RE: [MW:11591] FCAW using restriction in offshore applications

By Materials & Welding
Hi Elshan,
 
To the best of my knowledge FCAW/GMAW-S is accepted for fabrication of offshore structures with certain restrictions. Certain information would be helpful:-
  • The design code
  • Additional specifications and requirements by certification bodies, e.g ABS, DNV, LR etc
  • The materials to be welded by FCAW process.
  • Welding consumable proposed.
Below are the examples of accepted welding processes from  DNV-OS-C401-FABRICATION AND TESTING OF OFFSHORE STRUCTURES.
 
Appreciating your reply.
 
Thanks.

 Welding processes

Welding may be performed with the following processes unless otherwise specified:

— manual metal arc welding (metal arc welding with covered electrode)

— self-shielded tubular-cored arc welding

—  submerged arc welding

—  submerged arc welding with strip electrode

—  metal inert gas welding, (MIG) welding

—  metal active gas welding, (MAG) welding

—  tubular-cored metal arc welding with active gas shield-FCAW

—  tubular-cored metal arc welding with inert gas shield- FCAW (Mixed /Inert GAS)

—  gas tungsten arc welding, (GTAW)

— plasma arc welding.

I don't think there is any restrictions on the use of FCAW on offshore applications. We did use FCAW when I was working for Sarawak Shell Berhad (SSB) on a 316L Cladded pipepine, unless it is specifically stated on the project requirement that you can not use FCAW.

Hi friends,
 
I would like to find an answer if the FCAW is restriced to use in offshore applications as welding process even if the correct wire is used for to be welded materials?
 
Best regards,
Elshan.

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...

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

By Materials & Welding
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, ...
