Re: [MW:29766] A335 P11 can be used instead of P22

Hi, 

If header pipe is P5A why it is connected with P4 CAP (Tie-in point)? in which P5A weldolet to be fused with P4 CAP? is that your query? 

Is this pre approved design or shortage of material? so you just inserting one what you have?

write a TQ to ''the company'' take approval with disimilar WPS.

I hope there shall not be an issue if you are proposing with your adjustment in case, but designers approval is final.

Yours
