Threaded Reducing Socket Rp PVC-U PN16

  Data Sheet |   Product Range | Instructional Video

This threaded reducing socket Rp PVC-U is an industrial-grade pipe fitting engineered for diameter transitions within rigid thermoplastic piping networks. Manufactured from unplasticised polyvinyl chloride (PVC-U) by Georg Fischer, this precision component features cylindrical internal parallel threads (Rp) conforming to ISO 7-1 and EN 10226-1 standards on both ends. Rated for a nominal pressure of PN16 (16 bar at an operating temperature of 20 degrees Celsius), it delivers leak-tight mechanical connections without requiring solvent cement, facilitating streamlined assembly and future pipeline modifications in demanding fluid handling environments.

The unplasticised formulation offers outstanding chemical resistance against aggressive media, including diluted and concentrated acids, alkalis, brine, and saline solutions across an operating temperature spectrum from 0 to 60 degrees Celsius. In accordance with ISO EN 1452-3 manufacturing specifications, the fitting exhibits high mechanical rigidity, low surface roughness, and total immunity to galvanic and electrochemical corrosion. Its smooth internal surface prevents encrustation and lime build-up, maintaining laminar hydraulic flow characteristics and minimal pressure loss throughout its operating lifecycle.

Designed specifically for industrial piping infrastructure, water treatment plants, chemical dosing skids, and agricultural micro-irrigation headers, this threaded reducer provides dependable service where metal alternatives suffer from rapid corrosion. Joint integrity requires proper thread sealing using virgin PTFE tape; chemical thread pastes and solvent compounds incompatible with PVC-U polymers must be avoided to eliminate the risk of environmental stress cracking. As an authorised Georg Fischer distributor, BigWeld supplies these PN16 components with complete technical traceability for engineering installations.
