Dongfeng Xinjiang truck parts intercooler air outlet Steel pipe 1119012-T5WFG1Y

Built to maximize airflow efficiency between the intercooler and engine, this steel pipe features a smooth internal structure and optimized fluid dynamics. The inner surface (Ra ≤ 1.6μm) is precision-polished to minimize airflow resistance, reducing pressure loss by 18% compared to aftermarket pipes with rough interiors. Its 54mm inner diameter ensures a maximum airflow rate of 320m³/h, matching the air demand of Dongfeng Xinjiang’s 460hp and 520hp diesel engines. The 135° elbow is designed with a gradual curvature (radius 120mm) to avoid airflow turbulence, maintaining consistent pressure (≤0.2bar pressure drop at full load). By delivering cooled, dense air to the combustion chamber, the pipe enhances fuel combustion efficiency by 12%, increasing engine power output by 5-8% and reducing fuel consumption by 3-5% under heavy-haul conditions

Engineered to endure the high-pressure operating environment of turbocharged intake systems (typical working pressure: 0.8-1.2bar, peak pressure: 2.0bar), the pipe is fabricated from 304 stainless steel with a minimum tensile strength of 515MPa and yield strength of 205MPa. The seamless manufacturing process eliminates weld seams (a common failure point in welded pipes), ensuring uniform structural strength. Key stress points—such as the elbow and flange connections—are reinforced with 6mm-thick reinforcing rings, which distribute pressure evenly and prevent deformation. In pressure cycle tests (100,000 cycles of 0-1.5bar pressure), the pipe shows no signs of leakage or structural damage. This robust design ensures reliability even under extreme conditions, such as turbocharger surges or high-load climbing scenarios

Designed to resist corrosion from road salt, moisture, and engine emissions—major threats to intake system components—the steel pipe features a comprehensive three-layer anti-corrosion system. First, a zinc phosphate pretreatment layer (12μm) forms a rust-inhibiting base on the 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 and road deicers. Finally, a clear acrylic topcoat 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, preventing thread rust and enabling easy disassembly during maintenance

Optimized for efficient installation in commercial truck maintenance, the pipe features precision manufacturing and user-friendly design elements. All dimensions are machined to tight tolerances (outer diameter ±0.1mm, length ±2mm), ensuring perfect alignment with the intercooler and intake manifold without forced fitting. The flared ends are pre-coated with high-temperature sealant (resistant to 200℃), eliminating the need for additional gasket sealants and reducing installation time. 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 30 minutes or less. The pipe is marked with part numbers and installation direction labels (“INTERCOOLER SIDE”) to prevent incorrect fitting, ensuring the intake system’s performance is maintained on the first attempt, minimizing truck downtime for fleet operators
