Regarding the thickness of the GD87 tee

This post was last edited by Frozen Chick on 2020-7-15 at 16:49. The tee material from GD87 comes in three different thicknesses: a, c, and s. There is a significant difference in thickness between a and c. What is the difference between these three thicknesses? If a GB12459 tee is used, which thickness of a or c is the specified wall thickness? https://p3.ssl.qhimgs0.com/sdm/500_500_60/t01b573f81b43a3f382.jpg
The branch pipe is pushed out from the main pipe, so its thickness becomes thinner； Under normal use, the thickness at the connection points of the main pipes and branch pipes should be the same.
S is the wall thickness of the tee; thinning of the wall thickness occurs during the extrusion process of the tee, so a thicker wall thickness is required. C represents the required wall thickness for the main pipe of the tee, and it is the same as that of pipes of the same grade. A denotes the required wall thickness for the branch pipes of the tee, which is also the same as that of pipes of the same grade
The thickness at the connection points of the main pipes and branch pipes should be the same. -------------------------------------- It is the same only in equal-diameter tees; for tees with different diameters, these two values are different. For American standards, the corresponding pipe specifications must be used, while for Chinese standards, specific numerical values must be provided
