Dongfeng Xinjiang truck spare parts Turbocharger intake pipe 1109026-T5WFC1Y

Built to maximize airflow efficiency from the air filter to the turbocharger, this intake pipe features a precision-optimized internal structure. The inner surface undergoes fine polishing treatment, achieving a roughness of Ra ≤ 1.0μm to minimize airflow resistance—reducing pressure loss by 22% compared to aftermarket pipes with rough, unprocessed interiors. Its 52mm inner diameter ensures a maximum airflow rate of 310m³/h, perfectly matching the air demand of 520-560hp high-performance engines. The 105° elbow is designed with a gradual curvature (radius 110mm) to avoid airflow turbulence, maintaining consistent pressure (≤0.17bar pressure drop at full load). By delivering unobstructed, high-volume air to the turbocharger’s compressor, the pipe enhances compressor efficiency by 10%, boosting turbo response time by 8% and ensuring denser air enters the combustion chamber to improve power output and fuel economy

Engineered to endure the harsh operating environment of turbocharged intake systems (typical working pressure: 1.0-1.4bar, peak pressure: 2.3bar during turbo surges), the pipe is fabricated from seamless 304 stainless steel with a minimum tensile strength of 515MPa and yield strength of 205MPa. The seamless manufacturing process eliminates weld seams—common failure points in welded pipes—ensuring uniform structural strength across the entire length. Key stress points, including the elbow and flange connections, are reinforced with 5mm-thick stainless steel collars that distribute pressure evenly and prevent deformation. In pressure cycle tests (100,000 cycles of 0-1.7bar pressure), the pipe shows no signs of leakage or structural damage. It also resists thermal expansion/contraction during engine startup/shutdown, avoiding cracks that could lead to catastrophic turbo failure

Designed to resist corrosion from road salt, moisture, and engine contaminants—major threats to underhood intake components—the pipe features a comprehensive three-layer anti-corrosion system. First, a zinc phosphate pretreatment layer (10μm) forms a rust-inhibiting base on the stainless steel surface. Then, a high-temperature electrostatic powder coating (80-90μm, epoxy-polyester composite) is applied, creating a scratch-resistant, waterproof barrier that resists chemical erosion from diesel exhaust residues and road deicers. Finally, a clear chromate passivation layer enhances UV resistance and gloss retention. The pipe passes 1500-hour salt spray testing (ASTM B117) with no red rust, ensuring durability for over 8 years in coastal areas, snowy regions, or construction site environments. The flange mounting holes are plated with 10μm-thick tin to prevent thread rust and ensure easy disassembly during maintenance

Optimized for efficient maintenance in commercial truck fleet operations, the pipe features tight-tolerance machining and user-friendly design elements. All dimensions are machined to strict tolerances (outer diameter ±0.1mm, length ±2mm), ensuring perfect alignment with the turbocharger and air filter without forced fitting. The flared ends are pre-coated with high-temperature butyl rubber sealant (resistant to 200℃), eliminating the need for additional gasket sealants and reducing installation time by 30%. The package includes 4 M8×25 galvanized bolts (grade 8.8) and lock washers, matching the original torque requirements (28-32N·m). Installation requires only a standard torque wrench—no specialized welding or cutting tools needed—and a single technician can complete the replacement in 35 minutes or less. Clear labeling (“AIR FILTER SIDE” and “TURBOCHARGER SIDE”) prevents incorrect fitting, ensuring the intake system’s performance is maintained on the first attempt, minimizing truck downtime for fleet operators
