How to inspect the purchased tower and reactor.

First, conduct a visual inspection to check whether the anti-corrosion paint has been applied evenly, whether the overall shape is intact without any abnormal deformations (I’ve encountered a situation where a container was overturned during transportation and fell into a pit; the transporter tried to hide this by using putty, but it was discovered during inspection and the container had to be sent back to the factory for repair), and whether the welds are proper and free from any undercutting； Next, measure the external dimensions: the length and diameter of the container, the thickness of its walls, as well as the size of any openings. If possible, weigh the container as well. For containers made of special materials, a spectral analysis should be conducted to verify the composition of the metal materials used in their construction ； Third, check against the drawings to ensure the orientation of the pipe ends is correct ； Fourth, check whether all accessories for the container are present: whether the lifting lugs and grounding plates have been welded in place, whether the flanges at the pipe ends are available, the quantity of fasteners and gaskets, the spare parts required for installation and trial operation (gaskets), the spare parts needed for a two-year period (bolts and nuts), the quantity of foundation bolt nuts, the number of special tools required for installation and pressure testing, as well as the quantity of connectors and attachments inside the tower. Also, verify whether the foundation formwork for large containers is transported together with the equipment ； Fifth, whether the quality certification documents of the container, such as its nameplate, certificate of conformity, and as-built drawings, meet **relevant standards and are complete. That’s basically it. During the inspection, the manufacturer, the installation unit, and your client all need to be present; after the three parties sign off on the inspection, the large components are handed over to the installation unit, while the spare parts are taken back to your own warehouse. Then you can go back to the office to drink tea and rest.

Quantity, specifications, model. It’s best to take the installer along for the inspection.

What was said upstairs is quite comprehensive; it was mentioned that weight checks during acceptance may not always provide accurate information. For example, when a hydraulic test is conducted before leaving the factory and the water is not completely drained, the weight measured can often be much higher than the weight specified in the drawings.
