[MW:19612] RE: 19588] A890 duplex steel casting crack repair.

Hi Abhimanyu,

Attached is the data sheet on A 890 3A alloy. The properties are the best with matching consumables. E-2553 or E-2593 are the choices. As this alloy contains high"C" HAZ hardness and could be an issue.

Crack repair should be done with due care, and PWHT (Soln Anneal should be done ) needs to be done as required. Clause S33 of ASTM A-890 is appropriate for repair welding of this alloy.

E/ER 2553 or 2593 weld metal contains lesser "C" than base metal, which is critical for any repair welding. A good consumable manufacturer could be of help. Many of them are present in the forum.

Hope this would help you.

Thanks

Grade is 3A

What's the specification/grade of DSS casting to be repaired. You need to specify that. The filler/ electrode used should match the chemical composition of the grade to be repaired.

It's advisable to perform "Soln Anneal" following repair, as per A-890.

Appreciate your response.

Dear sir,

Can any one provide WPS for crack repair in A890 duplex steel casting.

IS Filler ER 2593 is OK for doing welding.

Thanks in advance.

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, ...
