Dongfeng xinjiang truck parts intercooler Intake steel pipe 1119011-T5WFC1Y

Built to maximize airflow efficiency between the turbocharger and intercooler, this steel pipe features a precision-optimized internal structure. The inner surface undergoes fine polishing treatment, achieving a roughness of Ra ≤ 1.2μm to minimize airflow resistance—reducing pressure loss by 20% compared to aftermarket pipes with rough interiors. Its 50mm inner diameter ensures a maximum airflow rate of 290m³/h, perfectly matching the air demand of 460-520hp engines. The 90° elbow is designed with a gradual curvature (radius 100mm) to avoid airflow turbulence, maintaining consistent pressure (≤0.18bar pressure drop at full load). By delivering high-volume, unobstructed air to the intercooler, the pipe enhances heat dissipation efficiency by 12%, ensuring cooler, denser air enters the combustion chamber to boost power and reduce fuel consumption

Engineered to endure the high-pressure operating environment of turbocharged intake systems (typical working pressure: 0.9-1.3bar, peak pressure: 2.2bar), 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 across the entire length. Key stress points—such as the elbow and flange connections—are reinforced with 5mm-thick stainless steel rings, which distribute pressure evenly and prevent deformation. In pressure cycle tests (100,000 cycles of 0-1.6bar pressure), the pipe shows no signs of leakage or structural damage, ensuring reliability even during turbocharger surges or high-load climbing scenarios

Designed to resist corrosion from road salt, moisture, and engine contaminants—major threats to intake system components—the steel pipe features a comprehensive three-layer anti-corrosion system. First, a zinc phosphate pretreatment layer (10μm) forms a rust-inhibiting base on the steel surface. Then, a high-temperature electrostatic powder coating (85-95μm, epoxy-polyester composite) is applied, creating a scratch-resistant, waterproof barrier that resists chemical erosion from diesel exhaust 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

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 intercooler 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 (25-30N·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 (“TURBOCHARGER SIDE” and “INTERCOOLER SIDE”) prevents incorrect fitting, ensuring the intake system’s performance is maintained on the first attempt
