Qingdao Desu Machinery Equipment Co., Ltd.

Lightweight yet High-Strength: With a density only 1/3 that of steel, aluminum alloy pipes can achieve high strength through alloying treatment (e.g., 6061-T6), boasting a compressive capacity of up to 16 bar. Corrosion Resistance: The surface oxide film provides effective rust prevention, making them suitable for humid or chemical industry environments. Energy Efficiency: Featuring a smooth inner wall (with a roughness of 0.03 mm), they have a pressure drop loss 40% lower than that of traditional steel pipes. Easy Installation: The crimp-type quick-installation system supports zero welding, improving installation efficiency by 70%. Long Service Life: The design life reaches 50 years, with a 10-year warranty period. Wide Temperature Resistance: The operating temperature ranges from -20℃ to +80℃, and some models can withstand high temperatures of up to 150℃.

Corrosion Resistance: A dense oxide film forms on the surface of stainless steel pipes, which effectively resists erosion by corrosive media such as oxygen and water. Grades like 304L and 316L exhibit excellent performance in chloride-ion-containing environments. Dual-grade stainless steel (e.g., 304/304L) balances strength and corrosion resistance through precise control of carbon and nitrogen content. High Strength and Toughness: Stainless steel pipes possess high tensile strength and yield strength. The yield strength of dual-grade stainless steel can be nearly twice that of ordinary 304L stainless steel, enabling a 30%-50% reduction in equipment wall thickness. Low-temperature-grade dual-grade stainless steel maintains good toughness even at -40°C. Environmental Friendliness and Health Safety: Stainless steel pipes are non-toxic and odorless, complying with drinking water transportation standards. Grades such as 304/304L are widely used in direct drinking water systems to ensure water quality safety.

High Corrosion Resistance: U-PVC has excellent resistance to chemical media such as acids and alkalis, making it suitable for corrosive environments. Hygienic and Non-Toxic: It complies with food-grade standards and is applicable to scenarios with high hygiene requirements, such as the food industry and drinking water systems. Light Weight: With low density, it is convenient for installation and maintenance. Structure and Maintenance: It is easy to disassemble. Adopting double union socket connections or gear-driven actuators, it supports both manual and automatic operation modes, enabling simple maintenance. Wear Resistance: Both the valve body and valve core are made of U-PVC material, which has good wear resistance and is suitable for the transportation of particle-containing media.

Piping Selection and Materials Stainless Steel Pipes: Made of 304/316L material with polished inner walls, suitable for high-cleanliness scenarios (e.g., food industry, pharmaceutical industry). Aluminum Alloy Pipes: Featuring lightweight design, their compressive strength is 1.8 times that of traditional steel pipes, making them ideal for long-distance transportation. Low-Pressure U-PVC Pipes: Cost-effective, but regular inspection of inner wall corrosion is required. II. Design Specifications and Maintenance Pressure Matching: The pressure resistance grade of the pipeline must be 1.5 times higher than the maximum output pressure of the air compressor (e.g., a 1.2MPa pipe is selected for a 0.8MPa system). Leak Detection: It is recommended to use an ultrasonic detector or a combination with gooseneck pipes to locate hidden leak points. Annular Loop Design: Ensures stable pressure at air consumption points and reduces pressure drop.
