Why are there only 3000 and 6000 grades for both socket branch pedestals and threaded branch pedestals?

Regarding branch pipe fittings: 1. Butt-welded branch pipe fittings are the most common type of connection for branches. Its end is beveled to be welded butt-to-butt with straight pipes, and thus it is considered a butt-welded fitting. The design of the butt-welded branch pipe support minimizes stress concentration and provides overall reinforcement. The butt-welded branch pipe fittings are available in three pressure grades: STD, XS, and Sch160. 2. The base of the socket-type branch pipe fitting is the same as that of the butt-welded branch pipe fitting, but its branch connections are made using socket welding. The socket branch pipe bases are available in two pressure grades: 3000# and 6000#. 3. The base of the threaded branch fitting is the same as that of the butt-welded branch fitting, but its connection to the main pipe is achieved through threading, eliminating the need for welding. The threaded branch pipe bases are available in two pressure grades: 3000# and 6000#. Why do socket branch fittings and threaded branch fittings only come in such high pressure ratings? Why does even a regular 10-kilogram pressure air pipe require such a high rating?
The socket branch fittings and threaded branch fittings are available in only 3000 and 6000 grades, as these two types of fittings are designed to withstand higher pressure and strength requirements. Such a design ensures the safety and reliability of pipe connections in high-pressure environments. Although for low-pressure systems such as 10-kilogram air pipelines, these high-grade branch connection stations may seem excessive, their use can provide additional safety by preventing connection failures caused by pressure changes or shocks. .
Both GB and MSS provide detailed specifications; the threaded type can handle 2000 pounds, while the socket-welded type can handle 9000 pounds. It seems to be related to the wall thickness of the connecting pipe.
So you mean its spelling should be incorrect.
At this stage, it is necessary to base things on the established international or **standards. Reputable design institutes also follow existing standards in their designs. Extract a segment of a chart.
I wonder which specification or standard this is taken from?
Thank you; this is a standard from a support and hanger association, and it actually relates to pipelines as well
