Description
Technical construction features of the 304 stainless steel double-ended flexible joint
In pressurized piping systems, controlling mechanical vibration and thermal expansion is a critical challenge for design engineers. Our threaded & union flexible joints are engineered to effectively resolve these issues. The device structure features a corrugated inner tube at the center, manufactured from high-quality stainless steel. It is encased in layers of braided stainless steel wire, which prevents the hose from expanding under high-pressure flow. Both ends are machined with double threaded connections, providing maximum flexibility during installation into fixed piping sections.
The flexible nature of the hose allows engineers to easily direct flow and navigate tight corners that rigid pipes cannot handle. Simultaneously, the device fully absorbs vibration amplitudes generated by pumps or moving equipment, preventing weld cracks throughout the pipeline.

Advantages of application in industrial systems
Integrating threaded flexible joints into operating pipelines provides many practical benefits for operators:
- Compensating for installation errors: Corrects misalignment between pipe sections or between pipes and mechanical equipment.
- Noise reduction: Eliminates vibrations transmitted along the pipe body, keeping the workspace stable.
- Optimizing construction time: Threaded connections allow for quick assembly and disassembly, requiring no complex on-site welding.
- Long-term durability: Stainless steel material effectively resists corrosion in humid environments or mild chemical exposure.
Practical application scope
Thanks to its stable performance under varying temperature and pressure conditions, the product is trusted in many fields:
- Hot water pipelines, boilers, and industrial steam boilers.
- Water supply systems for buildings, industrial zones, and fire protection networks.
- Hydropower pumping stations and thermal power plants.
- Technical infrastructure for the oil and gas industry and corrosive fluid processing systems.
Custom fabrication services at the Tan Dat workshop
Every project has unique technical requirements. Our workshop accepts designs and custom fabrication of flexible joints according to your drawings or actual specifications. Factors such as length, thread pitch, and steel grade (304 or 316 stainless steel) are precisely adjusted. All products leaving the factory undergo a strict pressure testing process to ensure high safety during operation.

Frequently asked questions about threaded & union flexible joints
What pressure can the stainless steel flexible joint withstand?
Standard single-braided stainless steel flexible joints operate at PN10 – PN16 (10 – 16 bar). For higher pressure, Tan Dat fabricates double-braided types or increases corrugated hose thickness according to design specifications.
Should I choose 304 or 316 stainless steel flexible joints?
Stainless steel 304 is suitable for most water, steam, and gas systems. Stainless steel 316 contains molybdenum for better corrosion resistance, so it should be used for chemicals, seawater, wastewater, or near-coastal environments.
Does Tan Dat fabricate flexible joints with custom lengths and flange types?
Yes. We manufacture directly, accepting custom fabrication for any length, DN15 – DN300 (larger upon request), JIS, BS, ANSI, DIN flanges, threaded ends, unions, and clamps. Call 0906 304 114 for a quote.

Tan Dat Flex engineering team
304 stainless flexible joint with double nipple ends belongs to our threaded & union flexible joints range. Material: 304 stainless steel (316 on request), end connection: Double nipple. 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
