90° PVC Elbow F/F Solvent Weld

90° PVC Elbow F/F Solvent Weld Codital (Reference: 5890) - In the world of hydraulic fittings, this 90-degree PVC-U elbow stands as a fundamental component for any installation requiring a precise change of direction. Manufactured by Codital, a recognised reference in the PVC fittings sector, this product benefits from ACS certification (Attestation de Conformité Sanitaire) guaranteeing its compliance with the strictest standards for contact with drinking water.

Applications and benefits

This 90° F/F PVC elbow finds its place in a multitude of professional and domestic applications. In drinking water supply, it allows architectural obstacles to be bypassed while maintaining the sanitary quality of the water thanks to its ACS certification. Professionals in agricultural irrigation appreciate it for its UV resistance and its ability to withstand pressure variations related to watering cycles.

In the field of swimming pools and spas, this fitting ensures optimal water circulation in filtration and treatment circuits. Chemical and food industries find a reliable component, resistant to numerous chemicals while meeting the most rigorous hygiene requirements. Its female-female design facilitates integration into existing networks without requiring additional adapters.

Technical specifications and materials

Made from unplasticised PVC-U, this elbow has a stable molecular structure that gives it exceptional resistance to corrosion, chemical agents and thermal variations. PVC-U, unlike plasticised PVC, contains no plasticisers, thus avoiding any risk of substance migration into the transported fluids.

Compliant with standard EN 1452 for plastic piping systems, this fitting meets the requirements of PN16 pressure rating, i.e. a nominal pressure of 16 bar at 20°C. This classification ensures safe use in most common domestic and industrial installations. The range of available diameters from 16mm to 315mm covers all needs, from small domestic installations to large industrial networks.

The 90° angle is machined with industrial precision, ensuring a perfect connection with PVC pipes of the same series. The female sockets are designed to receive pipes according to standardised tolerances, guaranteeing lasting watertightness after bonding.

Installation and implementation

The installation of this solvent weld PVC elbow requires adherence to a precise procedure to ensure the watertightness and longevity of the assembly. Begin by checking the compatibility of the diameter with your existing pipes and ensure that the surfaces to be assembled are clean, dry and free from any traces of grease or dust.

Chamfering the pipes at 15° over a length of 2 to 3mm facilitates insertion and prevents adhesive build-up in the socket. Use a PVC adhesive specially formulated for pressure applications, applying a uniform coat on the pipe and inside the socket. The assembly must be carried out quickly after applying the adhesive, with a quarter-turn rotating movement to ensure even distribution of the adhesive.

Allow a minimum curing time of 15 minutes before handling and wait 2 hours before pressurising for small diameters, up to 24 hours for large diameters. Ambient temperature directly influences these times: in cold weather, extend the setting times.

Expert advice and product synergies

To optimise your installations, pair this elbow with pressure PVC pipes of the same series to guarantee perfect dimensional compatibility. Consider adding repair couplings to your stock for emergency interventions, and consider eccentric reducers for diameter changes while maintaining the alignment of the lower pipe surfaces.

In irrigation, combined use with ball shut-off valves allows precise flow control in each sector. For buried installations, protect the fittings with fine sand to avoid mechanical stress due to ground settlement.

Pay attention to thermal expansion: plan for fixed points and expansion compensators for long pipelines exposed to temperature variations. In industrial environments, check the chemical compatibility with the transported fluids and comply with maximum operating temperatures. Permanent marking of networks facilitates maintenance and future interventions.
