RPad

Hi All,

I would like to know if there is a rule of thumb when there is a need to start using reinforcing pad for certain sizes of reducing tee (weld type).

Thank you.

Regards,

Too many inputs to do that (Design pressure, wall thickness, temperature, size ratio, material strength, corrosion allowance) etc.

If you don't want to do the relatively simple calculation to your design code just buy a weldolet. Or a reducing tee fitting. They've done it for you.

When you cannot make up your assembly by using standard reducing RedTee. ie there are no 24 x 2 standard RedTee.

He's asking for when do you simply stab in a pipe and weld it up and when do you need to add a re-pad to that...

In that case, whenever you don't want to risk a broken pipe at that kind of a stress concentrator.
