Plate tower manufacturing and inspection
Thread Content
We are about to build a plate tower, and I would like to discuss with everyone the requirements for manufacturing and inspection. The specific data are as follows. Gauge pressure of 0.18 MPaG, temperature of 90°C, material 304L, dimensions of 3.4×36 m, 52 trays. What gives me the most trouble is controlling the ellipticity and levelness.
Is the poster from a manufacturing factory? Workshop technician? For the manufacturing of tower equipment, you should pay close attention to the requirements set by your own factory; corporate standards should be higher than national standards, such as the allowable tolerances for manufacturing errors!
I am involved in third-party inspection; to be precise, I hope to discuss some experiences and key points regarding inspection and control. To control the levelness of the tray, which manufacturing steps should be paid attention to?
The roundness of the tower body must not exceed the limits specified by the container. The levelness of the tray is something that needs to be carefully controlled; generally, it is the upper surface of the tray support ring that is monitored for levelness. During welding, the upper surface of the tray support ring serves as a reference, and the marking positions must be accurate.
I’m not very familiar with tower design; I found some relevant information online. I hope it will be helpful to you! By the way, what material do you plan to use?

The requirement for ellipticity is limited to ±0.5% ID. With a diameter of 3.5 meters, the plate thickness is estimated to be at most 16 mm. So, supports must be installed during the processing process. How exactly do you play it? I would appreciate your advice. What are your suggestions regarding the determination of the tower’s centerline and the tray reference line, as indicated by the dashed lines?
Which standard specifies the roundness requirements for plate towers?
