NORHAM Flexible couplings DC
Specifications

The NORHAM Flexible coupling DC is a flexible EPDM sleeve with grade 1.4301 (304) end clamps (with options: Nitrile (NBR), grade 1.4401 (316) austenitic stainless steel).
that allows pipes of similar diameters to be connected where the shear risks are low.
- It is equipped with the "CLIP-IN", a patented EPDM-profile system that helps to hold the stainless steel clamping bands onto the coupling during transit and installation ;
- Available from DN 32 to 275 mm, it is suitable for plumbing and drainage systems.
- It is perfect for use on low pressure networks (0.6 bar max) such as :
- Plumbing and building drainage systems,
- Sewerage and drainage systems,
- Other non-pressure pipe systems,
They can be installed inside as well as outside of buildings and can be laid above ground or buried.
They are suitable for use at operating temperatures between -40°C and + 140°C.
The couplings from the NORHAM Flexible coupling DC range have the European Technical Approval no.09/0248 and the Technical Application Document no.17.2/10-225_V1 (ask us for relevant references).

INSTALLATION

To install NORHAM Flexible coupling DC, make sure that you have a standard screwdriver (up to ND 300, above please use a ratchet).
- Draw a mark that corresponds to half of the width of the coupling onto the largest pipe.
- Then slide the coupling onto this pipe,
- Bring the second pipe as close as possible, making sure that they are well-aligned.
- Slide the NORHAM Flexible coupling DC coupling as far as the marking.
- Tighten the worm drives on the clamping bands to the recommended torque.
The recommended torque setting is indicated on the coupling’s label and in the laying instructions supplied with the coupling.
Example of application: Integration of the NORHAM Flexible coupling DC coupling with a geomembrane “funnel”.
