Re: [MW:26216] CRA Clad pipeline welding

Re: [MW:26216] CRA Clad pipeline welding - SAES-W-019

Hi Neilashkumar

Thanks for the reply.

The application is girth welding of roll bonded & SAWL CRA-clad line pipe, not weld over lay.

It is agreed that API 1104 is normally applicable for cross country pipeline with carbon steel line pipes.

But the gas transmission pipelines are designed to ASME B31.8 which is specifying to use API 1104 for welding, but SAES-W-019 is specifying to use ASME Sec IX. Of course, Client specifications shall take precedence, but the rationale of applying ASME Sec IX is not clear.

Krishna,

Below interpretation is not clear, can you please share more details on CRA overlay that you intend to qualify? So that I can help u to explain in better way.
SAES W 019 for CRA Girth weld
API 1104 for cross country pipeline,

Deal all

Pipeline design code is ASME B31.8 that is specifying to use API 1104 for gas transmission pipelines.

But, SAES-W-019 specifying to use ASME Section IX,

Do anyone received approval to use of API 1104 for CRA-Clad pipeline welding,

Thanking you

Krishna

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...
