[MW:23094] Can the certificate type 3.1 re-certified by 3rd party inspection?

Dear. All.
I would like to know whether the piep can be re-certified as type 3.2 with certificate issued by independence agency.
 
When the 3.2 certificate type is requested the manufacturing, however, mill(Pipe) has already prepared a 3.1 type and delivered document/material to plant manufacturer.

In this case, I'd like to know that plant manufacturer can use this pipe?

Of cause never use.

 

Normally, whenever we met above case, we have tested the mechanical properties, chemical composition and special requirement for this project under 3 party's witness. (LR, TUV & SGS)

And then, we can receive the certificate type 3.2 issued by witnessed inspection agency.(LR, TUV & SGS)

Actually, I have been maintaining the certificate 3.2 type for above situation and the certi. has been issued by TUV.

 

However, someone told me that upgrading the certificate from 3.1 to 3.2 type never do, although the tests have been carried out under 3 party's witness after delivered from Mill Maker.

They are insisting that the certificate is only 3.1type + witness the test by 3party.

 

Because of following context,

3.2 type is document prepared by both MFG and 3rd party agency.

 

Please let me know that in this case, the 3.2 type certificate can be issued by 3 party agency or not?

 

4.2 Inspection certificate 3.2 "type 3.2"

Document prepared by both the manufacturer's authorized inspection representative, independent of the manufacturing department and either the purchaser's authorized inspection representative or the inspector designated by the official regulations and in which they declare that the products supplied are in compliance with the requirements of the order and in which test results are supplied.

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, ...
