Re: [MW:33633] Missing Material Certificate of Existing Line

By Materials & Welding
Dear Hasanov,

                           Spark direct reading spectrum (OES) & Inductively coupled plasma emission spectrometry (ICP-OES)-ASTM E 415.

The above two methods will serve your purpose.

Thanks,

Kind Regards,

G.Gughan

Thanks Mr.Gerald,
Do you known labs which is performing tests with respective methods?

First identify and check with the Lab how much grams of Fillings (using manual File on Pipe external surface) are required and sometimes even Lab will come and collect the Fillings. What is your Pipe Thickness and obtain operator permission to remove 0.5mm or 1mm from the live line surface to collect fillings. Normally spectroscopy involves an arc and not advisable on live line and X-Ray Fluoroscopy may be permitted but you cannot determine carbon content and the only viable option is to collect fillings.

Thanks & Regards

Mr Gerald,
During shut down (welding our TEEs to live line) we will have time only for welding. 
So, I have to have a proper qualified WPS on my hands prior to shut down.
Operator of live lines is not able to provide certificates and live line's were manufactured according to GOST standard (Even not  to API or ASME).

I believe from your mail that you are not going for Hot Tapping that means the Line has to be shut down for welding with TEE.

I suppose you have to plan during shut down all these activities.

Also check with the operator incharge whether any filling (use File) from external surface of the Live line possible without reducing much thickness

Thanks & Regards

Mr Gerald,
Problem is that, line is live an now we can to go for shut down and taking a test coupons/samples is not possible.

To find the exact chemical composition of existing line, perform volumetric analysis (lab test) from the Fillings collected from existing line. (check with Chemical testing lab the exact grams needed).

Thanks & Regards

there will not be hot tapping - there will be installed "TEE" and new line will connect with existing through the "TEE"

Hi
Are you going to do hot tapping on the existing pipeline? 

Refer previously used materials documents from Client or refer the data sheet / material requirements of FEED. 

And consult the Operation and Maintenance team of Client. As a QA QC  do not have authorization to change or replace any materials.

Dear All,

We have to weld our new fabricated pipeline to existing live line. (welding code is 1104).

Unfortunately,  we do not have a certificates of existing line. and it is not possible to perform shutdown to take a test coupons and perform chemical analysis and mechanical tests to identify grade of materials.

All knows that, existing line's material is Carbon steel but exact Yield and tensile Strength and Chemical prosperities are unknown. (our new fabricated pipeline is also Carbon steel.

Could you please advise me what can we do in this condition?



Regards,
Ilkin HASANOV

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

By Materials & Welding
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

By Materials & Welding
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, ...
