I’ve been confused about threads; I need help
Thread Content
For example, instrument wiring ducts (6-inch pipes, also known as DN20 pipes?) Is it also called a 3/4-inch pipe? Are all three statements correct? ), To connect flexible pipes, threading is generally required; so what is the name of the threads that are created through this process? G3/4''？ DN20？ What should it be called?
G3/4 3/4 is a size code that indicates the diameter of the pipe, while G is a code specifying the thread type; NPT is another common type of thread
There are countless types of pipe threads both domestically and internationally, and it has taken many years to understand them all. Rc Rp G ZG NPT NPSM, and many more. New, old, domestic, foreign.
3/4 = DN20 = 6 inches; this refers to the pipe diameter, while G, PT, NPT, etc. indicate the thread specification
3/4 = DN20 = 6 inches; this refers to the pipe diameter, while G, PT, NPT, etc. indicate the thread specification
The pipeline size corresponds to the one shown in the figure below； The threads are another set.
