AYVAZ DBKF-30 Stainless Steel Externally Pressurized Expansion Joint
Reliable axial movement control for high-temperature steam and hot water lines.
AYVAZ DBKF-30 Stainless Steel Expansion Joint effectively controls thermal expansion in pipelines under high temperature and pressure. In addition, its fully stainless steel construction delivers superior corrosion resistance. Therefore, it provides a dependable solution, in particular for superheated water and steam lines.
A DN25 flanged connection to DIN/EN standards simplifies mounting, while the 30 mm expansion capacity absorbs large axial movements without difficulty. Moreover, the externally pressurized design stops bellows convolutions from overlapping, consequently minimizing the risk of mechanical damage. It operates at a design pressure of 16 bar and withstands temperatures from -30°C to +200°C. Compliance covers DIN 4014, EN 1594 and EN 1595.
AYVAZ DBKF-30 Stainless Steel Expansion Joint — Technical Specifications
Chemical plant piping and column lines in high-rise buildings suit this product ideally. Furthermore, heating and cooling shafts and pipe bridges frequently specify it. In aggressive environments, the stainless steel body therefore delivers a long service life. In addition, the flanged connection system integrates quickly into standard pipe bridges.
Key Advantages
- Externally pressurized structure prevents damage to bellows convolutions
- Fully stainless steel construction provides maximum resistance to aggressive environments
- Stable and reliable axial movement performance under 16 bar
Applications
- Damping thermal expansion in superheated water and steam lines
- Industrial chemical piping applications requiring corrosion resistance
