Pipeline transportation is one of the most important material transportation modes, and has the main characteristics of large transportation volume, small occupied area, short construction period, low cost, safety, reliability, strong continuity, low energy consumption, high benefit and the like, so that the pipeline transportation is widely adopted by countries in the world. According to 2010 statistics, the total length of transportation pipelines (including natural gas, crude oil and chemical products) in the world is about 200 kilometres, with china having about 7.6 kilometres and growing in the range of 5-10% per year on average. Therefore, long-distance pipeline transportation is just an irreplaceable transportation form, becomes an important ring in social development and plays a crucial role in global economic development. Besides the great potential safety hazard of welding in open flame, the welding seam has internal defects and external defects. The corrosion problem of oil and gas pipeline facilities is very serious, and particularly in the high-temperature and high-pressure pipeline work, once damage occurs, not only direct economic loss of leakage of petroleum equipment and pipelines and crude oil leakage accidents can be caused, but also serious accidents such as fire disasters and explosions can be caused, and environmental pollution and other serious consequences can be caused.
Threaded connections are one of the common connections used by modern structures and machinery. Generally, threaded connection has self-locking performance, but can be loosened under the action of variable load, impact and vibration and when the working temperature changes greatly, so that the pretightening force is reduced. The use practice, the relaxation performance test and the fatigue strength test of the threaded connection prove that: loose failure is one of the primary failure modes of threaded connections that are subject to alternating loads. The loosening of the threaded connection causes the connection pretightening force to be smaller or even lost, thereby reducing the quality of the threaded connection, causing the early damage of each part in the connection and even causing the connection to be loosened. In practical application, equipment and personal accidents caused by loose and falling connection are frequent.
