Dear , You need to provide purging if thk. of SS pipe is less than 6 mm thk. Heat input during fillet welding of support to SS pipe thk.< 6 mm, produces heat tints on ID of pipe,which leads to service failures deoending upon corrosivity of carrying fluid. You can think. of reducing cost of purging by different means . Above 6 mm SS pipe thk. it is not required.API 582 has got guidence notes.Pl refer. Regards, Manish Kulkarni
