Fitting (weldolet) Material for A106 Gr. C Pipe
Fitting (weldolet) Material for A106 Gr. C Pipe
(OP)
I'm trying to make a branch connection with the following specifications:
Header - 16 in., Sch. 160, A106 Gr. C
Branch - 4 in., Sch. 160, A106 Gr. C
Design Press. 3210 psig
Design Temp. 490 F
Needs to meet ASME B31.1 Branch Reinforcement Requirements
I'm wondering if anyone knows what type of fitting material (for a 4" weldolet) would have the same properties as A106 Gr. C pipe? I've been told to use A105 material but the mechanical properties aren't quite the same. Can a weldolet be made of A234 Gr. WPC? This material has the same mechanical properties as A106 Gr. C pipe and it is used for butt weld elbows in the same service. However, I've never heard of weldolets being made of A234 Gr. WPC.
Material Properties from ASME B31.1
A106 Gr. C Minimum Tensile = 70000 psi; Minimum Yield = 40000 psi; allowable stress @ 500 F = 20000 psi
A105 Minimum Tensile = 70000 psi; Minimum Yield = 36000 psi; allowable stress @ 500 F = 19600 psi
A234 Gr. WPC Minimum Tensile = 70000 psi; Minimum Yield = 40000; allowable stress @ 500 F = 20000 psi
Please advise.

just weldolets have build-in reinforcing properties and what you need is to read the Code for your calculations, if you have a comp program will be better (if you can also figure out how to use too),
You need a lot of reading and consulting.
