Re: [MW:25222] Impact Testing requirement for welding procedure qualification

Dear Sir,

Impact testing requirement is not specified in the Client / Project Specification / data sheets / drawings for the welding procedure qualification except MDMT (-3 Degree Centigrade).

Code for fabrication is ASME B31.3 and I believe that the Client Specification or welding specification (of Client) and ASME B31.3 Code is sufficient to decide the impact testing rather than other requirements.  

Further, above 20 mm wall thickness we have already qualified welding procedure specification with impact testing.


With Kind Regards

The answer is the normal one – check what is required by applicable client specification, (or datasheets, notes on drawings or client clarifications) and code of practice. What is your application? Is it a pipeline (API rules probably apply) or piping (ASME IX rules probably apply). Minimum design temperatures may be dictated by blow down conditions rather than ambient conditions.

If the thickness us not higher than approx. 22 mm this material is impact test exempted. See ASME B31.3, table 323.2.2A curve B

Dear Experts,

 

We have the piping material spec. of API 5L Gr. B/ X52/X56 PSL piping materials, MDMT is -3 (North Kuwait) Degree centigrade and thickness ranging from 5 mm to 31 mm.

 

Please advice whether the impact testing is required to carried during PQT.

 

 

 

With Kind Regards

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...
