CPVC Solvent Cement Reducing Coupler

Key Features of CPVC Solvent Cement Reducing Coupler

• Concentric double socket joins CPVC pipes of two different diameters.
• Both ends bond with CPVC solvent cement into permanent, monolithic glued joints.
• Keeps flow centered at the diameter change with a smooth molded taper.
• Long-term service up to 90°C; resists acids, alkalis, salts and oxidizing media.
• Replaces fabricated swaged transitions; no threads, gaskets or hot work.

Manufacturing Process of CPVC Solvent Cement Reducing Coupler

Each CPVC Solvent Cement Reducing Coupler is injection molded as one CPVC piece with a concentric internal taper, then both sockets are reamed and gauge-inspected before solvent-cement bonding. Solvent cement is applied to the cleaned socket and pipe spigot, which are then held until the glued joint cures into a single continuous CPVC structure.

Critical Process Parameters of CPVC Solvent Cement Reducing Coupler

• CPVC compound is processed inside its narrow melt-temperature window to avoid degradation.
• Socket inner diameter and spigot interference are controlled to the CPVC solvent-cement fit tolerance.
• Cement coating is even and full-length; set and cure times follow the cement manufacturer schedule before pressure testing.
• Wall-thickness uniformity and roundness are checked to safeguard pressure rating.
• 100% visual and dimensional inspection, with batch pressure and hydrostatic testing.

Raw Material Characteristics of CPVC Solvent Cement Reducing Coupler

• Body in CPVC (chlorinated polyvinyl chloride), joined with CPVC solvent cement.
• Long-term service temperature up to 90°C, well above conventional UPVC.
• Excellent resistance to acids, alkalis, salts and many oxidizing media.
• Flame retardant and self-extinguishing with a high limiting oxygen index (LOI).
• Smooth non-scaling inner surface keeps flow efficient and biofilm low.

Typical Applications of CPVC Solvent Cement Reducing Coupler

• Diameter step-downs in potable water distribution and fixture feeds.
• Pump and equipment size transitions in water treatment and RO skids.
• In-line reductions in chemical and acid/alkali process piping.
• Glued reducers in compact ultrapure water systems for pharma plants.
• Corrosive line size changes in seawater and desalination service.

Application Scenarios of CPVC Solvent Cement Reducing Coupler

For joining a larger CPVC pipe to a smaller one in line, the CPVC Solvent Cement Reducing Coupler gives one centered, permanently glued transition in water and corrosive process piping.
