Precautions for the manufacturing and installation of chemical storage tank manufacturers

Chemical storage tank manufacturer manufacturingInstallation construction precautions

1. The approval of pre-construction materials such as construction plans should be combined with the actual site construction.

2. Verify the materials for the bottom plate, wall plate, and top plate in that order to ensure no materials are missing.

3. After starting anti-corrosion, calculate the total required amount based on actual usage to prevent shortages later.

4. The labor protection for the tank top is structural steel, and the design specifies the tonnage. Currently, materials are all positively deviated, which may lead to insufficient length during construction. Calculate and coordinate in advance.

5. There are many accessories for the storage tank. When the project team lacks experience, to ensure no accessories are overlooked, the construction team can be asked to report their plans, which the project team will then review. Significant discrepancies must be taken seriously. To ensure progress, try to keep accessories as semi-finished products and avoid ordering loose parts.

6. Areas requiring heat treatment should be considered in advance to avoid affecting the overall construction period due to one item.

7. The cutting of the tank bottom plate and wall plate is fundamental, especially the geometric dimensions. It is necessary to ensure that the edge lengths meet the requirements and that the diagonals are also correct; otherwise, it will be difficult to ensure that the tank body meets the geometric requirements.

8. When bending the wall plate, an arc guide plate should be made, or other methods should be used to ensure there are no straight edge sections. The curvature must be strictly checked against the arc plate; otherwise, it will be difficult to handle during installation. A good foundation for later installation must be laid by conducting random inspections.

9. The top plate and wall plate that have been properly bent must be placed on a fixed mold; otherwise, they are likely to deform.

10. The welding of the tank bottom plate is crucial, especially since the skill levels of construction teams may vary. High standards and strict requirements should be set at the beginning.

11. The welding of the tank bottom plate must strictly follow the sequence of welding the edge plates first, then the middle plates. The gap and welding amount of the edge plate seams have special requirements, generally requiring X-ray non-destructive testing.

12. The middle plates must adhere to the sequence of first electric welding, then short welds, and finally long welds. Long welds should be segmented and retreated. The welding process must strictly follow the welding procedure to minimize deformation; otherwise, it may not pass inspection by the owner and supervisor.

13. The seams between the edge plates and middle plates should be left until the end to avoid making fundamental mistakes.

14. Vacuum boxes and other equipment should be prepared in advance, and the negative pressure gauge should be calibrated ahead of time to avoid delays when needed.

15. The orientation of laying the tank bottom plate is very important. The position of the holes on the tank body relates to their location and must also consider the distance to the welds.

16. The current power used for tank body welding is relatively high, and sometimes it may be necessary to work overtime or add personnel to meet deadlines. The cables must be carefully considered; do not wait until the middle of the process to add or replace cables.

17. During the rainy season, it is essential to consider site drainage and rain protection, especially since the schedule for section four is already behind. Do not let drainage and rain protection further affect the schedule.

18. The welding and geometric dimension control of the storage tank are challenging. Welding must ensure that the welders are qualified, and good communication must be maintained to guarantee the pass rate. Geometric dimensions require meticulous work; a solid foundation must be laid to ensure quality. Start with higher standards to facilitate approval from supervisors and owners, and avoid becoming a negative example.

19. For inverted construction methods, the maximum lifting weight must be calculated, considering the safety factor, and determine the size, quantity, and chain hoists of the lifting columns to ensure safe lifting.
