Selection of pipeline series
Thread Content
The existing pipes are divided into Series A and Series B. Which series is being used more by everyone at the moment? Which one is more commonly used?
Series A is the internationally standard series (commonly known as imperial pipes), while Series B is the series still in use in China (commonly known as metric pipes)
Now, most domestic systems also use the A series, while the B series is being used less and less； It is recommended to use the A series entirely
It mainly needs to be compatible with your existing pipeline fittings~~~ Choose according to your needs~~~
In my opinion, in the fields of fine chemicals and pharmaceutical chemicals, Series B is more commonly used in China. For large-scale chemical processes as well as those that require high temperatures and pressures, Series A is more frequently utilized. As a design firm, it ultimately depends on the client’s preferences; I would recommend using the same series throughout the entire project, so as to avoid having some parts use Series A while others use Series B. . . I’ve experienced it once. . . It’s so embarrassing
The standards, whether for Series A or Series B, must be unified
I am most familiar with metric pipes of the B series.
Well, the modification or repair requires confirmation
