What are the areas of application for composite casing?

In addition to the important applications in the energy field such as oil and gas extraction and geothermal development, composite casing also plays an important role in many industries such as chemical industry, construction, electric power, water conservancy, etc. The following are some specific application areas:
Energy field
Oil and natural gas extraction: used in oil wells, gas wells casing column, can withstand high pressure, high temperature and corrosive environment downhole, to protect the stability of the well wall, to prevent the leakage of formation fluids, especially for horizontal wells, directional wells and other special wells, which can improve the quality of the well body and mining efficiency.
Geothermal development: it can adapt to the working conditions of high temperature and high mineralization of geothermal wells, extend the service life of geothermal wells and reduce the development cost.
Chemical field
Chemical pipeline: it can transport various corrosive chemical media, such as acid, alkali, salt solution, etc. With its excellent corrosion resistance and wear resistance, it can effectively resist media erosion, reduce the risk of pipeline leakage, and improve the safety and stability of chemical production.
Chemical reactor: as the lining or overall structure material of the reactor, it can withstand high temperature, high pressure and chemical corrosion in the reaction process, which helps to realize various complex chemical reactions and improve reaction efficiency and product quality.
Construction field
Building water supply and drainage pipes: with corrosion resistance, abrasion resistance, smooth inner wall and other characteristics, it can reduce the resistance of water flow, reduce energy consumption, while avoiding rusting and scaling of pipes to ensure water quality, widely used in the internal water supply and drainage system of the building as well as outdoor municipal water supply and drainage projects.
Building structure reinforcement: wrapping concrete columns, beams and other structural components with composite casing can improve the structural carrying capacity, seismic performance and durability, and is commonly used in building reinforcement and renovation projects to extend the service life of buildings.
Ventilation pipe: In the building ventilation system, composite casing can be used as ventilation pipe with good corrosion resistance and heat preservation performance, which can effectively transport air and reduce energy loss at the same time.
Electricity field
Cable protection tube: used to protect power cables, characterized by good insulation, strong corrosion resistance and high mechanical strength, it can prevent the cables from being damaged by external factors, such as mechanical damage, chemical corrosion, etc., to ensure the safety and reliability of power transmission.
Substation bus duct: in the substation, as the bus protection casing, can withstand high voltage and high current, and at the same time has good insulation and heat dissipation performance, to ensure the normal operation of the substation.
Water conservancy field
Irrigation pipeline: In agricultural irrigation, the composite casing can be used as water pipeline, which has the advantages of corrosion resistance, abrasion resistance, anti-aging, etc. It can be adapted to different soil and water quality conditions, reduce the waste of water resources and improve the irrigation efficiency.
Water conservancy and hydropower engineering: used in pressure steel pipe and diversion pipe of hydropower station, etc. It can withstand the impact of high-pressure water flow, and at the same time, it has good anti-fatigue performance and corrosion resistance, which ensures the safe operation of water conservancy and hydropower engineering.
