Pressure pipelines – Standards for pipe materials
Thread Content
Please tell us the pipe material standards used for pressure pipelines GC1(1), GC1(2), GC1(3), GC2, and GC3 respectively； By the way, which pipe material standard is generally used for non-pressure pipes? Are there any standards or books that specifically cover this topic? Could you give some advice? Thank you!
These are specified in GB/T 20801; you can find the relevant standards by doing a search
Your question is too broad; there isn’t a very clear corresponding relationship between the pressure pipeline grades and their materials
In my opinion, the choice of pipeline material should primarily take into account the properties of the medium being transported (especially flammability, explosiveness, corrosivity, etc.), as well as operating temperature and pressure. I recommend a book to LZ: Pressure Pipeline Materials (A Professional Training Textbook on Pipeline Materials). Table of Contents: Part One – Selection of Materials for Pressure Pipelines. Section 1: Basic Properties of Common Metal Materials Used in Pressure Pipelines. Section 2: Terms Related to Metallography. Section 3: Methods of Designating Steel Grades. Section 4: The Role of Impurity Elements and Alloying Elements in Steel. Section 5: Differences Between Cast Iron and Carbon Steel in Terms of Chemical Composition, Metallographic Structure, and Properties. Section 6: Quality Grading of Steel. Section 7: Common Corrosive Environments in Petrochemical Production Processes. Section 8: Heat Treatment of Metal Materials. Section 9: The Impact of Temperature on Material Selection. Section 10: Application Limitations of Common Metal Materials Used in Pressure Pipelines. Part Two – Selection of Equipment for Pressure Pipelines. Section 1: Standards for Common Equipment Used in Pressure Pipelines. Section 2: General Requirements. Section 3: Requirements for Selecting Steel Pipes......
