Connection of pipes and components

 

Pull-ring with sealant (mastic)

 

 

Available from diameter 80 mm up to diameter 630 mm.
Different profiles for pipes and components with 1 mm, 2 mm and 3 mm wall-thickness. Available in galvanized steel.

Inside the pull-ring there is a sealant being physiologically safe and temperature resistent up to 80 degree C.

Easy and quick to assemble.

Application: gravitational bulk good conveying and de-dusting and air extraction plants with pressure differential up to approx. 5000 Pa (500 mm water gauge). If higher pressure tightness is required please use pull-rings for U-shaped seals.

The connection is shock explosion proof up to 3 bar overpressure when using pipes and components up to diameter 300 mm with galvanized pull-rings (certified).When using pull-rings made of stainless steel, the tightness against shock explosions is increased up to 6 bar.

 

Quick Connect pull-ring & pull-ring
without sealant, for U-shaped seals

 Available from diameter 80 mm up to 400 mm.
Same profile of pull-rings for pipes and components with 1 mm and 2 mm wall-thickness. Available in mild steel galvanized and stainless steel.


 

 

In order to make the connection tight a U-shaped seal for 1 mm or 2 mm thick pipes and components is required, which has to be slipped over one of the machine-lip flanges. U-shaped seals are available in various qualities due to different chemical and thermal consistences.

The connection is condensate tight. Leakages are far below the admissible values (acc. to DIN 24194, tightness grade IV - for conveying systems with highest requirements).

It is shock explosion proof up to 3 bar when using respective pipes and components (1,5 mm - 2 mm wall-thickness) up to diameter 300 mm (certified).

Pipes and components with a larger diameter than 300 mm can be used with a loose-flange connection (which is certified up to diameter 630 mm).

The conventional working pressure for the pull-ring connection with U-shaped seal is up to 250 mbar = 25.000 Pa = 2.500 mm water gauge.

However, it has partly been used up to 1 bar.


 

Push-in pipes connection, 1 mm - 2 mm wall-thickness

In order to create special length when assembling.

In order to connect the push-in pipe with a normal pipe a pull-ring or a Quick Connect pull-ring without sealant for 1 mm + 2 mm and a ring-seal are required.

When using 3 mm thick pipes and components a clamping-ring and a rubber bead ring have to be used instead of pull-ring and ring-seal.

The connection is not shock explosions proof.

Admissible pressure differential inside the pipe system is 100 mbar, higher values on request.

The connection is not suitable for axial loads, the pipes and components have to be protected against dislocation when having a higher pressure differential.


Loose flange connection

 

 

 

Available from diameter 350 mm up to 800 mm, for pipes and components with 1 mm up to 3 mm wall-thickness.
Available in mild primed steel, mild galvanized steel or stainless steel.

To make the connection tight a u-shaped seal is required, which has to be slipped over one of the 10 mm high machine-lip flanges. U-shaped seals are available in various qualities and suitable up to 200 degree C.

The flange connection is shock explosion proof up to 3 bar when using respective pipes and components up to diameter 630 mm (certified).

Pipes with welded-on flange on request.
