What is a round metal compensator?
The nominal diameter of the circular metal bellows compensator should be larger than the steel specification by 4 mm, the angular diamond should be larger than 45 mm, and the top of the circular metal bellows compensator should extend to about 2 circular metal bellows compensator mm. The current should be strictly controlled throughout the welding process to avoid burning the circular metal bellows compensator. If the round corrugated metal compensator is located on top of the precast concrete wall, it depends on the specification and function of the round corrugated metal compensator. Smaller in size, the circular metal corrugated compensator can be easily connected to the main reinforcement, but it needs to be positioned throughout the concrete pouring process. Pre-embedded parts should be checked anywhere and anytime for immediate problem solving. Once completed, secure with anchor cables. In addition, an angle iron of appropriate size is placed on top to avoid the offset of the circular metal bellows compensator and pop up on the circular metal bellows compensator if necessary. In order to ensure the surface cleanliness of the bellows during processing and reduce damage, the surface film of the bellows is protected until it needs to be removed.
The strength of the circular metal corrugated compensator buried in the pipeline endangers its service life, but is clearly insufficient due to fracture. In addition to the opening strength, the fatigue strength of the circular metal corrugated compensator buried in the pipeline is also harmful, and cracks will definitely appear when the specified fatigue strength is exceeded. Before the construction of the pre-buried parts, the type, fitting and total number of pre-buried parts should be mastered, and the ground bolts should be fixed according to the specification.
 
The raw material of round metal corrugated compensator should be ensured as qualified products. Therefore, we should inspect it before production and processing, and immediately conduct physical property tests and element tests. If there are no obvious defects on the surface, the round corrugated metal compensator should be straightened and laser cut according to the corresponding specifications, and the thick round corrugated metal compensator marked and laser cut for laser cutting. For some structural pre-installations and special requirements, attention should be paid to the size and perspective of the anchor hooks.
