application
- Used in pipeline systems for 180° complete reverse turns, enabling efficient fluid return flow or compact pipeline design.
- Suitable for applications requiring large angle turns and a reduction in the number of raccords de tuyauterie, such as heat exchanger connections, pump group circuits, chemical reaction equipment, and long-distance pipeline turning systems.
- Replaces multiple elbow combinations in scenarios where space is limited but low flow resistance must be ensured.
avantages
- Optimization of fluid dynamics: Furthermore, the long radius structure (R=1.5D) effectively decreases turbulence and pressure drop to save the system energy consumption.
- All-in-one high-strength design: No leakage butt-welded connections through out and enhance whole structure tight, eliminate weak points by multiple elbow joints.
- Material Corrosion resisistant Double-side T-joint: For carbon steel (S235/P235TR2) and stainless steel (e.g. wP304/WP316L) according to the operational requirements.
- Saving instalments of costs: Middle turning through 180° by a single component equals less number of welding point and simpler installation.
- Surface protection process: meet black paint spray, hot dip galvanizing or acid washing passivation treatment to enhance environmental resistance.
- Pressure compatibility: the pressure has the same capacity to bear as that of straight tubes of similar specification, with no increase in strength loss.
- Wide range applications: Full size coverage from 1 inch to 24 inches (NPS) and a large variety of sizes for ERW Straight Seam Steel Pipe, Spiral Welded Steel Pipe has wide market opportunities.
emballage
- Heavy-duty protective packaging: Reinforced wooden boxes or multi-layer plywood boxes are used, with internal cushioning materials to prevent vibration and impact.
- Tube End Protection: Engineering plastic caps are installed at both ends to prevent deformation from impacts during transportation.
- Rust Prevention Treatment: The surface is wrapped in vapor-phase corrosion inhibitor (VCI) paper or coated with rust-preventive oil.
- Labeling Standards: The outer box is clearly labeled with product name, angle, material, dimensions, and orientation markers such as “↑Upward.”
