Dear All!!!
 
We are doing some Tanks as per API 650. In one of that tank ,we faced a problem like shortened the lingth of plate..and JOINT GAP became more than the required 'Root gap'. Almost   "55mm" we got .So we thought about 'Buttering'. But in API 650 not mentioned any thing about 'buttering'. So which standard we have to follow for it, and what are the test we have to conduct over there.
 
There was no PWHT as per WPS,Pre heat was only upto 40 ^0 C.
 
plate thickness is 23.4mm- 'Double 'v' groove' , ASTM 573.GR 70.
