Large caliber sandwich composite pipe is a pipeline composed of sandwich material and composite material. It is suitable for liquid or gas transportation under large caliber, high pressure, and special working conditions.
Sandwich material refers to a strong fiber material made by weaving or weaving, such as high-strength polyester or nylon fibers. These fiber materials have good tensile strength and wear resistance, which can enhance the structural strength and compressive strength of pipelines.
Composite materials are usually composed of polymers (such as epoxy resin, glass fiber reinforced resin) and filling materials (such as glass fiber, carbon fiber, silicate, etc.). Composite materials have the characteristics of lightweight, high strength, and corrosion resistance, which can improve the pressure resistance and corrosion resistance of pipelines.
Large caliber sandwich composite pipes have the following characteristics:
1. High strength: The combination of sandwich material and composite material enables the pipeline to have high tensile strength and pressure resistance, and can withstand large internal and external pressures.
2. Corrosion resistance: Composite materials have excellent corrosion resistance and can resist the erosion of various chemical media, making them suitable for the transportation of corrosive liquids or gases.
3. Lightweight: Compared to metal pipes, sandwich composite pipes are lighter in weight, making them easier to transport and install, reducing engineering costs and human resource consumption.
4. Long service life: The sandwich composite pipe can work stably for a long time in harsh environments and high pressures, and has a long service life.
5. Easy installation: The installation of sandwich composite pipes is usually done using flange connections or rubber sealing ring connections, which are easy and fast to install without the need for complex welding or fixing.
Large caliber sandwich composite pipes are widely used in large-scale pipeline engineering in the fields of petroleum, natural gas, chemical, and power, such as oil pipelines, natural gas pipelines, and chemical plant pipelines. It has excellent performance under long-distance transportation, high pressure, and high temperature conditions, providing reliable transportation guarantee for industrial production.
