RT has got tolerance ( Some discontinuities are acceptable), so it is better to pressure leak test and RT is not substitute for leak test because while doing leak test some acceptable discontinuities may open which is hindrance in service

Dear Pratish

I am considering the situation you have is on piping weld joint ( it's not mentioned in your query). An hydrostatic leak test is only substituted with a service leak test when it is not practical to carry out one, the conditions for which are detailed in ASME B 31.3 para 354 Testing.   RT is not a substitute for a hydrostatic leak test.

Dear Prakash ,

 

RT is applicable if its a Golden joint .  Hydrotest / pneumatic is done to check the integrity of the whole line.( welds and material ) . There are services which has 100%RT and pneumatic test as well . So I don't think RT is a option.

Dear Members ,

 

Please clarify that whether in any circumstances we could substitute RT with pressure / any leak test for services where RT is been included as a inspection method.

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...
