Flexible stainless steel hoses are essential materials for modern industry. However, the quality of metal hose pipes varies widely on the market. So, how can you select a high-quality flexible steel hose? Here are some key tips:
1. Examine the Weaving Effect of the Tube Body
Start by inspecting the hose’s weaving pattern. The tube body should have no visible jumps, breaks, or overlapping strands. In general, a higher interweaving density indicates better quality. Additionally, check the spacing between steel wires: smaller gaps typically mean a more durable and reliable metal hose.
2. Verify the Stainless Steel Material Grade
Next, confirm that the tube body is made of genuine stainless steel. The corrosion resistance of the hose depends on the stainless steel grade—higher grades offer better durability. A simple way to test this is by using a stainless steel identification potion. For example, 304 stainless steel wire is a high-end choice commonly used in premium hoses.
3. Check Other Components’ Materials and Quality
Don’t overlook the hose’s auxiliary parts:
Nuts and cores
Ensure they are made of copper fittings. High-quality copper nuts are usually polished and chrome-plated for corrosion resistance.
Surface finish
Inspect for burrs, scratches, or uneven plating on all metal components.
Steel sleeves
Use the same stainless steel identification method to confirm if the sleeve is made of 304 material. Higher-grade materials ensure longer lifespan.
4. Understand Joint-Related Quality Considerations
Note: If a hose separates at the joint or fails within 25mm of the connection during use, this is typically a joint-related issue—not a flaw in the hose itself. Always ensure joints are properly installed and matched to the hose’s specifications.
