PQR in WPS, with all essential variables.  

 

Please give me your response immediately, because my document is under hold.

 

Thanks 

Kiran

Hello KK,

HIC testing usually does not apply for   procedure qualification according to Sec-IX or even  as per oil and gas industry standards, say NACE MR 103 , API(RP-582). Common industry document for HIC testing is NACE TM -0284, which calls for HIC testing on parent metals, plates/ pipes etc.

 

How does this idea of HIC testing originate? Is it possible for you to share any specific or relevant document?

 

Thanks.

Hi,

 

Yes, Piping requirements.

 

SA 516 gr 60/70. and according to ASME Sec.IX and ASME B31.3.

The main PQR is qualified with PWHT, but not HIC tested.

And I have additional PQR with HIC tested, but not qualified with PWHT, and no other lab test reports like a mechanical test, bend test, and hardness test report, shall I combined this PQR to my WPS.

 

Please looking you feedback.

Thanks 

Kiran

Hi,

 

Please specify the material grade and the design code. 

 

As you have mentioned Line class, I presume you are talking about piping .

Hi Experts,

 

"Good Morning"

 

According to my line classes, I required NACE+HIC+PWHT Wet H2 services.

What is the test shall be conducted according to the standard to meet the requirements?

 

I have one PQR with NACE+PWHT+Wet H2S services, but not HIC test.

In addition, I have qualified one HIC tested PQR without PWHT no other lab test certificates, shall I combined this PQR to the above requirements( NACE+HIC+PWHT+wet H2S).

For your information, the HIC test is an additional requirement of our specifications.

Please looking your feedback on my above query.

 

Thanks and Regards

Kiran

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...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
