Re: [MW:34958] Materials

Dear,

Carbon steel is often used in boiler feed water lines due to its cost-effectiveness and suitability for high-pressure, high-temperature applications. However, the choice between carbon steel and stainless steel (SS) depends on several factors:

Cost: Carbon steel is generally more affordable than stainless steel, making it a preferred choice for large-scale projects where cost is a significant consideration.
Strength and Durability: Carbon steel is known for its strength and durability, especially in high-pressure environments. It can withstand the stresses associated with boiler feed water systems.
Corrosion Resistance: While stainless steel (SS) offers superior corrosion resistance compared to carbon steel, the feed water quality and operating conditions play a crucial role. If the feed water is properly treated and maintained within acceptable parameters, carbon steel can perform adequately without significant corrosion issues.
Compatibility: Depending on the specific composition of the feed water (e.g., pH levels, dissolved oxygen content), carbon steel may be sufficiently compatible. However, in cases where the feed water contains corrosive elements or impurities, stainless steel might be a better choice due to its higher corrosion resistance.
Maintenance Requirements: Stainless steel generally requires less maintenance compared to carbon steel because of its superior corrosion resistance. However, carbon steel can still be effectively maintained through proper monitoring, inspection, and maintenance practices.

In summary, carbon steel is often used in boiler feed water lines due to its cost-effectiveness, strength, and suitability for high-pressure applications. However, the choice between carbon steel and stainless steel depends on various factors such as cost, corrosion resistance requirements, and operating conditions.

Hi,
Why we use Carbon steel in Boiler feed water lies? Why not SS?

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, ...
