I would like to ask whether Q245 flanges can be welded to L360M pipes?
Thread Content
As the title indicates, there is a construction site where there is a batch of flanges made of Q245 material, with a pressure rating of 100 kilograms. The flanges have a diameter of DN500; they are necked butt-welded flanges, with 13 weld layers. There is another set of pipes made of L360 material, with a pressure of 100 kilograms, a diameter of DN500, and a wall thickness of 11 units. May I ask, can these two materials be welded together at a pressure of 100 kilograms and with this welding thickness, and can they be used normally? It’s extremely urgent; I’m waiting online. I hope the experts here at HaiChuan can help me – I’d be extremely grateful! ! ! :hug:. .
Please help answer, I’d be extremely grateful!
Under high pressure, it is not recommended to weld in this way
