SCH8O/DIN UPVC/CPVC Reducer Coupler Industry knowledge

Application scenario analysis of UPVC/CPVC reducers in industrial piping systems

In industrial piping systems, UPVC (unplasticized polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride) reducers (Reducer Coupler) are widely used in multiple industries due to their corrosion resistance, lightweight, and easy installation. Different industries have different requirements for the temperature resistance, chemical resistance, and sanitation level of pipes, so it is crucial to choose the right material (UPVC or CPVC) and reducer solution. The following is an analysis of typical application scenarios:

1. Safe Drinking Water & Drinking Water
UPVC reducer: suitable for normal temperature drinking water transportation, meets sanitation standards, and is used for pipe diameter conversion in municipal water supply and building water supply systems.
CPVC reducer: performs better in high-temperature drinking water (such as solar water heating systems), with a temperature resistance of more than 90°C, avoiding the risk of thermal deformation.

2. Metallurgy
Metallurgical plants often involve acidic wastewater and cooling water circulation systems. CPVC reducers are suitable for reducing the diameter of pipes such as sulfuric acid and hydrochloric acid due to their stronger chemical corrosion resistance.

3. Photovoltaic
High-purity chemicals (such as hydrofluoric acid) are required in the manufacture of photovoltaic modules. CPVC reducers can withstand strong acids and are used for reducing the diameter of etching and cleaning process pipelines.

4. Nuclear Power
Low-level radioactive wastewater treatment pipelines in nuclear auxiliary systems need to be corrosion-resistant. CPVC reducers can be used for pipe diameter adjustment in non-core areas due to their radiation aging resistance.

5. Electronic Semiconductor
Ultrapure water delivery and chemical distribution systems require no pollution. The high-finish inner wall of UPVC/CPVC reducers can reduce particle deposition and is suitable for high-precision pipelines in wafer plants.

6. Medicine
Pharmaceutical purified water and water for injection (WFI) systems must comply with GMP standards. CPVC reducers are ideal for high temperature sterilization (such as 121°C steam flushing).

7. Industrial Water Treatment
UPVC reducers are widely used for size conversion of pretreatment pipes in reverse osmosis (RO) and ion exchange processes. They are economical and resistant to chlorine corrosion.

8. Industrial Wastewater
Electroplating and printing and dyeing wastewater contains strong acids and alkalis. CPVC reducers can withstand extreme pH environments for a long time, avoiding the rust problem of traditional metal joints.
