Pipe material
Thread Content
What are the European standard materials corresponding to A11 and MA1 in the American standard for pipe materials?
Is no one clear? It’s urgent, please help.
There is too little information; please list the detailed specifications for the pipe material. . . :lol
Could you explain it more clearly to the original poster?
I am referring to the pipeline numbering in flowcharts; for example, SMLS-A1-SCH-∮ outer diameter×wall thickness. A1 denotes steel grade 20, A3 denotes Q235-A, and A6 denotes steel grade 35 – these are according to national standards. I don’t know what materials A11 and MA1 represent in the American standards
There are no terms like A11 or MA1 in American standards; these are usually defined by design firms or engineering companies themselves. Look for the relevant instructions – there is usually a diagram or a grade table that provides explanations
The designer specified 5MA1-HC, saying it is a US standard; I’m not sure about that either.
There should be a legend on the image on the home page; the number following A is the serial number of the material. For example, A1 refers to 20# steel, while A2 refers to Q235... If there is no legend on the design drawings, ask the designer for it – only he knows the meaning of these symbols.
