Solving for flanges: What does CL.B mean? My understanding is that CL refers to American standard flanges, and B refers to stainless steel, is that correct?
Letters are best understood within a sentence. . . . . . . . . . Too little was given; you want everyone to guess. . . . . . . . . . CL refers to the pound rating; it can also denote the grade of the flange material. B definitely does not mean stainless steel – how can the original poster mix up Chinese and English concepts like that? SS stands for stainless steel, while B may refer to the diameter series of pipes. The original poster, guess more
CL: It is the pressure rating, usually expressed as CL2500. B might refer to the model of the pipe, I guess
CL refers to the pound class, and it also denotes the grade of the flange material
It would be better if you wrote down all the markings so I can help analyze them. In 20592, it is indicated as: wn150(B)-16RF, 20#. The Ministry of Chemical Industry labels it as follows: wn150(B)-1.6RF,20#
The other party wrote the flange material as: CL.B
Emotional CL refers to the material. . . . . The initial letter of the pinyin; B may refer to carbon steel. In the past, when indicating pipe grades, L1B was used, and B stood for carbon steel. Determine the material of your pipe to infer the material of the flange
The 7th floor is kind of interesting, right? ?
The customer only gave this much, so I can only guess
It is also possible that CL denotes the pound rating, while large-diameter flanges (24\" and above) will have Series A and B
