English term or phrase: header wall thickness is schedule 10S
All austenitic, duplex and super duplex stainless steel reinforced branch fittings where the required header wall thickness is schedule 10S shall be ‘Lightweight Design’ manufacturer’s standard designed in accordance with ASME B31.3, qualified to MSS SP-97.The maximum design pressure shall be limited to the maximum flange pressure rating for the specified material. SUPPLIER shall provide details of burst test certification with their bid.

سمك جدار أنابيب التوصيل الرئيسية (على شكل حرف تي) يصل إلى 10 بوصة
Explanation:
سمك جدار أنابيب التوصيل الرئيسية (على شكل حرف تي) يصل قطرها إلى 10 بوصة

I would like to describe my questions more detail. In the piping material specification, the pipe wall thickness for 4" is Schedule 40S, for 10" pipe, the wall thickness is 10S, and there shown in the branch table that reducing tee applied for 10"x4", so a thicher wall branch and thinner header tee required.

When performing piping stress analysis, that reducing tee were also modeled. The SIF according to ASME B31.3 for tee is so not reasonable, Hope it wiill be revised in next version. Sometimes, without FEA tools on calculate the real SIF for tee, we just make a thicker wall thickness tee instead incase if piping stress exceed on the tee.
For the example 10"x4" Sch10SxSch40S reducing tee, we manualy changed the header of the tee from 10S to 40S and make a 10"x4" Sch40SxSch40S tee in CAESAR II to pass the stress analysis.

For such case, according to LittleInch, do we should better to use weldolet instead of reducing tee with a thicker branch and thinner header?
Another assumption is that the reducing tee manufactory could offer the 10"x4" Sch40SxSch40S reducing tee and leaving the 10S BW end on header for welding to pipe. If this assumption is correct, we will pay much attention on piping stress analysis in CAESAR II to model the correct wall thickness for tees.
