I urgently need advice from experts: Can a Q245 flange be welded to an L360 pipe with a weight of 100 kilograms?
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:
Push it, it’s very urgent, please help with the ball
It can be welded together. . . . But can it withstand 10 MPa? . . According to the design calculations, this thickness is insufficient
So, according to the design, if it’s 100 kilograms, what should the thickness of the welded surface be? If the flange is replaced with Q345 having a thickness of 13 plate thicknesses, can it be welded to the pipe?
Can it withstand pressure? Would it work if we replace Q245 with Q345?
It’s the thickness that’s not enough. . . Q345 is not enough either. .
The thickness issue is best considered in conjunction with temperature
The medium is water, at room temperature
With a diameter of DN500 and a pipe wall thickness of 11, it should not be able to withstand a pressure of 100 kilograms.
The pipe material is L360M, with dimensions of 529*11. Can such a pipe withstand a pressure of 100 kilograms? It was the customer who purchased this pipe
