Dongfeng kinland Metal hose bellows assembly 1202010-X0100

The Dongfeng Kinland Metal Hose Bellows Assembly 1202010-X0100 features a corrugated bellows core, meticulously formed from thin-walled stainless steel (304 or 316 grade) through hydraulic or mechanical shaping. This bellows design delivers exceptional flexibility, allowing axial, lateral, and angular movement (up to ±5mm axial displacement, ±3mm lateral offset, and ±10° angular deflection) to absorb vibrations and compensate for thermal expansion in Dongfeng Kinland’s engine or exhaust systems. Unlike rigid metal pipes, the bellows structure reduces stress on connected components (e.g., turbochargers, exhaust manifolds) caused by engine vibration or temperature fluctuations, minimizing the risk of cracks or leaks. The bellows’ uniform corrugation pattern also ensures consistent flow resistance, maintaining stable fluid or gas transfer (e.g., coolant, exhaust gases) across the assembly

PRODUCT DESCRIPTION

01

High-Grade Metal Construction for Durability & Corrosion Resistance​

Crafted from premium stainless steel (304 for standard applications, 316 for enhanced corrosion resistance), the 1202010-X0100 assembly offers exceptional durability in harsh operating environments. The stainless steel material resists rust, oxidation, and chemical erosion from road salt, coolant, or exhaust byproducts—critical for undercarriage or engine bay installations in Dongfeng Kinland trucks. The bellows’ surface is further treated with a passivation layer to enhance corrosion resistance, extending the assembly’s service life to over 150,000 kilometers under standard use. Additionally, the assembly’s end fittings (flanges or quick-connect ports) are made of forged carbon steel with a zinc-plated finish, ensuring high tensile strength (up to 600 MPa) and secure attachment to the truck’s existing piping system

02

OEM-Specific Fit for Dongfeng Kinland Systems​

Exclusively engineered for Dongfeng Kinland heavy-duty trucks, the 1202010-X0100 metal hose bellows assembly adheres to strict OEM dimensional and performance standards. Its length, diameter (typically 30-50mm inner bore), and end fitting configurations are precision-machined to match the truck’s engine coolant, exhaust, or hydraulic system routing—ensuring seamless integration without modifications to the vehicle’s existing structure. The assembly’s end fittings feature pre-drilled holes or threaded connections that align perfectly with Dongfeng Kinland’s factory mounting points, enabling direct replacement during maintenance. This OEM compatibility guarantees consistent performance, avoiding issues such as misalignment or flow restriction that can occur with generic aftermarket parts

03

Leak-Proof Sealing & Pressure Resistance​

Designed to prevent fluid or gas leakage, the 1202010-X0100 assembly incorporates multiple sealing mechanisms. The bellows’ corrugations are welded using TIG (Tungsten Inert Gas) welding, creating a hermetic seal that eliminates leak paths. The end fittings are brazed or welded to the bellows with precision, ensuring a tight bond that withstands high operating pressures (up to 1.5 MPa for coolant systems, 0.8 MPa for exhaust applications). Additionally, the assembly may include a flexible metal braid outer layer (depending on application) that provides additional pressure reinforcement and protects the bellows from external damage (e.g., road debris). These features ensure the assembly maintains a leak-proof seal even under extreme conditions, such as high temperatures (up to 400°C for exhaust use) or pressure fluctuations

04

Multi-Application Versatility & Compliance​

The Dongfeng Kinland Metal Hose Bellows Assembly 1202010-X0100 is versatile, suitable for multiple systems in Dongfeng Kinland trucks, including engine coolant circulation, exhaust gas recirculation (EGR), and hydraulic fluid transfer. It meets global industry standards, such as ISO 10380 (metal hoses for fluid power), DIN 2817 (industrial metal bellows), and SAE J2006 (automotive coolant hoses), ensuring compliance with safety and performance requirements. The assembly undergoes rigorous testing, including pressure burst tests (1.5x rated pressure), leak tests (helium leak detection, with a maximum leak rate of 1x10⁻⁹ mbar·L/s), and thermal cycling tests (-40°C to 400°C for 500 cycles). By adhering to these standards, the assembly ensures reliable operation across diverse applications, reducing the risk of system failures that could disrupt truck performance
