Material of circulating water pipes and elbows
Thread Content
The circulating water pipeline has a diameter of DN500 and a pressure of less than 1.0 MPa; I would like to submit a plan for procurement. How should I specify the material and wall thickness of the pipeline, as well as those details related to elbows? What information is needed, and how should elbows be selected? If anyone knows, please let me know. Thank you
Bore size, pressure, material; elbows are generally 90 degrees.
The pressure-bearing capacity of a pipe is determined by its diameter, wall thickness, material, and operating temperature, with the actual industrial conditions playing a role in this determination. The pressure-bearing capacity of elbows can be determined using the same criteria as those for pipes, with distinctions made between short-radius and long-radius elbows
Refer to the relevant information in the chemical process design manual; for elbows, a diameter of 1.5D is generally chosen
I did the calculations for you: a wall thickness of SCH10, 6.35 mm, is sufficient; the material to be used is 20#, and the corrosion margin chosen is 3 mm
