Stress elimination of seamless steel pipeline engineering refers to reducing the stress of pipelines during construction and use through some methods to maintain the safety, stability and performance of pipelines. Common stress elimination methods for seamless steel pipelines include the following:
1. Adjust the support method of pipelines
By changing the support method and layout of pipelines, optimizing the planning of pipeline support structures, avoiding long-term single-direction forces on pipelines, appropriately increasing the support points of pipelines, adjusting the support stiffness of pipelines, etc., the purpose of stress elimination can be achieved.
2. Install expansion joints
The expansion joint is a special element in the pipeline system that can absorb the thermal stress caused by the expansion and contraction of the pipeline and buffer the impact stress caused by earthquakes or other reasons, thereby eliminating the stress of the pipeline.
3. Install vibration dampers
The vibration damper is a device that can absorb the vibration and impact of the pipeline system, which can convert the vibration and impact of the pipeline system into other forms of energy, thereby reducing the stress of the pipeline system and protecting the safe operation of the pipeline.
4. Adjust the construction method of the pipeline
Reasonably arrange the construction procedures and construction sequence of the pipeline to avoid excessive stress impact on the pipeline during the construction process, and effectively reduce the stress of the pipeline.
5. Detect the pipeline condition
Perform vibration test, stress test and stress analysis of the pipeline in time, find the stress problem of the pipeline in time, and perform necessary maintenance and adjustment on the pipeline to eliminate the stress of the pipeline.
In short, there are many methods for eliminating stress of seamless pipelines, and it is necessary to choose the appropriate method according to the specific characteristics and management requirements of the pipeline system. At the same time, in the process of designing, installing, using and maintaining the pipeline system, attention should be paid to the prevention and treatment of pipeline stress problems.
