1. Overview of PVC-U/C Materials
PVC-U (Unplasticized Polyvinyl Chloride, Rigid Polyvinyl Chloride)
Characteristics: High strength, corrosion resistance, lightweight, and cost-effective, suitable for ambient temperature and pressure environments.
Applications: Water supply/drainage pipes, industrial drainage systems, building ventilation ducts, etc.
Limitations: Poor temperature resistance (typically ≤60°C), limited UV resistance (requires stabilizers).
PVC-C (Chlorinated Polyvinyl Chloride)
Characteristics: High temperature resistance (≤93°C), strong chemical corrosion resistance (acids, alkalis, oils), excellent flame retardancy.
Applications: Chemical fluid transport, thermal pipelines, fire protection systems, and other harsh environments.
Advantages: Higher mechanical strength and longer service life compared to PVC-U.
2. Fittings and Valves
Fittings
Function: Connect, branch, or change pipe direction, including elbows, tees, flanges, couplings, etc.
Material: Typically matches the pipe material (PVC-U/C), connected via adhesives (solvent cement) or rubber seals.
Standard Design: Compliant with international dimensional specifications (e.g., ISO 4200) for interchangeability.
Valves
Types: Gate valves, butterfly valves, ball valves, check valves, etc., made of PVC-U/C or metal-lined plastics.
Function: Control flow, pressure, and medium direction, suitable for precise regulation in industrial processes.
Sealing Technology: Rubber seals or PTFE liners to meet diverse medium requirements.
