CPVC Reducing Tee

Product Overview
CPVC reducer tees are manufactured from high-purity chlorinated polyvinyl chloride (CPVC) in compliance with GB/T 18993.2 standards. The main pipe nominal diameter ranges from 25 to 200 mm, with a branch pipe reduction ratio of 1:0.6 (e.g., 50 mm main pipe paired with 32 mm branch pipe). with a working pressure ≤1.6MPa. Compatible with chemical pipes of the same material, it enables fluid diversion/convergence with a sealing surface roughness Ra≤0.8μm.

Fitting Features
Integrated injection-molded construction with tensile strength ≥52MPa and impact strength ≥10kJ/m²;
Stable operation from -40°C to 90°C;
Resistant to 95% sulfuric acid and 30% sodium hydroxide corrosion;
97% compatibility with CPVC pipes;
Smooth inner walls (roughness 0.01μm) with no dead corners;
30% lower fluid resistance than steel tees;
Flame-retardant with oxygen index ≥40%. with a smooth inner wall (roughness 0.01mm) and no dead corners. Fluid resistance is 30% lower than steel tees, with a flame retardant oxygen index ≥40%.

Manufacturing Process
CPVC resin with polymerization degree ≥1000 is selected. Precision injection molding at 190-210°C (mold accuracy ±0.05mm) is employed. Graduated wall thickness design (thick wall ≥2.5mm) is applied to reducer sections. Gradual cooling at 25-35°C for final shaping. Each unit undergoes 1.5 times nominal pressure hydrostatic testing (30-minute pressure retention with zero leakage). Deburring and packaging follow successful testing.

Application Scenarios
Chemical Industry: Used for diverting acidic and alkaline fluids in chemical workshops. Main and branch pipes accommodate varying diameter requirements. Resists high temperatures up to 90°C and strong corrosion. Provides reliable sealing at 1.6MPa pressure, ensuring precise fluid distribution.
Pharmaceutical Industry: Connects pharmaceutical intermediate transport pipelines. Meets health standards GB/T 17219 with residue-free inner walls to prevent medium contamination. Facilitates fluid convergence/divergence operations in pharmaceutical production.
Electronics Industry: Compatible with electronic chemical circulating water systems. Resists chemical corrosion with low fluid resistance. Meets component cooling water flow divergence requirements to ensure circulation efficiency.
Electroplating Industry: Used in electroplating waste liquid treatment pipelines, withstands strong corrosion from waste liquids. Its reducer structure adapts to varying pipe diameters across treatment stages, reducing clogging risks and enhancing waste liquid processing efficiency.
Industrial Water Supply: Connects industrial hot/cold water pipelines, operates stably from -40°C to 90°C with 1.6MPa pressure resistance. Enables water flow distribution to different usage points, facilitating system adjustments.

Usage Precautions
Clean pipe fittings and pipe surfaces before installation to remove grease and impurities. Use specialized CPVC adhesive for bonding, applying an even layer (1-1.5mm). Adjust drying time based on ambient temperature (3-5 minutes at 25°C). Avoid operation beyond 90°C or 1.6MPa. Prevent severe impacts on reducer sections. Periodically inspect joint integrity; replace fittings immediately upon detecting leaks.
