ASTM A106 Grade C SCH 80 Black Seamless Carbon Steel Pipes

Description

ASTM A106 Grade C SCH 80 Black Seamless Carbon Steel Pipes

ASTM A106 seamless pipes (also known as ASME SA106 pipes) are commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers and ships. These pipes must carry fluids that exhibit higher temperature and pressure levels And gas.ASTM A106 pipe includes three grades, A106 grade a, A106 grade b, and A106 grade c.
About ASTM A106 Gr C
ASTM A106 Gr C seamless pipes (also known as ASME SA106 GR C pipes) is a carbon-manganese steel pipe for high-temperature large-diameter boilers and superheaters. Its chemical composition is simple and similar to 20G carbon steel, but its carbon and manganese content is higher, so its yield strength is about 12% higher than that of 20G, and its plasticity and toughness are not bad. The steel has a simple production process and good cold and hot workability. Using it to replace 20G headers (economizer, water wall, low-temperature superheater and reheater header) can reduce the wall thickness by about 10%, which can save material costs, reduce welding workload, and improve headers The stress difference at start-up.

Tips: ASTM standards are divided into the following six types.
1. Standard Test Method: It is a prescribed procedure used to identify, test and uate the quality, characteristics and parameters of materials, products, systems or services.
2. Standard Specification: It puts forward technical requirements and specific instructions for materials, products, systems, or projects, and also proposes procedures that should be adopted to meet the technical requirements.
3. Standard Practice: It is a program that explains one or more specific operations or functions, but does not produce test results.
4. Standard Terminology: It describes or defines nouns, and explains symbols, abbreviations, and acronyms.
5. Standard Guide: It selects a series or explains its usage, but does not introduce specific implementation methods.

6. Class Fication: It distinguishes and classifies materials, products, systems, or specific services according to their source, composition, performance or use.

FAQ:
Q: What is the difference between pipe design material A106 and SA106?
A: There is no difference between pipe design material A106 and SA106,
Because the 2013 edition of the ASME II material chapter has pointed out that SA106 is consistent with ASTM A106,In addition, SA106 is a grade of American ASME,And A106 is the grade of ASTM.
Q: What does the mark CD in the steel pipe SA106Gr.B standard mean?
A: CD means cold drawn,SA106 stipulates that pipes below DN40 can be hot-rolled or cold-drawn; pipes above DN50 are conventionally hot-rolled. When the manufacturer and the purchaser reach an agreement, cold-drawn manufacturing is allowed.
Q: What is the difference between ASME SA-106 and ASME SA-106M?
A: The difference between ASME SA-106 and ASME SA-106M is that if the size standard is imperial, use ASME SA-106, if the size standard is metric, use ASME SA-106M.
ASTM A106 Grade C SCH80 Black Seamless Carbon Steel Pipes and ASME SA106 seamless pressure pipe is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.
