Product Overview

The CPVC Union (Solvent Cement) is an detachable pipe connector engineered for industrial CPVC pipeline systems. Molded from chlorinated polyvinyl chloride (CPVC), this CPVC union delivers superior temperature resistance up to 95 deg C combined with excellent corrosion resistance against most acids, alkalis, and oxidizing media. The CPVC union joins pipe segments through solvent cement welding, producing homogeneous joints that match the parent pipe in pressure capability. With a diameter range from DN15 - 110mm and pressure ratings up to PN10, PN16, the CPVC union is specified in chemical processing, semiconductor fabrication, food and beverage, and high-purity water distribution where higher operating temperatures rule out conventional UPVC fittings. Each CPVC union complies with ASTM D2846, ISO 15877 dimensional standards, ensuring full compatibility with standard CPVC pipe and fittings in industrial piping networks.

Key Features

High Temperature CPVC Body: The CPVC union is molded from chlorinated polyvinyl chloride that withstands continuous service temperatures up to 95 deg C, outperforming standard UPVC fittings in hot process lines.
Solvent Cement Socket Ends: Precision-bored socket ends match ASTM D2846, ISO 15877 dimensions, allowing the CPVC union to be joined with solvent cement that fuses fitting and pipe into a homogeneous, leak-free connection.
Broad Chemical Resistance: CPVC material resists most acids, alkalis, and oxidizing media, making the CPVC union suitable for aggressive chemical transfer lines.
Smooth Bore Design: The molded CPVC union features a smooth internal surface that minimizes pressure drop and prevents sediment buildup.
PN16 Pressure Rating: Rated for industrial working pressures up to PN10, PN16, the CPVC union performs reliably in pressurized chemical and water distribution systems.
Corrosion-Free Service Life: Unlike metal fittings that rust and scale, the CPVC union maintains dimensional stability and clean surfaces over decades of service in corrosive environments.

Production

Raw Material

The CPVC union is injection molded from virgin CPVC compound meeting ASTM D2846, ISO 15877 specifications. Material lot certificates document chlorine content, density, and Vicat softening temperature for full traceability.

Molding Process

CPVC Union (Solvent Cement)s are produced on precision injection molding machines with closed-loop control of melt temperature, injection pressure, and hold time. Socket dimensions are gauged to ASTM D2846, ISO 15877 tolerances, ensuring consistent interference fit with CPVC pipe.

Quality Control

Each CPVC union undergoes dimensional inspection of socket bore, body geometry, and wall thickness. Hydrostatic burst testing on sample lots verifies pressure capability exceeding PN10, PN16, with full traceability to material lot and mold cavity.

Applications

Industrial Chemical Processing

The CPVC union routes hot acid and caustic transfer lines around equipment and structural obstacles, withstanding temperatures and concentrations that would degrade UPVC fittings within months.

High-Purity Water Systems

Semiconductor and pharmaceutical plants use the CPVC union in polished water loops where high-purity CPVC prevents ionic contamination and supports hot sanitization cycles.

Electroplating Industry

Hot plating baths and rinse lines specify the CPVC union for piping carrying acidic electrolytes, chromic acid, and nickel solutions at elevated temperatures.

Food and Beverage

The CPVC union handles hot CIP (Clean-In-Place) solutions and process fluid redirection in food and beverage plants, with material compliance supporting hygienic pipeline standards.

Pulp and Paper

Bleach plant and digester auxiliary lines in pulp mills use the CPVC union to navigate hot chlorine dioxide and caustic lines where metal fittings suffer rapid corrosion.
