Description
Technical specifications of DN200 PN16 flanged flexible joint with swivel flange
The DN200 stainless steel flexible joint using the PN16 standard flange connection plays a core role in connecting large-scale industrial pipe sections. A notable technical feature of this device is its structure, which combines one fixed flange end with one flexible swivel end. This design thoroughly solves the problem of bolt hole alignment when installing large-diameter rigid pipes, minimizing installation stress on valves and machinery.
The hose body is corrugated from 304 or 316 stainless steel and covered with a load-bearing stainless steel braided layer. This construction allows the hose to maintain the necessary flexibility to absorb vibrations while sustaining the PN16 rated pressure in continuously operating systems. The Tan Dat mechanical workshop performs pressure testing and 100% visual inspection of products before shipment to ensure technical standards.
Selection guide and installation notes for engineers
When incorporating the DN200 flexible joint into system design drawings, engineers should consider the following important technical factors:
- Determine length: The length of the joint is fabricated according to the actual requirements of each installation location to ensure precise thermal expansion compensation.
- Installation position: Usually placed near equipment that generates strong vibrations such as industrial pumps, air compressors, or installed at pipe diversion points and areas crossing building settlement joints.
- Pipe fixation: Sturdy pipe supports must be installed at both ends of the flexible joint to prevent excessive axial expansion that could affect the equipment's service life.
- Bolt tightening force: When tightening the flanges, perform it diagonally and evenly so that the force is distributed uniformly on the sealing gasket.
Comparison of installation options: Swivel flange vs. Double fixed flange
| Technical criteria | 1 fixed end, 1 swivel end type | 2 fixed flange ends type |
|---|---|---|
| Ease of flange hole alignment | Very high thanks to the free-sliding flange ring | Low, requires high-precision alignment |
| Installation time | Fast, labor-saving | Longer if flange holes are misaligned |
| Installation stress | Low, no hose twisting | Prone to stress if there is a large margin of error |
Production and custom fabrication process at the Tan Dat workshop
As a direct manufacturer in the Ho Chi Minh City area (Facility at Vo Van Van, Tan Vinh Loc Commune), Tan Dat Flex quickly meets all specific technical requirements from construction units. Customers can flexibly order fabrication regarding:
- Materials for the corrugated hose and flanges (switching between 304 and 316 stainless steel depending on the corrosiveness of the fluid).
- Overall length dimensions suitable for the limited space of technical tunnels or factories.
- Flange connection standards according to the specific technical requirements of the project.

Frequently asked questions about flanged flexible joints
What is the pressure rating capacity of the stainless steel flexible joint?
Standard 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 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, making it ideal for chemicals, seawater, wastewater, or marine environments.
Does Tan Dat custom-make flexible joints with specific lengths and flange types?
Yes. As a direct manufacturer, we accept custom fabrication for any length, DN15 – DN300 (larger upon request), with JIS, BS, ANSI, DIN flanges, threaded ends, unions, and clamp connections. Call 0906 304 114 for a quote.
