Plastic tees are pipe fittings, typically made of plastic materials such as polyvinyl chloride (PVC) and polypropylene (PP). They are used for branching or merging in piping systems and are widely used in construction, chemical, agricultural irrigation, and water supply and drainage systems. The testing scope for plastic tees includes PVC tees, PP tees, PE tees, ABS tees, CPVC tees, UPVC tees, PPR tees, PVDF tees, socket tees, threaded tees, flange tees, hot melt tees, electrofusion tees, water supply tees, drainage tees, chemical tees, irrigation tees, air conditioning tees, gas tees, and industrial pipeline tees. Testing items include dimensional accuracy, wall thickness uniformity, sealing performance, pressure resistance, impact resistance, corrosion resistance, thermal stability, environmental stress cracking resistance, melt flow index, density, hardness, tensile strength, flexural strength, compressive strength, Vicat softening point, oxygen index, ash content, moisture content, color stability, and thread accuracy. The testing instruments include electronic universal testing machines, impact testing machines, pressure testing machines, heat distortion temperature testers, melt flow indexers, densitometers, hardness testers, thickness gauges, spectrometers, microscopes, environmental test chambers, and sealing performance testers. The testing methods include dimensional measurement methods, wall thickness measurement methods, sealing test methods, pressure resistance test methods, impact test methods, corrosion test methods, thermal stability test methods, melt flow index test methods, density test methods, hardness test methods, tensile test methods, and bending test methods.
