Gas holder diaphragms are used in Wiggins gas holders in steel plants for the temporary storage of converter and blast furnace gas.
Properties:
 With a thickness of 2.2 mm, the diaphragms are
 extremely low-permeating and resistant to
temperatures ranging from -40°C to +80°C
Multi-axial polyamide layer is used as reinforcing
material, delivering great flexibility and high strength
More than 200,000 strokes, service life of over 10 years

Technical
A reciprocating piston moves up and down in the gas holder, adjusting the stored volume to the fill volume and keeping the gas at working pressure.
In all states of movement, ContiTech's diaphragm maintains a tight seal between the gas-holder wall and the piston. |
Material used
Multi-axial layer, coated on both sides with nitrile rubber
Weft angles of diagonal threads can be specified
Absorption of forces from all intended directions
Full tensile force in each thread
Warp, weft and angle can be adjusted
