Re: [MW:35776] Re: low temperature pipe and ASTM A106

Dear 

 
ASTM A333 and ASTM A106 are both carbon steel pipe specifications, but they serve different purposes and have distinct characteristics.

ASTM A333 pipes are designed for low-temperature service, typically below -50°F (-45°C). They are made from low-temperature carbon steel and are suitable for applications where the pipes will be exposed to cold temperatures.

ASTM A106 pipes, on the other hand, are suitable for high-temperature service and are often used in power plants, refineries, and other high-temperature applications.

The main differences between A333 and A106 pipes are:

1.Temperature range: A333 pipes are designed for low temperatures, while A106 pipes are suitable for higher temperatures.
2. Material composition: A333 pipes have a specific chemical composition that ensures low-temperature toughness, while A106 pipes have a different composition that prioritizes high-temperature strength.
3. Mechanical properties: A333 pipes have specific requirements for impact testing and notch toughness, which are not required for A106 pipes.

Regarding SA 333 Gr.6 pipes below 2" in hot-finished condition, it's possible to supply them in this condition. However, it's essential to verify the specific requirements of your project or application to ensure compliance.

In terms of chemical composition and mechanical properties, low-temperature CS steel pipes like A333 typically have:

1)Lower carbon content to improve toughness
2)Specific requirements for manganese, silicon, and other elements to enhance low-temperature properties
3)Impact testing requirements to ensure toughness at low temperatures

A106 pipes, on the other hand, prioritize high-temperature strength and may have different chemical composition and mechanical property requirements.

Your experience with these pipes will depend on your specific application and industry.

Hi,
 
What is the real difference of ASTM A333 pipe from ASTM a106grB?
ASTM A333 is a low temperature CS pipe but 106 is not. What is the main features of Low temperature CS steel pipes by their chemical composition and mechanical properties?
Please share your experience on this.
 
Martin.

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, ...
