【A simple question about heat exchangers】
Thread Content
For a floating-head heat exchanger, with a shell made of Q345R material and a diameter of 600 mm and a thickness of 10 mm, should it be manufactured by 【rolling】 or 【welding】? （）
The cylinder is formed by 【rolling】 followed by 【welding】, or a DN600 pipe can be used directly.
It involves welding after rolling; sheets can be used, as well as tubes.
