RE: [MW:5287] Process pipe work

You have to follow the construction code.

Dear Mr. Limesh
Welcome to the forum.
ASME materials are adopted in sec IIA/B, which are generally used in BPV code. B31.3 allowable stresses are listed for ASTM materials. If you select ASTM materials, pl check applicable year of edition&addenda, equivalent ASME listed materials can be found on respective code with year of edition/addenda.
Similarly, others like API (American Petroleum Institute) can be found in API 5L standard. These are similar to ASTM/ASME, but neither is superior to other.
No restrictions to use these materials as long as your designer select them based on their allowable stresses.

Subject: [MW:5271] Process pipe work

Dear All,

I am a young guy having strong desire to learn something in welding.I
would like to clear some of my doubts through this forum.Please don't
curse me or ignore my query if you feel it foolish as I don't have
much experience like my seniors.

Dear all,

I am working in a small process pipe work based on ASME B31.3
code.Here which material code we have to review,ASTM series or ASME
BPV SEC II Part A (Ferrous) Part B (Non ferrous)?As far as I am
concerned both looks same !!! If any dispute comeup which one has the
upperhand(Has the capability to supercedes the other). More over I
couldn't find some of the materials in ASTM and BPV SEC II Part A or
B. But they are listed in ASME SEC IX (Eg. API 5L grades).Is there
any restrictions to use these materials for process pipe work?

Thanks and regards

Limesh

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...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
