Bend 90 Degrees PVC-C Metric PN16 R=2d

  Datasheet (PDF)

The Georg Fischer 90 degrees metric bend in PVC-C (chlorinated polyvinyl chloride) is a high-performance thermoplastic fitting for industrial piping networks that demand controlled hydraulics and durable chemical resistance at elevated temperatures. Unlike a standard 90 degrees elbow, which forces an abrupt change of direction and generates localised turbulence, this fitting is built with an extended bending radius of R = 2d, the radius being equal to twice the nominal outside diameter of the pipe. The swept geometry provides a gradual flow transition that reduces head loss, limits turbulence and cavitation, and improves pump efficiency on high-velocity liquid transport lines.

Injection-moulded in PVC-C in Agate Grey (RAL 7038), the bend resists aggressive chemical media including concentrated mineral acids, strong alkaline solutions and industrial salts. At continuous service temperatures up to 80 degrees Celsius under pressure, PVC-C clearly outperforms standard PVC-U in thermal stability and mechanical rigidity. The fitting is rated PN16 (16 bar at 20 degrees Celsius) across the metric range from d20 to d160 mm, while the d225 size is supplied in the short pattern execution with R = 0.75d at PN10.

Connection is made with metric solvent cement sockets held to ISO 727 and ISO 15493 dimensional tolerances, which guarantees a consistent interference fit and a homogeneous chemical fusion with metric PVC-C pipe. The moulded internal surface is smooth, preventing scaling, sediment build-up and loss of flow capacity over decades of service. Joints bonded with compatible solvent cement and primer withstand pressure surges and the stress of repeated thermal cycling.

Typical applications include chemical dosing and distribution, electroplating and surface treatment, wastewater neutralisation, demineralised and ultra-pure water supply, and marine process systems.
