It is well known that pipeline equipment can absorb equipment vibration and reduce the influence of equipment vibration on pipeline. Rotary compensator can greatly reduce vibration and noise of pipeline system, and can fundamentally solve the problems of interface displacement, transverse expansion and non-centrality of various pipelines. In the field of corrugated expansion joints in our country, we should make use of technological innovation to make the brand of single-type universal-angle hinge corrugated expansion joints famous, so that the enterprises of single-type universal-angle hinge corrugated expansion joints in our country can truly surpass the international advanced level, so as to replace the key technical equipment of corrugated expansion joints. The import-dependent pattern is used for the key equipment of corrugated expansion joints. The localization of technological innovation makes the single-type universal-angle hinge corrugated expansion joints. Enterprises can stand in the market for a long time.

With the growing weakness of the corrugated expansion joint market at home and abroad, the market competition of low-end products is becoming more and more fierce, which causes some enterprises to run into difficulties. In order to seek survival, unfair competition means are adopted, resulting in chaos and disorder in the industry market. Facing the cruel competition, the single-type universal-angle hinge corrugated expansion joint enterprises need to start with technological innovation, quality innovation, management innovation, service innovation and other aspects to win the market with a better attitude.

In order to improve the competitiveness of single-type universal-angle-hinge corrugated expansion joint enterprises in the market, we must start with innovative sales model. In order to achieve a long-term goal, we must firmly establish our core competitiveness and vigorously explore new development paths. E-commerce marketing model is also a point of economic growth worth exploring, which requires single-type universal-angle-hinge corrugated expansion joint enterprises to adhere to technology. Innovation.

It is understood that in the next three to five years, the localization of pipeline equipment will be the main theme of industry development, but at present, the industry of single universal angle hinge bellows expansion joints is at the forefront of localization. Nowadays, the idea of localization of single universal angle hinge corrugated expansion joint is very clear. The working idea of localization of single universal angle hinge corrugated expansion joint pipeline equipment is to adopt "1+N mode of government, industry, education and research". The practice of nationalization in recent years shows that this mode is not only an important organizational guarantee to ensure the smooth progress and effective results of the nationalization of pipeline equipment, but also an organizational mode that should be adhered to in promoting the nationalization process in an all-round and in-depth manner.
