Description
Technical guide for selecting threaded stainless steel flexible hoses for piping systems
When designing industrial or civil piping networks, eliminating stress caused by thermal expansion and reducing vibrations from pumps is a core challenge. Threaded & union flexible hoses manufactured directly by the Tan Dat mechanical workshop in Ho Chi Minh City are an effective technical solution for connecting small-diameter pipe sections where welding is not convenient.
Material properties and basic technical specifications
To ensure durability in harsh working environments, selecting the correct steel grade and connection type is decisive. Engineers need to be well-versed in the standard technical specifications of this product line:
- Manufacturing material: Standard use of 304 stainless steel, or optional 316 stainless steel according to specific project requirements to increase resistance to chemical corrosion.
- Connection type: Diverse options including male or female threads, convenient for direct tightening onto valves, fittings, or existing pipelines.
- Hose length: Flexible for cutting and fabrication according to the exact dimensions of the construction drawings.
- Factory inspection: 100% pressure testing and visual inspection of products before handing over to the installation unit.
Technical criteria for selecting threaded flexible hoses
Before ordering fabrication, the on-site technical team needs to accurately determine the following factors to ensure long-term operational durability:
- Displacement amplitude: Calculate the thermal expansion distance of the system to choose the appropriate corrugated hose length, avoiding excessive tension or kinking of the hose.
- Fluid medium: Clearly identify the liquid, gas, hot steam, oil, or chemical solution running inside the hose to select the compatible stainless steel type, limiting surface pitting or stress corrosion.
- Working pressure and temperature: Compare the system's design parameters with the pressure-bearing capacity of the threaded ends and the flexible hose.
Practical applications in industrial systems
Thanks to their vibration-damping and heat-resistant properties, threaded stainless steel flexible hoses are widely used in many factories and infrastructure projects:
- Water supply and drainage systems, municipal and factory wastewater treatment.
- Pipelines for air, gas, fuel oil, and common chemicals.
- Fire protection (PCCC), HVAC, and refrigeration systems.
- Machine manufacturing, metallurgy, cement, paper, and textile dyeing plants.
- Shipbuilding, hydropower, and thermal power plants.
Custom fabrication process for flexible hoses at Tan Dat workshop
Each project has unique installation space requirements; therefore, fabrication according to drawings is the optimal choice for contractors. The Tan Dat production workshop quickly meets requirements for non-standard dimensions, special thread pitches, or high-acid-resistant materials. All products undergo rigorous hydraulic pressure testing to completely eliminate leakage risks before being put into actual operation.

Frequently asked questions about threaded flexible hoses
What temperature can stainless steel flexible hoses withstand?
Stainless steel 304/316 flexible hoses can withstand much higher temperatures than rubber hoses; the actual limit depends on the fittings, gaskets, and working pressure. Please let us know the temperature and medium to choose the appropriate configuration.
Can stainless steel flexible hoses be used for gas, gasoline, and oil?
Yes. Braided stainless steel flexible hoses are leak-tight, non-aging, and commonly used for conveying LPG, gasoline, oil, and hydraulic oil. For highly corrosive chemicals, PTFE hoses with stainless steel braid should be used.
What sizes of stainless steel flexible hoses does Tan Dat fabricate?
From DN15 to DN60 with female cone seat thread, male/female thread, or union ends; larger sizes with flanges upon request, and custom lengths.

Tan Dat Flex engineering team
Threaded hose connectors – all thread types belongs to our threaded flexible hoses range. Material: 304 stainless steel (316 on request), end connection: Female / male thread. Our engineers recommend it when you need this: compact threaded ends install directly without welding, ideal for small bore lines. For the longest service life, choose the right specification and follow the installation guide.
Strengths
- Compact threaded ends install directly without welding, ideal for small bore lines
- Absorbs axial thermal expansion and reduces stress on welds, supports and equipment
- Isolates vibration from pumps, compressors and chillers, reducing weld cracks and pipe noise
- Durable stainless steel that withstands heat and rust in normal service
- Made to order in the size, end connection and material your project needs
Selection & installation notes
- Check the thread standard (BSP/NPT) and use a sealant suited to the medium
- Movement must be calculated and guides/anchors installed correctly for stable operation
- Install as close as possible to the vibration source; do not use the joint to correct large misalignment
- When ordering, share pressure, temperature, medium and installation size for an accurate quotation
