Tube VS Pipe
PIPE — Standard Pipe TUBE — non-standard tube Tubes manufactured to ANSI and API standard specifications are called PIPE, and their dimensions are expressed as “nominal diameter.” All other tubes not manufactured to standard tube specifications are called TUBE or TUBING, and their dimensions are expressed in terms of outside diameter. Tube is a positive deviation tube with heat exchange.Pipe is a positive or negative deviation tube without heat exchange. Note: ANSI – American National Standards Institute (ANSI – American National Standards Institute) 1. the difference between sizes Tube and Pipe have standards; the standard series of tubes is more than Pipe. The pipe DN standard is not the outer diameter but is slightly smaller than the outer diameter and larger than the inner diameter. Can also do non-standard 2. the difference between the usage The tube is generally used in the container, especially the heat exchanger tube, and Pipe refers to more equipment outside the Pipe, so the general tube is translated as “pipe,” and Pipe is translated as “pipe.” The difference between Tube, Pipe, Tubing, and piping. The ASME Boiler and Pressure Vessel Code is very strict about the meaning of the terms tube, Pipe, Tubing, and piping, which are used in different applications. I have summarized my understanding of the four terms below for your discussion.1. The tube is round or has a continuous perimeter of any other cross-sectional shape of the hollow product. The dimensions of a round tube can be specified in terms of any two of the three diameters: outside diameter, inside diameter, and wall thickness.2, The Pipe by ASNI B36.10 and B36.19 (for stainless steel) is listed in the nominal size of the round cross-section of the tube, and its diameter is expressed in NPS No. NPS No. The actual outside diameter is…
