RFLEX - Flange Adaptors

RFLEX - Multi-Material Large Tolerance PN25 Locked Flange Adapter

Application

Couplings, Flange Adaptors, Repair Collars and Dismantling Joints

Product family

Couplings and assembling

The RFLEX range of multi-material, wide tolerance flange adapters guarantees a tight seal and high tensile strength on all types of cast iron, steel, and plastic pipes from DN50 to DN250 PN25.

Very quick and easy to install, RFLEX allows independent adjustment of the locking and sealing mechanisms.

Independently adjustable C40 hardened steel inserts ensure locking. The clearance between the screw and the insert guarantees optimal positioning of the insert on the pipe surface when tightening. The specific shape of the teeth allows for clamping that guarantees high tear resistance. The insert can be mounted and dismounted without damaging the coating. The possible angular deviation is ±4°.

The 8.8 corrosion-resistant steel tie rods connect the flange to the fitting. They compress the seal to achieve a perfect seal. The EPDM seal is truncated conical, which ensures optimal positioning on the pipe while allowing a tolerance of up to 26 mm on the outer diameter.

The part is coated with Rilsan® 11, a high-performance biological polyamide made from renewable castor beans. This coating offers an exceptional level of versatility, safety, durability, and resistance to permeation.

Features

Product description

1- Connection flange

ISO PN16 flange made of carbon steel coated with RILSAN®11. The conical inner end ensures uniform compression of the seal without creep.

2- Gasket
Truncated cone-shaped gasket that fits perfectly between the connector body and the pipe.

3- Locking insert
Made of GEOMET-coated C40 hardened steel, it locks the pipe with high tear resistance thanks to the special profile of the teeth. The clearance between the screw and the insert ensures optimal positioning of the insert on the pipe surface when tightening. The insert can be mounted and dismounted without damaging the coating.

4- Compression tie Made
of 8.8 steel with anti-corrosion treatment, it brings the flange and the fitting closer together to compress the seal and ensure the adapter is watertight.
