Description
Technical guide on selecting and using threaded, union, and sanitary clamp stainless steel flexible joints at Tan Dat
In industrial piping systems, managing vibration from pumps and compensating for installation misalignment are decisive factors for the lifespan of the entire pipeline. The Tan Dat mechanical workshop in Ho Chi Minh City specializes in manufacturing and supplying stainless steel flexible joints with threaded, union, and clamp connections that meet strict technical standards for various practical projects.
Technical specifications and manufacturing materials
To ensure durability in harsh working environments, engineers often focus on the materials that make up the product. The Tan Dat fabrication workshop uses two primary grades of stainless steel:
- Stainless steel 304: Suitable for clean water systems, compressed air, light oil, and general environments due to its excellent oxidation resistance.
- Stainless steel 316: The optimal choice for pipelines carrying chemicals, highly corrosive solutions, or high-pressure steam environments.
The non-magnetic properties of the material help the product maintain long-term mechanical stability. Actual pressure testing and visual inspection are performed on 100% of products before they leave the Binh Hung Hoa factory.
Classification of common threaded, union, and clamp connection types
Depending on the design of industrial valves or pumps, operating engineers can choose from the following compatible connection types:
- Union type: Consists of a flexible hose combined with two BSPT female threaded ends, making it convenient to screw directly into the pipeline and facilitating disassembly during maintenance.
- Male/Female thread type: Available in common sizes (13, 17, 21, 27, 34mm, etc.) with convex or female cone seat thread, meeting the needs of various tight spaces.
- Clamp type: Specialized for systems requiring high tightness, clean surfaces, and easy assembly/disassembly using quick-release clamps.
Practical applications in piping systems
Thanks to the flexible hose structure combined with an outer braided layer, the product effectively acts as a vibration damper, preventing pipe cracking due to pressure shocks or thermal expansion. Typical installation areas include:
- Urban water supply and drainage systems and wastewater treatment pumping stations.
- Steam and heat transfer oil pipelines in manufacturing plants.
- Fire protection (PCCC) systems and central air conditioning (HVAC).
- Food technology and basic chemical production lines.
Custom fabrication services and technical consultation
Each piping system has its own specific requirements regarding space and operating parameters. The Tan Dat Mechanical Workshop accepts custom fabrication based on drawings or specific requirements for length, thread pitch, pipe diameter, and stainless steel material for each project. Engineers and partners needing detailed advice on technical solutions, pressure parameters, or a quote for manufacturing flexible joints, please contact us directly for prompt support.
Frequently asked questions about threaded & union flexible joints
What pressure can stainless steel flexible joints withstand?
Common single-braided stainless steel flexible joints operate at PN10 – PN16 (10 – 16 bar). For higher pressures, Tan Dat fabricates double-braided types or increases the corrugated hose thickness according to design specifications.
Should I choose stainless steel 304 or 316 flexible joints?
Stainless steel 304 is suitable for most water, steam, and air systems. Stainless steel 316 contains molybdenum for better corrosion resistance, making it ideal for chemicals, seawater, wastewater, or coastal environments.
Does Tan Dat fabricate flexible joints with custom lengths and flange types?
Yes. As a direct manufacturer, we accept 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
Flexible joint with stainless unions, female & male threads belongs to our threaded & union flexible joints range. Material: 304 stainless steel (316 on request), end connection: Union, Female / male thread, Flare end. 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
- Sanitary clamp ends are quick to dismantle and easy to clean for food and pharma lines
- 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
- Choose the clamp gasket material (EPDM, silicone, PTFE) for the temperature and cleaning chemicals
- For chloride, sea water or strong chemicals consider upgrading to SS316
- When ordering, share pressure, temperature, medium and installation size for an accurate quotation
