Aaahhh ..... and we take another tiny step forward in this third world guessing game !!!
Now, Najeeb, can you try to state your entire question, in english, so that we may have some hope of answering it ?
Most of the engineering seniors have dropped out of eng-tips because they grow sick and tired of trying to tease details out of hostile newbies who either cannot use the language, or feels.... somhow .... a compete explanation is "kowtowing" to the man.
I am on the edge ....
Now, restate your entire question with all appicable details necesary to formulate an accurate and complete answer ..... You can do it !!!

Where:
R1 = bend radius at center of pipe
D = OD of pipe
nt = nominal pipe thickness - undertolerance - corrosion - mechanical allowances.
Thinning Due To Bending:
Ro [in] = R1+(D/2) ~ outside radius
Pt [%] = (Ro-R1)/Ro ~ thin out
tmin = nt*(1-Pt) ~ minimum outside radius thickness
Required Thickness: 304.2
Intra [in] = ((4*(R1/D))-1)/((4*(R1/D))-2) ~ intrados (inside bend radius) 304.2.1(3d)
Extra [in] = (4*(R1/D)+1)/(4*(R1/D)+2) ~ extrados (outside bend radius) 304.2.1(3e)
tinside [in] = (P*D)/(2*((S*E*W)/Intra) + P*Y) ~ 304.2.1(3c)
Checktinside = nt>=tinside
toutside [in] = (P*D)/(2*((S*E*W)/Extra) + P*Y) ~ 304.2.1(3c)
Checktmin = tmin>=toutside
tcenter [in] = (P*D)/(2*((S*E*W)/1) + P*Y) ~ 304.2.1(3c)
Checkt = t>=tcenter
