Although it is said that waste should be recycled now, in many cases, it also gives criminals an opportunity to cheat us by using inferior products or replacing the old ones with new ones. For equipment like glass lined reaction tanks, the effect of the old and the new ones is naturally different. So how can we ensure that what we choose is new?
1. It can be seen that the outer weld of glass lined reaction tank can have repair traces if the weld is renovated.
2. Check the marks around the drain hole under the tank body. If the new tank is forged and welded, the spray paint surface will be smooth, and there may be some forging marks. The renovation situation is different. Although some are smooth, there will be rust marks on the upper flange. Even if the rust is removed, the pit will leave traces.
3. The new tank at the steam inlet of the interlayer of the tank body usually has a steam separation device to prevent porcelain from falling off due to excessive steam impact. The renovated tank may not exist because of excessive use of gas. Finally, it is uncertain that an identification unit can be found to measure the wall thickness with a detector. That's all.
4. See if the welding pass of jacket and cylinder is flat and even, and then look at the finish of paint.
5. It can also be used to measure the thinning of steel plate and the deformation of tank body.
There are always methods. We have to learn to use different methods to detect, and the situations that need our preparation and attention are also different at different times. Therefore, we can better select the glass lined reaction tank we want.
