13558225 Pipe bend welded assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 13558225 bend welded pipe assembly is a custom-made core pipe connection accessory for the cab, specifically designed for various engineering machinery cabs. It is primarily used for the turning connection and sealing of ventilation and air conditioning ducts, featuring strong welding, leak-proof sealing, and impact resistance. It ensures smooth airflow through the ductwork, is suitable for bumpy operations in mines and construction sites, and prevents pipe connections from falling off, leaking, or breaking, ensuring the stable operation of the cab’s ventilation and air conditioning systems.
This product is an original factory compatible part, precisely matched to the cabs of Sany, XCMG, Caterpillar and other series of construction machinery. Relying on CNC pipe bending and precision welding technology, it is compatible with the original factory pipe installation station and cab pipe layout. It can be quickly installed and welded without complicated debugging. It can withstand bumpy, high and low temperature and dusty and oily working conditions, with tight connection and good sealing.

【Core Technical Parameters】

-Product Model: 13558225
– Product Type: Bend Welded Pipe Fittings (Original Equipment Manufacturer, Special Pipe Steering Connection Welding Accessories for Engineering Machinery Cabs)
– Product Brand: Genuine Original Product (Compatible with various construction machinery cabs, of the same quality, and with guaranteed after-sales service)
– Compatible Models: Suitable for cabs of Sany, XCMG, Caterpillar, and other construction machinery; precisely fits ventilation and air conditioning duct installation positions; compatible with ductwork turning connections in various construction machinery cabs.
-Material: ≥1.0mm thick 201 stainless steel (carbon steel or 304 stainless steel optional), CNC bent and precision welded, surface treated for rust and corrosion prevention, tensile strength ≥520MPa, hardness HRC28-32, tensile strength of welded parts not less than 80% of the base material.
Operating temperature range: -30°C to +120°C (suitable for high-temperature airflow in air conditioning ducts; structurally stable under extreme temperatures; welds do not crack; sealing performance remains unaffected)
– Structural Specifications: One-piece welded structure, including the bend body, welded joint, and sealing groove. Bending angles are selectable at 45° and 90° (to accommodate pipe turning requirements). It combines pipe turning, connection and fixation, and leak-proof sealing functions, conforming to the cab’s pipe layout.
– Dimensions: Precisely fits original factory piping locations; interface diameter, bending radius, and pipe thickness closely match pipe dimensions, perfectly matching cab air ducts and air conditioning ducts. Dimensional tolerances are IT6-IT7 grade, and geometric tolerances meet GB/T 12459-2017 requirements.
-Installation method: Welding + bolt-assisted fixing, compatible with original factory pipe interfaces. Installation requires professional welding tools. After welding, the connection is firm, tightly sealed, and not easy to fall off.
– Protective properties: Waterproof, dustproof, and oil-proof; surface treated for rust and corrosion prevention; salt spray resistance ≥500 hours; wear-resistant, aging-resistant, and UV-resistant; colorfast and non-deformable; welds are sealed with a leakage rate ≤1%.
-Service life: ≥4 years under normal working conditions, ≥2 years under harsh working conditions; no deformation or cracking after passing tests for resistance to bumps, high and low temperatures, and weld fatigue; can withstand 15 impacts of a 147m/s² half-sine wave without significant deformation.

Whether in bumpy environments, dusty mines, or extreme temperatures, this product consistently performs its functions of pipe bending and sealing, ensuring smooth and leak-free airflow in the cab’s ventilation and air conditioning ducts, improving driving comfort and reducing maintenance costs. Original factory compatible and traceable with a unique code, it is a high-quality genuine part for the repair, replacement, and bulk stocking of bent pipe welded components for construction machinery cabs.
