Types of connections

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.

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.

Available from diameter 350 mm up to 1600 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.

Our 7.5 mm thick segments (bends) of nodular cast iron for wear endangered deflections can be directly attached to a pull-ring for cast iron on the flared angle flanged pipework. Thus, even for a connection of the machine lippe-end pipework to cast iron piping should be done with a welding end with a flared angle flange or alternatively with a welded-on flared angle flang.

Only when subsequently a lipped-end steel segment has to be replaced by a cast iron segment There should be used a loose splitted flared angle flange to compensate the external diameter.
