Re: [MW:13326] Identification of thickness on Radiography films.

Dear RK Vichare.
 
For me this is more an ethical issue than anything else. i know it is difficult as an interpretor to find thickness from the document everytime, but RT film adresses the joint correctly with joint no. and drawing no., it is possible to find out.
 
if it was me i would rather struggle onetime and ask the contractor to include thickness next time during RT, rather than rejecting the films.
 
I believe it is unethical to reject films like this as we all know that RT is a dangerous job, no matter the technician is geting paid but its still dangerous for him so try to minimise RT as much as possible also it is waste of money.
 
As an interpretor we are trusting the contractor based on proffesional ethics, because if i ask you, how sure are you about the rt films presented to you are from the correct/right joint?. yes it is possible to find out but do you always cross check that?( its also a difficult job but we trust the contractor on that most of the time.)
 
so thats what i will do, ask the contractor to include thickness next time around. if he dont do it and comes up with some codes to support him, i ll take things personally from then with him.:)
 
thank you

Dear Mr.Jean Station,
Thanks, I know it is not in any code (i.e.Sec-V Artical-2) or any other code but as far as for interpretor it is very difficut to review numbers of Radiography films & identify the IQI selection whether it is correct or wrong. If ready reference of thickness on Radiography films it is easear to interpret films in time . As far as my experience till date there was no any issue of indicate thickness on RT Films but; may be it is not confirm in any code; vendor/techiicians may take dis-advantage for the same and might have a change to use wrong IQI which may not be possible to controll quaity of Radiography  by surveyor/interpretor  because every time it is not possible to serch each documents for find out actual/thickness range used for Radiography.

Please go through my below mail again  and advise.

RK Vichare

I don't know of any Code that mandates putting thickness on the actual radiograph, although since there are many codes, there may be. The A.I.'s /third parties I've always dealt with know to look at the prints/ISO's, etc.  There is usually a report that indicates the thickness.  It is up the third party, A.I. to read the report to find information regarding the radiograph and from there to ascertain whether correct IQI has been used.  If we have room on the I.D. we will put the thickness on the report but if not, all information is on the report.

Dear Experts,

During Interpreting Radiography films at one of my vendor's works, I observed that, there is no identification /indicate thickness of job on film so I rejected the film. As far as generally everyone related field experience persons are know unless identification of thickness on film it is very difficult to know which penetrameter to be used but my vendor is arguing for the same. According to him one of "Level III" person insisit them there is no need to mentioned thickness in Radiography films and it sufficient if it indicate in Radiography interpretion report.
Suppose in piping number of joints/piping spools  are comming  with verious thickness in same report in such case it is possible to identify required penetrameter ? My anser is no, each Radiography films must be indicat thickness of joint/job.  Requested to suggest/advise.

Sincerely yours,
RK Vichare

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...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

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, ...
