Agricultural Machinery High-Temperature Resistant Ductile Iron Exhaust Pipe (EN-GJS-Si4 / EN-GJS-Si5 / EN-GJS-Si4Mo)
The agricultural machinery high-temperature resistant ductile iron exhaust pipe is a core exhaust component of the power system for agricultural machinery such as tractors, harvesters and agricultural engines. Specifically designed for the high-temperature, high-vibration and dusty field working environment of agricultural machinery engines, its core function is to efficiently discharge high-temperature exhaust gas after engine combustion, and at the same time achieve noise reduction, heat insulation and guide exhaust gas flow, ensuring normal heat dissipation and stable operation of the engine. It is a key supporting accessory for agricultural machinery power output, widely applicable to various small, medium, and medium-heavy agricultural machinery equipment.
Material: Selected European Standard High-Temperature Resistant Ductile Iron EN-GJS-Si4, EN-GJS-Si5, EN-GJS-Si4Mo; all three are special heat-resistant materials for agricultural machinery exhaust pipes. After special high-temperature strengthening treatment, a dense anti-oxidation protective film is formed on the surface, which can stably withstand medium and high-temperature working conditions for a long time, meet the different exhaust temperature requirements of agricultural machinery engines, no frequent replacement, and balance heat resistance, toughness and practicality, accurately matching different operation intensities:
European Standard EN-GJS-Si4: Silicon content 3.0%~4.0%, excellent high-temperature resistance, can stably withstand ≤650℃ high-temperature working conditions for a long time. It has good toughness, strong impact resistance and vibration resistance, can flexibly cope with the high and low temperature alternating impact when the engine starts and stops, suitable for conventional operations of medium and light agricultural machinery, with outstanding cost performance, and is the mainstream selection for agricultural machinery exhaust pipes.
European Standard EN-GJS-Si5: Silicon content 4.5%~5.5%, more excellent high-temperature resistance, can stably withstand ≤700℃ high-temperature working conditions for a long time. It has stronger oxidation resistance and heat growth resistance, resistance to exhaust gas corrosion and thermal fatigue, suitable for medium-sized agricultural machinery and long-time continuous operation scenarios, especially for agricultural machinery with high engine exhaust temperature, with longer service life.
European Standard EN-GJS-Si4Mo: Silicon content about 4.0%, added molybdenum (0.5%~0.9%), upgraded high-temperature resistance, can stably withstand ≤750℃ high-temperature working conditions for a long time. On the basis of EN-GJS-Si4, it greatly improves creep resistance and thermal deformation resistance, with better impact resistance and vibration resistance. It is suitable for medium-heavy agricultural machinery, high-temperature heavy-load and frequent start-stop working conditions, such as large harvesters and heavy tractors, effectively avoiding high-temperature cracking and deformation of the exhaust pipe, and is the preferred material for high-temperature heavy-load agricultural machinery.
Adopting precision casting and CNC precision machining technology, the pipe body has a reasonable structure, uniform wall thickness, and smooth exhaust channel, which effectively reduces exhaust resistance and helps improve engine power output efficiency; the interface has high dimensional accuracy, fits closely with the exhaust port of agricultural machinery engines, and has reliable sealing performance, which can effectively prevent high-temperature exhaust gas leakage, reduce noise pollution and heat loss; the surface is specially treated with high-temperature rust and corrosion resistance, resistant to field sediment and dust erosion, resistant to high and low temperature alternating impact, not easy to rust, crack or age, suitable for various harsh field working environments, and easy to maintain.
It has strong compatibility, can match mainstream agricultural machinery engine models around the world, supports customization of exhaust pipe length, caliber, interface specifications and non-standard structures according to customer needs, and adapts to the exhaust needs of agricultural machinery with different powers; the quality strictly complies with European standard testing standards, with up-to-standard materials and stable performance, suitable for foreign trade export, timely supply and reliable quality, effectively solving the industry pain points of agricultural machinery exhaust pipes being easily damaged at high temperatures and having a short service life.
