The DBW large corrugated box compensator is one of the important components for pipeline installation. The large corrugated box compensator has the advantages of small volume, easy installation, small footprint, reduced labor intensity, labor-saving, labor-saving, material saving, and strong practicality. The expansion and contraction capacity of the large corrugated box compensator is between 60-120mm, without leakage or filling, with good expansion and contraction performance, safety and reliability. The large corrugated box compensator can also save maintenance workload. At the same time, the large corrugated box compensator can be installed without an expansion well, reducing engineering costs. The compensator has a novel and reasonable structure, no vulnerable parts, small volume, light weight, and is easy to install and transport. The large corrugated box compensator is an ideal product for pipeline installation.  
Design and construction instructions for large corrugated board box type compensator:
1. The pressure of the large corrugated box type compensator is below 1.6MPa, and the medium used is hot water, steam, gas, various oils, with the same temperature as the pipeline. It is best used in high-rise buildings;  
2. The maximum thrust of the large corrugated box compensator is 0.8-1.2T, and the fatigue life is 6500 times;  
3. The large corrugated box compensator can be widely used in overhead pipelines, trench pipelines, and buried pipelines;  
4. Compensator steering bracket can be installed or not;  
5. The large corrugated plate box type compensator is only suitable for axial installation (straight pipeline);  
6. When using large corrugated board box type compensators for trench pipelines, there is no need to build compensator wells;  
7. It is strictly prohibited to ignite the expansion box of the large corrugated plate compensator during installation;  
8. The large corrugated board box type compensator has two waves of pre tension of 25mm-30mm and four waves of pre tension of 50mm-60mm;  
9. Practice has proven that in high-temperature water and heat pipe networks, a two wave expansion joint should be installed above 60m, a four wave expansion joint should be installed above 120m, and a two wave expansion joint should be installed within 30m of steam pipes according to design standards.
