Hawle flange adapter Synoflex 7994 DN450 398-442 mm

When connecting non-dedicated pipes, such as cast iron or AC pipes, dimensional and compatibility problems with couplings arise. Hawle addresses these challenges with the Synoflex series. For example, older pipes, such as asbestos cement and cast iron, can be connected to modern pipes, such as PE and PVC. In addition, they have a long lifetime and are quick, safe and easy to install. Because time and costs are saved, the Hawle Synoflex coupling is an all-round coupling and an essential product in pipeline engineering.

Application

7994 flange adapters are suitable for PE80/100 pipes (according to EN 12201, DIN 8074). In accordance with EN 14525, Synoflex flange adapters can be used with a variety of pipe materials including steel, PE, PVC, steel, cast iron and AC (AC restraint cannot be guaranteed). The flange bore is according to EN1092 PN10. This flange adapter has a DN 450 flange on one side and has a restraint, wide range connection of DN 450 on the other side. The size range of this connection is minimum 398 mm to maximum 442 mm. With a gasket of EPDM, the flange adapter is suitable for drinking water up to PN16.

Product Features

To prevent abrasion or significant damage from chemicals or corrosion, Synoflex flange adapters are made of ductile iron with an epoxy powder coating. The grip ring ensures that the pressure is evenly distributed over the pipe, resulting in minimal constriction on the pipe, a unique feature compared to other couplings on the market. An additional advantage is that the Synoflex couplings do not require a support liner for PE pipes with an SDR class of <21. Furthermore, the Synoflex coupling is capable of absorbing an angular deflection of up to 4° over the entire size range.
