ASTM STANDARDS FOR PIPES HOW TO
ASTM STANDARDS FOR PIPES SERIES

There are different standards to describe the steel pipe size, OD and wall thickness. Therefore, thatвЂ™s why we always need to know a right pipe size.

Through these characters we could calculate the pipe weight, how much pressure pipe could bear, and the cost per foot or per meter. Steel Pipe Dimension 3 charactersДЄ completely description for steel pipe dimension includes outer diameter (OD), wall thickness (WT), pipe length (Normally 20 ft 6 meter, or 40 ft 12 meters).

ASTM STANDARDS FOR PIPES HOW TO

Means of Nominal Pipe Size (NPS) and Nominal Diameter (DN)ДЄnd finally, we will tells you how to describe steel pipe dimensions & sizes correctly.

Pipe Size Schedule (Schedule 40 & 80 steel pipe means)

So, what are the exactly right ways to express the steel pipe dimensions?ДЇor your better understanding, we will explain from below aspects:Дimension Standards of carbon and stainless steel pipe (ASME B36.10M & B36.19M) In case any misunderstandings or a different size we purchased, that will be a big trouble. Class Fication: It distinguishes and classifies materials, products, systems, or specific services according to their source, composition, performance or use.People always confused about how to describe steel pipe dimensions (sizes) in correct ways, or how to clarify to seller what exactly pipe size we are going to purchase.

ASTM STANDARDS FOR PIPES SERIES

Standard Guide: It selects a series or explains its usage, but does not introduce specific implementation methods.Д¦. Standard Terminology: It describes or defines nouns, and explains symbols, abbreviations, and acronyms.ДҐ. Standard Practice: It is a program that explains one or more specific operations or functions, but does not produce test results.Д¤. 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.ДЈ. 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.Дў. Tips: ASTM standards are divided into the following six types.ДЎ. Q: What is the difference between ASME SA-106 and ASME SA-106M?ДЄ: 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. When the manufacturer and the purchaser reach an agreement, cold-drawn manufacturing is allowed. Q: What does the mark CD in the steel pipe SA106Gr.B standard mean?ДЄ: CD means cold drawn,SA106 stipulates that pipes below DN40 can be hot-rolled or cold-drawn pipes above DN50 are conventionally hot-rolled. Q: What is the difference between pipe design material A106 and SA106?ДЄ: There is no difference between pipe design material A106 and SA106,Д«ecause 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. Tensile requirement of ASTM A106 grade a, bВ and c. Note: Total of Cr, Cu, Mo, Ni, and V shall not exceed 1% 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.Д¬hemical Requirements of ASTM A106 grade a, bВ and c Grade The steel has a simple production process and good cold and hot workability. 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. Mechanical properties: Гіbв‰Ґ415 пјЏ MPa, Гіsв‰Ґ240 пјЏ MPa.ДЄSTM A106 GrВ C seamless pipesВ (also known as ASME SA106В GR CВ pipes) is a carbon-manganese steel pipe for high-temperature large-diameter boilers and superheaters. 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.ДЄSTM A106 GrВ B seamless pipesВ (also known as ASME SA106В GR BВ pipes)В is a cs seamless pipe nominal pipe for high temperature use.The chemical composition of A 106Gr.B is as follows:ДЎ. 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.
