Key Features
- ASTM SCH40/SCH80 compliant: meets ASTM standards with wall thickness for different pressure ratings.
- Straight size reduction: connects pipes of different diameters with concentric alignment.
- Solvent cement joint: chemical fusion with specialized industrial cement for reliable sealing.
- Industrial-grade corrosion resistance: PVC-U suitable ≤60°C; PVC-C suitable ≤93°C.
Manufacturing Process
High-precision injection molding from PVC-U or PVC-C. Uniform wall thickness in tapered section; concentric sockets. Socket ID, ovality, and chamfer are precision machined for optimal fit with ASTM pipes.
Critical Process Parameters
- Precise machining of socket inner diameters.
- Streamlined tapered section design with uniform wall thickness.
- Coaxiality control of both sockets.
- Control of injection temperature and cooling cycle for stress-free material.
Raw Material Characteristics
- Material Composition: PVC-U (Unplasticized Polyvinyl Chloride) or PVC-C (Chlorinated Polyvinyl Chloride), conforming to ASTM D1784 material standard.
- Material Properties: PVC-U suitable up to 60°C; PVC-C suitable up to 93°C.
- SCH40 standard wall thickness; SCH80 heavier wall for higher pressure.
- Outstanding chemical resistance to acids, alkalis, salts, and organic solvents.
- High mechanical strength and rigidity; excellent internal pressure resistance.
Typical Applications
- Reducing connections in ASTM chemical piping systems.
- Industrial water and wastewater treatment systems.
- Ultra-pure water piping in electroplating and semiconductor industries.
- ASTM industrial cooling water circulation systems.
Application Scenarios
- Straight sections requiring diameter change in ASTM industrial piping systems.
