Stainless flexible hose DN20, elbow + straight end

Technical specifications of DN20 stainless steel flexible hose with one elbow end and one straight end

In industrial piping layouts with limited installation space or sharp directional changes, using rigid pipe fittings often presents many obstacles. The DN20 stainless steel flexible hose series featuring one elbow end and one straight end is designed to solve this problem. The product helps engineers easily position the pipeline without the need for complex angle elbows, minimizing the number of intermediate threaded connections.

The hose body is constructed from corrugated stainless steel, encased in a braided outer layer for strength. This design provides high flexibility, allowing for bending within standard radii while maintaining stability against the operating pressure of the fluid. The multi-directional elasticity helps thoroughly absorb vibrations generated by pumps or thermal expansion within the system.

Material specifications and media compatibility

The durability of the equipment depends heavily on selecting the correct steel grade suitable for the actual working environment. The Tan Dat manufacturing workshop offers material options to meet diverse technical requirements:

• Stainless steel 304: The standard choice for clean water systems, compressed air, petroleum, and solutions with low corrosivity.
• Stainless steel 316: Recommended for chemical environments, high-pressure steam, or coastal areas with high salinity.

The operating temperature range of the hose is very broad, maintaining stability across a wide temperature spectrum, depending on the material and connection type. Every product before leaving the Tan Dat fabrication workshop in Ho Chi Minh City undergoes hydraulic pressure testing and strict visual inspection to ensure high safety when put into operation.

Selection guide and installation notes for stainless steel flexible hoses

To ensure maximum service life for the piping system, engineers should note several technical principles during the design and construction process:

1. Length calculation: Do not overstretch the hose or allow it to twist (torsion) when tightening the threads. The hose length must have sufficient slack to perform its vibration absorption function.
2. Bending radius: When shaping the curved section (one elbow end), the minimum bending radius recommended by the manufacturer must be followed to avoid flattening the internal corrugated waves.
3. Connection type selection: Accurately determine the thread pitch of the straight and elbow ends (BSP, NPT, or other standards) to ensure a reliable match with the equipment, avoiding leaks due to thread pitch mismatch.
4. Periodic maintenance: Inspect the braided surface and the connection welds after long periods of operation to detect early signs of wear or chemical corrosion.
