[MW:34707] Re: Ice formation in SS 316

By Materials & Welding
Hi Manish,

For Stainless steel 316 (SS316), the Ice formation can lead to mechanical and structural issues, especially in applications where the material is exposed to low temperatures.

Damage Mechanisms:

  1. Brittle Fracture: At low temperatures, stainless steel, including SS316, can become more susceptible to brittle fracture. This is a type of failure where the material breaks without significant plastic deformation. Ice formation can exacerbate this condition.
  2. Stress Corrosion Cracking (SCC): The combination of low temperatures and the presence of certain corrosive agents can lead to stress corrosion cracking. Ice formation may contribute to the development and propagation of cracks in the material.

Mitigation Actions to Prevent Ice Formation:

  1. Insulation: Providing insulation to the stainless steel structure can help maintain higher temperatures and prevent the formation of ice. This is particularly important in applications where the material is exposed to low ambient temperatures.
  2. Heating Systems: Implementing heating systems, such as trace heating or electric heaters, can prevent the accumulation of ice on the surface of SS316. These systems can maintain the material at a temperature above the freezing point.
  3. Anti-Icing Coatings: Applying anti-icing coatings to the surface of SS316 can inhibit the formation of ice. These coatings are designed to reduce the adhesion of ice and promote easy removal.
  4. Thermal Blankets: Using thermal blankets or covers can help retain heat and prevent the cooling of SS316 in cold environments.
  5. Proper Design: Ensure that the design of the structure takes into account the environmental conditions it will be exposed to. This includes considering insulation, heating elements, and other preventive measures during the design phase.
  6. Regular Maintenance: Regularly inspecting and maintaining the equipment and structures made of SS316 is crucial. Identifying and addressing potential issues early can prevent the formation of ice-related damage.

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, ...
