Pipelines are the "lifeline" equipment for the production and development of offshore oil and gas resources and mineral resources. Traditional rigid pipeline technology has matured, but limitations in bendability, corrosion protection, installation and laying speed have greatly increased its overall cost. The following situations may occur in the application of rigid pipelines:
Lack of flexibility: Rigid pipes, due to their fixed form, lack the ability to bend or stretch, and thus perform poorly in response to external forces such as ground changes, temperature changes, or earthquakes, this may cause the pipe to break or deform.
Susceptibility to stress concentration and fatigue: When rigid pipes are subjected to external loads, the lack of ability to absorb or disperse stress may lead to stress concentration in certain areas. This makes the pipe susceptible to fatigue failure, especially if it is frequently subjected to vibration or shock.
corrosion: Corrosion is a common cause of failure in rigid pipelines, especially metal pipelines. Over time, exposure to moisture, chemicals and other corrosive substances can cause pipelines to deteriorate, leading to leaks and structural weakness.
As a new solution, flexible hoses have important application value in the production and development of offshore oil and gas resources and mineral resources. Its advantages such as bendability, anti-corrosion, installation and laying speed eliminate the limitations of traditional steel pipes, reduce the overall cost, and provide a more efficient and reliable solution. With the continuous development of technology, flexible hoses play an increasingly important role in the offshore resource development industry.
Advantages of flexible hoses:
● As the transported materials flows, the pipeline system will be deformed and expanded under the influence of temperature, pressure and other factors. Flexible hoses can compensate for these deformations and thermal expansion by stretching, bending, etc., so as to ensure the normal operation of the pipeline system.
● Flexible hose can reduce the vibration and noise generated by the fluid in the pipe system, ensuring the normal operation of the pipe and ancillary equipment.
● Flexible hoses are made of wear-resistant elastic material, and the cover of hoses can withstand high external temperature, prolonged UV exposure, and movement.
● Flexible hoses can be easily connected and disconnected, making the maintenance of the pipe system more convenient and efficient. Flexible hoses have high flexibility and plasticity, and can adapt to the connection and maintenance needs of various piping systems.
Flexible hose applied in the pipeline system can improve the safety, stability and maintainability of the piping system, and is an indispensable part of the pipeline system.
