application
- High-efficiency fluid diversion: Specifically designed for changing the flow direction in pipeline systems, such as chemical plant process pipelines, thermal networks, and oil pipelines, to achieve a smooth 90-degree turn.
- Low-resistance system: Suitable for scenarios requiring smooth fluid flow (such as pump inlets and outlets, main pipeline branches), reducing pressure loss and improving transportation efficiency.
- Suitable for harsh conditions: Corrosion-resistant materials (carbon steel/stainless steel) versions are available for use in chemical, marine, high-temperature, and other corrosive or extreme environments.
- Full size coverage: Supports ½-inch to 24-inch pipes (DN15-DN600), meeting the needs of small equipment to large pipe networks.
advantages
- Streamlined Zero-Loss design -> long-radius bends (1.5 diameters) which reduces turbulence by significant margins, thus lower energy requirement consumption and longevity of the life of pumps & valves
- Good anti-corrosion: carbide/stainless steel with surface treatment (after acid pickling/galvanized) alkali salt anti-corrosion ability, extension of product life by 2 times.
- No leakage hazard: Pipe butt welding completely integrates the pipeline, prevents interface leakage, and is safe to transport hazardous media.
- Permanent system: Welded connections do not need regular maintenance to retighten and, therefore, will have a lower long-term operational cost.
- Broad application range: In line with international standards (ISO/ASME), compatible with global mainstream pipe system.
- Resistant to high pressure and temperature: Meets the line pressure, suitable for severe environments like steam hot oil..
packing
- Rust-proof and impact-resistant packaging:
- Each item is wrapped in rust-proof film + foam corner protectors and placed in a thick corrugated cardboard box (marked: 90° elbow, 6 inches, long radius) .
- Stainless steel products are additionally coated with a scratch-resistant layer.
- Customized solutions for large sizes:
- For 8 inches and above, custom wooden pallets are used, with foam molding securing the curved sections of the elbows to prevent deformation during transportation.
- Efficient ocean freight loading:
- Small sizes are packed in nested boxes, while large sizes are loaded individually on wooden pallets, increasing container space utilization by 40%.
