Daoke Dao Laser Welding for Automotive Fuel Tank Vent Pipes: Corrosion-Resistant & Airtight

Date：2026-01-19 14:41 Source：daokedao Browse：14

Automotive fuel tank vent pipes require corrosion-resistant and airtight welding to ensure fuel vapor management. Traditional pipes easily corrode and leak, violating emission standards. Daoke Dao plastic laser welding equipment ensures vent pipe reliability. Suitable for HDPE and PP materials, the welds resist gasoline vapor and fuel additives, meeting automotive emission standards (Euro 6, EPA). The hermetic weld seam achieves IP67 protection, preventing vapor leakage and air intrusion. The flexible welding path adapts to the pipe’s layout. Compliant with IATF 16949 standards, the equipment integrates into automated fuel system assembly lines, with a welding speed of 1.8m/min. It has passed 1000-hour corrosion tests, ensuring long-term durability. The automated process improves batch consistency. Daoke Dao helps auto fuel system manufacturers. Contact us for emission compliance data.
