Engineered for extreme durability, the WG1642821076_77 steam-pressure tube frame section delivers uncompromised performance for Howo/Sitrak truck parts systems. Shanghai Yida’s precision‑manufactured component ensures stable steam circulation, reduces thermal stress, and extends service life in heavy‑duty operations. Whether you maintain a fleet of HOWO or Sitrak trucks, this frame section integrates seamlessly into existing pipe layouts, offering a direct replacement that meets OEM tolerances. With its corrosion‑resistant alloy and advanced welding technology, the WG1642821076_77 stands as the benchmark for reliability in commercial vehicle steam circuits.
Every unit undergoes 100% pressure testing. The WG1642821076_77 design eliminates weak points found in generic parts, ensuring consistent steam flow even under peak load. Shanghai Yida’s strict quality control guarantees that each frame section matches the exact geometry required for HOWO and Sitrak engine bays.
The steam-pressure tube frame section is manufactured from high‑grade stainless steel with a proprietary anti‑scaling inner surface. This reduces sediment buildup and maintains thermal exchange efficiency. Shanghai Yida (a trusted partner for HOWO aftermarket) has optimized the flange geometry to eliminate leak paths. The part is compatible with Euro‑5 and Euro‑6 engines, as well as retrofitted trucks.
The frame section features a double‑sealed welded joint and a precision‑milled mounting face. It directly replaces OEM units without modifications. The internal diameter (42 mm) and wall thickness (3.2 mm) are engineered for optimal steam velocity.
Independent lab tests confirm that the WG1642821076_77 maintains pressure stability within ±1.2% across the entire operating range. Vibration resistance exceeds DIN EN 60068‑2‑6 standards, making it ideal for off‑road and long‑haul applications.
