One Question per Day in Applied Chemistry 8-21
Thread Content
Leveraging knowledge related to applied chemistry, including (analytical chemistry, physical chemistry, principles of chemical engineering, CAD drawing), we are launching the \"One Question per Day\" activity; simply reply to get the answer. To encourage continued participation from everyone! Get 3 wealth rewards for replying! 5 correct answers = wealth! I hope everyone will participate actively, learn together, and make progress together! ! ! What is the nominal wall thickness for DN80 SCH20? 4.5
SCH20 represents a wall thickness grade; for the same nominal diameter, different grades have varying wall thicknesses. In ANSI/ASME B36.10M (19M), there is no distinction for SCH20 grade for pipes smaller than 8 inches; specifications for wall thickness apply only to pipes of 8 inches or larger. For example, the wall thickness of an 8-inch SCH20 pipe is 0.250 inches. In GB12459, specifications for SCH20 wall thickness apply only to pipes with a DN of 50 or greater. Example: The wall thickness of SCH20 with DN50 is 3.2 millimeters
There are no pipes of this size and grade available!
There is no Sch20 in the standards; if interpolation is used, the value should be between 3.58 and 3.96. Refer to standard ASME B36.10
