application
- Used in pipeline systems where a smooth change in fluid direction (45°) is required, ensuring low flow resistance and minimizing turbulence.
- Suitable for systems that emphasize energy efficiency, such as HVAC, water supply systems, chemical processes, and low-pressure steam pipelines.
- Ideal for applications where reducing the impact of flow resistance on system efficiency is critical.
advantages
- Fluid Optimization Design: Long radius structure (R=1.5D) achieves smooth flow, significantly reducing turbulence, pressure drop, and energy loss.
- High Sealing Connection: Provides excellent sealing and structural strength for welded joints, suitable for high integrity piping systems.
- Corrosion-Resistant Materials: Offers carbon steel (S235/P235TR2) and stainless steel (WP304/WP316L equivalent) options, suitable for corrosive/clean environments.
- Low maintenance costs: Smooth fluid characteristics extend system lifespan and reduce maintenance requirements.
- Surface protection processes: Supports black coating, hot-dip galvanizing, or acid washing and whitening treatments to enhance durability.
- Pressure reliability: Pressure-bearing capacity is consistent with that of straight pipe sections of the same specification.
- Wide compatibility: Covers standard industrial pipe sizes from 1 inch to 24 inches (NPS).
packing
- Export Standard Reinforcement Packaging: Carried in wooden cases or restraint boxes to prevent damage due to collision.
- Small-size packaging- Thickened carton boxes with internal filler materials.
- Protective measures:Plastic caps/plugs are installed on pipe openings, and the surface is wrapped in rust-proof oil paper.
- Clear labeling:Label with product name, dimensions, material, quantity, and warning labels (e.g., “Fragile,” “Keep Dry”).
