Re: [MW:11077] Query regarding Flanges

By Materials & Welding
Dear Mr. Ilangkuran,

Before concluding further, check up service condition, process fluid, last but not least, root cause and solution for improper support for WNRF.  

F 316L is compitable to weld with 304L ( pipe material), with proper consumable.


With Best Regards,

[MW:11074] Query regarding Flanges





Dear experts,
 
                Our existing weldneck flange butt weld failed due to improper support provided and we decided to replace it. Now the existing one is SA182 Type F304L due to unavailability of this we decide to replace it with readily available SA182 Type  316L. PNO & GROUP NO remain same for both the flanges as per section IX.
 
 Is it compatible in terms of weldability and its intend service or what will be the consequences if its welded? or should we use only type F304L?
 
Can somebody explain me?
 
Regards
Ilangkumaran

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

By Materials & Welding
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

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...
